The purposes of this study were to quantify the amount of opioid medication used postoperatively in the hospital setting after abdominally based microsurgical breast reconstruction, to determine factors that are associated with increased opioid use, and to identify other adjunctive medications that may contribute to decreased opioid use.An electronic medical record data pull was performed at the University of Pennsylvania from November 2016 to October 2018. Cases were identified using Current Procedural Terminology code 19364. Only traditional recovery after surgery protocol patients were included. Patient comorbidities, surgical details, and pain scores were captured. Postoperative medications including non-patient-controlled analgesia opioid use and adjunctive nonopioid pain medications were recorded. Non-patient-controlled analgesia total opioid use was calculated and converted to oral morphine milligram equivalents (mme). Statistical analysis was performed using t test analyses and linear regression.A total of 328 patients satisfied our inclusion criteria. Five hundred forty free flaps were performed (212 bilateral vs 116 unilateral, 239 immediate vs 89 delayed). Bilateral patients used on average 115.2 mme (95% confidence interval [CI], 103.4-127.0 mme) compared with 89.0 mme in unilateral patients (95% CI, 70.0-108.0 mme; P = 0.015). Patients with abdominal mesh placement (n = 249) required 113.0 mme (95% CI, 100.5-125.5 mme) compared with 83.8 mme (95% CI, 68.8-98.7 mme) for patients without mesh (n = 79; P = 0.016). Each additional hour of surgery increased postoperative mme by 9.4 (P0.01). Patients with a nonzero preoperative pain score required 100.3 mme (95% CI, 90.2-110.4 mme) compared with 141.1 mme (95% CI, 102.7-179.7 mme) for patients with preoperative pain score greater than 0/10 (P0.01). Patients with postoperative index pain score ≤5/10 required 89.2 mme (95% CI, 78.6-99.8 mme) compared with 141.1 mme (95% CI, 119.9-162.2 mme) for patients with postoperative index pain score5/10 (P0.01). After regression analysis, a dose of intravenous acetaminophen 1000 mg was found to decrease postoperative mme by 11.7 (P = 0.024). A dose of oral ibuprofen 600 mg was found to decrease postoperative mme by 8.3 (P0.01).Bilateral reconstruction and longer surgery resulted in increased postoperative mme. Patients with no preoperative pain required less opioids than did patients with preexisting pain. Patients with good initial postoperative pain control required less opioids than did patients with poor initial postoperative pain control. Intravenous acetaminophen and oral ibuprofen were found to significantly decrease postoperative mme.

We present a case of a 26-year-old right hand dominant male landscaper with a slow growing right ring finger subungual mass. MRI confirmed a 0.9 × 1.5 × 0.9 cm well circumscribed subungual mass believed to be consistent with a glomus tumor, although size and symptoms were not consistent with that diagnosis. The mass was completely excised and diagnosis of schwannoma was confirmed by H&E histology. A literature search was performed utilizing the term “subungual schwannoma.” Four case reports were found describing this diagnosis in the hand as well as a single case report describing it in the foot. In summary, this is a 26-year-old male who presents with a schwannoma in the unusual subungual location. Although rare, based on our case and the existing literature, subungual schwannomas should be included in the differential diagnosis of a slow growing subungual mass, particularly if symptoms and exam are inconsistent with more common etiologies.

Introduction Mohs surgery and reconstruction has enabled tissue-preserving resection of cutaneous malignancies. The goal of our case series evaluation is to present reconstructive techniques and functional outcomes in patients undergoing digit-sparing treatment for primary melanoma. Materials and Methods A chart review was performed to identify consecutive patients undergoing Mohs surgery and reconstruction for melanoma of the digits. Quality of life (QOL) survey was performed to assess function after the procedure. Results Thirty-two patients (13 hand, 19 foot, Age: 65.03 +/–17.78 years) who were undergoing Mohs surgery were identified. No recurrence was identified with an average follow-up of 16.1 months (1–95 months). The average defect size was 5.79 +/–4.54 cm 2. Reconstruction was performed 0–4 days after resection. The most common techniques included full-thickness skin graft (FTSG) (N = 7), collagen matrix + FTSG (N = 4), and volar advancement flap (N = 7). The reconstructive technique choice appears correlated with defect size (p = 0.0125). Neuro-QOL upper extremity survey results showed a difference that approached statistical significance between patients who underwent digit-sparing treatment (n = 7) versus direct to amputation controls (n = 5) (p = 0.072). No survey differences between digit-sparing treatment (n = 10) and amputation (n = 8) were identified in the lower extremity (p = 0.61). Conclusion Our results show digit-sparing treatment can confirm clear surgical margins and a trend toward improvement in upper extremity function compared with immediate amputation.

BACKGROUND The purpose of this study was to determine what craniometric changes occur to both orbits of unicoronal craniosynostosis patients undergoing fronto-orbital advancement and remodeling, and which of these changes are associated with new onset of postoperative strabismus. METHODS A retrospective analysis was performed of the preoperative and postoperative orbits of 24 unicoronal craniosynostosis patients and the orbits of 24 control subjects, totaling 144 orbits. Eight parameters were evaluated using multivariate logistic regression analysis. One of the parameters was modified orbital index, an indicator of severity of harlequin deformity. RESULTS Significant differences in orbital dimensions and angles were present bilaterally in unicoronal craniosynostosis orbits when compared to controls. Fronto-orbital advancement and remodeling increased the ipsilateral unicoronal craniosynostosis orbital volume from 13,184 ± 2003 mm to 16,220 ± 2323 mm (p < 0.001). Ipsilateral horizontal cone angles were increased from 48 ± 5 degrees to 54 ± 7 degrees (p = 0.004). Ipsilateral vertical cone angles were decreased from 73 ± 8 degrees to 66 ± 10 degrees (p = 0.003). Ipsilateral modified orbital index improved from 0.83 ± 0.06 to 0.88 ± 0.06 (p = 0.003). Three of the 19 unicoronal craniosynostosis patients developed transient postoperative strabismus. Logistic regression analysis displayed a strong significant association between new-onset strabismus and a change in modified orbital index with a coefficient of 30.84 ± 14.51 (p < 0.05). CONCLUSIONS The orbital dysmorphology in unicoronal craniosynostosis is bilateral in nature, and it is not wholly treated with conventional fronto-orbital advancement and remodeling. The severity of ipsilateral orbital dysmorphology is correlated with the incidence of postoperative strabismus following conventional fronto-orbital advancement and remodeling. Future research is needed to develop strategies to mitigate the risk of development of strabismus in this group of patients. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Learning objectives After studying this article, the participant should: 1. Be familiar with local, regional, and free flaps for reconstruction of the hand. 2. Be able to identify potential sources of tissue for vascularized coverage using an algorithmic approach to provide stable and functional reconstruction of the hand. 3. Recognize the controversies and complications unique to flap reconstruction of the hand. Summary The goal of this continuing medical education module is to provide the practicing reconstructive surgeon with a framework in which to think about reconstruction of the hand. The hand has unique functional and aesthetic characteristics that must be considered when choosing the optimal methods for reconstruction. There are a number of reliable local and regional flaps that can be used to treat the hand requiring soft-tissue coverage and/or vascularized bone graft. The "reconstructive ladder," originally described by Mathes and Nahai, is based on the principle of using the simplest approach that adequately restores form and ideally optimizes function. In cases where the simplest techniques prove to be inadequate, local and regional flaps and, ultimately, microsurgical tissue transfer should be considered.

BACKGROUND International adoptees with cleft lip and palate (CLP) are a growing population in the United States. They represent a clinical challenge, presenting at various ages and stages of cleft repair. METHODS A retrospective review of patients seen at the CLP Program at the Children's Hospital of Philadelphia (CHOP) between 1998 and 2012 with a history of international adoption was performed. Demographics, surgical histories, and long-term speech outcomes were reviewed. RESULTS Seventy-four female and 77 male patients were evaluated. Patients were adopted at an average age of 2.3 years (range, 0.4-8.6 years); 80.8% (n = 122) of patients were adopted from China. The rate of international cleft adoption increased by approximately 1.5 patients per year (r = 0.7739, P < 0.001); 13.2% (n = 19) of all subjects with cleft palates had oronasal fistulas (ONFs) that required repair. The ONF rates for primary palatoplasties at CHOP were significantly lower compared to both preadoption repairs (P = 0.002) and postadoption repairs at outside hospitals (P = 0.01); 14.8% (n = 21) of all patients had secondary surgeries for velopharyngeal incompetence (VPI). Rates of secondary surgery for VPI were also significantly lower for primary palatoplasties at CHOP compared to both preadoption repairs (P = 0.0018) and postadoption repairs at outside hospitals (P = 0.0033). CONCLUSIONS International adoptees with CLP are a growing population and are clinically challenging with high ONF rates and high secondary surgery rates for VPI. We recommend expedited repair of unoperated cleft palates in adoptees older than 18 months. Adopted patients with CLP should be rigorously evaluated for the need for speech therapy and secondary surgeries to correct for VPI.

Background Immediate breast reconstruction (IBR) rates continue to rise, yet recent patterns based on race, age, and patient comorbidities have not been adequately assessed. Methods Women undergoing mastectomy only or mastectomy with IBR from 2005 to 2011 were identified in the American College of Surgeons–National Surgical Quality Improvement (NSQIP) data sets. A multivariate logistic regression was performed to determine factors independently associated with receipt of IBR. Thirty-day surgical complication rates after IBR were also assessed. Results Rates of IBR increased significantly over the study period from 26% of patients in 2005 to 40% in 2011. Non-Caucasian race, older age (≥45 years), obesity, and presence of comorbid conditions including diabetes mellitus, current smoking, and cardiovascular disease were all negatively associated with receipt of IBR. Surgical complication rates after IBR were not predicted by non-Caucasian race, older age, or presence of diabetes mellitus. Conclusions This current assessment of IBR using the American College of Surgeons–National Surgical Quality Improvement data sets demonstrates that non-Caucasian and older women (≥45 years) continue to receive IBR at lower rates despite the lack of association of added risk of surgical morbidity.

Mesh reinforcement can reduce hernia recurrence, but mesh selection is poorly understood, particularly in contaminated defects. Acellular dermal matrix has enabled single-stage ventral hernia repair in clean-contaminated wounds but can be associated with higher complications and cost compared with synthetic mesh. This study evaluated the cost-utility of synthetic mesh and acellular dermal matrix for clean-contaminated ventral hernia repairs.A systematic review of articles comparing outcomes for synthetic and acellular dermal matrix repairs identified 14 ventral hernia repair-specific health states. Quality-adjusted life years were determined through Web-based visual analog scale survey of 300 nationally representative individuals. Overall expected cost and quality-adjusted life-years for ventral hernia repair were assessed using a Monte Carlo simulation with sensitivity analyses.Synthetic mesh reinforcement had an expected cost of $15,776 and quality-adjusted life-year value gained of 21.03. Biological mesh had an expected cost of $23,844 and quality-adjusted life-year value gained of 20.94. When referencing a common baseline (do nothing), acellular dermal matrix (incremental cost-effectiveness ratio, 3378 ($/quality-adjusted life years)) and synthetic mesh (incremental cost-effectiveness ratio, 2208 ($/quality-adjusted life years)) were judged cost-effective, although synthetic mesh was more strongly favored. Monte Carlo sensitivity analysis demonstrated that synthetic mesh was the preferred and most cost-effective strategy in 94 percent of simulations, supporting its overall greater cost-utility. Despite varying the willingness-to-pay threshold from $0 to $100,000 per quality-adjusted life-year, synthetic mesh remained the optimal strategy across all thresholds in sensitivity analysis.This cost-utility analysis suggests that synthetic mesh repair of clean-contaminated hernia defects is more cost-effective than acellular dermal matrix.

There are limited population-based studies that examine perioperative factors that influence postoperative surgical take-backs to the OR following free flap (FF) reconstruction for head/neck cancer extirpation. The purpose of this study was to critically analyse head/neck free flaps (HNFF) captured in the ACS-NSQIP dataset with a specific focus on postoperative complications and the incidence of factors associated with re-operation.The 2005-2012 ACS-NSQIP datasets were accessed to identify patients undergoing FF reconstruction after a diagnosis of head/neck cancer. Patient demographics, comorbidities, and perioperative risk factors were examined as covariates, and the primary outcome was return to OR within 30 days of surgery. A multivariate regression was performed to determine independent preoperative factors associated with this complication.In total, 855 patients underwent FF for head/neck reconstruction most commonly for the Tongue (24.7%) and Mouth/Floor/cavity (25.0%). Of these, 153 patients (17.9%) returned to the OR within 30 days of surgery. Patients in this cohort had higher rates of wound infections and dehiscence (p0.01). Medical complications were significantly higher and included pneumonia (12.4% vs 5.0%, p0.01), prolonged ventilation (16.3% vs 4.8%, p0.01), myocardial infarction (2.6% vs 0.6%, p = 0.017), and sepsis (7.2% vs 3.4%, p = 0.033). Regression analysis demonstrated that visceral flaps (OR = 9.7, p = 0.012) and hypoalbuminemia (OR = 2.4, p = 0.009) were significant predictors of a return to the OR.Based on data from the nationwide NSQIP dataset, up to 17% of HNFF return to the OR within 30 days. Although this data-set has some significant limitations, these results can cautiously help to improve preoperative patient optimisation and surgical decision-making.

Background Many patients with successful lower extremity salvage have postoperative functional and esthetic concerns. Such concerns range from contour irregularity preventing proper shoe-fitting to esthetic concerns involving color, contour, and texture match. The purpose of this study is to determine the overall incidence as well as factors associated with an increased likelihood of undergoing secondary, esthetic refinements of lower extremity free flaps and to review current revision techniques. Methods All patients undergoing lower extremity soft tissue coverage for limb salvage procedures between January 2007 and June 2013 at a single institution were included in the analysis. Patients who underwent secondary refinements for lower extremity free flaps were compared with patients not undergoing secondary procedures. Results During the study period, 152 patients underwent reconstruction and were eligible for inclusion. Of these, 32 (21.1%) patients underwent secondary, esthetic revisions. Few differences in patient or case characteristics were noted, although revision patients trended toward being younger, having lower body mass index, with defects secondary to acute trauma located below the ankle. The most common revision was complex soft tissue rearrangement or surgical flap debulking/direct excision (87.5% of patients), followed by scar revision (12.5%), suction-assisted lipectomy (3.1%), laser scar revision (3.1%), and tissue expansion with local tissue rearrangement (3.1%). Conclusion A significant portion of patients desire secondary revisions following the initial procedure. This is especially true of younger patients with below ankle reconstruction. In many patients, an esthetic consideration should not be of secondary concern, but should be part of the ultimate reconstructive algorithm for lower extremity limb salvage.

Acute kidney injury (AKI) is a serious postoperative complication, negatively impacting mortality rates, extending length of stay, and raising hospital costs. The purpose of this study was to examine AKI following open ventral hernia repair (OVHR) using a large, heterogeneous database to determine the incidence and identify risk factors for this complication. Using the 2005–2012 ACS-NSQIP database, patients undergoing open ventral hernia repair were identified by CPT codes. Patients with acute kidney injury within 30 days of surgery were compared to controls by multivariate logistic regression across preoperative and intraoperative characteristics. Of 48,629 open ventral hernia repair patients identified in the dataset, AKI developed in 1.4 % (681 patients). Multivariate logistic regression determined a number of factors associated with AKI. These include WHO Class III obesity (OR = 2.57, p

Methods: A retrospective review of patients with large midline abdominal hernia treated using component separation technique from 2009 to 2013 at General Surgery Department of Kipshidze Central University Hospital was performed. The scoring criteria were wound complications (infection, hematoma, seroma, scin necrosis, secondary healing), time to return to work/normal activities and recurrent hernia. The mean follow-up time was 21 months.

Institutions are now incentivized to decrease rates of preventable readmissions. The purpose of this study was to examine readmissions following open ventral hernia repair (VHR), to ultimately create a model to preoperatively identify high-risk patients. Utilizing the 2011 and 2012 ACS-NSQIP datasets, patients undergoing open VHR were identified by CPT codes. Patients who were readmitted in 2011 within 30 days of the procedure were compared to those who were not with regard to preoperative and operative characteristics. A bootstrap analysis was performed to identify internally validated risk factors to be included in the final logistic regression, which was utilized to create a weighted model to predict the risk of readmission. This model was then validated with VHR patients in 2012. Overall, 10,745 patients were included for model generation. Of these, 850 (7.9 %) patients were readmitted within 30 days. The final bootstrap analysis demonstrated that active smoking, ASA ≥ 3, a history of bleeding disorder or anemia, long operative time, inpatient status, and concurrent panniculectomy were all independently associated with readmission following ventral hernia repair. Significant variables were assigned a weighted score, ranging from 1 to 3. Each patient was then placed into one of four cohorts according to their summed score. The internally validated model [Hernia Readmission Risk (HERR) Score] demonstrated that risk increased in a linear fashion, with the highest risk cohort having a 21 % risk of 30-day readmission. Perioperative predictors of readmission following VHR include smoking, ASA score, operative magnitude, concurrent panniculectomy, and preoperative anemia and bleeding disorders. The presented model based on these factors can aid in perioperative risk stratification for readmission.

There is a need for validated risk models to better stratify surgical site occurrences (SSO) following open ventral hernia repair (OVHR). The addition of more generalizable and validated risk models will serve to improve perioperative care in OVHR patients. We reviewed the 2005–2011 ACS-NSQIP databases identifying encounters for OVHR. The dependent outcome measure of interest was SSO, defined as superficial surgical site infection, deep infection, organ space infection, or wound dehiscence. Multivariate logistic regression of independently associated factors was performed and internally validated using a bootstrap technique. A composite risk score, the Hernia Wound Risk Assessment Tool (HW-RAT) was created using weighted beta coefficients. The HW-RAT was compared to existing models from the literature. A total of 60,187 patients who met inclusion criteria were identified in the 2005–2011 ACS-NSQIP databases. The incidence of SSO in the study was 6.2 % (N = 3,732). SSO risk factors were broken down based on rounded risk scores into the following groups: mild, intermediate, moderate, and severe risk. Severe risk factors related to operative time and degree of wound contamination. Moderate risk factors included class III obesity, component separation, dependent functional status, and inpatient hernia surgery. Patient stratification was performed based on total risk score into HW-RAT risk groups 1 through 5 which demonstrated significant discrimination between and across each group (P

Background Bone transport osteogenesis (BTO), distraction of a free portion of bone across a defect, offers an autologous solution to large cranial defects that may allow treatment without permanent hardware implantation. This study establishes a sheep model to evaluate the feasibility and distraction kinetics of BTO. Methods Subtotal cranial defects (3.5 × 3.5 cm) were created in 10 young adult sheep and a transport segment (3.5 × 2 cm) traversed the defect at varying distraction rates (0, 0.5, 1.0, and 1.5 mm/day) using semi-buried cranial distractors. After a 6-week consolidation period, sheep were euthanized and the resultant bone was analyzed by CT, histology, and mechanical testing. Results Gross examination, histology, and 3D CT revealed that control animals had fibrous nonunion whereas distraction animals had ossified defects with fibrous nonunion at the distal docking site. There was one premature consolidation in the 0.5 mm/day group. The volume of bony regenerate in the 0.5, 1.0, and 1.5 mm/day distraction rate groups was statistically indistinct (P = 0.16). The mean flexural moduli (MPa) of non-decalcified samples from the control cranium, transport segment, and bone regenerate were found to be 4.50 ± 4.9, 6.17 ± 2.1, and 4.14 ± 4.8, respectively (P = 0.24). Conclusions This experiment provides proof of concept for BTO for large calvarial defects in a sheep model. Distraction at a rate of 0.5 mm per day may place individuals at higher risk for premature consolidation, but distraction rates did not have significant effects on regenerate quantity or quality. Future work will include the use of curvilinear distraction devices for 3-dimensional contour.

BACKGROUND Death following surgical procedures, although uncommon, represents the most significant and costly postoperative complication. The authors delineate several key independently associated risk factors for 30-day mortality in a large nationwide plastic surgery population and generate a simple risk-assessment tool. METHODS Patients who underwent a primary plastic surgery procedure (n=24,778) were identified from the 2005 to 2011 American College of Surgeons National Surgical Quality Improvement Program databases. Preoperative patient comorbidities and operative variables were analyzed to determine associations with mortality. Multivariate regression modeling and risk stratification were performed to generate a decision-support tool capable of assessing mortality risk. RESULTS Seventy-eight patients (0.31 percent) experienced 30-day mortality. Age older than 65 years, inpatient surgery, hepatorenal disease, recent chemotherapy, and partial or dependent functional status were perioperative factors associated with 30-day mortality. A composite mortality risk score was used to stratify patients into groups of low (n=18,063) (30-day mortality, 0.06 percent), intermediate (n=1252) (30-day mortality, 0.96 percent), high (n=314) (30-day mortality, 5.10 percent), or extreme (n=126) (30-day mortality, 17.46 percent) risk. The scoring groups accurately separated risk (p

Background Commercially available recombinant human bone morphogenetic protein 2 (rhBMP2) has demonstrated efficacy in bone regeneration, but not without significant side effects. In this study, we utilize rhBMP2 encapsulated in PLGA microspheres (PLGA-rhBMP2) placed in a rabbit cranial defect model to test whether low-dose, sustained, delivery can effectively induce bone regeneration.

Background This study utilizes the American College of Surgeons National Surgical Quality Improvement Program database to better understand the impact of obesity on perioperative surgical morbidity in abdominal wall reconstruction (AWR). Methods We reviewed the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program databases, identifying cases of AWR and examining early complications in the context of obesity (body mass index > 30, World Health Organization classes 1 to 3). Results Of 1,695 patients undergoing AWR, 1,078 (63.2%) patients were obese (mean body mass index=37.6 kg/m 2 ). Major surgical complications (15.3% vs 10.1%, P = .003), wound complications (12.5% vs 8.1%, P = .006), medical complications (16.2% vs 11.2%, P = .005) and return to the operating room (9.1% vs 5.4%, P = .006) were significantly increased, while renal complications (1.9% vs .8%, P = .09) neared significance. On logistic regression, obesity only directly led to a significantly increased odds of having a renal complication (odds ratio=4.4, P = .04). Complications were still noted to increase with World Health Organization classification, including a concerning incidence of venous thromboembolism. Conclusions Although the incidence of complications increased with obesity, obesity itself does not appear to increase the odds of perioperative morbidity. Specific care should be given to VTE prophylaxis and to preventing renal complications.

Groin wound complications after open vascular surgery procedures are common, morbid, and costly. The purpose of this study was to generate a simple, validated, clinically usable risk assessment tool for predicting groin wound morbidity after infra-inguinal vascular surgery. A retrospective review of consecutive patients undergoing groin cutdowns for femoral access between 2005-2011 was performed. Patients necessitating salvage flaps were compared to those who did not, and a stepwise logistic regression was performed and validated using a bootstrap technique. Utilising this analysis, a simplified risk score was developed to predict the risk of developing a wound which would necessitate salvage. A total of 925 patients were included in the study. The salvage flap rate was 11.2% (n = 104). Predictors determined by logistic regression included prior groin surgery (OR = 4.0, p < 0.001), prosthetic graft (OR = 2.7, p < 0.001), coronary artery disease (OR = 1.8, p = 0.019), peripheral arterial disease (OR = 5.0, p < 0.001), and obesity (OR = 1.7, p = 0.039). Based upon the respective logistic coefficients, a simplified scoring system was developed to enable the preoperative risk stratification regarding the likelihood of a significant complication which would require a salvage muscle flap. The c-statistic for the regression demonstrated excellent discrimination at 0.89. This study presents a simple, internally validated risk assessment tool that accurately predicts wound morbidity requiring flap salvage in open groin vascular surgery patients. The preoperatively high-risk patient can be identified and selectively targeted as a candidate for a prophylactic muscle flap.

Background Ventral hernias are a common, challenging, and expensive problem for general and reconstructive surgeons. The authors assessed the impact of epidurals on morbidity following abdominal wall reconstruction for hernia. Methods A retrospective review of abdominal wall reconstruction patients operated on between 2007 and 2012 was performed with a specific focus on the use of epidurals. Bivariate and multivariate logistic regression analyses were used to assess independent predictors of morbidity. Subgroup analyses were also performed. Results The study included 134 consecutive reconstructions performed by a single surgeon over a 5-year period at an academic teaching center. Patient groups were similar in terms of demographics, preoperative characteristics, hernia grade, and intraoperative characteristics. Epidural use was associated with a lower incidence of major surgical complications (19.7 percent versus 36.1 percent; p = 0.04) and medical complications (26.8 percent versus 54.1 percent; p = 0.001). A significant and independent reduction in medical morbidity (OR, 0.09; p ≤ 0.001) and unplanned reoperations (OR, 0.23; p = 0.052), was found with patients receiving epidurals. Furthermore, a notable trend toward reduced major surgical complications (OR, 0.45; p = 0.141) and cost savings (-$22,184; p = 0.01) was found in patients who received epidurals. Subgroup analysis did not demonstrate statistically significant reductions in major surgical morbidity in reconstruction either with (p = 0.13) or without (p = 0.07) concurrent intra abdominal procedures when epidurals were not or were used, respectively. Conclusions Epidural use may be associated with reduced morbidity and cost savings in abdominal wall reconstruction. This effect appears to be related to reduced medical morbidity and shortened length of stay in patients undergoing more complex, concurrent intraabdominal hernia procedures. Clinical question/level of evidence Risk, II.

Background Abdominal wall reconstruction (AWR) poses a substantial operative challenge, often in the setting of multiple failed attempts at repair in high-risk patients. Our aim was to assess risk factors for major operative morbidity after AWR using the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) patient database. Methods A review of the ACS-NSQIP database of outcomes from 2005 to 2010 was performed to identify patients undergoing AWR utilizing Current Procedural Terminology codes for ventral hernia repair and a concomitant component separation. Independent variables included patient demographics, medical comorbidities, and operative considerations. Major operative complication (deep wound infection, graft or prosthetic loss, or unplanned return to the operating room within 30 days) was used as our dependent variable. Stepwise, multivariate logistic regression was performed to evaluate patient risk factors influencing the occurrence of major operative complications. Results We identified 1,706 patients with an average age of 55.9 ± 12.8 years with 30.1% undergoing concurrent intra-abdominal procedures and 57.1% undergoing mesh repair. Notable medical comorbidities included obesity (63.4%), smoking (24.9%), hypertension (53.1%), diabetes (19.9%), and anemia (22.6%). Average operative time was 211.7 ± 105.0 minutes. Regression analysis determined that prolonged operative time (odds ratio [OR], 2.7; P 2 (OR, 1.8; P = .009) were positively associated, whereas advanced age (OR, 0.5; P = .005) was negatively associated with the occurrence of major operative complications. Conclusion Greater operative times and overall patient health are important prognostic factors for individuals undergoing AWR. The increased physiologic stress of a greater operative duration on patients who often have multiple comorbidities seems to play a significant role in predicting negative outcomes after AWR.

Purpose Complex lower extremity wounds present a significant challenge to the reconstructive surgeon. We report a consecutive experience of free tissue transfers for lower extremity reconstruction with a focus on outcomes and flap selection. Methods A retrospective review of all free tissue transfers for lower extremity reconstruction between 2006 and 2011 was performed. Minor complications were defined as nonoperative complications (infection, seroma, hematoma, wound breakdown, and partial loss). Major complication required a surgical intervention (total flap loss, thrombosis, nonunion, amputation, and hematoma). Results A total of 119 free flaps were performed in 114 patients. Reconstructed defects were most commonly derived from acute traumatic (N = 40) or chronic traumatic (N = 34) wounds, oncologic (N = 14), or diabetic (N = 8). Flap loss occurred at a rate of 5.9% and the overall lower extremity salvage rate was 93%. Complications were significantly higher for free tissue transfers to the region of the distal tibia (p = 0.04). Major complications were significantly higher in patients with chronic obstructive pulmonary disease (p = 0.02) and in patients who experienced intraoperative technical difficulties (p = 0.014). Flap loss was significantly higher when the rectus abdominis flap was used (p = 0.02) and when a delayed venous thrombotic event occurred (p = 0.001). Conclusion Patient comorbidities and defect location can be associated with higher rates of complications; flap selection and delayed venous thrombotic events appear to be associated with flap failure.

Background Temporal hollowing occurs frequently following surgical correction of unicoronal synostosis. This is characterized by a depression in the posterolateral orbitotemporal region. Both soft-tissue and bony causes have been postulated to underpin this problem. The authors investigated the soft-tissue and bony morphology of the temporal region in surgically treated unicoronal synostosis patients. Methods A retrospective analysis of adolescent patients with temporal hollowing who underwent unicoronal synostosis repair as infants was carried out. Demographic data and computed tomographic craniometric parameters were obtained and analyzed using the t test. Photographs were graded subjectively and compared with quantitative data. Results Fifteen children (seven boys and eight girls; mean age, 13 years) were identified. Seventeen patients (10 boys and seven girls; mean age, 14 years) were used as controls. The affected side showed temporal constriction, compared with controls, along the supraorbit and anterior temple. The sella-to-pterion distance was also less, but not statistically so. Soft-tissue analysis revealed decreased thickness of the affected temporalis muscle compared with unaffected and control sides (range, 1 to 3 mm less). The affected fat pad width was not statistically different from unaffected and controls. Subjective clinical grading did not demonstrate statistical correlations with quantitative data. Conclusions Temporal hollowing occurs following surgical correction of unicoronal synostosis, despite original overcorrection, because of bony constriction along the anterior bandeau. Decreased thickness of the temporalis muscle may also contribute to this depression, whereas the superficial fat pad does not play a role. Subjective clinical scoring does not strictly correlate with severity of craniometric measurements. Clinical question/level of evidence Therapeutic, III.(Figure is included in full-text article.).

Objective This study uses the American College of Surgeons Pediatric National Surgical Quality Improvement Program (ACS NSQIP Pediatric), a multicenter database, to identify risk factors for complications after cleft palate repair. Design Patients undergoing Current Procedural Terminology (CPT) codes 42200 and 42205 were extracted from the 2012 ACS NSQIP Pediatric. Patients older than 36 months or those who had undergone an additional surgery that altered the risk were excluded. Outcome variables were combined to create a complication variable. Fisher's exact, Pearson chi-square, and Wilcoxon rank-sum tests were used for analysis. Results Eligibility criteria were met by 751 patients. Of these, 192 (25.6%) had unilateral clefts, 146 (19.4%) bilateral, and 413 (55.0%) were unspecified. The average age at time of surgery for those without and with complications was 421.1 ± 184.8 and 433.6 ± 168.0 days, respectively ( P = .76). Of the 21 (2.8%) patients with complications, respiratory complications were the most common. Risk factors associated with complications included American Society of Anesthesiologists classification of 3 ( P = .003), nutritional support ( P = .013), esophageal/gastric/intestinal disease ( P = .016), oxygen support ( P = .003), structural pulmonary/airway abnormality ( P = .011), and impaired cognitive status ( P = .009). Patients undergoing concurrent laryngoscopy ( P = .048) or other surgeries ( P = .047) were also found to be associated with increased complications. The 30-day fistula rate was 0.5%, and the readmission rate was 1.9%. Conclusion Perioperative complications for primary palatoplasty were 2.8% according to the ACS NSQIP Pediatric. Preoperative patient-related factors as well as concurrent surgeries may affect 30-day complication rates. These results help target those at greater risk for complications and allow for appropriate interventions to mitigate risks.

Posterior cranial vault distraction osteogenesis has recently been introduced to treat patients with multisuture syndromic craniosynostosis and is believed to provide greater gains in intracranial volume. This study provides volumetric analysis to determine the gains in intracranial volume produced by this modality.This was a two-center retrospective study of preprocedure and postprocedure computed tomography scans of two groups of 15 patients each with syndromic multisuture craniosynostosis treated with either fronto-orbital advancement or posterior cranial vault distraction osteogenesis. Scan data were analyzed volumetrically with Mimics software. Volumetric gains attributable to growth between scans were controlled for.The mean advancements were 12.5 mm for fronto-orbital advancement and 24.8 mm for distraction osteogenesis. The mean difference in volume between the preoperative and postoperative scans was 144 cm(3) for fronto-orbital advancement and 274 cm(3) for (p = 0.009). After controlling for growth, the corrected mean volume difference was 66 cm(3) for fronto-orbital advancement and 142 cm(3) for distraction osteogenesis (p = 0.0017). The corrected mean volume difference per millimeter of advancement was 4.6 cm(3) for fronto-orbital advancement and 5.8 cm(3) for distraction (p = 0.357).In this retrospective study, posterior cranial vault distraction osteogenesis provided statistically greater intracranial volume expansion than fronto-orbital advancement. The volume gains per millimeter advancement were similar between groups, with a trend toward greater gains per millimeter with distraction osteogenesis. Gradual expansion of the overlying soft tissues with posterior cranial vault distraction osteogenesis appears to be the primary mechanism for greater volume gains with this technique.Therapeutic, III.

Although facial asymmetry in hemifacial microsomia (HFM) is well documented in the literature, no studies have concentrated on the morphology of the cranial base. This study aimed to evaluate the endocranial morphology in patients with HFM. Consecutive patients with unilateral HFM treated at a craniofacial center from 2000 to 2012 were included. The patients were grouped according to severity on the basis of the Kaban-Pruzansky classification: mild (0-1), moderate (2a), and severe (2b-3). Skull base angulation and transverse craniometric measures were recorded and then compared with those of age-matched controls. A total of 30 patients (14 males, 16 females) averaging 7.5 years of age (range, 1.1-15.7 y) were included. Four patients were classified as mild; 12, as moderate; and 14, as severe. The mean cranial base angle was found to be between 179 and 181 degrees with no significant difference between the severity groups (P = 0.57). The mean cranial base angle did not differ significantly in the patients compared with the controls(179.6 vs 180.0; P = 0.51) No significant differences between the affected and unaffected sides in the patients were found in distances from the midline to hypoglossal canal, internal acoustic meatus, lateral carotid canal, medial carotid canal, foramen ovale, and rotundum. There were no significant differences in transverse measurements between the severity classes using the same landmarks (P = 0.46, P = 0.30, P = 0.40, P = 0.25, P = 0.57, and P = 0.76, respectively). The cranial base axis is not deviated in the patients with HFM compared with the age-matched controls, and there exists little difference in endocranial morphologic measurements with increasing severity of HFM. These data are interesting, given the role of the cranial base in facial growth and the varying hypotheses regarding the mechanism of disease in HFM.

Background Although hernia repair with mesh can be successful, prophylactic mesh augmentation (PMA) represents a potentially useful preventative technique to mitigate incisional hernia risk in select high-risk patients. The efficacy, cost-benefit, and societal value of such an intervention are not known. The aim of this study was to determine the cost-utility of using prophylactic mesh to augment fascial incisions. Methods A decision tree model was employed to evaluate the cost-utility of using PMA relative to primary suture closure (PSC) after elective laparotomy. The authors adopted the societal perspective for cost and utility estimates. A systematic review of the literature on PMA was performed. The costs in this study included direct hospital costs and indirect costs to society, and utilities were obtained through a survey of 300 English-speaking members of the general public evaluating 14 health state scenarios relating to ventral hernia. Results PSC without mesh demonstrated an expected average cost of $17,182 (average quality-adjusted life-year [QALY] of 21.17) compared with $15,450 (expected QALY was 21.21) for PMA. PSC was associated with an incremental cost-efficacy ratio (ICER) of −$42,444/QALY compared with PMA such that PMA was more effective and less costly. Monte Carlo sensitivity analysis was performed demonstrating more simulations resulting in ICERs for PSC above the willingness-to-pay threshold of $50,000/QALY, supporting the finding that PMA is superior. Conclusion Cost-utility analysis of PSC compared to PMA for abdominal laparotomy closure demonstrates PMA to be more effective, less costly, and overall more cost-effective than PSC.

Unplanned surgical readmissions represent a benchmark outcome and pose a considerable cost burden for health care systems. The authors evaluated risk factors associated with readmission following pediatric plastic surgery using a prospective, validated, national database.Patients younger than 18 years who underwent primary pediatric plastic surgery procedures were identified from the 2013 pediatric American College of Surgeons National Surgical Quality Improvement Program database.Two cohorts were compared: patients who experienced readmission and those who did not. Patient characteristics, comorbidities, intraoperative details,and 30-day postoperative outcomes, including complications and readmissions,were analyzed. Multivariate logistic regression analysis was used to identify factors associated with readmission.A total of 5376 patients were included, for an overall 2.40 percent readmission rate. The study cohort was, on average, 5.47 ± 5.21 years old,51.60 percent (n = 2774) were male, and 65.92 percent of cases (n = 3544)were outpatient procedures. The average number of relative value units per case was 10.15 ± 8.01. Patients with medical comorbidities (p0.001) and those with a preoperatively contaminated or infected wound were at higher risk for readmission (p0.001). Patients with higher American Society of Anesthesiologists scores (p0.001), longer operative times (p0.001), and longer hospitalizations (p0.0171) were also independently at greater risk for readmission. The most significant independent predictors of readmission were postoperative surgical and medical complications (OR, 6.94 and 11.92,respectively; p0.001).These results help target patients at greater risk for readmission and afford an opportunity to provide evidence-based interventions to mitigate risk and minimize cost burden for health care systems.

The aim of our study is to better understand the maxillary involvement in relation to the mandibular deformation in hemifacial microsomia (HFM). To do so, consecutive patients with HFM treated at The Children's Hospital of Philadelphia from 2000 to 2012 were included in our study. Both two-dimensional and three-dimensional analyses of the bony and sinus structures of the midface and mandible were performed using three-dimensional segmentation software. Patients were stratified into groups based on the Kaban-Pruzansky classification--mild (0-1), moderate (2A), and severe (2B-3)--as well as rank ordering based on overall severity. Analyses involved paired t-tests within severity groups, 1-way analysis of variance when assessing across groups (ipsilateral/contralateral ratio), and regression to assess for trends. Thirty patients were included (4 mild, 12 moderate, and 14 severe). The mandibular volume ratio differed across all patient groups (P < 0.001) and trended with rank order (P < 0.001). No significant difference in maxillary bony volume ratio was found across all patient groups (P = 0.16). In patients with severe disease, the maxillary bone volume was found to be significantly decreased on the ipsilateral side as compared with the contralateral side (P = 0.0123). There was no difference in maxillary sinus volume between ipsilateral and contralateral sides within any patient groups or in comparing across groups (P = 0.10). No significant trend was found in the volume ratio of mandible and maxilla (P = 0.41). To conclude, the maxillary sinus seems to show no difference in volume when comparing between laterality and severity groupings. These findings suggest that there may be alternative influences other than the vascular insult acting as the driving force behind the mandibular deformity and the additional classic clinical findings of HFM.

Complex abdominal wall reconstruction (AWR) is commonly performed, but with a significant rate of surgical complications and hernia recurrence. The aim of this experiential review is to assess risk factors for hernia recurrence after complex AWR. A retrospective review of AWR patients from 2007-2012 was performed. Rates of hernia recurrence were assessed. Univariate analyses and subsequent multivariate logistic regression analysis was used to assess independent predictors of early hernia recurrence. One hundred and thirty-four consecutive cases of AWR were performed over a 5-year period. Hernia recurrence developed in 14 (10.4%) patients. Hernias derived from trauma (OR = 19.76, p = 0.011) and those who experienced postoperative wound infections (OR = 18.81, p = 0.004) were at increased risk for hernia recurrence. In conclusion, increased vigilance must be paid to patients presenting after trauma with massive loss of domain and those who experience postoperative infection, as these cohorts are at added risk for failed reconstruction.

There is continued debate about the outcomes of direct-to-implant (DTI) breast reconstruction when compared to a two-stage expander/implant approach. The purpose of this study was to examine outcomes after DTI reconstruction utilising the American College of Surgeons-National Surgical Quality Improvement (ACS-NSQIP) database. This study reviewed the 2005-2010 ACS-NSQIP databases identifying encounters with common procedural terminology codes for DTI (19340) (mastectomy and immediate implant placement). A composite variable of "major surgical complications" (deep infection, return to OR, device loss) was used as the dependent variable in the analysis. Logistic regression analysis was performed to assess for pre- and intraoperative factors associated with the occurrence of "major surgical complications". Overall, 1612 patients underwent one stage, DTI reconstruction with an average age of 50.8 ± 10.7 years with a body mass index (BMI) (kg/m2) of 26.9 ± 6.3 kg/m2. The incidence of major surgical complications was 9%. A multivariate regression analysis revealed obesity (OR = 1.54, p = 0.03), active smoking (OR = 1.60, p = 0.044), and prolonged operative time (>1 SD above average) (OR = 1.88, p = 0.002) were associated with surgical morbidity. The results of the analysis emphasize that DTI-based breast reconstruction can be an excellent option for a specific group of patients. Careful pre-operative patient selection will optimise outcomes, and caution must be used in assessing suitability of DTI in obese patients and active smokers.

Panniculectomy (PAN) during ventral hernia repair (VHR) can be a challenging procedure associated with added risk. We utilized the ACS-NSQIP datasets to generate a risk model of morbidity following these combined interventions.The 2005-2012 ACS-NSQIP databases were queried to identify all patients undergoing VHR-PAN. Multivariate logistic regression analyses were used to assess perioperative factors associated with surgical and medical morbidity. Internal validation was performed using bootstrap analysis and risk stratification was performed using weighted β-coefficients.1974 patients underwent VHR-PAN with an average age of 53.6 ± 12.4 years and BMI of 36.4 ± 10.1 kg/m2. Surgical complications occurred in 23.8% of patients, whereas medical complications occurred in 11.5%. A multivariate logistic regression identified the presence of a renal comorbidity (OR = 1.62, P = 0.045), class II obesity (BMI = 34.9-40.0 kg/m2) (OR = 1.89, P0.001), class III obesity (BMI≥40 kg/m2) (OR = 2.66, P0.001), dirty/infected wound class (OR = 2.01, P = 0.003), smoking (OR = 1.41, P = 0.026), prolonged operative time (OR = 2.12, P = 0.001), and ASA physical status of ≥3 (OR = 1.69, P0.001) as independently associated with higher incidences of postoperative surgical complications. A multivariate regression analysis identified class II or III obesity (OR = 1.70, P = 0.003), contaminated or dirty/infected wounds (OR = 1.95, P0.001), diabetes (OR = 1.96, P = 0.001), pulmonary comorbidity (OR = 2.08, P = 0.005), and component separation (OR = 2.65, P0.001) as independently associated with higher incidences of postoperative medical complications. Simplified risk models of surgical and medical morbidity demonstrated good discrimination with C statistics of 0.69 and 0.70, respectively.We report a simple preoperative, internally-validated risk model of surgical and medical morbidity following VHR-PAN to guide patient selection.Prognostic/risk category, level II.

BACKGROUND The temporal region is significantly affected by both restricted and compensatory growth in unilateral coronal craniosynostosis. Recurrent deformity in this region after fronto-orbital advancement often requires a revision operation in adolescence. The authors performed a three-dimensional analysis of the temporal region in patients with unilateral coronal craniosynostosis to define the baseline deformity and the immediate and long-term changes after fronto-orbital advancement. METHODS A retrospective analysis of patients with nonsyndromic unilateral coronal craniosynostosis who underwent reconstruction with fronto-orbital advancement or revision cranioplasty after fronto-orbital advancement between 2005 and 2010 was performed. Volumetric and craniometric computed tomographic data were obtained from the bilateral temporal regions and analyzed using the appropriate statistical tests. RESULTS Fifteen patients immediately before and after fronto-orbital advancement and 14 precranioplasty patients were included. In all groups, the supraorbits on the synostotic sides were significantly constricted in the transverse dimension. The temporal fossa volume on the synostotic side was displaced and significantly smaller than the nonsynostotic side in all groups. The temporalis muscle of the synostotic side was smaller but disproportionately large for the temporal fossa. CONCLUSIONS In unilateral coronal craniosynostosis, there is a baseline and persistent deficiency in the transverse dimension of the supraorbit on the synostotic side. The temporalis muscle is smaller on the synostotic side but is disproportionately large for the temporal fossa of the affected side, which is inferolaterally displaced and smaller because of compensatory growth. These subtle abnormalities in the relationships between the bony dimensions and soft tissues appear to contribute to the temporal hollow deformity often observed after fronto-orbital advancement.

Background: As the American population ages, a growing number of women may suffer from symptomatic macromastia in their later years. Objectives: The authors analyzed population data from the 2005-2010 American College of Surgeons National Surgical Quality Improvement Program database to investigate effects of age on 30-day surgical outcomes for reduction mammaplasty with the hope of improving patient care, counseling, and risk stratification. Methods: Overall, 3537 patients were included in the analysis. Outcome variables included 30-day postoperative major surgical, medical, and wound complications. Patients were initially stratified into 2 groups: 60 years as elderly. The authors then performed a subgroup analysis, further stratifying the younger cohort into

The obesity epidemic continues to grow, and we have observed greater numbers of obese individuals among patients seeking lower extremity reconstruction at our institution. These patients may present a greater reconstructive challenge, thus we sought to identify risk factors and differences in outcomes among patients undergoing lower extremity reconstruction. In this study we have performed a retrospective cohort analysis of patients undergoing lower extremity reconstruction with free tissue transfer at our institution from 2005 to 2012. Patients were classified using the World Health Organization criteria for obesity. Records were reviewed for patient characteristics, mechanism of injury, indications for reconstruction, and surgical technique, with a focus on intraoperative and early postoperative complications and outcomes. A total of 43 out of the 119 patients undergoing lower extremity reconstruction were obese (body mass index ≥ 30). Mechanism of injury, wound location, and the indications for reconstruction were similar in both cohorts. No significant differences were found in operative characteristics and techniques, including the type of flap utilized, operative time, or thrombotic events. No significant differences were seen in complication rates overall, however, obese patients more frequently needed second flaps (11.6 vs. 0%, p = 0.005). This study concludes that successful lower extremity reconstruction can be performed in the obese population, with few differences in complication rates and outcomes relative to healthy weight patients.

To examine the limb salvage experience of a young microsurgeon to determine risk factors for complications and demonstrate lessons learned through cases in practice. We performed a retrospective review of lower extremity (LE) reconstruction between 2007 and 2012 performed by the senior author. This analysis focused on medical comorbidities, mechanisms, indications, and perioperative complications. A total of 61 free tissue transfers were performed with a 95% LE salvage rate. The most common donor site was the anterolateral thigh (ALT) (n = 39). Infection (n = 25) and trauma (n = 25) were the most common indications for intervention. A total of 18 complications were reported, with 8 defined as major complications. Total flap loss occurred in three patients. Through increased utilization of the ALT and adherence to lessons learned over time, improvements in outcomes can occur, giving patients the best possible chance at limb salvage.

Morbid obesity is increasing at an alarming rate and a significant portion of patients presenting for complex abdominal wall reconstruction (AWR) and component separation fall into this category, creating added medical and surgical challenges to an already difficult operation. The goal of this study was to utilise the Nationwide 2005-2010 American College of Surgeons National Surgical Quality Improvement database (ACS-NSQIP) to perform a population level analysis of the role of morbid obesity on 30-day perioperative morbidity with the hope of improving patient care, counselling and risk stratification. Morbidly obese patients (BMI40 kg/m(2)) were compared to non-obese patients (BMI30 kg/m(2)). Outcome variables assessed included major surgical complications, major medical complications, major renal complications, major wound complications, return to OR (ROR), and venous thromboembolism (VTE). Significant variables in a univariate analysis were included in a multivariate logistic regression controlling for patient characteristics (p0.05). In total, 1695 patients undergoing AWR were identified in the ACS-NSQIP database. Of these, 614 patients were non-obese (average BMI = 25.7 ± 3.0 kg/m(2)) and 314 were morbidly obese (average BMI = 45.9 ± 5.8 kg/m(2)). Multivariate analyses determined that morbid obesity did not significantly contribute to major surgical, medical, renal or wound complications. However, it was significantly associated with ROR (OR = 2.8, p0.001) and VTE (OR = 5.2, p = 0.04). Morbid obesity is an independent risk factor for ROR and VTE related complications, in the 30 day post-operative period. Additional perioperative care is warranted to decrease such early re-operations and for preventable complications.

BACKGROUND: Ventral hernia remains a continued and expensive problem for general and reconstructive surgeons, alike. The aim of this study was to assess perioperative factors and cost associated with postoperative respiratory morbidity in abdominal wall reconstruction. METHODS: A retrospective review of abdominal wall reconstruction patients operated on between 2007 and 2012 was performed. Analysis of perioperative factors associated with postoperative respiratory morbidity was performed using hospital-defined International Classification of Diseases, Ninth Revision codes. Bivariate and multivariate logistic regression analyses were used to assess independent predictors of postoperative respiratory morbidity, and linear regression was used to determine the financial impact. RESULTS: One hundred thirty-four consecutive abdominal wall reconstructions performed by a single surgeon over a 5-year period were included. Respiratory complications occurred in 15.7 percent of patients (n = 21); 5.2 percent required reintubation (n = 7) and 5.2 percent failed to wean from ventilatory support postoperatively (n = 7). Patients experiencing respiratory morbidity stayed on average 16.2 days longer (p < 0.0001) and represented the only three patients in the study experiencing mortality (p = 0.003). Regression analysis demonstrated that intraoperative blood transfusions (p = 0.008), highest peak intraoperative airway pressure (p = 0.017), fascial closure (p = 0.013), and American Society of Anesthesiologists physical status (p = 0.019) were all associated with postoperative respiratory morbidity. Linear regression analysis demonstrated that respiratory complications added a cost of $60,933 per patient (p < 0.001). CONCLUSIONS: Postoperative respiratory morbidity following abdominal wall reconstruction is a common occurrence linked to identifiable perioperative risk factors and associated with significant mortality and a tremendous cost burden. These findings underscore the importance of preoperative risk stratification and patient selection to optimize outcome and contain cost.

Ventral hernias are a common, challenging, and expensive problem for both the general and reconstructive surgeons; therefore, the aim of this study is to critically assess perioperative factors related to cost in abdominal wall reconstructions (AWR). A retrospective review of AWR patients from 2007 and 2012 was performed. Analysis of perioperative factors associated with total cost of reconstruction was performed. Linear regression analyses were used to assess independent predictors of total cost. 134 consecutive AWR performed by a single surgeon over a 5-year period at an academic teaching center were included. The average total cost of AWR was $61,251 ± 55,624. Linear regression analysis demonstrated that diabetes (P = 0.026), increased American Society of Anesthesiologists score (P = 0.002), preoperative anemia (P = 0.001), and hernias derived from trauma (P = 0.015) were independently associated with added cost in AWR when controlling for confounding variables. In addition, patients requiring intra-abdominal procedures (P = 0.012) and those receiving an AWR using Acellular Dermal Matrix (P = 0.015) accrued significantly greater cost. Interestingly, preoperative placement of an epidural (P = 0.011) was independently associated with significant cost savings and reduced medical morbidity. Major surgical complications (P

Apert syndrome carries a characteristic phenotype of midface hypoplasia, syndactyly, craniosynostosis, and developmental delay. These patients frequently require a large number of surgical procedures to produce a functional and aesthetically pleasing correction of their facial deformities. Although most of the focus for surgical planning is allocated to the cranial vault and the midface, controversy exists as to whether the mandible is intrinsically abnormal in this population.A retrospective chart review was performed to identify patients with Apert syndrome cared for at The Children's Hospital of Philadelphia. Patients with available craniofacial computed tomographic scans after skeletal maturity were examined using cephalometric and three-dimensional volumetric techniques. A comparison was made to age- and demographically matched controls, and statistical significance was determined using the Student t test (P < 0.05).Thirty-eight patients, in total, were identified, 9 of which had available three-dimensional computed tomographic scans. Most patients underwent frontal-orbital advancement in their infancy and at least 1 midface procedure later in life. Three-dimensional volumetric analysis identified a decreased maxillary volume (P = 0.03) in the population with Apert syndrome but found no difference in the mandibular volume (P = 0.59). Cephalometric analysis demonstrated that the patients with Apert syndrome have normal ramal height but a statistically significant decreased mandibular length.The mandible with Apert syndrome seems to be intrinsically normal on the basis of our three-dimensional analysis, and differences in appreciated mandibular length are likely related to the interrelationship with the maxilla. Patients can therefore be instructed that improving the midface position may likely also reduce the compensatory mandibular deformity.

Posterior cranial vault distraction osteogenesis has replaced fronto-orbital advancement in some centers as the first-line treatment in patients with syndromic craniosynostosis. Despite this fact, little has been written about its craniometric effects on children with syndromic craniosynostosis.A retrospective review of all patients who underwent posterior distraction was performed. Patient demographic, perioperative data, and preoperative/postoperative computed tomographic scans were reviewed. Volumetric and craniometric indices were calculated and measured using commercial three-dimensional imaging software.From 2008 to 2012, 22 patients underwent posterior vault distraction osteogenesis for suspected intracranial hypertension or severe turribrachicephaly. In 13 patients, this was the first cranial vault procedure performed, whereas eight had previous fronto-orbital advancement and one had parieto-occipital reshaping. Half of patients underwent posterior cranial vault distraction osteogenesis before age 1 year; the average age at surgery was 2.3 years (range, 0.3 to 14.1 years) and distraction length averaged 27.3 mm (range, 19 to 35 mm). Average length of surgery was 2.9 hours (range, 1.6 to 3.8 hours), and average blood loss was 400 ml (range, 200 to 600 ml). Total treatment length was 91 days (range, 48 to 147 days). Distraction length averaged 27.3 mm (range, 19 to 35 mm). Intracranial volume increase averaged 21.5 percent (range, 7.5 to 70.0 percent; p0.0001) and 28.4 percent (range, 10.8 to 66.0 percent; p=0.01) in the subset of patients younger than 1 year. Posterior cranial height increased 12.2 percent (range, 0 to 35 percent; p=0.002), and basofrontal angle decrease averaged 3.9 percent (range, 0 to 12 percent; p=0.003), indicating a decrease in cranial height trajectory and improvement in frontal bossing.Posterior cranial vault distraction is a safe and effective operation that may lower risk of intracranial hypertension and abnormal skull morphology. Interestingly, cranial morphological benefits were seen both anteriorly and posteriorly.Therapeutic, IV.
