The fibula flap is the workhorse for mandibular reconstruction, but fibula bone width is not ideal to match mandibular height. In this study, in situ widening of the fibula with distraction osteogenesis before transfer is evaluated as a solution. The authors present a proof of concept of this technique with a patient series, including one patient who has undergone subsequent orthognathic surgery of the reconstructed mandible.A retrospective review of patients undergoing the authors' technique was performed. A longitudinal fibula osteotomy was made in situ and distraction was performed in the leg to widen the fibula. After distraction and consolidation periods, flaps were osteotomized and transferred to the mandible.This technique was applied to three patients (ages 9, 11, and 13 years) with Pruzansky III mandibular hypoplasia at the authors' institution over 15 years. In all cases, bony union was achieved. Mean surgical follow-up was 5 years. No significant morbidity occurred at the donor sites. Partial flap resorption was observed a number of years postoperatively in one patient. Temporomandibular joint ankylosis developed in one patient after closed treatment of an unrelated mandible fracture. A sinus tract developed in one patient, requiring débridement of a partial flap necrosis. One patient had orthognathic surgery, including osteotomy of the fibula.In situ fibula distraction osteogenesis is a novel technique to prelaminate a fibula flap before transfer to the mandible. This method allows for the reconstruction of challenging mandibular defects without compromising bone height, pedicle length, or the ability to perform orthognathic surgery.Therapeutic, IV.

Primary rhinoplasty (PR)at the time of cleft lip repair is controversial. We previously performed a systematic review that supported PR during unilateral cleft lip repair. We now aim to determine whether the same idea translates to care of patients with bilateral cleft lip.A systematic review was conducted adhering to Preferred Reporting Items for Systematic Reviews and Meta-analysis statement guidelines. PubMed and Embase databases were searched for studies that met our inclusion criteria: (1) English language, (2) human subjects, (3) rhinoplasty at the time of bilateral cleft lip repair, and (4) evaluation of nasal outcome. Studies were excluded in case of: (1) inclusion of a large proportion of syndromic patients, (2) case reports, (3) editorials, (4) letters, (5) reviews, and (6) exclusive to unilateral clefts. Out of 281 studies that showed up on initial search, 12 were included in our review. Research quality and level of evidence rating were determined for each study.Of the 12 included studies, 9 supported PR at the time of bilateral cleft lip repair; 8 studies evaluated nasal growth and found no restriction over time; 4 studies followed 158 patients to an average of 15 years and showed 77% did not need secondary rhinoplasty.Although the available literature supports PR in patients with bilateral cleft lip with respect to subjective and objective outcomes, nasal growth, and reducing the need for secondary/revision rhinoplasty, there are significant limitations, necessitating large volume studies.

Primary rhinoplasty (PR) during correction of unilateral cleft lip continues to be a topic of debate due to concerns that early nasal intervention affects nasal and maxillary development long-term. This study aims to determine the volume and quality of evidence for and against primary unilateral cleft rhinoplasty.A systematic review was performed adhering to the PRISMA Guidelines. Articles were pulled from PubMed and EMBASE and screened by title and abstract. Studies with human subjects undergoing rhinoplasty at the time of unilateral cleft lip repair and some evaluation of the nasal outcome were included. Studies with a large proportion of syndromic patients, case reports, editorials, letters, reviews, studies exclusive to bilateral clefts, and studies not available in English were excluded. Those that met criteria were then systematically reviewed.Twenty-five articles were included. Ten articles that assessed the results of PR subjectively all supported cleft lip repair with PR. Sixteen articles assessed the results of PR objectively, with fifteen supporting PR during cleft lip repair. Eight of nine studies that evaluated nasal growth and development over time found no restriction in nasal development. Five studies with a follow-up period of at least six years found the percentage of patients that avoided revision rhinoplasty ranged from 43% to 100%. There were significant risks of bias in a majority of studies.The vast majority studies reviewed support that primary rhinoplasty during unilateral cleft lip repair results in good outcomes with limited or no effect on nasal growth.

Objective: Treacher Collins syndrome (TCS) is a rare congenital craniofacial disorder with extensive associated eyelid deformities. Given its rarity and the breadth of manifestations, many treatment options have been previously described, but never summarized. Design: A literature review adherent to PRISMA guidelines and pertaining to surgical outcomes of TCS eyelid repair was performed. Successful surgical outcomes were defined as improvement or satisfaction as described by the authors. Results: A total of 144 patients and 212 procedures from 24 articles were included in this review. The mean age of first eyelid reconstruction was 13 years (range 1-36 years). Previous craniofacial surgery for malar insufficiency was performed in 57% of patients using a calvarial bone graft (n = 56), temporal osteomuscular flap (n = 21), split-rib graft (n = 3), and malar implant (n = 2). Patients underwent between 1 and 3 eyelid procedures (median 2). Most common eyelid defects included pseudocolobomas (54%), lateral canthal dystopia (38%), and true colobomas (8%). Coloboma repairs had the highest success rate (92%), followed by pseudocoloboma (80%), and lateral canthal dystopia repair (79%). Coloboma repair had the highest revision rate (13%), followed by pseudocoloboma repair (2%). Conclusion: TCS eyelid abnormalities most commonly present as pseudocolobomas, true colobomas, and lateral canthal dystopia. Given this diversity of presentations in TCS, surgical management must ultimately be tailored to the collective defects present with consideration of previous craniofacial reconstruction and current midface development.

Objective: Few studies have focused on perioperative management of cleft lip repair. We sought to evaluate the available data on this topic to create evidence-based clinical guidelines. Design: Systematic review, meta-analysis. Methods: A PubMed search was performed focusing on perioperative management of cleft lip repair. Studies were included if they included comparative data. A systematic review and meta-analysis was performed according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Main Outcome Measures: Systematic review of literature regarding wound closure, postoperative arm restraints, perioperative antibiotics, outpatient or ambulatory surgery, or feeding restrictions postoperatively. Results: Twenty-three articles met inclusion criteria after initial screening of 3103 articles. This included 8 articles on wound closure, 2 on postoperative restraints, one on perioperative antibiotics, 6 on outpatient surgery, and 6 on postoperative feeding. Meta-analysis could be performed on dehiscence rates with postoperative feeding regimen and readmission rates after outpatient versus inpatient lip repair. There were few studies with low risk of bias. Outpatient cleft lip repair does not increase readmission (odds ratio [OR]: 0.92, 95% CI: 0.28-3.07). Allowing postoperative breastfeeding or bottle-feeding does not increase dehiscence (OR: 0.61, 95% CI: 0.19-1.95). There was no evidence of publication bias. Conclusion: Within the limitations of available data, there is no evidence of a clearly superior closure material. The evidence does not support use of postoperative arm restraints. The evidence does not support the use of preoperative nasal swabs for antibiotic guidance. With careful patient selection, outpatient cleft lip repair appears safe. The evidence supports immediate breastfeeding or bottle-feeding after cleft lip repair.

The purpose of this study is to determine areas of agreement and disagreement among American Cleft Palate-Craniofacial Association (ACPA)members in the clinical practice of alveolar bone grafting (ABG), to guide further research to optimize ABG practices. A cross-sectional survey was conducted. The respondents were in an academic, combination, or private practice. The respondents were either plastic or oral and maxillofacial surgeons (OMFS) from various countries. A de-identified 24-question online survey was distributed to ACPA surgeon members utilizing the Research Electronic Data Capture (REDCap) tool. Data collected included surgeon specialty, use of various alveolar bone graft surgical techniques, as well as protocols. There was more variability than consensus between specialties with regards to the preoperative workup, timing of surgery, materials used for bone graft, surgical techniques, perioperative management, and postoperative evaluation. There was consensus on grafting during mixed dentition, not staging soft and hard tissue closure, and using iliac crest for primary and secondary grafting. Disagreements involved factors used to time the procedure and type of imaging used to assess viability. Technical differences involved incision type, part of bone grafted, use of minimally invasive technique, and material used for revisions. Aside from areas of consensus among surgeons on ABG, several areas, including use of bone substitutes in revision grafting, incision and type of iliac crest graft used during initial grafting, and postoperative protocols, had no consensus. These areas should be targets of further research to determine if there truly is an optimal method to perform ABG. The study was approved by the University of Illinois at Chicago Institutional Review Board. A de-identified 24-question online survey was distributed to surgeon members of the ACPA utilizing the REDCap tool on August 7, 2020. The survey questions consisted of multiple choice and multiple selection questions including an option to select “other” and specify the information in a blank space. Data collected included surgeon specialty, use of various alveolar bone graft surgical techniques, as well as pre and postoperative protocols. The full survey is included in online Supplemental material. Data analysis was performed in SPSS Statistics 27 (IBM Corp.). Descriptive statistics were performed, and chi-square was used to test for significant differences in survey responses between groups.

The cervicofacial flap is a workhorse flap for reconstruction of moderate to large sized defects of the cheek. Defects that involve the eyelid-cheek junction are often the most challenging of these. While the ideal plane of dissection has been debated, it is our belief that dissection in the sub-superficial musculo-aponeurotic system (SMAS) plane provides better aesthetic and functional outcomes due to enhanced vascularity, fascial support, and additional bulk of the flap itself. The authors present a series of 9 patients who presented with heterogeneous defects of the eyelid-cheek junction after cancer resection and underwent reconstruction using a sub-SMAS cervicofacial flap. At a mean follow-up time of 20 months, the cohort had 2 patients who developed lower lid retraction requiring revision and 2 other minor complications. This series lends support to the versatility and reliability of the sub-SMAS cervicofacial flap for large defects of the eyelid-cheek junction.

After studying this article and viewing the video, the participant should be able to: 1. Compare the relative stability and neurosensory changes following mandible distraction osteogenesis with those after traditional advancement and fixation. 2. Describe the condylar changes that can occur after mandible distraction osteogenesis and list three ways to mitigate these changes. 3. Propose clinical situations where segmental or rotational movements of the midface may allow improved outcomes compared to en bloc linear distraction advancement. 4. Summarize the advantages and risks associated with anterior and posterior cranial distraction osteogenesis compared to traditional one-stage expansion.Over the past 30 years, distraction forces have been applied to the spectrum of craniofacial osteotomies. It is now time to assess critically the current understanding of distraction in craniofacial surgery, identifying both traditional procedures it has replaced and those it has not. This article provides a review of comparative studies and expert opinion on the current state of craniofacial distraction compared with traditional operations. Through this critical evaluation, the reader will be able to identify when distraction techniques are appropriate, when traditional techniques are more favorable, and what the future of distraction osteogenesis is.

BACKGROUND Secondary fusion of initially patent cranial sutures after primary correction of nonsyndromic craniosynostosis is rarely reported. This study's aim is to report the incidence and analyze whether there are variables that may predispose to such fusion. METHODS A single-institution, retrospective, case-control study was conducted of all nonsyndromic patients who underwent operative treatment for craniosynostosis from April of 2008 to May of 2017. Patients with less than 1 year of follow-up and/or without a 1-year postoperative computed tomographic scan were excluded. Preoperative, intraoperative, and postoperative variables were analyzed using univariate and multivariate analyses. RESULTS Sixty-six patients were included in the study, with a mean 2.57-year postoperative follow-up. Six patients (8.8 percent) were found to have secondary craniosynostosis, all of whom had fusion of sutures that were initially patent and refusion of the primary pathologic suture(s). Fifty percent of secondary fusions presented as pansynostosis. On univariate analysis, suturectomy with barrel staving (p < 0.01) was significantly associated with secondary suture fusion. On multivariate analysis, bilambdoid suture involvement (p = 0.03) and suturectomy with barrel staving (p = 0.01) were significantly associated with secondary suture fusion. CONCLUSIONS Secondary cranial suture fusion may be a relatively common complication after primary craniosynostosis correction. Suturectomy with barrel staving was independently associated with secondary craniosynostosis. Wide surgical separation of the dura from the cranium and osteotomies across patent sutures may predispose to secondary craniosynostosis. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Background The COVID-19 pandemic necessitated masking in public spaces. Masks may impact the perceived attractiveness of individuals and hence, interpersonal relations. Objectives To determine if facial coverings affect attractiveness. Methods An online survey was conducted using 114 headshot images, 2 each—unmasked and masked—of 57 individuals. Two hundred and seven participants rated them on an ordinal scale from 1 (least attractive) to 10 (most attractive). Parametric and nonparametric tests were performed, as appropriate, for comparison. Results For the first quartile, the average rating increased significantly when wearing a mask (5.89 ± 0.29 and 6.54 ± 0.67; P = 0.01). For control images ranked within the fourth quartile, the average rating decreased significantly when wearing a mask (7.60 ± 0.26 and 6.62 ± 0.55; P < 0.001). In the female subgroup (n = 34), there was a small increase in average rating when masked, whereas in the male subgroup (n = 23), there was a small decrease in average rating when masked, but the change was not statistically significant (P > 0.05). For unmasked female images ranked within the first quartile, the average rating increased significantly when wearing a mask (5.77 ± 0.27 and 6.76 ± 0.36; P = 0.001). For the female subgroup with mean ratings within the fourth quartile, the average decreased significantly when wearing a medical mask (7.53 ± 0.30 and 6.77 ± 0.53; P < 0.05). For unmasked male images ranked within the first quartile, the average rating increased when wearing a medical mask but the change was not statistically significant (P > 0.05), whereas for the control male images within the fourth quartile, the average rating decreased significantly when masked (7.72 ± 0.18 and 6.50 ± 0.54; P < 0.05). Conclusions While wearing a facial covering significantly increased attractiveness for images less attractive at baseline, and decreased attractiveness for those that are more attractive at baseline; it did not cause a significant overall change in attractiveness in the study population.

BACKGROUND Lower eyelid defects are traditionally classified based on depth and 25 percent increments in defect width. The authors propose a new classification system that includes the vertical defect component to predict functional and aesthetic outcomes. METHODS A retrospective review of patients who underwent lower lid reconstruction performed by a single surgeon was performed. Defects were classified into four categories based on the vertical component: (1) pretarsal; (2) preseptal; (3) eyelid-cheek junction; and (4) complex pretarsal/preseptal. Preoperative and postoperative central and lateral marginal reflex distance-2 values were obtained. Aesthetic outcomes were evaluated by three blinded reviewers. Outcomes were compared using one-way analysis of variance and analysis of covariance with Bonferroni corrected post hoc comparisons to control for defect area and width. RESULTS Thirty-four patients underwent reconstruction of lower eyelid defects. There were 12 pretarsal defects (type I), nine preseptal defects (type II), nine eyelid-cheek defects (type III), and four complex pretarsal/preseptal defects (type IV). Postoperative retraction was highest in the complex pretarsal/preseptal group at 75 percent, with a significantly greater change from preoperative to postoperative central and lateral marginal reflex distance-2 compared with the other groups (p < 0.01) and worse postoperative mean aesthetic scores (p < 0.001). Type IV patients had significantly more revision operations (mean, 5.5) compared with the other groups (p < 0.001). CONCLUSIONS The vertical dimension of lower eyelid defects is an important variable. A new classification system is proposed that supplements width-based methods for improved surgical planning and prediction of postoperative outcomes in lower eyelid reconstruction.

Background Hidradenitis suppurativa (HS) severely impacts patients’ quality of life (QoL). Surgery has shown potential in improving a patient's QoL in severe disease. Previous studies have evaluated QoL after surgery, but lack a disease-specific questionnaire to better evaluate the unique burden of disease that patients with HS experience. Objective To measure postoperative QoL in patients with HS using a modified version of the disease-specific questionnaire, the Hidradenitis Suppurativa Burden of Disease (HSBOD) Tool. Methods A retrospective study was conducted using 19 patients who underwent surgery for HS. A demographic form and a 19-item disease-specific questionnaire were emailed to patients who consented to complete the survey. Patient-reported outcomes were recorded on a 0-100 scale (100 representing the highest burden of disease). Results Of the 24 patients that received the survey, 19 completed it in its entirety. The mean±SD Burden of Disease (BoD) score for each of the five domains assessed by the survey were: symptoms and feelings (62±27), daily activities (65±30), leisure (57±31), work and school (48±32), and personal relationships (56±27). Pearson’s correlation between the number of surgeries each patient underwent and their reported BoD scores were not significant. BoD scores were significantly higher in the symptoms and feelings domain for complex closure compared to both secondary intention and split-thickness skin grafting (STSG). Conclusion Despite having surgery, patients with hidradenitis still report impaired QoL. Further study is ongoing to determine how these measures compare to baseline preoperative values. This instrument provides a valuable tool to determine QoL in patients with hidradenitis.

Background The purpose of this study was to quantify change in cranioorbital morphology from presentation, after fronto-orbital advancement, and at 2-year follow-up. Methods Volumetric, linear, and angular analyses were performed on computed tomographic scans of consecutive bilateral coronal synostosis patients. Comparisons were made across three time points, between syndromic and nonsyndromic cases, and against normal controls. Significance was set at p Results Twenty-five patients were included: 11 were nonsyndromic, eight had Saethre-Chotzen syndrome, and six had Muenke syndrome. Total cranial volume was comparable to normal, age-matched control subjects before and 2 years after surgery despite an expansion during surgery. Axial and sagittal vector analyses showed advancement and widening of the lower forehead beyond control values with surgery and comparable anterior position, but increased width compared to controls at 2 years. Frontal bossing decreased with a drop in anterior cranial height and advanced lower forehead position. Middle vault height was not normalized and turricephaly persisted at follow-up. Posterior fossa volume remained lower at all three time points compared to control subjects. Supraorbital retrusion relative to anterior corneal position was overcorrected by surgery, with values comparable to those of control subjects at 2 years because of differential growth. There was no difference at 2 years between syndromic and nonsyndromic groups. Conclusions Open fronto-orbital advancement successfully remodels the anterior forehead but requires overcorrection to be comparable to normal at 2 years. Although there are differences in syndromic cases at presentation, they do not result in significant morphometric differences on follow-up. Posterior fossa volume remains lower at all time points.

Purpose Subcranial midface distraction is used to treat central midface deficiency in syndromic synostosis. Our aim was to determine which maxillary movements were associated with improvement in measures of obstructive sleep apnea. Methods This was a retrospective cohort study that reviewed patients with syndromic midface retrusion and documented sleep apnea who underwent subcranial midface distraction via either Le Fort 3 osteotomy or Le Fort 2 osteotomy with zygomatic repositioning. The predictor variables measured on cephalograms were the magnitude and direction of midface and mandibular movements. The primary outcome was the change in the apnea hypopnea index (AHI) from polysomnography before and after surgery. The secondary outcomes were volumes of upper airway containing bone spaces calculated from computed tomography scans. Data analysis included linear regression to estimate the effect of distraction vectors on bone space volumes and AHI changes. Results We included 18 patients primarily with Crouzon or Apert syndrome. The magnitude of distraction in a horizontal direction was the most significant factor for AHI improvement and primarily expanded the nasopharyngeal space, but with a smaller impact on the oral cavity space. Clockwise palate rotation was most influenced by a downward direction of distraction, with 24° below horizontal creating a neutral advancement. The greater the magnitude of advancement, the more likely a counterclockwise rotation was observed. Conclusions Horizontal magnitude of advancement had the greatest impact on AHI improvement. Vertical lengthening and closure of anterior open bite deformities can be done without compromising airway results as long as total advancement is not compromised. Palate rotation is best controlled by a downward distraction vector, but counterclockwise rotation increases with greater advancement.

The aim of the study was to determine if the additional surgical complexity of Lefort II distraction with zygomatic repositioning (LF2ZR) results in increased complications compared to Lefort III distraction (LF3). A retrospective review was performed of all LF3 and LF2ZR advancements performed by the senior author over 15 years. Demographic, operative, postoperative, and cephalometric data were collected from initial procedure through greater than 1 year postoperatively. Univariate and multivariate analyses were performed to compare procedures. 19 LF2ZR and 39 LF3 in 53 patients met inclusion criteria. Diagnoses differed between procedures, with more Crouzon Syndrome in LF3 and more Apert Syndrome in LF2ZR. Complication rate was 7/19 for LF2ZR and 12/39 for LF3 with no severe morbidity or mortality, and no difference between procedures (p = 0.56). The types of complications encountered differed between procedures. LF2ZR had a significantly longer operative time (506 ± 18 vs. 358 ± 24 min, p0.001). However, a greater number of LF2ZR patients underwent concomitant procedures (15/19 vs. 13/39, p0.001). Multivariate analysis revealed that Apert Syndrome and reoperative midface advancement were the most significant predictors of increased blood loss. LF2ZR has an equivalent complication rate to LF3. Therefore, it is our treatment of choice for cases requiring differential sagittal and vertical distraction of the central midface.

Airway management in neonates with Pierre Robin sequence (PRS) can be challenging. The goal was to describe the algorithm developed by the authors over the past 8 years.A retrospective case series analyzing airway management in neonates with PRS admitted to the neonatal intensive care unit at a tertiary care pediatric hospital was performed. The utility of the proposed algorithm for airway management incorporating more consistent use of polysomnography (PSG), and airway assessment was assessed.A total of 31 neonates with PRS (12 men, 19 women) with a mean gestational age of 38.2 weeks were analyzed. Thirteen (41.9%) patients had a named syndrome, chromosomal abnormality, or global delay. Twenty (64.5%) patients had pre-intervention PSG, and severe obstructive sleep apnea with an apnea-hypopnea index (AHI) ≥ 10 events/hour was identified in 19 (95.0%). Mandibular distraction osteogenesis was performed in 18 (58.1%) patients, and improved the AHI on post-operative PSGs. Direct assessment of the upper and lower airways was performed in 19 patients, and 13 (68.4%) were found to have secondary airway pathology. Presence of a concomitant syndrome was significantly associated with need for tracheostomy.The algorithm differs from previous ones in that it relies on rigorous pre- and post-intervention PSG (including with a nasopharyngeal airway), as well as that it allows flexibility between treatment options given the whole-patient clinical scenario and endoscopic findings. Results from these studies may be integrated to stratify patients into those who are most likely to benefit from conservative interventions or surgical procedures.

Objective:The concept of mandibular catch-up growth is often quoted in the literature regarding Pierre Robin sequence (PRS). We endeavored to perform a systematic review of whether the literature supports this concept.Design:Systematic review.Interventions:A PubMed-based systematic review of the English literature was performed of articles objectively measuring mandibular growth or position after nonoperative management of PRS.Main Outcome Measures:Rate and end point of mandibular length, ramus length, gonial angle, and maxillomandibular discrepancy.Results:The initial search delivered 607 English-language abstracts. Of these, 16 met inclusion criteria. Eight articles evaluating 143 patients followed longitudinal patient data and therefore allowed comparison of growth rates to controls. Ten articles evaluating 228 patients presented cross-sectional data and therefore could only evaluate a single time point. Two of the 8 longitudinal studies reported faster than normal growth of mandibular length in a significant portion of their cohort. Five of 8 reported equal growth rates. One of 16 studies reported that mandibular length of patients with PRS normalized compared to controls. Two of 16 studies reported no difference in maxillomandibular discrepancy between PRS and controls, whereas 10 reported a posteriorly displaced mandible relative to the maxilla in PRS. Significant differences in control groups, patients, and age existed between studies.Conclusions:While the concept of catch-up growth in PRS is often quoted, a minority of objective studies suggest increased mandibular growth rates in isolated PRS. Even fewer studies suggest that the maxillomandibular discrepancy in PRS completely resolves.

The creation of a neoumbilicus is a common challenge for plastic surgeons. The authors present their technique of umbilical reconstruction with bilateral square "pumpkin-teeth" advancement flaps. The technique described is applicable in both the setting of a vertical midline incision and when no midline incision is present (e.g., an abdominoplasty). The reconstruction has been performed in over 50 patients with a vertical midline incision and five patients without a midline incision. The only complications noted were persistent serous drainage in several patients with vertical incision and inadequate depth in one patient without a midline incision. This technique is quickly performed, and avoids small flaps, external incisions, and healing by secondary intention.

BACKGROUND The relative effects of skin growth and stretch during tissue expansion have not been studied. The authors use novel analytic techniques that allow calculation of these factors at any point of a skin patch. OBJECTIVE The authors sought to determine how stretch and growth change with different expansion rates and to correlate these values with histologic and cellular changes in skin. MATERIALS AND METHODS Two minipigs were implanted with a total of 5 tissue expanders under tattooed skin grids. One pig was expanded over 35 days and the second over 15 days. Isogeometric analysis allowed calculation of growth and stretch. Expanders with similar total deformation were compared between protocols. Regression analysis determined predictive effects of stretch and growth on histologic data from the second animal. RESULTS Deformation was more attributable to stretch in rapid than in slow expansion (1.40 vs1.12, p < .001). Growth was higher in slow expansion than in rapid (1.52 vs 1.07, p < .001). Both growth and stretch predicted epidermal thickness, dermal thinning, and keratinocyte proliferation. Growth predicted vascularity. CONCLUSION Isogeometric analysis allows determination of precise surface area changes for correlation to microscopic-level data. Using the model, the authors identified that skin deformation in rapid expansion is more attributable to stretch.

Summary Background Temporal hollowing is a common complication following surgical dissection in the temporal region. Our objectives were to: (1) review and clarify the temporal soft tissue relationships – supplemented by cadaveric dissection – to better understand surgical approach variations and elucidate potential etiologies of postoperative hollowing; (2) identify if there is any evidence to support a surgical approach that prevents hollowing through a systematic review. Methods Cadaveric dissection was performed on six hemi-heads. A systematic review of the literature was undertaken to identify surgical approaches with a decreased risk of postoperative hollowing. Results A total of 1212 articles were reviewed; 19 of these met final inclusion criteria. Level I and II evidence supports against the use of a dissection plane beneath the superficial layer of the deep temporal fascia or through the intermediate temporal fat pad. Level II evidence supports preservation of the temporalis muscle origin – no evidence is available to support other temporalis resuspension techniques. For intracranial exposure, refraining from temporal fat pad dissection (Level I Evidence) and use of decreased access approaches such as the minipterional craniotomy (Level I Evidence) appear to minimize temporal soft tissue atrophy. Conclusions This study highlights the significance of preservation of the temporal soft tissue components to prevent hollowing. Preserving the temporalis origin and avoiding dissection between the leaflets of the deep temporal fascia or through the intermediate temporal fat pad appear to minimize this complication.

Orbital fractures are common. In patients where there is significant loss of the medial wall and orbital floor, anatomic prebent 3-dimensional plates allow efficacious restoration of orbital volume. However, the large size of these plates can result in technical difficulties with plate placement, especially in fractures with complete loss of 2 walls of the orbit. In this article, the authors review the pertinent anatomy of the bony orbit with respect to fracture and landmarks in fracture reduction. The authors also note the 3 most commonly encountered problems with the placement of anatomic plates: poor exposure, failure to identify the posterior ledge for the plate, and rotational issues with plate placement resulting in impingement. Technical tips are given to help overcome these issues intraoperatively.

BACKGROUND The present study examined risk factors associated with 30-day palatoplasty complications based on analysis of national data. METHODS Primary palatoplasties were identified in the 2012 to 2015 Pediatric National Surgical Quality Improvement Program database. Cases were analyzed with multivariate regression to investigate predictors for wound healing complications, additional ventilation requirement, prolonged stay (>3 days), and readmission. RESULTS In 3616 operations, mean age was 12.2 months and operative time was 135.4 minutes. The 30-day complication rate was 7.6 percent overall, including wound dehiscence/infection (3.4 percent), additional ventilation requirement (2.0 percent), and readmission (2.4 percent); 5.1 percent of patients required prolonged stays. Wound healing complications were not predicted by comorbidities. American Society of Anesthesiologists class 3 or greater (OR, 2.8; p = 0.033), neuromuscular disorder (OR, 3.5; p = 0.029), and nutritional support (OR, 2.9; p = 0.035) predicted additional ventilation requirement. Prolonged stays were predicted by requiring additional ventilation (OR, 14.7; p < 0.001) or American Society of Anesthesiologists class 3 or greater (OR, 1.8; p = 0.047), but preoperative ventilator dependence was protective (OR, 0.1; p = 0.012). Mean hospital stay was 1.6 days without an airway complication versus 5.0 days with. Readmissions were increased for patients requiring nutritional support (OR, 2.6; p = 0.025). CONCLUSIONS This study represents one of the largest cohorts of palatoplasty patients analyzed to date. It identifies what can be learned from a nonspecific 30-day registry regarding cleft outcomes and, from its limitations, discusses what the future of cleft outcomes research might entail.

OBJECTIVEUp to 10% of midline nasal dermoid cysts have intracranial extension. Previous techniques of excision include frontal and frontonasal craniotomies via a coronal approach, combined with a direct cutaneous excision of the dermoid cyst. While the coronal incision allows for wide visualization, it carries significant risks of transfusion, blood loss, and scarring. The authors present an alternative technique in which access is gained through a midline extension of the dermoid cyst excision that provides direct access for a keyhole frontal craniotomy.METHODSThe authors utilize a nasal bone osteotomy, pericranial flap, and keyhole-type craniotomy performed through a nasal midline incision for the treatment of nasal dermoid cysts with intracranial extension. They performed a retrospective chart review of all patients with nasal dermoid cysts treated at the Ann & Robert H. Lurie Children’s Hospital of Chicago from 2009 to 2017. Patient demographic data, operative data, and in- and outpatient complication data were collected.RESULTSIn 10 patients with cyst extension near or into the intracranial cavity (7 with true intracranial extension), the nasal osteotomy technique was performed. The mean blood loss was 13 ml, with a 0% transfusion rate. The mean length of inpatient stay was 1 day. A durotomy was made and repaired as part of the dermoid cyst dissection in 3 patients. One patient underwent intraoperative placement of a lumbar drain. The mean operative time was 228 minutes. There were no intraoperative or postoperative complications, including the need for a reoperation. No patients had any long-term complications, and no patients have had dermoid cyst recurrence. The appearance of the scar was acceptable in all cases.CONCLUSIONSThe midline approach to nasal dermoid cysts with intracranial extension is safe and results in limited blood loss, short operative times, and short lengths of inpatient hospital stay. This is a viable technique for the treatment of this challenging pathology.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare benign osseous tumor, usually presenting in the midface. There are many similarities in location, presentation, and radiographic appearance between fibrous dysplasia (FD) and JPOF. Awareness of this entity is important for craniofacial surgeons, as surgical timing and intraoperative management differ between these tumors. Findings that should raise suspicion of JPOF preoperatively include rapid growth, a shell of cortical bone surrounding the lesion, and clearly demarcated borders of the lesion on imaging, as opposed to a gradual transition between normal and abnormal bone. Definitive excision is the treatment of choice, and earlier surgery may provide better results by addressing the lesion at the smallest size possible. In contrast to FD, JPOF is not known to “burn out,” so there is minimal benefit to be gained from delay. We present a summary of the evidence for diagnosis and treatment of JPOF as well our experience with JPOF in an 11-year-old female who was initially diagnosed with FD. We aim to draw attention to the similar presentations of these entities so the reader will be able to more accurately manage these patients.

Background Of the minimally invasive “keyhole” alternatives to the pterional region, the supraorbital eyebrow approach is the most widely adopted. Yet it can prove disadvantageous when a more direct lateral microsurgical trajectory of attack to the Sylvian fissure and anterior middle fossa are needed. Objective The extended lateral orbital (XLO) approach was designed to be direct and minimally invasive, with the sphenoid ridge at the center of exposure. Methods Five injected cadaver heads were used for anatomic study of the XLO approach. The anatomic course of the frontalis branch of facial nerve was studied in relation to the XLO incision. Following XLO incision, the bone exposure was measured. The intracranial microsurgical exposure was assessed subjectively. Application of the technique in representative clinical operative cases is provided. Results The frontalis nerve was protected in the subgaleal fat pad, with an average minimum distance of 2.3 cm from the XLO incision. The mean calvarial area exposure was 4.95 cm2 and consistently centered on the sphenoid ridge. Excellent access to ipsilateral Sylvian's fissure, perisylvian regions, and supra-/parasellar structures was possible. The main limitations related to exposure of the posterior Sylvian fissure and the expected limitations of microsurgical instrument manipulation from a smaller craniotomy. Conclusions The XLO approach is a minimally invasive keyhole approach to the pterional region that affords a unique lateral trajectory via a craniotomy centered on the sphenoid ridge. Excellent exposure to properly selected lesions is possible. The incision is at a safe distance from the frontalis branch and shows excellent cosmetic healing.

Cleft lip represents one of the most common birth defects in the world. Although the timing of cleft lip repair is contingent on a number of factors, the "rule of 10s" remains a frequently quoted safety benchmark. Initially reported by Wilhelmsen and Musgrave in 1966 and modified by Millard in 1976, this rule referred to performing surgery once patients had reached cutoffs in weight, hemoglobin, and age/leukocyte count. Despite significant advances in both surgical and anesthetic technique, the oft-quoted "rule of 10s" has not been systematically investigated since its inception.Patients who underwent primary cleft lip repair were identified from the National Surgical Quality Improvement Program Pediatric database. Multivariate logistic regression models were used to determine the independent effect of each rule of 10 metric or violation of the rule of 10s as a whole on postoperative complications, and to determine independent risk factors for complications in cleft lip surgery.One thousand three hundred thirteen patients met inclusion criteria, with a 3.6 percent complication rate. Of the included patients, 151 (11.5 percent) violated at least one facet of the rule of 10s. Other than patient weight, neither the rule of 10s nor any individual metric was significantly predictive of postoperative complications.Since its introduction nearly a half century ago, the risks associated with performing surgery in patients who violate the rule of 10s has undergone dramatic reductions. This analysis highlights the need to continually validate and evaluate dogma as the field continues to advance.Risk, III.

Although there is a high incidence of flank defects after lateral abdominal access, there is a paucity of large studies discussing this problem. Most studies express nihilism regarding their surgical management. The goal of this study was to describe the authors' conceptualization of flank defects, with a determination of the number of true hernias versus bulges, and outcomes of surgical repair in these patients.The authors carried out a 13-year retrospective review of 31 consecutive flank defects repaired by the senior author (G.A.D.). Patients were treated with a 7.5-cm-wide macroporous polypropylene mesh and reapproximation of the abdominal wall to achieve a direct supported repair. There were 19 intraperitoneal placements and 12 placements between the external and internal oblique muscles or preperitoneal space. The prevalence of true hernia versus bulge at the time of repair was noted.There were no surgical-site infections. Two patients developed minor bulges at the prior hernia site: one of these was repaired with additional mesh, and the other one was observed. One small asymptomatic recurrent hernia was noted incidentally on a follow-up computed tomographic scan. Initially, 10 patients had a complete hernia through all layers of the lateral abdominal musculature, 17 patients had dehiscence of the internal oblique and transversus abdominis muscles with an intact external oblique muscle, and four patients had denervation with all layers of the abdominal wall intact.Most flank defects represent true hernias rather than denervation injuries. Direct supported repair of flank hernias using mesh is a safe and effective technique.Therapeutic, IV.

INTRODUCTION Whereas free tissue transfer has evolved to minimize morbidity in adults, less is known about outcomes after free flaps in children. This study sought to assess short- and long-term outcomes after microvascular reconstruction in the pediatric population. METHODS Short- and long-term outcomes of free tissue transfer were assessed using chart-review and quality-of-life surveys. The Pediatric Outcomes Data Collection Instrument was used to evaluate overall health, pain, and ability to participate in normal daily and more vigorous activities. Patient or parent responses were compared against normative data. RESULTS Forty-two patients underwent 48 flap reconstructions at a mean age of 8 years. Median follow-up was 14.9 years. Indications included congenital nevi (n = 19, 42%), lymphatic/vascular malformations (n = 8, 19%), and trauma/burns (n = 6, 14%). There were 21 fasciocutaneous (44%), 19 muscle/myocutaneous (40%), 6 fascial/peritoneal (13%), and 2 osteocutaneous flaps (4%). Major flap complications were observed in 4 patients (9%), whereas major donor-site complications occurred in 2% (1 patient). Valid contact information was available for 25 patients; 16 of these completed surveys (64%). Pediatric Outcomes Data Collection Instrument scores for mobility (median, 52), sports/physical functioning (median, 56), happiness (median, 50), and pain/comfort (median, 56) were not significantly different from normative population score of 50. Similarly, median global functioning score was 99 (maximum, 100) and did not differ between flap types. DISCUSSION Free tissue transfer in the pediatric population is reliable and well-tolerated over time. Surgeons should not hesitate to use free flaps when clinically indicated for pediatric patients.
