Aim: To evaluate the relationship between the surgical techniques, the waiting time for surgery, postoperative distance between the graft-bone margin and the percentage of bone resorption, we analyzed patients who underwent cranioplasty. Cranioplasty is a necessary surgery to preserve brain tissue and provide an appropriate microenvironment., Material and Methods: In this study, patients who underwent autologous bone grafting after decompressive craniectomy by the Neurosurgery Clinic of University of Health Sciences Ankara Training and Research Hospital between 2018 and 2021 were examined., Results: Thirty-nine patients who underwent autologous cranioplasty following decompressive craniectomy were included in the study. The average expected time for cranioplasty surgery following decompressive craniectomy was 16.97±13.478 weeks (min:2 max:62 weeks). The expected time between decompressive craniectomy and cranioplasty surgeries and resorption rates were compared. The resorption rate was above 30% in 7 of 10 patients with 24 weeks or more between craniectomy and cranioplasty, and less than 30% in 17 of 25 patients in surgeries less than 24 weeks (p=0.04). Following cranioplasty surgery, the distance between the graft-bone margin and the resorption rates were also compared. In this analysis, statistically significant differences were detected between the distance between the graft-bone border and the resorption rates. Resorption rates increased in 15 of 19 patients with a postcranioplasty distance of 1 mm or more (p < 0.00001)., Conclusion: Early cranioplasty surgery is important in order to reduce complications that may occur after craniectomy. In addition, it is important to keep the defect area small in size during craniectomy surgery and to keep the cutting edge thinner when the bone graft is taken, in order to reduce the development of bone graft resorption.

Background: Increasing number of patients are being operated because of breast cancer. Seroma is the most common problem that occurs after surgery that increases morbidity. For postoperative pain management, Thoracic Paravertebral Block (TPVB) has long been considered the gold standard technique. With performing TPVB, sympathetic nerves are also blocked., Objective: With this study, we aimed to search the effect of TPVB on seroma reduction in patients who undergo mastectomy and axillary node dissection surgery., Methods: Forty ASA I-II female patients aged 18-65, who were scheduled to go under elective unilateral mastectomy and axillary lymph node resection were included to the study. Patients were randomized into two groups as TPVB and control group. Ultrasound guided TPVB with 20 mL 0.25% bupivacaine was performed at T1 level preoperatively to the TPVB group patients. All patients were provided with i.v. patient-controlled analgesia device. Seroma formation amounts, morphine consumptions and Numeric Rating Scale (NRS) scores for pain were recorded 24 th hour postoperatively., Results and Conclusions: Mean seroma formation at postoperative 24 th hour was 112.5±53.3 mL in the control group and 74.5±47.4 mL in the TPVB group (p=0.022). NRS scores were similar between two groups (p=0.367) at postoperative 24 th hour but mean morphine consumption at postoperative 24 th hour was 5.6±4 mg in the TPBV group, and 16.6±6.9 mg in the control group (p <0.001). TPVB reduces the amount of seroma formation while providing effective analgesia in patients who undergo mastectomy and axillary lymph node removal surgery., (Copyright © 2020 Sociedade Brasileira de Anestesiologia.

Purpose: Reconstruction of the lateral collateral ligament (LCL) and biceps femoris tendon following proximal fibula resection is controversial. Postoperative knee instability and peroneal nerve dysfunction affect outcome. This study aimed to determine functional, clinical, and radiological outcomes of patients who underwent en bloc proximal fibula resections and to compare clinical and radiological instability rates for primary repair after type I and type II resections., Materials and Methods: Eleven patients with primary tumors of the proximal fibula were included. Musculoskeletal Tumor Society (MSTS) score and Lysholm knee score were used in the evaluation of functional outcomes. Clinical outcome was assessed using knee range of motion and knee varus stress test. Radiological outcome was assessed using varus stress knee radiographs. Knee stability was evaluated using the varus stress test at 30° of knee flexion and varus stress knee radiographs and graded in millimeters., Results: Of the 11 tumors, 6 (54.6%) underwent type I resection. In five (45.4%) patients, type II resection was performed. The mean follow-up period was 32 ± 13.9 months (range, 12-55 months; median, 27 months). The mean knee joint lateral opening, MSTS score, and Lysholm knee score with type I versus type II resection were 5.7 ± 1.2 mm versus 6.4 ± 1.1 mm ( p = 0.247), 28.7 ± 1.8 (95.6%) versus 20.4 ± 7.7 (68%) ( p = 0.011), and 92.2 ± 8.8 versus 62.8 ± 20.4 ( p = 0.026), respectively. Postoperative complications of all patients included one (9.1%) deep tissue infection and one (9.1%) long-term knee instability. In one patient (9.1%) who underwent type II resection, above-the-knee amputation was performed after local recurrence., Conclusions: Primary repair of the LCL and biceps femoris tendon to the surrounding soft tissues after resection of proximal fibular tumors provides good clinical outcomes. Primary repair is a simple technique to perform with minimal morbidity. Peroneal nerve palsy was a problem, especially in type II resections. Level of Evidence: Therapeutic Level III.

Objective: To assess the nasal functions, nasal resistance, olfactory function, and quality of life in different surgical techniques for nasal septum deviation STUDY DESIGN:: Randomized controlled trial., Methods: This prospective controlled study was carried out on patients who underwent septoplasty. Patients participating in the study were divided into 2 groups; group 1: classic septoplasty (n: 25) and group 2: extracorporeal septoplasty (n: 14). The sinonasal outcome test-22 (SNOT-22), peak nasal flowmetry, and Connecticut Chemosensory Clinical Research Center test were applied to all patients before and 8 weeks after surgery. Surgical outcomes also assessed to evaluate complications 6 months after surgery., Result: In total, 39 (27 males, 12 females) patients diagnosed with nasal septum deviation were included in this study. A septoplasty was performed in all patients: 25 of them (18 males, 7 females; mean age = 29.4 [range, 23-50] years) underwent classic septoplasties and 14 (9 males, 5 females; mean age = 31.3 [range, 23-50] years) underwent extracorporeal septoplasties. Airway openness was achieved in all patients. As a result, the SNOT-22 scores, peak nasal inspiratory flowmeter results, and smell function scores showed significant improvements (P < 0.001)., Conclusion: All corrective surgical methods for a septum deviation have positive effects on nasal airflow, quality of life, and olfaction. The rates of complications were not significantly different between 2 treatment groups.

Background: Epidermoid cyst is a benign tumor that can occur anywhere in the body but is rarely seen in the penis. Congenital and previous penile surgeries have been reported to be involved in the etiology of the disease, which is usually asymptomatic. Here we describe a case of a patient with a penile epidermoid cyst, which occurred in the circumcision line on the left side of his penis, and urethral dehiscence following hypospadias surgery. A 3-year-old white boy who underwent primary distal hypospadias surgery 1.5 years ago presented with a slowly growing mass in the left ventrolateral portion of the penile circumcision line and urethral dehiscence. The histology of the excised mass revealed an epidermal inclusion cyst. Since then, he has remained healthy., Conclusions: Epidermal inclusion cyst as a complication of hypospadias surgery is a very rare situation. The diagnosis is made histologically and surgical excision is sufficient for treatment.

Objectives: The aim of the present study was to determine the radiological and functional results and the efficiency of paediatric radial neck fracture fixation following reduction with the Métaizeau technique together with percutaneous K-wire applied under fluoroscopy to ensure minimum soft tissue damage., Methods: The study included 20 patients with Judet Type 3, Type 4a and Type 4b fractures operated on with the Métaizeau technique aided by percutaneous K-wire between 2007 and 2014. The mean age of the patients was 9.75 years (range, 4-13 years). Mean preoperative angulation was measured as 52.4° (range, 35°-85°). The average postoperative follow-up time was 34.65 months (range, 13-84) months. Postoperative radiological evaluations were made according to the Ursei classification and functional assessment with the Tibone - Stoltz classification system., Results: Radiologically, the difference between preoperative and postoperative radius head angulation was found statistically significant (p0.001). In the clinical assessment of injured and uninjured arms, there was no statistically significant difference between flexion-extension (p = 0.330) and supination-pronation range of motion (p = 0.330) and carrying angles (p = 0.094). According to the radiological Ursei evaluation, 17 (85%) patients were in perfect condition and 3 (15%) were good. In the classification of Tibone - Stoltz, 16 (80%) patients were evaluated as perfect, 3 (15%) as good and 1 (5%) as fair., Conclusion: From the results of this study and related literature, the use of the Métaizeau technique in displaced radial neck fractures requiring surgical treatment in children can be recommended since it creates minimum damage to the soft tissue, is easy to apply and the results are satisfactory., Level of Evidence: Level IV, therapeutic study., (Copyright © 2018 Turkish Association of Orthopaedics and Traumatology.

Background Context: Pelvic tilt (PT) is used as an indicator of pelvic version with increased values indicating retroversion and disability. The concept of using PT solely as an absolute numerical value can be misleading, especially for the patients with pelvic incidence (PI) values near the upper and lower normal limits. Relative pelvic version (RPV) is a PI-based individualized measure of the pelvic version. Relative pelvic version indicates the individualized spatial orientation of the pelvis relative to the ideal sacral slope as defined by the magnitude of PI., Purpose: The aim of this study was to compare RPV and PT for their ability to predict mechanical complications and their correlations with health-related quality of Life (HRQoL) scores., Study Design: A retrospective analysis of a prospectively collected data of adult spinal deformity patients was carried out. Mechanical complications (proximal junctional kyphosis or proximal junctional failure, distal junctional kyphosis or distal junctional failure, rod breakage, and implant-related complications) and HRQoL scores (Oswestry Disability Index [ODI], Core Outcome Measures Index [COMI], Short Form-36 Physical Component Summary [SF-36 PCS], and Scoliosis Research Society 22 Spinal Deformity Questionnaire [SRS-22]) were used as outcome measures., Methods: Inclusion criteria were ≥4 levels fusion, and ≥2-year follow-up. Correlations between PT, RPV, PI, and HRQoL were analyzed using Pearson correlation coefficient. Pelvic incidence values and mechanical complication rates in RPV subgroups for each PT category were compared using one-way analysis of variance, Student t test, and chi-squared tests. Predictive models for mechanical complications with RPV and PT were analyzed using binomial logistic regressions., Results: A total of 222 patients (168 women, 54 men) met the inclusion criteria. Mean age was 52.2±19.3 (18-84) years. Mean follow-up was 28.8±8.2 (24-62) months. There was a significant correlation between PT and PI (r=0.613, p<.001), threatening the use of PT to quantify pelvic version for different PI values. Relative pelvic version was not correlated with PI (r=-0.108, p>.05), being able to quantify pelvic version for all PI values. Compared with PT, RPV had stronger partial correlations with ODI, COMI, SF-36 PCS, and SRS-22 scores (p<.05). Discrimination performance assessed by area under the curve, percentage accuracy in classification, true positive rate, true negative rate, and positive and negative predictive values was better for the model with RPV than for PT. For average PI sizes, the agreement between RPV and PT were moderate (0.609, p<.001), whereas the agreement in small and large PI sizes were poor (0.189, p>.05; -0.098, p>.496, respectively). When analyzed by RPV, each PT "0," "+," and "++" category was further divided into two or three distinct subgroups of patients having different PI values (p=.000, p=.000, and p=.029, respectively). Relative pelvic version subgroups within the same PT category displayed different mechanical complication rates (p=.000, p=.020, and p=.019, respectively)., Conclusions: Pelvic tilt may be insufficient or misleading in quantifying normoversion for the whole spectrum of PI values when used as an absolute numeric value in conjunction with previously reported population-based average thresholds of 20 and 30 degrees. Relative pelvic version offers an individualized quantification of ante-, normo-, and retroversion for all PI sizes. Schwab PT groups were found to constitute inhomogeneous subgroup of patients with different mean PI values and mechanical complication rates. Compared with PT, RPV showed a greater association with both mechanical complications and HRQoL., (Copyright © 2018 Elsevier Inc. All rights reserved.)

OBJECTIVE The subtraction of lumbar lordosis (LL) from the pelvic incidence (PI) offers an estimate of the LL required for a given PI value. Relative LL (RLL) and the lordosis distribution index (LDI) are PI-based individualized measures. RLL quantifies the magnitude of lordosis relative to the ideal lordosis as defined by the magnitude of PI. LDI defines the magnitude of lower arc lordosis in proportion to total lordosis. The aim of this study was to compare RLL and PI - LL for their ability to predict postoperative complications and their correlations with health-related quality of life (HRQOL) scores. METHODS Inclusion criteria were ≥ 4 levels of fusion and ≥ 2 years of follow-up. Mechanical complications were proximal junctional kyphosis/proximal junctional failure, distal junctional kyphosis/distal junctional failure, rod breakage, and implant-related complications. Correlations between PI - LL, RLL, PI, and HRQOL were analyzed using the Pearson correlation coefficient. Mechanical complication rates in PI - LL, RLL, LDI, RLL, and LDI interpreted together, and RLL subgroups for each PI - LL category were compared using chi-square tests and the exact test. Predictive models for mechanical complications with RLL and PI - LL were analyzed using binomial logistic regressions. RESULTS Two hundred twenty-two patients (168 women, 54 men) were included. The mean age was 52.2 ± 19.3 years (range 18-84 years). The mean follow-up was 28.8 ± 8.2 months (range 24-62 months). There was a significant correlation between PI - LL and PI (r = 0.441, p < 0.001), threatening the use of PI - LL to quantify spinopelvic mismatch for different PI values. RLL was not correlated with PI (r = -0.093, p > 0.05); therefore, it was able to quantify divergence from ideal lordosis for all PI values. Compared with PI - LL, RLL had stronger correlations with HRQOL scores (p < 0.05). Discrimination performance was better for the model with RLL than for PI - LL. The agreement between RLL and PI - LL was high (κ = 0.943, p < 0.001), moderate (κ = 0.455, p < 0.001), and poor (κ = -0.154, p = 0.343), respectively, for large, average, and small PI sizes. When analyzed by RLL, each PI - LL category was further divided into distinct groups of patients who had different mechanical complication rates (p < 0.001). CONCLUSIONS Using the formula of PI - LL may be insufficient to quantify normolordosis for the whole spectrum of PI values when applied as an absolute numeric value in conjunction with previously reported population-based average thresholds of 10° and 20°. Schwab PI - LL groups were found to constitute an inhomogeneous group of patients. RLL offers an individualized quantification of LL for all PI sizes. Compared with PI - LL, RLL showed a greater association with both mechanical complications and HRQOL. The use of RLL and LDI together, instead of PI - LL, for surgical planning may result in lower mechanical complication rates and better long-term HRQOL.

Background: The restoration of normal sagittal alignment is a critical goal in adult spinal deformity surgery to achieve favorable outcomes and prevent mechanical complications. Schwab sagittal modifiers have been accepted as targets for appropriate alignment, but addressing these targets does not always prevent high mechanical complication or revision rates. This may be because the linear absolute numerical parameters do not cover the whole pelvic incidence spectrum and the distribution of lordosis, pelvic anteversion, and negative malalignment are not considered as potential causes of failure. The aim of the present study was to develop and validate a score based on pelvic-incidence-based proportional parameters to better predict mechanical complications., Methods: Two hundred and twenty-two patients (168 women and 54 men) followed for ≥2 years after posterior fusion at ≥4 levels were included in the study. The mean age (and standard deviation) was 52.2 ± 19.3 years (range, 18 to 84 years), and the mean duration of follow-up was 28.8 ± 8.2 months (range, 24 to 62 months). The global alignment and proportion (GAP) score was developed and validated in groups of patients randomly assigned to derivation (n = 148, 66.7%) and validation (n = 74, 33.3%) cohorts. GAP score parameters were relative pelvic version (the measured minus the ideal sacral slope), relative lumbar lordosis (the measured minus the ideal lumbar lordosis), lordosis distribution index (the L4-S1 lordosis divided by the L1-S1 lordosis multiplied by 100), relative spinopelvic alignment (the measured minus the ideal global tilt), and an age factor. Proximal and distal junctional kyphosis and/or failure, rod breakage, and other implant-related complications were considered mechanical complications. The predictive accuracy of the GAP score was analyzed using receiver operating characteristic (ROC) analyses. Associations between GAP categories and mechanical complications and revisions were analyzed using Cochran-Armitage tests., Results: In the validation cohort, 32 patients (43%) experienced mechanical complications and 17 (23%) underwent mechanical revision. The area under curve for the GAP score predicting mechanical complications was 0.92 (standard error [SE] = 0.034, p < 0.001, 95% [confidence interval [CI] = 0.85 to 0.98). Postoperatively, patients with a proportioned spinopelvic state according to the GAP score had a mechanical complication rate of 6% while those with a moderately or severely disproportioned spinopelvic state had rates of 47% and 95%, respectively., Conclusions: The GAP score is a new pelvic-incidence-based proportional method of analyzing the sagittal plane that predicts mechanical complications in patients undergoing surgery for adult spinal deformity. Setting surgical goals according to the GAP score may decrease the prevalence of mechanical complications.

Objective: To report perioperative complications in fully endoscopic lumbar discectomy (FELD)., Methods: From September 2010 to November 2016, 835 patients underwent FELD. In total, 865 disc levels were operated on. Of the 835 patients, the transforaminal (TF) approach was used in 174 patients, while 691 patients were operated on using the interlaminar (IL) approach. Surgical complications occurred in 47 patients, which were retrospectively analyzed., Results: Neurological deficits occurred in six patients. In four of these six patients, deficits resolved spontaneously. In one patient, symptoms resolved after a laminectomy procedure. In only one case, the neurological deficit was permanent. Seven patients complained of dysesthesia, which resolved spontaneously with medical treatment in four patients. In the remaining two patients, dysesthesia symptoms improved after epidural and foraminal injections. Dural tears were encountered in 26 patients. Pudendal neuralgia occurred in three patients. Two cases showed wound infection. The other complications comprised one disc infection, one retroperitoneal hematoma and one wrong level surgery., Conclusion: The FELD procedure has a steep learning curve and it is a difficult procedure to master. Surgeons should be aware of complications that can occur with the FELD procedure, most of which resolve spontaneously., (Copyright © 2017 Sociedad Española de Neurocirugía.

Objective: The aim of this study was to analyze the impact of treatment complications on outcomes in adult spinal deformity (ASD) using a decision analysis (DA) model., Methods: The study included 535 ASD patients (371 with non-surgical (NS) and 164 with surgical (S) treatment) from an international multicentre database of ASD patients. DA was structured in two main steps; 1) Baseline analysis (Assessing the probabilities of outcomes, Assessing the values of preference -utilities-, Combining information on probability and utility and assigning the quality adjusted life expectancy (QALE) for each treatment) and 2) Sensitivity analysis. Complications were analyzed as life threatening (LT) and nonlife threatening (NLT) and their probabilities were calculated from the database as well as a thorough literature review. Outcomes were analyzed as improvement, no change and deterioration. Death/complete paralysis was considered as a separate category., Results: All 535 patients were analyzed in regard to complications. Overall, there were 78 NLT and 12 LT complications and 3 death/paralysis. Surgical treatment offered significantly higher chances of clinical improvement but also was significantly more prone to complications (31.7% vs. 11.1%, p < 0.001)., Conclusion: Surgical treatment of ASD is more likely to cause complications compared to NS treatment. On the other hand, surgery has been shown to provide a higher likelihood of improvement in HRQoL scores. So, the decision on the type of treatment in ASD needs to take both chances of improvement and burden associated with S or NS treatments and better be arrived by the active participation of patients and physicians equipped with the present information., Level of Evidence: Level II, Decision analysis., (Copyright © 2017 Turkish Association of Orthopaedics and Traumatology.

Aim: To compare the clinical results of different transcortical approaches for the removal of third ventricular colloid cysts (CC)., Material and Methods: Records of 41 colloid cyst patients who underwent transcortical conventional microsurgical, microsurgical with the aid of stereotactically guided cylindrical retractor (minitubular), and endoscopic removal between 1999 and 2015 were retrospectively analyzed. The clinical results of these three different transcortical surgical approaches were compared and a literature review of published series was conducted., Results: Ages ranged between 16 and 66 years (mean: 36.8). There were 18 female and 23 male patients. Headache was the main presenting symptom. The mean CC diameter was 15.5 mm. Intraventricular hemorrhage was encountered in 2 patients. Three patients needed postoperative ventriculoperitoneal shunt surgery. Postoperative seizures were seen in 3, postoperative neurological deficit in 3 and residual tumor in 2 patients. The conventional approach resulted in significantly higher rates of postoperative seizure compared to the minitubular and endoscopic approaches (p=0.012). The rate of residual cyst was significantly higher in endoscopic approach compared to conventional and minitubular approaches (p=0.024). Conventional approach led to significantly higher rates of neurological deficit compared to the two other approaches (p < 0.05)., Conclusion: With respect to complication rates, the stereotactic and endoscopic approaches are both safe and reliable compared to conventional microsurgical approach that has unacceptably high rates of seizures and neurological deficit. Concerning completeness of removal, both microsurgical approaches are by far superior to neuroendoscopy. The stereotactic microsurgical approach compares favorably in both respects with endoscopic and conventional microsurgical approaches.

We conducted a cross-sectional study to assess vocal and swallowing functions after horizontal glottectomy. Our study population was made up of 22 men aged 45 to 72 years (mean: 58.3) who underwent horizontal glottectomy and completed at least 1 year of follow-up. To compare postoperative results, 20 similarly aged men were included as a control group; all glottectomy patients and all controls were smokers. We used three methods-acoustic and aerodynamic voice analyses, the GRBAS (grade, roughness, breathiness, asthenicity, and strain) scale, and the voice handicap index-30 (VHI-30)-to assess vocal function objectively, perceptually, and subjectively, respectively. We also assessed swallowing function objectively by fiberoptic endoscopic evaluation of swallowing (FEES) and subjectively with the M.D. Anderson dysphagia inventory (MDADI). The 22 patients were also subcategorized into three groups according to the extent of their arytenoid cartilage resection, and their outcomes were compared. Acoustic and aerodynamic analyses showed that the mean maximum phonation time was significantly shorter and the fundamental frequency was significantly lower in the glottectomy group than in the controls (p = 0.001 for both), and that the mean jitter and shimmer values and the mean harmonics-to-noise ratio were all significantly higher (p = 0.001 for all); there were no significant differences among the three arytenoid subgroups. Self-assessments revealed that there were no statistically significant differences among the three subgroups in GRBAS scale scores except for the breathiness score (p = 0.045), which was lower in the arytenoid preservation subgroup than in the total resection subgroup; there were no statistically significant differences among the three subgroups in VHI-30 scores. Finally, swallow testing found no statistically significant differences in FEES scores or MDADI scores. We conclude that horizontal glottectomy caused a deterioration in vocal function, but swallowing function was satisfactory.

Introduction: The aim of this study was to evaluate the clinical and radiological outcomes of total hip arthroplasty (THA) in patients with Ankylosing Spondylitis (AS)., Patients and Methods: One hundred five hips of 61 AS patients (mean age: 41.3 ± 10.2 years) who underwent THA between 1997 and 2012 were included into the study. Dorr's classification of proximal femoral geometry, acetabular protrusio, bone ankylosis, acetabular protrusion, Brooker classification of heterotopic ossification (HO), Gruen and Charnley classifications of implant loosening were used in radiographic assessments. Patients were called back to return for an additional long-term follow-up for functional assessment., Results: Cementless total hip arthroplasty was used in 83 hips (79%) and cemented TKA was used in 22 hips (21%). The overall rate of aseptic loosening was 7.6% at a mean follow-up of 5.4 years. Femoral loosening was statistically similar in cemented and cementless femoral components (14% vs. 8%, p = 0.089). Acetabular component loosening was statistically higher in patients with any degree of HO (p = 0.04). Regardless of the type of femoral implant (cemented or cementless), femoral component loosening was higher in Dorr's type C patients (p = 0.005). The average pre-operative HSS was 46.6 ± 16.3, and it improved to 80.7 ± 18.7 at last follow-up (p < 0.01)., Conclusion: Revision incidence was similar in between ankylosed and non-ankylosed hips. While complication rates are high, significant functional improvement can be achieved after THA in patients with AS., (Copyright © 2016 Turkish Association of Orthopaedics and Traumatology.

Objective: Morphological changes in patients subjected to surgical treatment to correct occlusal discrepancies may lead to various functional changes. The aim of the present study was to evaluate changes in lip closing force after surgically assisted rapid maxillary expansion in skeletally mature patients., Methods: The study involved 7 female and 7 male patients treated with surgically assisted rapid maxillary expansion. Maximum and minimum lip pressures of patients were measured with Lip De CumLDC-110R. The intercanine distance and incisors angulations were measured preoperatively (T0), at the end of the expansion (T1), at the end of the third month of retention (T2), and at the end of the sixth month of retention (T3)., Results: The greatest values of maximum and the minimum lip closing force were observed at the end of the expansion period significantly. The intercanine distance and inclinations of incisors measured at the third and sixth months showed a significant decrease., Conclusions: The present study demonstrated that, following surgically assisted rapid palatal expansion, both the maximum and the minimum lip closing force increases had a tendency to revert to their initial values 6 months after surgery.

Aim: This study aimed to evaluate the effects of reduction mammaplasty operation on sexual functions of the patients with macromastia and of their partners., Materials and Methods: Thirty-nine patients with macromastia and their partners were assessed for their sexual function before and 6 months after reduction mammaplasty. Sexual function of the women and their partners were evaluated using the Index of Female Sexual Function (IFSF) and the International Index of Erectile Function (IIEF), respectively. Controls (n = 33) were chosen from healthy hospital staff and their partners. Preoperative and postoperative scores were statistically compared with the controls' scores by using Student t test. Also, preoperative and postoperative scores were compared by using paired t test., Results: The mean of age and body mass index of the women and their partners in the patient and control group were similar (P = 0.07). Before the operation, the mean of IFSF scores in the patient and control group were 22.75 (3.45) and 27.28 (5.05), respectively (P < 0.001). After the operation, the mean of IFSF scores in the patient group increased significantly to 27.67 (P < 0.001). The postoperative scores of all IFSF subscales except lubrication subscale were higher than the preoperative scores. Although there was no significant difference between preoperative and postoperative IIEF-total scores, postoperative IIEF-erectile function and IIEF-intercourse satisfaction scores were significantly reduced (P < 0.05)., Conclusions: We found that macromastia adversely affected female sexual function but reduction mammaplasty eliminated this adverse effect. We also found that the partners' erectile function and intercourse satisfaction reduced after the operation. This reduction may be due to psychological effects.

Background/aims: The American Society for Gastrointestinal Endoscopy (ASGE) endoscopic retrograde cholangiopancreatography (ERCP) grading system was proposed but has not been fully evaluated with prospective clinical studies. In this study, we aimed to evaluate the effectiveness of the ERCP difficulty grading system for predicting success and adverse event rates related to the procedure., Materials and Methods: A total of 1057 ERCP procedures performed on 752 patients were included in the present study. The complexity grades of the procedures were recorded according to the ASGE grading system. Specific complications of ERCP (pancreatitis, cholangitis, bleeding, and perforation) were also defined and graded., Results: The procedure difficulty was determined as 1st degree in 153 patients (14.4%), 2nd degree in 498 patients (47.1%), 3rd degree in 271 (25.6%), and 4th degree in 135 patients (12.7%). The success rate for the entire procedures was 88.4%. The success rate for 1st degree procedures was 99.3%, 97.2% for 2nd degree procedures, 86.7% for 3rd degree procedures, and 46.7% for 4th degree procedures (p<0.005). When the difficulty of the procedures increased from 1 to 4, the adverse event rates increased from 1.3% to 10.4%., Conclusion: The findings support the evidence that the difficulty degrees of ERCP procedures can help predict the success and complication rates of the procedure. Because of the increased rates of failure and complications in more difficult cases, the procedures should be performed by experienced endoscopists in advanced centers.

Purpose: The purpose of this study was to evaluate whether the volume of perioperative fluids administered to patients undergoing maxillomandibular advancement (MMA) for treatment of obstructive sleep apnea (OSA) is associated with an increased incidence of postoperative complications and prolonged length of hospital stay., Materials and Methods: A retrospective cohort study design was implemented and patients undergoing MMA for OSA at the Mayo Clinic were identified from 2001 through 2014. The primary predictor variable was the total volume of intravenous fluids administered during MMA. The primary outcome variable was length of hospital stay in hours. Secondary outcome variables included the presence of complications incurred during postoperative hospitalization. Additional covariates abstracted included basic demographic data, preoperative body mass index, preoperative apnea-hypopnea index, preoperative Charlson comorbidity index, preoperative American Society of Anesthesiologists score, type of intravenous fluid administered, surgical complexity score, duration of anesthesia, duration of surgery, and the use of planned intensive care unit admission. Univariate and multivariable models were developed to assess associations between the primary predictor variable and covariates relative to the primary and secondary outcome variables., Results: Eighty-eight patients undergoing MMA for OSA were identified. Total fluid volume was significantly associated with increased length of stay (odds ratio [OR] = 1.34, 95% confidence interval [CI], 1.05-1.71; P = .020) in univariate analysis. Total fluid volume did not remain significantly associated with increased length of hospital stay in stepwise multivariable modeling. Total fluid volume was significantly associated with the presence of postoperative complications (OR = 1.69; 95% CI, 1.08-2.63; P = .021) in univariate logistic regression., Conclusion: Fluid administration was not found to be significantly associated with increased length of hospital stay after MMA for OSA. Increased fluid administration might be associated with the presence of postoperative complications after MMA; however, future large multicenter studies will be required to more comprehensively assess this association., (Copyright © 2015 American Association of Oral and Maxillofacial Surgeons.

Background: Data regarding the long-term outcomes of restorative proctocolectomy and ileal pouch anal anastomosis including pouch function and quality of life in the pediatric population are limited in pediatric patients., Study Design: Indications for surgery, complications, long-term function, and quality of life were evaluated in pediatric patients undergoing ileal pouch anal anastomosis. Assessment of quality of life was performed using the Cleveland Global Quality of Life score., Results: There were 433 patients with a mean age of 18.04 ± 2.9 years. Final pathologic diagnoses were ulcerative colitis or indeterminate colitis (78.3%), familial adenomatous polyposis (15.7%), Crohn's disease (5.1%), and others (0.9%). There were 237 patients (54.7%) who underwent total proctocolectomy and ileal pouch anal anastomosis; 196 (45.3%) underwent initial subtotal colectomy followed by completion proctectomy with ileal pouch anal anastomosis. Anastomosis was stapled in 352 patients (81.3%) and hand-sewn in 81 (18.7%) patients. Mean follow-up was 108.5 ± 78.4 months. At the most recent follow-up, mean Cleveland Global Quality of Life score was 0.8 ± 0.2 and numbers of daytime and night-time bowel movements were 5.3 ± 3.1 and 1.6 ± 1.3, respectively. The majority of the patients (86.8%) were fully continent or only complained of rare incontinence. Most patients had no seepage (day, 84.3%; night, 72.4%) and did not wear any pads (day, 89.3%; night, 84.3%). Most denied dietary (71.3%), social (84.8%), work (85.7%), or sexual restrictions (87.6%) at the time of last follow-up. There were 92.7% of patients who said they would undergo ileal pouch anal anastomosis again and 95.2% would recommend surgery to others., Conclusions: Restorative proctocolectomy with ileal pouch anal anastomosis can be performed in pediatric patients with acceptable morbidity and is associated with good long-term results in terms of gastrointestinal function, quality of life, and patient satisfaction., (Copyright © 2014 American College of Surgeons.

Serious neurological complications after neuraxial block, including permanent neurological injury, are rare in contemporary anesthetic practice. We report a case of a 36 year old female undergoing a venous stripping operation under combined spinal epidural anesthesia (CSE). The CSE procedure was completed after a second attempt at the L4-L5 level and the surgery was completed uneventfully. After full recovery of motor block in the recovery room, the patient was discharged to the surgical ward. Epidural patient controlled analgesia with levobupivacine 0.125% and fentanyl 2 µg/ml was initiated. 10 hours after surgery, right lower limb sensory loss and monoplegia occurred. The epidural catheter was removed and normal MRI findings were noted. After one month of physical therapy treatment and two months follow up the patient was able to walk with the aid of a walking stick. We discuss factors that might have contributed to radiculopathy and neurotoxicity as a cause of neurologic deficit.

Tension pneumocephalus is a rare and life threatening complication of intracranial surgical procedures, and requires immediate recognition and surgical intervention. Tension pneumocephalus following ventriculoperitoneal shunt surgery is extremely rare and commonly seen as a delayed complication. To our knowledge, early postoperative tension pneumocephalus after shunt surgery was reported only in one other publication. We present a case of acute tension pneumocephalus following ventriculoperitoneal shunt surgery for normal pressure hydrocephalus, which was managed well with close neurological follow-up and rapid surgical intervention. The use of the portable CT scanner in this case saved significant time, without the transport of the patient to the radiology unit, made early surgical intervention possible, and prevented morbidity and mortality.

Purpose: Various studies have been performed to find out novel treatment strategies to prevent postoperative adhesion formation. Ozone therapy (OT) is shown to reduce inflammation in several pathological conditions. Therefore, we aimed to evaluate the efficacy of OT in a rat model of experimental uterine adhesion (EUA)., Methods: Thirty female Wistar rats (200-250 g) were divided into three groups: sham, EUA and EUA+OT. EUA and EUA+OT groups were subjected to the postoperative adhesion procedure by bipolar coagulation on the uterine horns and corresponding pelvic sidewall parietal peritoneum. EUA+OT group received 0.7 mg/kg daily single dose for 3 days of ozone/oxygen mixture intraperitoneally after adhesion induction. All animals were killed on the 7th day and uterine adhesions were scored. Uterine tissues and peritoneal washing fluid were harvested for all analyses., Results: Uterine malondialdehyde levels in the EUA group were significantly higher compared to the other groups. However, in the EUA group, uterine superoxide dismutase and glutathione peroxidase activities were lower than in other groups. Peritoneal fluid TNF-α levels were found to be significantly different for all groups (p < 0.001). Macroscopic total adhesion score was significantly higher in the EUA group compared to the other groups (p < 0.001). But, total score in the EUA+OT group was lower than in the EUA group (p = 0.006)., Conclusions: Medical OT prevents postoperative uterine adhesions by modulating TNF-α levels and oxidative/antioxidative status in an experimental uterine adhesion model.

Aim: Spinal epidural fibrosis is an inherent result of surgical trauma after laminectomy. The conditions in which epidural fibrosis is excessive are in the etiology of failed back syndrome. There have been many attempts to prevent formation of epidural fibrosis. Bevacizumab which is an anti-angiogenic medication, inhibits the effect of VEGF and thereby decreases the new blood vessel formation and as a result prevents adhesions. This study shows the effect of bevacizumab on spinal epidural fibrosis developing after laminectomy in rats., Material and Methods: In this study, 20 Wistar rats were used. Rats were divided into two groups; a control group, and a bevacizumab group. Three-level laminectomy was performed on the rats. Rats in the control group only had the laminectomy. In the bevacizumab group, 2.5 mg/kg bevacizumab diluted in 0.9% NaCl with a factor of 1:10 impregnated on cotton was applied on the dura topically for 5 minutes. Three weeks later, rats were sacrificed for histopathologic examination. Epidural fibrosis tissue was graded following sacrifice., Results: Statistically, it was found that the bevacizumab group had significantly less epidural fibrosis compared to the control group (p < 0.05)., Conclusion: Bevacizumab reduced the spinal epidural fibrosis significantly that developed in rats after laminectomy via its anti-VEGF effect by blocking VEGF receptors.

Purpose: Ostomy is an important step in the treatment of patients with anorectal malformation (ARM). Sometimes this basic surgical procedure may cause a devastating complication., Methods: The medical reports of the patients with ARM who had ostomy in the past were inspected. How many of them were operated in this center or sent from others, the type of ARM, what type of ostomy performed and which place of the bowel used and the complication type and rate related to ostomy and ostomy closure were evaluated., Results: Nearly, 157 of 230 patients with ARM had ostomy during twenty-two years were evaluated. The prevelent type of ostomy was loop (50.3%) and then separated (36.9%), end (7%), double barrel (4.4%) and window (1.2%). The ostomies were located in the tranverse colon (53.5%), descending colon (24.2%), sigmoid colon (17.8), pouch colon (2.5%) and ileum (1.9). Total complication rate was found to be 15.2% (24/157) (window 100%, double barrel 42.8%, separated 15.5%, loop 11.3%, end 9%). The main complication of loop ostomies was prolapse whereas wound problems, stenosis, intestinal obstruction or perforation were serious problems of separated ostomies. Complication rate in the descending colon and tranverse colon was found to be 7.1 and 28%, respectively (p = 0.001). Any difference for complication rate between loop and separated ostomies was not found. Eighteen of separated ostomies had mucous fistula and six of them (33%) were complicated, this rate was higher than those without mucous fistula (p = 0.012). Two babies with separated ostomy were lost due to surgical complications (1.2%). Complication rate after ostomy closure was 10.7% [wound infection (4.4%), intestinal obstruction (1.7%)]., Conclusion: According to this study, ostomy performed in the descending colon carries greater risks for complication regardless of its type. Nevertheless, separated ostomy with mucous fistula should be performed by experienced hands.

The main goal in syndactyly surgery is to create a normal web space; however, it is difficult to achieve the best clinical results in older and complex cases with bony fusions and joint deformities requiring osteotomies. In these complex cases, proper postoperative wound care is difficult to achieve due to the web contractures and deformities. In our report, we introduce a new technique using a frame that we called the "Hittite Sun," which helps in proper wound management to reduce wound healing problems that lead to web creep. Between 2002 and 2006, this frame was used in operations for 46 webs, and the results were compared with those of 30 operated webs in which conventional wound management technique was used. It was found that significantly lower complication rate and lesser web creep formation was seen in these patients, which were managed using the frame, compared with the cases with conventional wound care. The frame was found to be effective for prevention of severe web creep especially in complex synpolydactyly surgery.

Aim: To compare the effectiveness of the Pfannenstiel-Kerr method (PKM) or modified Misgav-Ladach method (MMLM) in previous cesarean sections (C/Ss)., Methods: Hundred and fifteen gravidas were included with previous one C/S, using either a PKM or MMLM. Demographic characteristics, operative outcomes, surgical complications, and neonatal outcomes were compared in two groups., Results: The mean operative time (18.0 ± 3.5 vs. 23.5 ± 5.7 min; p < 0.0001) and mean extraction time (90.1 ± 41.2 vs. 208.1 ± 79.1 s; p < 0.0001) were significantly shorter in the MMLM group than the PKM group. Postoperative recovery (mobilization, normalization of bowel function, need for analgesics, time to oral feeding, and intra-operative blood loss) was similar between the MMLM and PKM groups., Conclusion: The MMLM appears to be a faster alternative to PKM for previous C/Ss, with similar results as in previous studies with primary CSs.

Objective: The aim of this study was to determine whether the timing of prophylactic antibiotics at cesarean delivery influences maternal and neonatal infectious morbidity., Study Design: This was a prospective, randomized trial. Four hundred patients that underwent elective cesarean section between June and December 2007 formed the study population. Eleven patients were excluded from the study because they needed transfusion during the cesarean section. The population was divided into two groups: Group A, antibiotic prophylaxis was applied to 194 women before skin incision and Group B, antibiotic prophylaxis was applied to 195 women after umbilical cord clamping. The occurrence of endomyometritis/endometritis, wound infection, febrile morbidity, total infectious morbidity, and neonatal complications were compared., Results: There were 389 patients enrolled. No demographic differences were observed between groups. No significant difference was found between the groups for total infectious morbidity [relative risk (RR) 1.39, 95% confidence interval (CI) 0.71-2.69] and endometritis (RR 1.40, 95% CI 0.43-4.51). There was no increase in neonatal sepsis (RR 1.47, 95% CI 0.61-3.53), sepsis workup (RR 1.35, 95% CI 0.75-2.42), need for neonatal intensive care (RR 1.77, 95% CI 0.51-6.16), and intensive care stay period (P = 0.16)., Conclusions: Time of antibiotic prophylaxis application does not change maternal infectious morbidity in cesarean section deliveries. Preoperative prophylaxis application does not affect neonate morbidity rates as stated in literature.

Background: The aims of this study were to elucidate the incidence of mitral regurgitation during off-pump coronary artery bypass (OPCAB) surgery to evaluate the relationship of the changes with ventricular function and possible mitral valve regurgitation caused by positioning., Methods: Included in the study were 60 consecutive patients who underwent CAB grafting on the beating heart. We monitored several hemodynamic variables (systolic arterial pressure, mean arterial pressure, right atrial pressure, pulmonary capillary wedge pressure, and heart rate) at baseline and after each anastomosis and used transesophageal echocardiography (TEE) routinely after sternotomy, during each anastomosis, and after completion of the operation. Valvular functions, ejection fraction, and wall motion systolic index were recorded during each TEE evaluation., Results: All of the patients underwent complete revascularization. We performed 132 consecutive OPCAB anastomoses in 60 patients (60 left anterior descending artery [LAD], 20 right coronary artery [RCA], 45 left circumflex coronary artery [LCX], and 7 diagonal artery grafts). During LCX anastomosis, 38 (84.4%) of 45 patients developed moderate mitral regurgitation. The wall motion score index (WMSI) significantly increased during CX grafting, as was demonstrated by higher WMSI values than for the RCA, diagonal, and LAD grafts. The ejection fraction was decreased significantly during CX and RCA anastomoses compared with baseline levels. The hemodynamic changes were in accord with these findings. The greatest hemodynamic compromise was seen during CX anastomosis., Conclusion: Positional mitral regurgitation occurs frequently and is a major contributor to hemodynamic instability during posterior- and lateral-wall revascularization during the OPCAB procedure.

The purpose of the present study was to investigate retrospectively which aortic clamping technique, the single clamp technique (SCT) or double clamping technique (DCT), is safer in terms of cerebral functions in patients who have undergone coronary bypass surgery. We evaluated 1100 patients who underwent coronary artery bypass graft surgery at our institute from 1998 to 2004. The two groups, SCT (n = 550, 50%) and DCT (n = 550, 50%), were comparable with respect to smoking, hypertension, hypercholesterolemia, diabetes mellitus, chronic obstructive pulmonary disease, peripheral arterial disease, history of neurological events, creatinine levels, and existence of a carotid lesion. No significant differences between the SCT and DCT groups were observed in terms of cardiac and cerebral complications perioperatively and postoperatively. Both single and double clamping techniques have advantages and disadvantages in patients undergoing coronary bypass surgery.

Objective: Postoperative atrial fibrillation (AF) is still frequent complication after cardiac surgery in spite of the improvements in the surgical procedures. There is still controversy whether or not, the absence of cardiopulmonary bypass results in a lower incidence of AF., Methods: Six hundred and seventy patients that underwent revascularization by using in situ LIMA for single vessel disease were included in this retrospective study and the patients were divided in two groups. Group I included 328 patients who underwent complete revascularization with cardiopulmonary bypass and group II consisted of 342 patients who underwent complete revascularization without cardiopulmonary bypass. Then, the incidence and predictive perioperative factors of AF in two groups were determined and compared with each other., Results: There were no significant differences between two groups with respect to the preoperative demographic characteristics of the patients. The incidence of postoperative AF was determined as 16.1% after on-pump and 14.6% after off-pump revascularization. Avoiding cardiopulmonary bypass did not decrease the incidence of postoperative AF. Sex, age over 65 years, prophylactic beta-blocker usage and left ventricular dysfunction were independent predictive factors in group I (r2=0.51; P<0.001). However, only age over 65 years and prophylactic beta-blocker usage were independent predictive factors in group II (r2=0.59; P<0.01). The rates of AF in both groups were decreased by using prophylactic beta-blocker usage (P=0.05 in group I, P<0.001 in group II)., Conclusions: There is no reduction of AF rate in myocardial revascularization without cardiopulmonary bypass. However, prophylactic beta-blocker usage decreases the incidence of AF after both on-pump and off-pump myocardial revascularization.
