RESUMO

BACKGROUND: The preoperative identification of perforators is critical to the success of perforator flaps. Several technologies, including handheld Doppler (HHD) and indocyanine green angiography (ICGA), facilitate this process; however, each technology comes with unique downsides. This study directly compares the performance of HHD and ICGA in preoperative perforator identification and measures the effects of flap thickness and body mass index (BMI) on perforator localization. METHOD: Data from preoperative HHD and ICGA assessments were compared with the criterion standard of intraoperative perforator localization. Sensitivity, specificity, accuracy, and positive predictive values were calculated for both and correlated with flap thickness and BMI. RESULTS: Thirty flaps were transferred in 30 patients across 15 different donor sites. Indocyanine green angiography had higher sensitivity, accuracy, and positive predictive value (79.2%, 74.2%, and 87.5%, respectively) than HHD (55.6%, 46.6%, and 69.4%, respectively). Perforators detected by ICGA were used as flap pedicles in 21 cases compared with 13 with HHD. There were no correlations between HHD or ICGA performance and patient BMI (both P > 0.05). Increasing flap thickness was negatively correlated with the accuracy of ICGA ( P = 0.001) but not HHD ( P > 0.05). CONCLUSIONS: Indocyanine green angiography was more sensitive, specific, and accurate than HHD in identifying perforators across various donor sites; however, its performance suffered in thicker flaps, whereas HHD did not. Patient BMI was not correlated with the performance of either technology. Additional research can further delineate the interrelationships of flap thickness and technologies for perforator localization.

RESUMO

BACKGROUND: While the goal of facial vascularized composite allotransplantation (FVCA) is to provide patients with improved physical and social function, no study has evaluated layperson perception of social acceptance and perceived career success of patients with FVCA. The purpose of this study was to determine how FVCA changes social acceptance and perceived career success of patients with facial disfiguration. METHODS: Eight hundred fifteen laypersons were surveyed through Mechanical Turk to evaluate their perceptions of patients with FVCA. Respondents were shown facial photographs of patients pre-FVCA, post-FVCA, and matched controls and evaluated these photos on 26 items of perceived social acceptance and career success. Responses were analyzed using descriptive statistics and the Wilcoxon signed-rank test. RESULTS: Both male and female post-FVCA photos were perceived as significantly more socially accepted and professionally successful than their pre-FVCA photos in at least 21 out of 26 items (P < 0.001 for all), but the posttransplant patients scored lower than their control in at least 25 out of 26 items (P < 0.001 for all). Additionally, there were discrepancies in findings based on patient gender. CONCLUSIONS: This study suggests that while FVCA has a significantly positive impact on social acceptance and perceived professional success, it does not fully reinstate these qualities. Furthermore, varying surgical outcomes and/or cognitive biases (such as gender) may impact perceptions of the individual by the public. Our findings suggest a need to standardize practices to better predict and improve outcomes and encourage surgeons to consider patient factors such as gender when planning these procedures.

RESUMO

Prepectoral breast reconstruction promises to minimize breast animation deformity and decrease pain associated with subpectoral dissection and tissue expansion. This latter benefit is particularly timely given the ongoing opioid epidemic; however, this theoretical benefit remains to be demonstrated clinically. As such, this study aimed to compare inpatient opioid use and prescription practices following prepectoral and subpectoral expander-based breast reconstruction. A retrospective review was performed of patients undergoing immediate tissue expander placement between January 2017 and April 2018. Medical records were reviewed for surgical details, 24-hour inpatient PRN opioid usage (oral morphine equivalents [OME]), and discharge prescriptions. Comparisons were made using chi-squared and student's t tests where appropriate. Two hundred and thirty-one patients were identified, (mean age 48.8 years), 222 of which met inclusion criteria. 89 underwent subpectoral and 133 prepectoral tissue expander placements. All but two subpectoral patients and two prepectoral patients were opioid-naïve. The rate of bilateral procedures did not differ between cohorts (P = .194). Overall, 94% of patients were discharged within 24 hours, and length of stay did not differ between cohorts (P = .0753). Two subpectoral and two prepectoral patients required prolonged admission due to postoperative pain. All patients were ordered standing acetaminophen, celecoxib, and gabapentin, and subpectoral patients cyclobenzaprine. Narcotic pain medication was offered on an "as needed" (PRN) basis. Opioid usage within the first 24-hours was halved in the prepectoral cohort (22.2 vs 44.5 OME, P = .0003), which was not associated with bi/unilaterality of procedure or the presence of any psychiatric conditions. The amount of opioids prescribed on discharge was not significantly different between cohorts (308.42 OME prepectoral vs 336.99 subpectoral, P = .3197). Prepectoral expander placement appears to be associated with decreased inpatient opioid use postoperatively. This may represent an opportunity to improve patient satisfaction and safety by decreasing outpatient opioid prescriptions.

RESUMO

BACKGROUND: Breast reconstruction is becoming an increasingly important and accessible component of breast cancer care. We hypothesize that prepectoral patients benefit from lower short-term complications and shorter periods to second-stage reconstruction compared with individuals receiving reconstruction in the subpectoral plane. METHODS: An institutional review board-approved retrospective review of all adult postmastectomy patients receiving tissue expanders (TEs) was completed for a 21-month period (n = 286). RESULTS: A total of 286 patients underwent mastectomy followed by TE placement, with 59.1% receiving prepectoral TEs and 40.9% receiving subpectoral TEs. Participants receiving prepectoral TEs required fewer clinic visits before definitive reconstruction (6.4 vs 8.8, P <0.01) and underwent definitive reconstruction 71.6 days earlier than individuals with subpectoral TE placement (170.8 vs 242.4 days, P < 0.01). Anesthesia time was significantly less for prepectoral TE placement, whether bilateral (68.0 less minutes, P < 0.01) or unilateral (20.7 minutes less, P < 0.01). Operating room charges were higher in the prepectoral subgroup ($31,276.8 vs $22,231.8, P < 0.01). Partial necrosis rates were higher in the prepectoral group (21.7% vs 10.9%, P < 0.01). CONCLUSIONS: Patients undergoing breast reconstruction using prepectoral TE-based reconstruction benefit from less anesthesia time, fewer postoprative clinic visits, and shorter time to definitive reconstruction, at the compromise of higher operating room charges.

RESUMO

PURPOSE: To critically examine reported data to compare patient outcomes between load-sharing and load-bearing plate fixation for edentulous mandibular fractures. MATERIALS AND METHODS: A systematic review and meta-analysis were designed to test the null hypothesis of no difference in postoperative outcomes between load-sharing and load-bearing plate fixation in atrophic, edentulous mandibular fractures. The PubMed, EMBASE, Cochrane Library, Elsevier text mining tool database, and clinicaltrials.gov trial registries were queried up until July 2016. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation method. RESULTS: A total of 1212 studies were screened for inclusion of which we included 1 high-quality Cochrane review, 6 narrative reviews, and 21 publications of case reports and case series. Overall, the quality of evidence was low. No difference was found between load-bearing and load-sharing fixation in functional recovery, nonunion, or infection. An uncontrolled case series portrayed complete functional and morphological restoration in 96.9% of patients (83.2-99.5; 95% confidence interval) in load-bearing osteosynthesis while another demonstrated the same outcome in only 40.0% of patients (17.5-65.0; 95% confidence interval). CONCLUSIONS: The authors did not find a statistically significant difference between load-bearing and load-sharing plate fixation in edentulous atrophic mandibular fracture patients; although this finding may be influenced by type 2 statistical error. Surgeons should continue to use their best clinical judgment in deciding on treatment approach for these challenging fractures. Future studies with higher level evidence are necessary to guide optimal fracture management.

RESUMO

Central giant cell granuloma is a benign, intraosseous lesion that may affect the pediatric craniofacial skeleton, particularly the mandible. When surgery is indicated, the role of the craniofacial surgeon is to ameliorate the sequelae of ablative surgery by restoring facial symmetry, ensuring appropriate postoperative occlusion, and allowing for adequate interincisal opening, all in the setting of a growing craniofacial skeleton. Herein, we report the case of a 3-year-old female presenting for reconstruction after resection of the right hemimandible proximal to the unerupted first permanent molar. We highlight the various reconstructive challenges associated with mandibular reconstruction during primary dentition and make a case for the use of a costochondral graft, with a successful outcome demonstrated at 2 years of follow-up.

RESUMO

OBJECTIVE: Mandibular distraction osteogenesis (MDO) aims to relieve tongue-based airway obstruction in Robin Sequence (RS). We investigated direct laryngoscopy grade (DLG) improvement and difficult airway (DA) resolution following MDO. DESIGN: Retrospective cohort analysis. SETTING: Three tertiary care institutions. PATIENTS: Sixty-four infants with RS who underwent a single MDO procedure in their first year of life were identified from January 2010 to January 2019. MAIN OUTCOME MEASURES: The primary outcome was DLG pre- and post-MDO. Secondary outcomes included DA designation, pre- and post-MDO polysomnographic assessment for obstructive sleep apnea (OSA), length of stay, need for gastrostomy, and major/minor adverse events. RESULTS: Median DLG improved from II pre-MDO to I at the time of distractor removal (n = 43, P < .001). No significant change was seen in patients with a third recorded time point (eg, palatoplasty; n = 78, P = .52). Twenty-six (47%) of 55 patients were designated as DA pre-MDO, and 10 (18%) of 55 patients retained the label post-MDO (P < .01). Five (50%) of these 10 patients appeared to be inappropriately retained. Median obstructive apnea-hypopnea index improved from 38.6 (range 31.2-62.8) pre-MDO to 2.9 (range 1-3.9) post-MDO (n = 12; P = .002). CONCLUSION: Mandibular distraction osteogenesis allowed for DLG improvement that was stably maintained as well as functional improvement in OSA, with minimal morbidity. Difficult airway designation persisted in the electronic record of some infants despite clinical resolution.

RESUMO

PURPOSE: The purpose of this study was to determine whether the timing of mandibular fracture repair within the academic year affects the complication rate using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. MATERIALS AND METHODS: The ACS-NSQIP database was accessed and queried from 2008 to 2017 for all Current Procedural Terminology codes pertaining to open treatment of mandibular fractures. The cases were stratified into 2 groups based on academic quarter: the quarter 1 (Q1) group (July-September) and the remaining-quarters group. The inclusion criteria encompassed all Current Procedural Terminology codes in the ACS-NSQIP registry that defined mandibular fractures and age greater than 18 years. Demographic characteristics, as well as medical and surgical complications, were compared between the 2 cohorts. Descriptive statistics were calculated to characterize and compare patient cohorts, and Fisher exact test and χ2 analyses were performed to compare complication rates between groups. RESULTS: The Q1 group included 614 cases, and the remaining-quarters group included 1,454. The most common individual complications included wound dehiscence (1.6% overall; 2.1% in Q1 group vs 1.4% in remaining-quarters group, P = .22), combined superficial and deep-space infection (4.9% overall; 4.4% in Q1 group vs 3.3% in remaining-quarters group; P = .91 and P = .21, respectively), and reoperation (3.9% overall; 4.6% in Q1 group vs 3.6% in remaining-quarters group, P = .29). Medical complications including acute kidney injury, venous thromboembolism, urinary tract infection, and sepsis or septic shock were rare (<1%). Complication rates did not significantly differ between the third quarter and the remainder of the year on bivariate analysis. CONCLUSIONS: Our results do not support the idea of a "July effect" regarding postoperative outcomes after mandibular fracture repair. Further studies are needed to elucidate this phenomenon within all procedures under the wide umbrella of the specialty.

RESUMO

PURPOSE: The purpose of this study was to determine if there is an increased postoperative complication rate in orthognathic surgery during the first academic quarter (Q1) (July to September). MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was accessed to identify cases with Current Procedural Terminology codes pertaining to orthognathic procedures from 2008 to 2017. Procedures were separated into 2 groups based on time in the academic year: Q1 (July to September) versus remaining quarters (RQ). The inclusion criteria were Current Procedural Terminology codes representing operations resulting in movement of the dentate portion of the jaws and age of 18 years or older. Patient demographic characteristics and perioperative complications were compared between the groups. Descriptive statistics, Fisher exact tests, and χ2 tests were executed. RESULTS: The Q1 cohort included 877 cases, and the RQ cohort included 2,062 cases. The average age of patients was 47.0 ± 19.5 years in Q1 versus 47.2 ± 19.4 years in RQ. The most frequent complications were blood transfusion (11.97% in Q1 vs 12.57% in RQ, P = .64), reoperation (8.67% in Q1 vs 8.84% in RQ, P = .87), and combined superficial and deep-space infection (5.02% in Q1 vs 5.76% in RQ, P = .51). Medical complications involving other organ systems were rare (<1%). Analyses showed no significance between complication rate and time of year. CONCLUSIONS: The results of this study indicate that there is no association between time of year and complication rates after orthognathic surgery. Additional investigations could be useful in shining light on this topic as it pertains to the training of future surgeons.

RESUMO

PURPOSE: The purpose of this study was to characterize the types of craniomaxillofacial (CMF) injuries that occur in professional sports leagues and the associated recovery times. MATERIALS AND METHODS: A retrospective cohort study was designed and implemented using the Pro Sports Transaction Archive. The database was queried for all registered CMF injuries in the 4 main men's major professional sports leagues in the United States from 2013 to 2018. The sport, injury location, and season were the predictor variables, and the frequency and length of time on the injured list were the outcome variables. Descriptive statistics were computed, and Fisher's exact tests were used to determine the association between the predictor and outcome variables. Analysis of variance was used to compare the injury frequency and duration. RESULTS: Of the 198 injuries that met the inclusion criteria, 60 were from Major League Baseball (MLB) (30%), 49 from the National Basketball Association (25%), 8 from the National Football League (4%), and 81 from the National Hockey League (NHL) (41%). Injuries to the midface were most common (mean, 25.2 ± 3.6 injuries per season; P < .001) compared with the upper face (mean, 6.0 ± 2.0 injuries per season) and lower face (mean, 8.4 ± 2.3 injuries per season). The mean time on the injured list after CMF trauma was 8.4 ± 10.4 days, with MLB injuries requiring the shortest duration (mean, 3.9 ± 6.6 days; P = .001). A significant association was found between the injury location and sport (P < .001). However, no statistically significant difference was found in the number of injuries per season from 2013 to 2018 for each league (P = .818). CONCLUSIONS: Midface trauma was significantly more common than upper or lower face trauma in professional sports leagues during the past 5 seasons. The NHL had the greatest injury rate, even after adjustment for games played.

RESUMO

PURPOSE: To date, no clear evidence-based guidelines exist pertaining to the ideal timing to perform surgical treatment of orbital fractures. The purpose of this study was to determine if early treatment of orbital fractures resulted in better patient outcomes. MATERIALS AND METHODS: We designed and implemented a systematic review and meta-analysis to test the null hypothesis of no difference in outcomes between different time intervals between orbital injury and surgical intervention. PubMed, Embase, the Cochrane Library, the Elsevier text mining tool database, and clinicaltrials.gov trial registry were queried. The quality of evidence was based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. The predictor variable was the timing of operative repair (early vs late). The outcome variable was complete recovery. Other variables of interest were diplopia, enophthalmos, and preoperative motility restriction. Meta-analyses were performed when definitions of active and control interventions and patient outcomes were deemed similar. In addition, χ2 tests were performed to determine differences in clinical outcomes between early and late operative repair. RESULTS: Of the 1,160 articles reviewed, 20 met the inclusion criteria. Surgery performed less than 2 weeks after injury was significantly associated with greater odds of complete recovery of symptoms (odds ratio [OR], 6.9 [95% confidence interval (CI), 1.35-35.06]), as well as a lower incidence of postoperative diplopia (OR, 0.3 [95% CI, 0.1-0.9]) and enophthalmos (OR, 0.2 [95% CI, 0.1-0.9]). Repair performed less than 30 days after injury was associated complete resolution of preoperative motility restriction (OR, 24.6 [95% CI, 1.30-462.34]) as well as diplopia. CONCLUSIONS: Differences in the timing of surgery and definition of patient outcomes, as well as variations in methods of evaluating postoperative outcomes, potentiate the risk of bias and warrant downgrading of the quality of evidence in a study. The timing of repair varied among 2, 4, and 8 weeks after injury. However, a short time to surgical intervention was significantly associated with resolution of vertical dystopia, postoperative enophthalmos, and motility restriction.

RESUMO

BACKGROUND: Current Procedural Terminology (CPT) codes are an important part of surgical documentation and billing for services provided within the United States. This limited coding language presents a challenge in the heterogenous and rapidly evolving field of craniofacial surgery. The authors aimed to survey members of the American Society of Maxillofacial Surgery (ASMS) to characterize the variability in coding practices in the surgical management of craniofacial trauma. METHODS: A cross-sectional of 500 members of the ASMS survey was carried out. Descriptive statistics were calculated. The effect of various practice characteristics on coding practices was evaluated using Chi-squared tests and Fisher's exact tests. RESULTS: In total, 79 participants responded including 77 plastic surgeons. About 75% worked in academic centers and 38% reported being in practice over 20 years. Coding practices were not significantly associated with training background or years in practice. Unilateral mandibular and unilateral nasoorbitoethmoid fractures demonstrated the greatest agreement with 99% and 88% of respondents agree upon a single coding strategy, respectively. Midface fractures, bilateral nasoorbitoethmoid fractures, and more complex mandibular demonstrated considerable variability in coding. CONCLUSION: There is a wide variability among members of the ASMS in CPT coding practices for the operative management of craniofacial trauma. To more accurately convey the complexity of craniofacial trauma reconstruction to billers and insurance companies, the authors must develop a more descriptive coding language that captures the heterogeneity of patient presentation and surgical procedures.

RESUMO

The tissues of the medial arm as a donor site for perforator flap design have several advantages. However, they are relatively underused with limited reports, partly due to unreliable perforator anatomy. Therefore, we aimed to review our preliminary experience using indocyanine green (ICG) angiography to design and elevate preexpanded pedicled brachial artery perforator (BAP) flaps for regional reconstruction. All patients underwent soft tissue reconstructions using a preexpanded BAP flap in two or three stages. ICG angiography was used to localize perforators during both expander insertion and flap elevation. The pedicle was divided at the third stage 3 weeks following flap elevation for head and neck cases. Sixteen patients underwent reconstructions of the head and neck (n = 13) or shoulder/trunk (n = 3) using 14 perforator-plus and 2 propeller BAP flaps. In total, 50 perforators were identified using ICG imaging, all of which were appreciable during both expander placement and flap elevation. Thirty-five perforators were directly visualized during flap elevation, and an additional 15 perforators were not explored but incorporated into the flap. All flaps survived without necrosis, and the donor sites healed uneventfully without complications. The medial arm provides thin and pliable skin for the resurfacing of regional defects with relatively minimal donor-site morbidity. With the assistance of ICG angiography, perforators of the brachial artery can be reliably identified, facilitating the preexpansion and elevation of pedicled BAP flaps for use in head-neck and trunk reconstruction.

RESUMO

BACKGROUND: This study aims to directly compare measurements of tissue oxygenation obtained using the Intra.Ox (Vioptix Inc., Fremont, CA) near infrared spectrometer with the perfusion assessment of the indocyanine green (ICG)-based SPY Elite imaging system (Stryker Co., Kalamazoo, MI) in a porcine bowel model. METHODS: Two live minipigs underwent laparotomy and isolation of a 30-cm segment of a large bowel. Standardized oximetry measurements were taken along the segment of bowel immediately before, after, and serially for 30 minutes following transection. A 0.5 mg/kg dose of ICG was then injected intravenously and the SPY Elite system was used to visualize and quantify tissue perfusion. Pearson's correlation coefficients were calculated using the outcomes. RESULTS: Transected and ligated bowel yielded mean Intra.Ox measurements of 61% oxygenation at the proximal base of the limb and 27.8% at the distal edges. Analysis of the relative ICG fluorescence using the SPY Elite's proprietary software yielded perfusion estimates of 64.8% proximally and 6.8% distally. Intra.Ox and SPY Elite measurements demonstrate a Pearson product-moment correlation of 0.929. Repeat measurements at 15-mm intervals along the tissue yielded decreasing Intra.Ox measurements along the length of the flap that correlate to SPY Elite measurements (r = 0.645). CONCLUSION: Both the Intra.Ox and the SPY detected clinically relevant changes in bowel oxygenation following transection and ligation. The use of intravenous ICG dye did not appear to affect measurements of tissue oxygenation obtained using the Intra.Ox.

RESUMO

BACKGROUND: As deep inferior epigastric artery perforator (DIEP) flaps have gained popularity in breast reconstruction, the postoperative care of these patients, including the appropriate hospital length-of-stay and the need for intensive care unit (ICU) admission, has become a topic of debate. At our institution, we have adopted a pathway that aims for discharge on postoperative day 3, utilizing continuous tissue oximetry without ICU admission. This study aims to evaluate outcomes with this pathway to assess its safety and feasibility in clinical practice. METHODS: A retrospective review was performed of patients undergoing DIEP flap breast reconstruction between January 2013 and August 2014. Data of interest included patient demographics and medical history as well as complication rates and date of hospital discharge. RESULTS: In total, 153 patients were identified undergoing 239 DIEP flaps. The mean age was 50 years (standard deviation [SD] = 10.2) and body mass index (BMI) 29.4 kg/m2 (SD = 5.2). Over the study period, the flap failure rate was 1.3% and reoperation rate 3.9%. Seventy-one percent of patients were discharged on postoperative day 3. Nine patients required hospitalization beyond 5 days. Theoretical cost savings from avoiding ICU admissions were $1,053 per patient. CONCLUSION: A pathway aiming for hospital discharge on postoperative day 3 without ICU admission following DIEP flap breast reconstruction can be feasibly implemented with an acceptable reoperation and flap failure rate.

RESUMO

PURPOSE: Controversy remains regarding the optimal degree of anatomic exposure, reduction, and fixation required during open reduction and internal fixation of zygomaticomaxillary complex (ZMC) fractures. We critically examined the reported data to compare the patient outcomes after various degrees of ZMC reduction and internal fixation. MATERIALS AND METHODS: A systematic review and meta-analysis were designed to test the null hypothesis of no difference in outcomes between different degrees of fixation of ZMC fractures. The PubMed, EMBASE, Cochrane Library, Elsevier text mining tool database, and clinicaltrials.gov trial registries were queried. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation method. RESULTS: Of 1213 screened studies, 13 met the inclusion criteria. Fracture instability at 3 months was greater with 2-point fixation (61.1%) than with 3-point fixation (10.6%; relative risk, 2.5, 95% confidence interval [CI], 1.4 to 3.3). Less vertical orbital dystopia was seen with 3-point fixation than with 2-point fixation (mean difference, 0.9 mm; 95% CI, 0.6 to 1.3 mm). The incidence of infection and malar asymmetry did not differ between the groups. The quality of evidence was very low to low. CONCLUSIONS: The reported data were limited by low quality, retrospective studies. However, the meta-analysis of randomized control trial data suggested a superiority of 3 points of exposure and fixation regarding fracture stability. When 2 points appear to provide stable fixation, the potential benefits of a third point should be weighed against the cost, operative time, and exposure/periosteal stripping on a case-by-case basis.

RESUMO

Congenital masses in the lateral brow are most commonly dermoid cysts and can often be excised surgically without additional investigation. These dermoids may rarely develop intracranial extension due to underlying bony erosions and become less prominent over time - a "disappearing dermoid." However, the authors present an unusual alternative case in which an off-midline frontal encephalocele initially presented as a firm irreducible mass but exhibited changing characteristics over time.

RESUMO

INTRODUCTION: Correction of severe orbital and globe malposition from neurofibromatosis remains a significant clinical challenge. Current techniques including zygoma osteotomy, bone grafting, or placement of orbital implants do not adequately address aberrant anatomy, under-correct the deformity, and are prone to relapse. The authors have developed the orbital box segmentation osteotomy to reduce vertical orbital height and translocate the orbit and use patient-specific custom internal orbital titanium implants to close the cranio-orbital communication-reestablishing both the external orbital shape and internal orbital volume. METHODS: Virtual surgical planning with contralateral mirror imaging was used to design symmetrical repositioning of the external orbit and to determine segmentation required to reduce the vertical excess and inferior rim malposition as well as for manufacturing patient-specific titanium implants. Orbital volume was measured from preoperative, virtual surgical simulation, and postoperative imaging using stereotactic software. Globe position was assessed using pre- and postoperative 3-dimensional photography software (Canfield). RESULTS: All patients (n = 3, mean age 12 years) demonstrated improved globe position and orbital contour with resolution of globe pulsatility. Virtual surgical planning predicted postoperative volumes within 0.8 cm ±â€Š0.5. Mean volume orbital change was 4.5 cm, change in conformation and distribution of orbital volume was present in all patients. Vertical globe position improved from 11.5 mm preoperatively to within 1 mm of the unaffected side postoperatively. One patient had surgical site infection, there is no evidence of relapse at mean 24-months follow-up. CONCLUSION: Segmental box osteotomy with internal orbital reconstruction redistributes orbital volume safely and accurately addresses globe malposition from neurofibromatosis.

RESUMO

BACKGROUND: The use of subgaleal drains following primary cranioplasty for craniosynostosis has undergone limited investigation. Proposed benefits include prevention of seroma, detection of postoperative bleeding, and cerebrospinal fluid leak. We conducted a systematic review of the literature and surveyed craniofacial surgeons to ascertain the current evidence pertaining to drain use following primary cranioplasty for craniosynostosis and to determine surgical practice patterns. METHODS: PubMed and Embase databases were searched to identify relevant articles. Abstracts were reviewed by 2 investigators, and a Cohen κ statistic was calculated. Patient demographic and outcome data were extracted and compared. A 9-question survey was e-mailed to active and associate members of the American Society of Craniofacial Surgeons. RESULTS: A total of 7395 unique citations were identified. Only 2 retrospective chart reviews met inclusion criteria. All objective parameters demonstrated no difference between patients with and without drains. A subjective benefit of limiting facial swelling was proposed without objective analysis. Fifty (32.5%) of the 154 craniofacial surgeons responded to the survey. Forty-two percent used postoperative drains. A significant association (P = .01) was found between the belief that drains limited facial swelling and their use. CONCLUSIONS: The literature examining postoperative drain use in primary cranioplasty for craniosynostosis is restricted. The current studies show no definite benefit to drain use but are limited in their assessment of key outcomes. There is wide variability among surgeons regarding drain use, and this seems to be motivated by belief and tradition.

RESUMO

OBJECTIVE: To better understand the capacity for orthodontic care, service features, and finances among members of the American Cleft Palate-Craniofacial Association (ACPA). DESIGN: Cross-sectional survey. SETTING: ACPA-approved multidisciplinary cleft teams. PARTICIPANTS: Cleft team coordinators. INTERVENTIONS: Coordinators were asked to complete the survey working together with their orthodontists. MAIN OUTCOME MEASURE: Model for orthodontic care. RESULTS: Coordinators from 82 out of 167 teams certified by ACPA completed the survey (response rate = 49.1%). Most orthodontists were private practice volunteers (48%) followed by university/hospital employed (22.8%). Care was often delivered in community private practice facilities (44.2%) or combination of university and private practice facilities (39.0%). Half of teams reported offering presurgical infant orthopedics (PSIO), with nasoalveolar molding being the most common. Cleft/craniofacial patients typically comprise 25% or less of the orthodontists' practices. The presence of a university/hospital-based orthodontist was associated with higher rates of offering PSIO (P < .001) and an increased percentage dedication of their practice to cleft/craniofacial care (P < .001). CONCLUSION: Orthodontic models across ACPA-certified teams are highly varied. The employment of full-time craniofacial orthodontists is less common but is highly correlated with a practice with a high percentage of cleft care and the offering of advanced services such as PSIO. Future work should focus on how to effectively promote such roles for orthodontists to ensure high-level care for cleft/craniofacial patients requiring treatment from infancy through skeletal maturity.
