Sequential free fibula transfers: Quality of life and systematic review.

BACKGROUND: Successive osteoseptocutaneous fibula transfers for jaws reconstruction are rare but important options. This study contributes patient-reported and clinical outcomes, as well as systematically reviews all existing reports. METHODS: All sequential fibula transfers performed by the senior author were reviewed from a prospectively managed database, including University of Washington quality of life (UWQoL). Systematic review was conducted in PubMed and Cochrane databases for similar publications. RESULTS: Eighteen patients (average age 51.5 years) received sequential fibulas (mean 4.7 years between reconstructions). Secondary fibulas more often had benign indications (72.2% vs. 33.3%, p = .04), most commonly osteoradionecrosis (38.9%). At a mean follow-up of 30.5 months, the average interincisal distance increased from 21.8 to 27.6 mm, and 92.3% tolerated an oral diet following the second fibula. Eight patients completed the UW-QoL before and after the second fibula, and three prior to the first fibula. Composite physical function was significantly decreased from 96.7 prefibula reconstruction to 63.3 following the first (p < .001) and 64.2 after the second fibula (p < .001). There were no differences in other domains. The systematic review yielded six articles reporting 56 patients (mean 39 months between fibulas). Secondary fibulas were performed for repeat malignancy (45%) and osteoreadionecrosis (39%), resulting in elevated tube feeding from 20% following the first to 39% following the second, but overall high quality of life in two studies. CONCLUSIONS: Sequential osteoseptocutaneous fibula reconstructions of jaws are often performed for benign indications such as osteoradionecrosis. Overall function and QoL are comparable with those following the first fibula transfer.

Impact of post-operative infection on revision procedures in breast reconstruction: A marketscan database analysis.

BACKGROUND: Esthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures. METHODS: We conducted a retrospective database study (2007-2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes. Severe capsular contracture (Grade 3-4) was defined as requiring capsulotomy or capsulectomy with implant removal or replacement. Moderate and severe soft-tissue defects were determined by the need for fat grafting or breast revision, respectively. Generalized linear models were used, adjusting for comorbidities and surgical factors (p < 0.05). RESULTS: We analyzed the data on 62,510 eligible patients. Post-operative infections increased the odds of capsulotomy (OR 1.59, p < 0.001) and capsulectomy (OR 2.30, p < 0.001). They also raised the odds of breast revision for severe soft-tissue defects (OR 1.21, p < 0.001). There was no significant association between infections and fat grafting for moderate defects. Patients who had post-operative infections were also more likely to experience another infection after fat grafting (OR 3.39, p = 0.0018). In two-stage reconstruction, infection after tissue expander placement was associated with greater odds of infection after implant placement. CONCLUSION: Post-operative infections increase the likelihood of developing severe soft-tissue defects and capsular contracture requiring surgical revision. Our data reinforce the role of infections in the pathophysiology of capsular contracture. Additionally, infections elevate the risk of subsequent infections after fat grafting for moderate defects, further increasing patient morbidity.

Risk Factors for Hardware Removal Following Bimaxillary Surgery: A National Database Analysis.

Orthognathic surgery typically relies on the rigid fixation of fracture fragments using metal hardware. Though hardware is usually intended to be implanted permanently, the removal of hardware (ROH) is sometimes indicated for a variety of reasons. The authors sought to identify risk factors for ROH following orthognathic surgery. The authors conducted a retrospective analysis of the Merative MarketScan Research Databases, 2007-2021 using Current Procedural Terminology (CPT) and International Classification of Disease (ICD-9 and ICD-10) codes to identify patients who underwent an index Le Fort 1 osteotomy and bilateral sagittal split osteotomy operation on the same day. Statistical analysis involved χ2, Shapiro-Wilk, Wilcoxon-Mann-Whitney, Poisson regression, and multivariable logistic regression tests. 4698 patients met the inclusion criteria. The mean age at surgery was 25 years, and 57% were female. ROH occurred in 5.9% of patients. The mean time to hardware removal was 190.5±172.4 days. In a multivariate logistic regression, increased odds of ROH were associated with older patient age [OR: 1.02 (1.01-1.03), P=0.046], sleep apnea [OR: 1.62 (1.13-2.32), P=0.018], and craniofacial syndrome and/or cleft diagnoses [OR: 1.88 (1.14-2.55), P<0.001]. In the same model, postoperative oral antibiotic prophylaxis was not associated with ROH (P=0.494). The incidence of all-cause complications [IRR: 1.03 (1.01-1.05), P<0.001] rose over the study period, while the incidence of ROH did not change significantly (P=0.281). Patients at elevated risk should be counseled on the increased possibility of a second operation for ROH before having orthognathic surgery to ensure expectations and health care utilization decisions align with the evidence.

Safety and efficacy of intracranial vascularized submental lymph node transfer for treating hydrocephalus.

Hydrocephalus is routinely treated with ventriculoperitoneal shunt drainage of cerebrospinal fluid (CSF), a procedure plagued by high morbidity and frequent revisions. Vascularized submental lymph node (VSLN) transplants act as lymphatic pumps to drain interstitial fluid (ISF) from lymphedematous extremities. As the field of neuro-lymphatics comes to fruition, we hypothesize the efficacy of VSLN in the drainage of intracranial CSF-ISF. We report novel placement of VSLN in the temporal subdural space in two patients diagnosed with symptomatic communicating hydrocephalus. At a minimum follow-up of 1 month postoperatively, both experienced radiological and clinical improvements.

Evolution of free flap reconstruction in the upper extremity: perspective from a tertiary plastic and reconstructive institution.

Soft tissue reconstruction of the upper extremity requires consideration of wound bed status, varied anatomic composition, future function and tissue match, whether in thickness, pliability or involvement of other tissue components. Of the options available, microvascular free tissue flaps allow maximal customizability with the avoidance of long-term donor site morbidity. Free tissue transfers have evolved, given increased surgical proficiency, from direct vessel-based flaps to septocutaneous vessel-based flaps, to musculocutaneous perforator flaps, and most recently to free-style free flaps. With increases in technical complexity come limitless alternatives. We documented the progression of free flap upper extremity reconstruction in recreating form and function of the upper extremity. The foundations laid should allow surgeons the freedom and versatility to choose the most faithful restoration of the defect and produce the best functional and aesthetic results.

ChatGPT in head and neck scientific writing: A precautionary anecdote.

PURPOSE: To evaluate the accuracy of ChatGPT references in scientific writing relevant to head and neck surgery. MATERIALS AND METHODS: Five commonly researched keywords relevant to head and neck surgery were selected (osteoradionecrosis of the jaws, oral cancer, adjuvant therapy for oral cancer, TORS, and free flap reconstruction in oral cancer). The AI chatbot was then asked to provide ten complete citations for each of the keywords. Two independent authors reviewed the results for accuracy and assigned each article a numerical score based on pre-selected criteria. RESULTS: Among 50 total references provided by ChatGPT, only five (10 %) were found to have the correct title, journal, authors, year of publication, and DOI. Merely 14 % of the presented references had correct DOI. References regarding free flap reconstruction for oral cancer were the least accurate from all the five categories, with no correct DOI. Complete inter-rater agreement was noted while evaluating the citations. CONCLUSION: Only 10 % of the articles provided by ChatGPT, relevant to head and neck surgery, were correct. A high degree of academic hallucination was noted.

Hypertrophic chondrocytes at the junction of musculoskeletal structures.

Hypertrophic chondrocytes are found at unique locations at the junction of skeletal tissues, cartilage growth plate, articular cartilage, enthesis and intervertebral discs. Their role in the skeleton is best understood in the process of endochondral ossification in development and bone fracture healing. Chondrocyte hypertrophy occurs in degenerative conditions such as osteoarthritis. Thus, the role of hypertrophic chondrocytes in skeletal biology and pathology is context dependent. This review will focus on hypertrophic chondrocytes in endochondral ossification, in which they exist in a transient state, but acting as a central regulator of differentiation, mineralization, vascularization and conversion to bone. The amazing journey of a chondrocyte from being entrapped in the extracellular matrix environment to becoming proliferative then hypertrophic will be discussed. Recent studies on the dynamic changes and plasticity of hypertrophic chondrocytes have provided new insights into how we view these cells, not as terminally differentiated but as cells that can dedifferentiate to more progenitor-like cells in a transition to osteoblasts and adipocytes, as well as a source of skeletal stem and progenitor cells residing in the bone marrow. This will provide a foundation for studies of hypertrophic chondrocytes at other skeletal sites in development, tissue maintenance, pathology and therapy.

Differential Pulley Release in Trigger Finger: A Prospective, Randomized Clinical Trial.

BACKGROUND: The palmar aponeurosis or "A0 pulley" may play a role in trigger finger pathology. This study assesses the involvement of the A0 pulley in patients receiving trigger finger release. METHODS: This single-surgeon, prospective, randomized clinical trial was conducted among consenting patients with symptomatic trigger finger. Intraoperative coin toss was used to randomize initial release of either the A0 or A1 pulley. Following release, active flexion and extension of the affected digit were examined. The remaining pulley was then released in sequence, and clinical trigger status was recorded. RESULTS: Thirty fingers from 24 patients were released; 17 fingers received A0 release first, and 13 received A1 release. Following initial A0 release, 8 fingers (47%) demonstrated complete resolution of symptoms, 4 (24%) demonstrated improvement but incomplete resolution of triggering, and 5 (29.4%) demonstrated no improvement. Following initial A1 release, 6 fingers (46%) demonstrated complete resolution, 3 (23%) demonstrated improvement but incomplete resolution of triggering, and 4 (31%) demonstrated no improvement. All patients demonstrated complete resolution after surgical release of both sites. Neither initial A1 release nor initial A0 release was statistically associated with complete, incomplete, or failed symptom resolution. CONCLUSIONS: These data implicate the A0 pulley as the primary cause of 31% to 47% of trigger fingers in our study. Although larger trials are needed to validate these results, our study suggests that release of both A0 and A1 pulleys may offer greater symptom resolution than release of the A1 pulley alone.

Persistent Cranial Defects After Endoscopic Sagittal Synostosis Surgery.

INTRODUCTION: Incomplete cranial ossification is a rare complication of calvarial-vault remodeling for sagittal synostosis often requiring reoperation. Studies show an incidence ranging from 0.5% to 18%. METHODS: Infants with sagittal synostosis who underwent endoscopic sagittal synostectomy and barrel stave osteotomies with postoperative orthotic helmeting between 2003 and 2021 were included with minimum follow-up until the completion of helmeting. RESULTS: Of 90 patients, 86 met inclusion; 3 had defects (3.5%). Patients with and without cranial defects had no difference in age of surgery (113 versus 131 d), duration helmeting (6.6 versus 7.0 mo), or perioperative/postoperative complications. Two underwent reoperation for recurrence. Patients with cranial defects manifested the evidence of developmental concerns more than patients without (100% versus 16.9%).The average cranial defect size was 19.33 cm 2 and age at surgery 4.29 years. All were managed with cranial particulate bone grafting with addition of bone matrix and SonicWeld plate. The first had 6×6 cm posterior defect requiring cranioplasty at 4.86 years with excellent healing. The second had a 3×6 cm posterior and 1×1 cm anterior defect, underwent cranioplasty at 4.14 years with persistent 4×6 defect, requiring repeat cranioplasty at 5.3 years. The third had a 3×5 cm posterior defect and underwent cranioplasty at 3.88 years with continued defect, planning for repeat intervention. CONCLUSIONS: This is the largest documented series of reoperations for incomplete ossification after endoscopic sagittal synostectomy with postoperative helmet treatment. The authors report a 3.5% rate of cranial defects, managed with bone grafting, bone matrix, and absorbable plates. Patients with poor ossification may have a propensity toward developmental concerns.

Virtual Neurocognitive Testing in Craniofacial Surgery.

SUMMARY: Digital communication platforms have had an impact on plastic surgery research. Although neurocognitive testing is an important tool for understanding the long-term developmental outcomes of congenital craniofacial conditions, testing has been geographically limited because of its interactive nature. Virtual neurocognitive testing is a facsimile version of in-person testing that allows researchers to overcome this limitation with high fidelity. Ten school-age subjects completed a neurocognitive assessment battery measuring intelligence quotient, academic achievement, and visuomotor skills at an average age of 7.8 ± 1.4 years. The subjects then retook the same battery through an identical virtual testing method approximately 1 year after the initial test. There were no significant differences in verbal intelligence quotient (p = 0.878), performance intelligence quotient (p = 0.813), and full-scale intelligence quotient (p = 0.982) scores obtained through in-person and virtual tests. There were no significant differences between academic achievement letter and word recognition (p = 0.999), math computation (p = 0.619), reading comprehension (p = 0.963), and spelling (p = 0.344) scores. There were no significant differences in visuomotor integration (p = 0.158), visual perception (p = 0.798), and motor coordination (p = 0.796) scores obtained through the two methods. The median at-home time to set up study equipment for the virtual testing was 5.0 minutes (interquartile range, 2.3 minutes). Seventy percent of participants reported that they preferred participating in research from home. All participants stated that the virtual research study was an overall positive experience. Virtual neurocognitive testing is an effective method of performing high-fidelity neurocognitive assessments while overcoming geographic barriers.

Labiaplasty: Analysis of the National Surgical Quality Improvement Program Database.

BACKGROUND: Labiaplasty is an increasingly popular procedure performed for both cosmetic and pathologic etiologies. Questions have been raised regarding the efficacy of the procedure, especially for cosmetic etiologies. OBJECTIVES: The aim of this study was to examine the complication profiles of labiaplasties for both cosmetic and pathologic etiologies. METHODS: The 2005 to 2017 National Surgical Quality Improvement Program database was analyzed for patients who, according to the relevant Current Procedural Terminology code, had undergone labiaplasties. Our cohort was further separated into cosmetic and pathologic groups based on International Classification of Diseases codes. Information was collected on patient demographic characteristics, patient comorbidities, and operative variables. Outcomes of interest included surgical complications and delayed length of stay (DLOS). A univariate analysis and multivariate logistic regression were applied to determine statistically significant predictors of our outcomes of interest for both etiologies. RESULTS: There were 640 patients in the cosmetic cohort and 1919 patients in the pathologic cohort. There were no significant differences in rates of surgical complications between the 2 groups, but there was a statistically significant increase in length of stay for the pathologic group. Univariate analysis revealed operative time and plastic surgeon specialty to be predictive of DLOS in the cosmetic cohort. No covariates were implicated with multivariate analysis for either surgical complications or for DLOS in the cosmetic cohort. CONCLUSIONS: Our findings suggest that cosmetic labiaplasty is a safe and efficacious procedure with low complication rates and no predictors of adverse outcomes.

A Comparison of BREAST-Q Scores between Prepectoral and Subpectoral Direct-to-Implant Breast Reconstruction.

BACKGROUND: Subpectoral breast implant placement has in recent history predominated in breast reconstruction, but there has been more recent adoption of prepectoral implant reconstruction. There has been limited study to date of patient-reported outcomes comparing the two techniques. METHODS: Patients who underwent direct-to-implant breast reconstruction between 2013 and 2018 were included in this retrospective cohort study. Eligible patients were asked to complete BREAST-Q domains comparing quality of life and satisfaction. Descriptive, t test, chi-square test, and multivariate linear regression analyses were performed to compare BREAST-Q scores. Significance was defined as p ≤ 0.05. RESULTS: There were 64 patients (114 breasts) who underwent prepectoral reconstruction and 37 patients (68 breasts) who underwent subpectoral reconstruction. Among the 101 women (182 breasts), there were no significant differences between BREAST-Q scores and implant position for the Satisfaction with Breasts domain (adjusted p = 0.819), Psychosocial Well-being domain (adjusted p = 0.206), or Physical Well-being Chest domain (adjusted p = 0.110). The subpectoral implant cohort was associated with higher scores, 53 versus 47, for the Sexual Well-being module (adjusted p = 0.001). CONCLUSIONS: Patients undergoing direct-to-implant breast reconstruction had comparable BREAST-Q satisfaction scores for most modules regardless of implant plane. The subpectoral implant cohort scored higher for sexual well-being.

AAPS Podium Presentations-Has the Level of Evidence Changed over the Past Decade?

An increase in the number and quality of randomized controlled trials (RCTs) and trends toward higher levels of evidence (LOE) in the plastic surgery literature has been reported; however, there has not been a specific focus on the LOE of presentations at scientific meetings. The purpose of this study was to ascertain trends in the LOE of studies presented at the annual meeting of the American Association of Plastic Surgeons. METHODS: A hand search was conducted identifying all abstracts of podium presentations from 2009 to 2019. LOE, using American Society of Plastic Surgeons guidelines, were ascribed to each presentation, along with identification of any corresponding journal publications. RCTs were further analyzed using the 12-item Modified Consolidated Standard of Reporting Trials checklist. RESULTS: Four hundred forty-one studies with a median LOE of 3 were included in the study. A non-significant improvement in the mean level of evidence was noted over time (P = 0.09) along with an increase in the number of level 2 studies (P = 0.589) and RCTs (P = 0.717). Level 1 studies were rare (0.91%) and of fair quality (median checklist score 8 out of 12). Seventy-two percent of abstracts resulted in publication, and the mean lag time to publication was 422 days. CONCLUSIONS: A favorable trend is observed with respect to the mean LOE as well as the number of level 2 studies and RCTs over time. The importance of research meeting attendance to maintain up-to-date information is noteworthy, given the long lag time from presentation to publication.

The Impact of Premastectomy Versus Postmastectomy Radiation Therapy on Outcomes in Prepectoral Implant-Based Breast Reconstruction.

PURPOSE: Prepectoral implant-based breast reconstruction is being increasingly performed over subpectoral reconstruction because of the reduced invasiveness of the procedure, postoperative pain, and risk of animation deformity. Radiation therapy is a well-known risk factor for complications in implant-based breast reconstruction. The effect of premastectomy versus postmastectomy radiation therapy on outcomes after prepectoral breast reconstruction has not been well-defined. The purpose of this study was to compare the impact of premastectomy versus postmastectomy radiation therapy on outcomes after prepectoral breast reconstruction. METHODS: A retrospective chart review was performed on all patients who underwent prepectoral implant-based breast reconstruction with inferior dermal flap and acellular dermal matrix performed by a single surgeon from 2010 to 2019. Demographic, clinical and operative data were reviewed and recorded. Outcomes were assessed by comparing rates of capsular contracture, infection, seroma, hematoma, dehiscence, mastectomy skin flap necrosis, rippling, implant loss, local recurrence and metastatic disease, between patients receiving premastectomy and postmastectomy radiation therapy and nonradiated patients. RESULTS: Three hundred and sixty-nine patients (592 breasts) underwent prepectoral implant-based breast reconstruction. Twenty-six patients (28 breasts) received premastectomy radiation, 45 patients (71 breasts) received postmastectomy radiation, and 305 patients (493 breasts) did not receive radiation therapy. Patients with premastectomy radiation had higher rates of seroma (14.3% vs 0.2%), minor infection (10.7% vs 1.2%), implant loss (21.4% vs 3.4%) and local recurrence (7.1% vs 1.0%), compared with nonradiated patients (P < 0.05). Patients with postmastectomy radiation had higher rates of major infection (8.4% vs 2.4%), capsular contracture (19.7% vs 3.2%), implant loss (9.9% vs 3.4%), and local recurrence (5.6% vs 1.0%) when compared with nonradiated patients (P < 0.03). Outcomes after prepectoral breast reconstruction were comparable between premastectomy and postmastectomy radiation patients, respectively, with regard to major infection (7.1% vs 8.4%), dehiscence (3.6% vs 1.4%), major mastectomy skin flap necrosis (7.1% vs 2.8%), capsular contracture (10.7% vs 19.7%), implant loss (21.4% vs 9.9%), and local recurrence (7.1% vs 5.6%) (P ≥ 0.184). However, premastectomy radiation patients had a higher rate of seroma compared with postmastectomy radiation patients (14.3% vs 0%; P = 0.005). CONCLUSIONS: In prepectoral implant breast reconstruction, premastectomy and postmastectomy radiation therapy were associated with higher rates of infection and implant loss compared with nonradiated patients. Postmastectomy radiation was associated with a higher rate of capsular contracture compared with nonradiated patients, and a comparable rate of capsular contracture compared with premastectomy radiation therapy patients. Premastectomy radiation was associated with a higher rate of seroma compared with postmastectomy radiation and nonradiated patients.

Long-Term Neurocognitive Outcomes of Spring-Assisted Surgery versus Cranial Vault Remodeling for Sagittal Synostosis.

BACKGROUND: A long-term neurocognitive comparison of patients with sagittal synostosis who underwent spring-assisted surgery or cranial vault remodeling has not been performed. METHODS: Patients with sagittal synostosis who underwent spring-assisted surgery or cranial vault remodeling were recruited from Wake Forest School of Medicine and Yale School of Medicine, respectively. Cognitive tests administered included an abbreviated intelligence quotient, academic achievement, and visuomotor integration. An analysis of covariance model compared cohorts controlling for demographic variables. RESULTS: Thirty-nine spring-assisted surgery and 36 cranial vault remodeling patients were included in the study. No significant differences between cohorts were found with respect to age at surgery, sex, race, birth weight, family income, or parental education. The cranial vault cohort had significantly older parental age (p < 0.001), and mean age at testing for the spring cohort was significantly higher (p = 0.001). After adjusting for covariates, the cranial vault cohort had significantly higher verbal intelligence quotient (116.5 versus 104.3; p = 0.0024), performance intelligence quotient (109.2 versus 101.5; p = 0.041), and full-scale intelligence quotient (114.3 versus 103.2; p = 0.0032). When included patients were limited to intelligence quotients from 80 to 120, the cranial vault cohort maintained higher verbal (108.0 versus 100.4; p = 0.036), performance (104.5 versus 97.7; p = 0.016), and full-scale (107.6 versus 101.5; p = 0.038) intelligence quotients. The cranial vault cohort had higher visuomotor integration scores than the surgery group (111.1 versus 98.1; p < 0.001). There were no significant differences in academic achievement. CONCLUSIONS: Sagittal synostosis patients who underwent cranial vault remodeling had higher intelligence quotient and visuomotor integration scores. There were no differences in academic achievement. Both cohorts had intelligence quotient scores at or above the normal range. Further studies are warranted to identify factors that may contribute to cognitive outcome differences.

Primary Cleft Palate Repair Among Older-Age Children and Adolescents in the United States.

PURPOSE: Older age cleft palate (CP) repair in international settings has been associated with increased surgical morbidity. This study assesses the prevalence and risks associated with late-age CP repair (age > 5 years) in the United States. METHODS: Primary CP repair patients less than the age of 18 years were identified in the National Surgical Quality Improvement pediatric database from 2012 to 2018. Total postoperative complications, readmissions, reoperations, duration of surgery, and length of stay were recorded. T-tests and χ2 analyses were used to compare variables between age groups 0-5, 6-10, and 11-17. RESULTS: A total of 10,022 primary CP procedures were identified from 2012 to 2018, of which 868 (8.6%) received repair at age > 5 years. Hispanic patients constituted a larger proportion of CP repair from ages 11 to 17 years than repair at other ages (P < .001). In comparison with children treated from ages 0 to 5 years, children operated on between ages 6 and 10 or 11 and 17 years experienced no increases in unplanned readmissions, reoperations, or complication rates after surgery. Patients of ages 6-10 years and 11-17 years had decreased operating room time (P < .001) compared with younger patients. Patients of ages 11-17 years also had decreased hospital length of stay (P = .04). CONCLUSIONS: Many children in the United States received primary CP repair after the age of 5 years likely due to late treatment of submucosal clefts or delayed care among international immigrants/adoptees. Old age procedures were not associated with increased short-term surgical morbidity in comparison with surgery at earlier time points. The causes and implications of older age primary surgery warrant further study.

Long-Term Neurocognitive Outcomes in Sagittal Synostosis: The Impact of Reoperation.

INTRODUCTION: Optimal age at surgery in nonsyndromic sagittal craniosynostosis continues to be debated. Previous reports suggest that earlier age at whole vault cranioplasty more frequently requires reoperation. It is unknown, however, whether reoperation affects neurocognitive outcome. This study examined the impact of reoperation on neurocognitive outcome in children with nonsyndromic sagittal craniosynostosis using comprehensive neurocognitive testing. METHODS: Forty-seven school-age children (age 5-16 years) with nonsyndromic sagittal craniosynostosis who underwent whole-vault cranioplasty were included in this analysis. Participants were administered a battery of standardized neuropsychological testing to measure neurocognitive outcomes. RESULTS: Thirteen of the 47 participants underwent reoperation (27.7%); 11 out of the 13 reoperations were minor revisions while 2 reoperations were cranioplasties. Reoperation rate was not statistically different between patients who had earlier surgery (at age ≤6 months) versus later surgery (at age >6 months) (P > 0.05). Nonreoperated patients who had only one later-in-life surgery did not perform statistically better than reoperated patients on any outcome measure of neurocognitive function, including IQ, academic achievement, visuomotor integration, executive function, and behavior. Comparing reoperated earlier surgery patients with nonreoperated later surgery patients, reoperated earlier surgery patients had higher full-scale and verbal IQ (P < 0.05), scored higher on word reading, reading comprehension, spelling, numerical operations, and visuomotor integration (P < 0.05), and had fewer indicators of suspected learning disabilities (P < 0.01) compared to nonreoperated later surgery patients. CONCLUSION: Reoperation rate after whole vault cranioplasty was 27.7%, with few cases of repeat cranioplasty (4.2% of all patients). Reoperation was not associated with worse neurocognitive outcome. Reoperated earlier surgery patients in fact performed better in IQ, academic achievement and visuomotor integration when compared to nonreoperated later surgery patients.

Neurologic Characterization of Craniosynostosis: Can Direct Brain Recordings Predict Language Development?

PURPOSE: Nonsyndromic craniosynostosis (NSC) is associated with language deficits. Conventional tests, such as the Bayley Scales of Infant Development (BSID), may not reflect accurate long-term cognition. Alternatively, mismatch negativity (MMN) waves recorded via electroencephalogram (EEG) measure neural responses to speech and may objectively predict language development. This study aimed to (1) correlate infant MMN to future language achievement and (2) compare MMN among subtypes of NSC. METHODS: Pre and postoperatively (mean operative age 9.5 months), NSC participants received the BSID and EEG phoneme-discrimination paradigm(80 dB,250 Hz). The MMN was the largest negative amplitude in the difference wave 80 to 300 ms after stimuli. To measure cognitive outcome, patients completed a neurodevelopmental battery (Wechsler-Abbreviated Scale of Intelligence and Wechsler-Fundamentals) at >6 years of age. RESULTS: Eleven NSC patients with EEG testing in infancy were neurocognitively tested (average age 8.0 years; 27% female; 55% sagittal, 27% metopic, 9% unicoronal, 9% sagittal/metopic). The left frontal cluster MMN strongly correlated with word-reading (r = 0.713, P = 0.031), reading-comprehension (r = 0.745, P = 0.021), and language-composites (r = 0.0771, P = 0.015). Conversely, BSID scores did not yield significant predictive value (r < 0.5, P > 0.05). Follow-up event related potentials (ERP) comparison included 39 normal control, 18 sagittal, 17 metopic, 6 unilateral-coronal infants. Preoperatively, sagittal (P = 0.003) and metopic (P = 0.003) patients had attenuated left frontal MMN compared to controls. Postoperatively, the sagittal cohort was normalized to controls while metopic patients retained attenuations (P = 0.041). CONCLUSION: ERP assessment in NSC had significantly better predictive value for future neurocognition than the BSID. Preoperatively, sagittal and metopic patients had attenuated neural response to language; postoperatively, sagittal patients had improved responses in comparison to metopic patients. Use of ERP assessment may help tailor treatment for language deficits earlier in development.

The Effect of Surgical Timing on 30-Day Outcomes in Cleft Palate Repair.

BACKGROUND: The optimal age for cleft palate repair continues to be debated, with little discussion of surgical risk related to operative timing. This study of 3088 cleft palate patients analyzed the impact of surgical timing on perioperative and 30-day postoperative outcomes. METHODS: Primary cleft palate repairs were identified in the National Surgical Quality Improvement Program database from 2012 to 2015. Data were combed for total postoperative complications, rates of readmission and reoperation, operating room time, and length of stay. Bivariate analyses were performed comparing 3-month periods from months 6 to 18, and months 0 to 5, 18 to 23, 24 to 29, and 30 to 59. RESULTS: Despite a higher proportion of isolated soft palate closure, children operated on before 6 months had a higher complication rate than children at other ages (7.1 percent versus 3.2 percent; OR, 2.4; p = 0.04), and higher rates of both readmission (3.6 percent versus 1.4 percent; OR, 3.6; p = 0.02) and reoperation (2.4 percent versus 0.5 percent; OR, 4.7; p = 0.04). There were no differences in short-term outcomes for any other age group younger than 5 years, and no differences in hospital length of stay among any age groups. CONCLUSIONS: The authors' findings suggest a relative contraindication to operation before 6 months. As there were no differences between any other age groups, long-term speech optimization should continue to be the primary consideration for operative planning. These findings improve the current rationale for palatoplasty timing, and can aid surgeons and parents in the surgical decision-making process. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Spring-Assisted Strip Craniectomy Versus Cranial Vault Remodeling: Long-Term Psychological, Behavioral, and Executive Function Outcomes.

BACKGROUND: Controversy exists regarding the optimal surgical approach for non-syndromic sagittal synostosis. This study provides the first comparative analysis of the long-term behavioral, psychological, and executive function outcomes for patients who underwent either cranial vault remodeling (CVR) or spring-assisted strip craniectomy (SAS). METHODS: Thirty-six CVR patients and 39 SAS patients were evaluated. Parents and caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF) and the Behavior Assessment System for Children, Second Edition (BASC-2) to evaluate behavioral, emotional, social, adaptive, and executive functioning skills. RESULTS: There were no statistically significant differences between the CVR and the SAS groups (P > 0.05) in any of the BRIEF areas of function. Furthermore, the BASC-2 battery illustrated no significant differences in all areas analyzed except one. Among the 2 groups, the CVR group was rated as having fewer social withdrawal symptoms on the BASC-2 (47.00 ±â€Š10.27) compared to the SAS cohort (54.64 ±â€Š10.96), F = 6.79, P = 0.012, Cohen d = 0.688. However, both means were still within the normal range. CONCLUSIONS: Children undergoing SAS and CVR procedures for isolated sagittal synostosis were not rated as having clinically significant behavioral, emotional, social, adaptive, or executive functioning problems on parental forms.
