Apert syndrome: neurosurgical outcomes and complications following posterior vault distraction osteogenesis.

PURPOSE: Posterior vault distraction osteogenesis (PVDO) has been utilized during the past 15 years to treat a variety of clinical features commonly presented by patients with Apert syndrome. The objective of this study is to determine the efficacy of PVDO in addressing both elevated intracranial pressure (ICP) and ectopia of the cerebellar tonsils (ECT) in young Apert patients. In addition, we aimed to determine the prevalence of hydrocephalus in Apert syndrome patients who underwent PVDO. METHODS: A retrospective study was made with a cohort of 40 consecutive patients with syndromic craniosynostosis (SC), previously diagnosed with Apert syndrome, who underwent PVDO between 2012 and 2022, and thereafter received at least 1 year of follow-up care. Demographic data and diagnosis, along with surgical and outcome data, were verified using medical records, clinical photographs, radiologic examination, and interviews with the parents of all cohort patients. RESULTS: The average patient age when PVDO was performed was 12.91 ± 10 months. The average posterior advancement distance achieved per patient was 22.68 ± 5.26 mm. The average hospital stay per patient was 3.56 ± 2.44 days. The average absolute and relative blood transfusion volumes were 98.47 ml and 17.63 ml/kg, respectively. Although five patients (14%) presented ECT preoperatively, this condition was completely resolved by PVDO in three of these five patients. One of the three patients whose ECT had completely resolved presented syringomyelia postoperatively, requiring subsequent extra dural foramen magnum decompression. All of the remaining four patients were asymptomatic for ECT for at least 1 year of follow-up, and none of these four patients required any additional treatments to address ECT. Two patients presented hydrocephalus requiring ventriculoperitoneal shunt placement. CONCLUSIONS: This study demonstrates that PVDO both reduces diagnosed elevated ICP symptoms and is partially effective in treating ECT in Apert syndrome patients. Hydrocephalus in Apert syndrome is an uncommon feature. The effectiveness of PVDO in addressing hydrocephalus is uncertain.

Apert Syndrome: Selection Rationale for Midface Advancement Technique.

Apert syndrome is characterized by a wide spectrum of craniofacial clinical features that have been successfully addressed via a variety of midface advancement techniques. Although surgeons have individual preferences as to which specific procedures should be performed to best treat Apert patients, craniofacial plastic surgeons, working in tandem with pediatric neurosurgeons, can identify and evaluate functional limitations and facial morphologic disproportions, and establish appropriate criteria for effective midface advancement technique indication and selection. The purpose of this review article is to present and discuss our rationale for midface advancement technique selection based upon the most common craniofacial characteristics presented by Apert syndrome patients. The present article also provides a grading system that stratifies as major, moderate, and mild, the effect of each midface advancement technique on the different types of Apert syndrome facial features. Surgeons should take into consideration the maximum effect and benefit of each craniofacial osteotomy and how these procedures will alter the craniofacial skeleton. By understanding the long-term effect of each osteotomy on the most common craniofacial characteristics of Apert syndrome patients, craniofacial plastic surgeons and neurosurgeons will be able to customize the surgical procedures they perform in order to achieve the best possible outcomes.

Growing skull fracture in a child with Ehlers-Danlos syndrome: case report and literature review.

INTRODUCTION: Growing skull fracture (GSF) is a rare complication of head trauma in the pediatric population, commonly observed in children younger than 3 years. DISCUSSION: In this report, the authors describe a case of a 3-year-old male child, with clinical features of Ehlers-Danlos syndrome (EDS), who developed a GSF in frontal bone after a crib fall, treated with duraplasty and cranioplasty with autologous craft. Here, pertinent literature was reviewed with an emphasis on surgical techniques, and correlation with the mentioned syndrome. CONCLUSION: This is the first case of GSF in association with EDS in the literature. The relevance of the case described concerns the rarity of the condition itself, the atypical presentation, and the intraoperative findings, which showed the important fragility of the dura mater, probably due to EDS. Therefore, this syndrome, besides having influenced the pathogenesis, was also a challenging factor in the surgical treatment.

Characterization of enamel developmental defects in patients with orofacial clefts and their relationship to surgical procedures.

AIMS: This study aimed to characterize the prevalence of development defects of enamel (DDE) in patients with cleft based on the cleft phenotype and explore the relationship between surgical procedures and different types of DDE. MATERIAL AND METHODS: In this cross-sectional study, 290 standardized orthodontic documentation and medical records from a reference hospital were evaluated, which treated patients with: cleft lip (CL), cleft lip with alveolar bone involvement (CLa), cleft lip and palate (CLP), cleft palate (CP), cleft median (CM), and considering laterality as unilateral or bilateral. DDE was assessed using the Ghanim Index (2015). Information on surgical intervention periods was obtained from medical records. Statistical analyses were performed using prevalence ratio (PR) for DDE comparisons between cleft phenotypes and surgical procedures. RESULTS: The prevalence of DDE was 77.2%. Demarcated hypomineralization was associated with CP and CLP, while hypoplasia was associated with CLa, especially when bilateral. Hypoplasia was also associated with the labial adhesion surgery. CONCLUSION: Demarcated hypomineralization was the most common DDE in this population, and the cleft phenotype influenced the type of DDE manifested. The lip adhesion surgery increased the chances of hypoplasia manifestation. CLINICAL RELEVANCE: The type of DDE in patients with cleft depends on the cleft phenotype. Understanding this susceptibility enables the multidisciplinary team to monitor dental development, thus allowing early diagnosis and timely referral to the pediatric dentist and better prognoses.

Outcomes of Apert Syndrome Hand Reconstruction With Tilapia Skin: A Prospective Study.

BACKGROUND: Tilapia skin has already been used in various medical scenarios, but there are no studies showing the use of tilapia skin for hand reconstruction in Apert syndrome. The objective of this study is to determine whether the use of tilapia skin during graft bed preparation for children with Apert syndrome can shorten wound reepithelialization intervals, reduce the number of dressing changes, and decrease patient discomfort. METHODS: This is a prospective study on consecutive patients with Apert syndrome who underwent hand reconstruction at our Hospital. Patients were divided into 2 groups: (1) a control group consisting of patients who underwent conventional digit separation hand reconstruction surgery (2) an experimental group consisting of patients who underwent similar digit separation hand reconstruction surgery that commenced with the placement of a thin layer of tilapia skin at the raw commissures during a first operation, which was subsequently replaced by an autologous skin graft during a second operation staged 10 days postoperatively. Pain assessment was performed using the Visual Analog Scale. The number of dressing changes was also assessed. A T test compared the total number of dressings changes and pain data. RESULTS: Experimental group patients (n = 8) required an average of 9.4 days of daily dressing changes, and control group patients (n = 5) required an average of 20.8 days of daily dressing changes ( P < 0.05) and tended to experience significantly less pain when compared with patients in the control group ( P = 0.079). CONCLUSION: Tilapia skin can shorten wound reepithelialization intervals by reducing the total number of dressing changes.

The First Hybrid International Educational Comprehensive Cleft Care Workshop.

OBJECTIVE: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN: Cross-sectional survey-based evaluation. SETTING: International comprehensive cleft care workshop. PARTICIPANTS: Total of 489 participants. INTERVENTIONS: Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

Apert Syndrome Outcomes: Comparison of Posterior Vault Distraction Osteogenesis Versus Fronto Orbital Advancement.

BACKGROUND: Presenting a wide clinical spectrum and large variety of clinical features, successful treatment of Apert syndrome necessitates performance of sequential multiple surgeries before a patient's facial skeleton growth is complete.The objective of this study is to compare forehead contour asymmetry and clinical outcomes between Apert patients who underwent either fronto-orbital advancement (FOA) or posterior vault distraction osteogenesis (PVDO). METHODS: A retrospective study was performed on consecutive patients with Apert syndrome who underwent either FOA or PVDO between 2007 and 2019, and participated in at least 6 months of follow-up care. Forehead contour asymmetry and surgical outcomes for each of the included patients were verified through medical records, clinical photographs, and interviews with the parents of the patients. The need for additional craniofacial procedures based on the surgical outcomes of each patient was graded from I to IV utilizing the Whitaker outcome classification system. RESULTS: Forehead contour asymmetry for all included patients was rated under the Whitaker grading scale as type II (n = 4) 44.4%, type III (n = 2) 22.2%, and type IV (n = 3) 33.3% for FOA, and type I (n = 5) 35.7%, type II (n = 7) 50%, and type III (n = 2) 14.3%, for PVDO (P < 0.05). The average transfused blood volume was 47.77 ±â€Š9.42 mL/kg for patients who underwent FOA, and 22.75 ±â€Š10.31 mL/kg for patients who underwent PVDO (P < 0.05). CONCLUSIONS: Patients who underwent PVDO had lower forehead contour asymmetry as per the Whitaker outcome grading scale than patients who underwent FOA.

Posterior Vault Distraction Outcomes in Patients With Severe Crouzon Syndrome Resulting from Ser347Cys and Ser354Cys Mutations.

BACKGROUND: In this study, the authors present the outcomes of 4 patients with a severe form of Crouzon syndrome characterized by mutation of fibroblast growth factor receptor 2 (FGFR2) c.1040 C > G p.Ser347Cys or the pathogenic c.1061C > G p.Ser354Cys variant of FGFR2, who underwent posterior vault distraction osteogenesis (PVDO) to alleviate elevated intracranial pressure. METHODS: Patients with diagnosed Crouzon syndrome who were found by genetic testing to have an FGFR2 c.1040 C > G p.Ser347Cys mutation or the c.1061C > G p.Ser354Cys variant were included. Outcome data and presence of hydrocephalus, Chiari Malformation type I (CMIs), and the presence/absence of a tracheostomy were recorded. RESULTS: Three patients with the FGFR2 c.1040 C > G p.Ser347Cys mutation and 1 with the pathogenic FGFR2 c.1061C > G p.Ser354Cys variant were identified as having characteristics of severe Crouzon syndrome. The mean age at PVDO was 15 months and the mean posterior advancement was 20 mm. All 4 patients experienced sufficient relief of the elevated intracranial pressure from the PVDO to prevent the need for shunt placement, stabilize the ventricular dimensions (n = 2), and resolve the CMIs (n = 2). Intracranial pressure screening ruled out malignant cerebrospinal fluid volume increase. CONCLUSIONS: PVDO effectively prevented hydrocephalus and resolved CMIs, successfully alleviating intracranial pressure and maximizing clinical outcomes for patients with severe Crouzon syndrome.

Functionality Assessment of Patients With Cleft Hands.

BACKGROUND: Ectrodactyly, commonly referred to as cleft hand, is a rare pathology characterized by a deficiency and/or complete absence of the central ray in each hand. In order to customize treatment and improve the patient's quality of life, a more detailed functional evaluation is required. Although several studies evaluate functionality in different types of cleft hands, there are only a few studies that show self-reported evaluations. The objective of this study is to assess the hand function of cleft hand patients. METHODS: An observational retrospective study was performed on 12 cleft hand patients who were treated between 2008 and 2018. There were 8 male patients and 4 female patients. Patients were divided into 2 groups according to their ages: (Group 1) 6 patients between 1 and 7 years of age, and (Group 2) 6 patients between 8 and 18 years of age, respectively. Each group was sub-stratified into 5 subgroups according to the classification system created by Manske and Halikis. RESULTS: Regardless of age, intragroup hand type comparisons within Groups 1 and 2 did not demonstrate statistically significant differences (P > 0.05) between hand outcomes according to Manske and Halikis classification. Comparison between cleft hand patients and their age matched controls demonstrated statistically significant differences (P < 0.05), as the patients in the control group had higher outcome scores. CONCLUSIONS: Regardless of cleft hand type and patient age, patients with cleft hands experience impaired hand function and present lower outcome scores in comparison to their age matched controls.

Syndrome-related outcomes following posterior vault distraction osteogenesis.

PURPOSE: The most commonly occurring syndromic craniosynostoses are Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, and Saethre-Chotzen syndrome. There is insufficient data regarding postoperative syndrome-related outcomes following the posterior vault distraction osteogenesis (PVDO) procedure, as well as data addressing whether or not additional procedures will be subsequently necessary to comprehensively treat children who undergo PVDO. Thus, the objective of this study is to describe and compare syndrome-related potential complications and outcomes associated with the PVDO procedure. METHODS: An observational retrospective study was performed on consecutive patients (n=24) with Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, or Saethre-Chotzen syndrome, respectively, who underwent PVDO between 2012 and 2019. Demographic data (patient gender and age when the PVDO procedure was performed), diagnosis, surgery-related data, and outcome data (perioperative and midterm complications and need for additional surgery) were verified. RESULTS: Total relative blood transfusion volumes per kilogram for the patients were as follows: 22.75 ± 9.30 ml for Apert syndrome, 10.73 ± 2.28 ml for Crouzon syndrome (Apert versus Crouzon, p<0.05), 18.53 ± 8.08 ml for Pfeiffer syndrome, and 19.74 ± 9.12 ml for Saethre-Chotzen syndrome. None of the patients required a secondary procedure to alleviate intracranial pressure except for a Saethre-Chotzen patient. CONCLUSION: PVDO is an effective technique to address elevated intracranial pressure in SC patients that alleviates the need for secondary procedures at midterm follow-up. Apert syndrome patients presented relatively higher total blood transfusion rates than Crouzon syndrome patients who were operated on at a later age and weighed more.

Craniofrontonasal dysplasia: hypertelorism correction in late presenting patients.

BACKGROUND: Craniofrontonasal dysplasia (CFND) is a rare congenital craniofacial syndrome characterized by single suture synostosis, hypertelorism, other clinical facial features, and abnormalities in the upper extremities. There are only a few studies in the applicable literature that address hypertelorism management for CFND patients and outcomes and complication rates. METHODS: A retrospective study was performed on consecutive late presenting CFND patients referred to our hospital with substantially completed craniofacial skeleton growth, who underwent hypertelorism correction between 2007 and 2019 following intracranial pressure screening, and who received at least 1 year of follow-up care. None of the patients in this study underwent prior craniofacial surgery. Only those patients with a confirmed mutation of the EFNB1 gene were included in this study. All patients in this study underwent hypertelorism correction by facial bipartition or box osteotomy. RESULTS: A total of ten late presenting CFND patients (all female) were treated at our hospital during the study period. None of the patients presented signs of elevated intracranial pressure. The average patient age at hypertelorism correction was 13.4 ± 7.68 years of age. Major complications, defined as complications requiring a return to the operating room, were limited to infection of the frontal bone, which required partial bone removal, and cerebrospinal fluid (CSF) leak, which was completely resolved by insertion of a lumbar shunt for a 7-day period. CONCLUSION: The absence of elevated intracranial pressure enables hypertelorism correction in late presenting CFND patients via facial bipartition or box osteotomy without the need for additional operations that provide for cranial expansion.

Severe craniolacunae and upper and lower extremity anomalies resulting from Crouzon syndrome, FGFR2 mutation, and Ser347Cys variant.

Crouzon syndrome is a rare form of syndromic craniosynostosis (SC) characterized by premature fusion of the cranial and facial sutures, elevated intracranial pressure, varying degrees of ocular exposure due to exorbitism, and airway compromise caused by midface retrusion. Craniolacunae and upper and lower extremity anomalies are not frequently found in Crouzon syndrome. We present a girl with Crouzon syndrome caused by c.1040 C > G, p.Ser347Cys, a pathogenic mutation in the FGFR2 gene with atypical characteristics, including craniolacunae resembling severe Swiss cheese type of bone formation, and upper and lower extremity anomalies which are more commonly associated with Pfeiffer syndrome patients. Distinguishing between severe Crouzon syndrome patients and patients who have mild and/or moderate Pfeiffer syndrome can be challenging even for an experienced craniofacial surgeon. An accurate genotype diagnosis is essential to distinguishing between these syndromes, as it provides predictors for neurosurgical complications and facilitates appropriate family counseling related to long-term outcomes.

An Extended 45-year Long-term Follow-up on a 1-13 Rare Facial Cleft Patient.

ABSTRACT: We present here the unique case of a patient with a Tessier 1-13 rare facial cleft accompanied by cleft lip and palate and Tessier grade 2 hypertelorism. The patient described in this article has a twin brother who shares a number of genetic traits and physical features but does not present facial cleft or hypertelorism. The 45-year follow-up in this case is believed to be the longest follow-up to date to have been reported in the literature, and sheds significant light on the importance of extended longitudinal follow-up to maximize patient outcomes.

Apert Hand Reconstruction: Do Partial-Thickness Skin Grafts Result in Flexion Scar Contracture?

BACKGROUND: Hand reconstruction for patients with Apert syndrome is a critical step in comprehensive care and enables this population to gain significant hand function. Digit separation for Apert syndrome, as described in most algorithms, is finalized using local flaps and full-thickness skin grafts. The objective of this study is to report our experience using local flaps and partial-thickness skin grafts after digit separation for Apert hand reconstruction. METHODS: An observational retrospective study was performed with Apert patients whose hands were reconstructed between January 2007 and July 2019 using local flaps and partial-thickness skin grafts after digit separation. Demographic data and outcome data were verified and recorded. RESULTS: Out of a total of 75 Apert patients who underwent hand reconstruction, 12 underwent hand reconstruction utilizing local flaps and partial-thickness skin grafts. The average patient age at the time of the first procedure was 1.9 years. These 12 patients were stratified according to Upton hand severity, 3 being type I (25%), 3 being type II (25%) and 6 being type III (50%). Mean follow up provided to all patients in this study was 1.8 years and donor site-related complications were seen in 2 patients (16.6%). No flexion scar contracture was observed in any of the patients who received partial-thickness skin grafts. CONCLUSIONS: The use of local flaps along with partial-thickness skin grafts to finalize digit separation for patients with Apert syndrome is an effective technique that reduces donor site morbidity and does not result in flexion scar contracture.

Long-Term Morphologic Changes on Sagittal Synostosis Patients Who Underwent a Modified Pi Technique.

BACKGROUND: There are paucity of studies focused on the long-term assessment of the craniofacial changes after a pi-plasty procedure and self-reported quality of life outcomes. Thus, this study aimed to assess long-term morphologic changes and quality of life of patients with sagittal synostosis who underwent surgery with a modified pi-plasty. METHODS: Consecutive patients with sagittal synostosis who underwent surgery and had more than 5 years of follow-up and standard preoperative and 1, 3, and 5 years right profile view photographs were included. Nasofrontal angle and angle of total facial convexity were evaluated using computerized photogrammetric measurements. Additionally, quality of life outcome was evaluated by the Quality of Life Scale Short Form. RESULTS: The total facial convexity angle and nasofrontal angle increased significantly (P < 0.05), with a P-value of 0.013 and 0.012, respectively. Patients had quality of life scores >80 in all of the 4 domains, with the highest scores being: physical health domain 80.0 ±â€Š0, psychologic domain 85.0 ±â€Š5, social relationships domain 86.6 ± 0, and environmental domain 98.13 ±â€Š2.42. CONCLUSION: Facial angles significantly changed over 5 years of follow-up. Self-reported quality of life instrument showed that patients are satisfied with their own appearance, contributing positively to their quality of life.

Roberts Syndrome With a Bilateral Cleft Lip and Palate.

ABSTRACT: Roberts syndrome (RBS) is a rare craniofacial anomaly associated with tetraphocomelia, growth and mental retardation, cardiac and renal abnormalities. The RBS is caused by homozygous mutation in the ESCO2 gene on chromosome 8p21. In this report, the authors describe a 5-year-old female infant with RBS and bilateral cleft lip and cleft palate, an extremely rare condition.

Augmented reality and physical hybrid model simulation for preoperative planning of metopic craniosynostosis surgery.

OBJECTIVE: The main objective of neurosurgery is to establish safe and reliable surgical techniques. Medical technology has advanced during the 21st century, enabling the development of increasingly sophisticated tools for preoperative study that can be used by surgeons before performing surgery on an actual patient. Laser-printed models are a robust tool for improving surgical performance, planning an operative approach, and developing the skills and strategy to deal with uncommon and high-risk intraoperative difficulties. Practice with these models enhances the surgeon's understanding of 3D anatomy but has some limitations with regard to tactile perception. In this study, the authors aimed to develop a preoperative planning method that combines a hybrid model with augmented reality (AR) to enhance preparation for and planning of a specific surgical procedure, correction of metopic craniosynostosis, also known as trigonocephaly. METHODS: With the use of imaging data of an actual case patient who underwent surgical correction of metopic craniosynostosis, a physical hybrid model (for hands-on applications) and an AR app for a mobile device were created. The hybrid customized model was developed by using analysis of diagnostic CT imaging of a case patient with metopic craniosynostosis. Created from many different types of silicone, the physical model simulates anatomical conditions, allowing a multidisciplinary team to deal with different situations and to precisely determine the appropriate surgical approach. A real-time AR interface with the physical model was developed by using an AR app that enhances the anatomic aspects of the patient's skull. This method was used by 38 experienced surgeons (craniofacial plastic surgeons and neurosurgeons), who then responded to a questionnaire that evaluated the realism and utility of the hybrid AR simulation used in this method as a beneficial educational tool for teaching and preoperative planning in performing surgical metopic craniosynostosis correction. RESULTS: The authors developed a practice model for planning the surgical cranial remodeling used in the correction of metopic craniosynostosis. In the hybrid AR model, all aspects of the surgical procedure previously performed on the case patient were simulated: subcutaneous and subperiosteal dissection, skin incision, and skull remodeling with absorbable miniplates. The pre- and postoperative procedures were also carried out, which emphasizes the role of the AR app in the hybrid model. On the basis of the questionnaire, the hybrid AR tool was approved by the senior surgery team and considered adequate for educational purposes. Statistical analysis of the questionnaire responses also highlighted the potential for the use of the hybrid model in future applications. CONCLUSIONS: This new preoperative platform that combines physical and virtual models may represent an important method to improve multidisciplinary discussion in addition to being a powerful teaching tool. The hybrid model associated with the AR app provided an effective training environment, and it enhanced the teaching of surgical anatomy and operative strategies in a challenging neurosurgical procedure.

Upper Lip Fat Grafting Using the Anatomical Subunit and Fat Compartment Principles Improves Lip Cant and Symmetry in Patients With Unilateral Upper Lip Asymmetries.

BACKGROUND: Fat grafting is a widely adopted method for reconstructing upper lip asymmetries. However, most surgical techniques are difficult to reproduce, and none follow anatomical principles. OBJECTIVES: The aim of this study was to assess the clinical outcomes of upper lip contour asymmetry and lip cant correction by anatomical upper lip fat grafting using the subunit and fat compartment principles. METHODS: A prospective analysis was conducted of 113 consecutive patients who underwent anatomical upper lip fat grafting using the subunit and fat compartment principles for the management of lip cant and/or upper lip contour (volumetric) asymmetry. Quantitative photogrammetric upper lip symmetry and lip cant measurements were blindly performed preoperatively and at 3 and 12 months postoperatively. A panel assessment (by 8 blinded external plastic surgeons and 8 laypersons) was obtained to grade the qualitative upper lip symmetry. Bivariate and multivariate analyses were performed to identify independent variables associated with the 12-month postoperative lip cant change. RESULTS: There was significant (all P < 0.05) postoperative quantitative and qualitative upper lip symmetry and lip cant enhancement (preoperative < postoperative) after a single upper lip fat grafting procedure, and the outcomes were maintained (all P > 0.05) from 3 to 12 months postoperatively. Parry-Romberg syndrome was negatively associated (P < 0.05) with the 12-month postoperative lip cant change. CONCLUSIONS: Anatomical upper lip fat grafting, using the subunit and fat compartment principles, improves lip cant and symmetry in patients with unilateral upper lip asymmetries.

Apert Syndrome Management: Changing Treatment Algorithm.

BACKGROUND: The purpose of this study is to review 10 years of surgical experience in the management of Apert syndrome, focusing on an updated algorithm which includes hand reconstruction and posterior vault distraction osteogenesis (PVDO). Additionally, the authors compare PVDO, which is currently used, with fronto-orbital advancement (FOA), which was utilized in a previous algorithm. METHODS: An observational retrospective study was performed on consecutive patients with Apert syndrome who underwent upper and lower limb reconstruction and craniofacial surgery between 2007 and 2017. A modified Clavien-Dindo surgical complication scale was used to stratify complications between PVDO and FOA. Demographic, surgical, and outcome data was also recorded. The blood transfusion rate between PVDO and FOA was also assessed and compared utilizing the Student t test. RESULTS: The present study included 69 patients with Apert syndrome (34 males and 35 females). Craniofacial surgeries were performed on a total of 38 patients. A total of 210 operations were performed on the respective upper and lower limbs of patients included in this study. A total of 18 patients underwent PVDO (n = 9) and FOA (n = 9). Posterior vault distraction osteogenesis required significantly less transfused blood volume than FOA (P < 0.05). Complication rate and length of hospital stay were similar for each procedure. CONCLUSION: An updated algorithm to treat Apert patients was implemented. Posterior vault distraction osteogenesis incorporated into an updated algorithm results in a lower blood transfusion rate.

Outcomes of Surgical Management of Palatal Fistulae in Patients With Repaired Cleft Palate.

BACKGROUND: The palatal fistula is an important surgical challenge within the longitudinal follow-up of patients with repaired cleft palate as the success rate of palatal fistula reconstruction by adopting several surgical techniques is variable and often unsatisfactory. The purpose of this retrospective study was to report the clinical outcomes of an algorithm for the surgical management of palatal fistulae in patients with repaired cleft palate. METHODS: Consecutive patients (n = 101) with repaired cleft palate and palatal fistula-related symptoms who were treated according to a specific algorithm between 2009 and 2017 were included. Based on the anatomical location (Pittsburgh fistula types II-V), amount of scarring (minimal or severe scarred palate), and diameter of the fistula (≤5 mm or >5 mm), 1 of 3 approaches (local flaps [62.4%], buccinator myomucosal flaps [20.8%], or tongue flaps [16.8%]) was performed. For clinical outcome assessment, symptomatic and anatomical parameters (fistula-reported symptoms and residual fistula, respectively) were combined as follows: complete fistula closure with no symptoms; asymptomatic narrow fistula remained; or failure to repair the fistula ("good," "fair," or "poor" outcomes, respectively). Surgical-related complication data were also collected. RESULTS: Most patients (91.1%) presented "good" clinical outcomes, ranging from 86.2% to 100% (86.2%, 100%, and 100% for local flaps, buccinator flaps, and tongue flaps, respectively). All (8.9%) "fair" and "poor" outcomes were observed in fistulae reconstructed by local flaps. All "poor" (5%) outcomes were observed in borderline fistulae (4-5 mm). No surgical-related complications (dehiscence, infections, or necrosis) were observed, except for an episode of bleeding after the 1st stage of tongue flap-based reconstruction (1.0%). CONCLUSION: A high rate of fistula resolution was achieved using this algorithm for surgical management of palatal fistulae in patients with repaired cleft palate.
