Radiographic severity is associated with worse executive function in metopic craniosynostosis.

BACKGROUND: Children with metopic synostosis have been found to have more neurocognitive and behavioral difficulties. The variables that may affect future neurodevelopmental outcomes, including presenting morphologic severity, have not been fully studied. In the largest study to date, we aimed to assess what portends worse neurocognitive and behavioral outcomes at school age. METHODS: Children 6-18 years old with surgically corrected metopic nonsyndromic craniosynostosis underwent neurocognitive testing. Parents completed behavior rating surveys about their child: Conners-3 (ADHD), Social Responsiveness Scale-2 (autism spectrum disorder), Behavior Rating Inventory of Executive Function-2 (BRIEF-2: executive function), and Child's Behavior Checklist (overall behavior). The endocranial bifrontal angle (EBA), adjusted EBA (aEBA), frontal angle (FA), and AI-derived metopic severity score (MSS) were determined on pre-operative CT images. Multivariate linear regressions were used to evaluate the association of age at surgery and severity. RESULTS: There were 87 children who underwent neurocognitive testing (average age 10.9 ± 3.3 years) of whom 67 also completed behavioral assessments. Greater phenotypical severity of metopic synostosis (lower FA, aEBA, and EBA) was associated with worse scores on the subscales of the BRIEF-2 (executive function) and executive subscale of the Conners-3. Increasing age at surgery was associated with worse executive function subscale scores of the Conners-3 when controlling for each severity measurement and sociodemographic risk. CONCLUSION: Children with greater phenotypic severity of metopic synostosis have worse executive function at school age. The majority of children with metopic synostosis have signs of ADHD. Later surgeries (greater than 12 months) may impact executive functioning, regardless of the degree of severity. Future research should aim at identifying the direct structural changes to the brain.

ImageAssist: A Novel Smartphone Application for Standardized Clinical Photography That Implements and Automates American Society of Plastic Surgery/Plastic Surgery Foundation Photographic Guidelines With Background Deletion.

STATEMENT OF THE PROBLEM: Standardized medical photography of the face is a vital part of patient documentation, clinical evaluation, and scholarly dissemination. Because digital photography is a mainstay in clinical care, there is a critical need for an easy-to-use mobile device application that could assist users in taking a standardized clinical photograph. ImageAssist was developed to answer this need. The mobile application is integrated into the electronic medical record (EMR); it implements and automates American Society of Plastic Surgery/Plastic Surgery Research Foundation photographic guidelines with background deletion. INITIAL PRODUCT DEVELOPMENT: A team consisting of a craniofacial plastic surgeon and the Health Information Technology product group developed and implemented the pilot application of ImageAssist. The application launches directly from patients' chart in the mobile version of the EMR, EPIC Haiku (Verona, Wisconsin). Standard views of the face (90-degree, oblique left and right, front and basal view) were built into digital templates and are user selected. Red digital frames overlay the patients' face on the screen and turn green once standardized alignment is achieved, prompting the user to capture. The background is then digitally subtracted to a standard blue, and the photograph is not stored on the user's phone. EARLY USER EXPERIENCE: ImageAssist initial beta user group was limited to 13 providers across dermatology, ENT, and plastic surgery. A mix of physicians, advanced practice providers, and nurses was included to pilot the application in the outpatient clinic setting using Image Assist on their smart phone. After using the app, an internal survey was used to gain feedback on the user experience. In the first 2 years of use, 31 users have taken more than 3400 photographs in more than 800 clinical encounters. Since initial release, automated background deletion also has been functional for any anatomic area. CONCLUSIONS: ImageAssist is a novel smartphone application that standardizes clinical photography and integrated into the EMR, which could save both time and expense for clinicians seeking to take consistent clinical images. Future steps include continued refinement of current image capture functionality and development of a stand-alone mobile device application.

Surgical Complexity and Physician Workload in Craniofacial Surgery: Do RVUs Need to be Adjusted?

RVU valuations need to be revisited regularly as procedure complexity and patient care pathways continue to evolve. The NSQIP-P database was queried for craniofacial procedures performed in North America between 2012 and 2019. Multivariate regression was performed to determine correlation coefficients of perioperative variables deemed to reflect procedure severity, including procedure duration, blood transfusion, length of stay, serious adverse events, related readmission, and related reoperation. CPT 21159 Le Fort III with forehead advancement remains the craniofacial procedure with the highest RVUs using our model at 33.93 units. The most underestimated procedure is CPT 42235 Repair of anterior palate, including vomer flap, with a suggested change of +8.27 units, which is a 194% increase from current compensation. Adjusted RVUs based on quantitative and nationally representative perioperative variables that reflect procedure severity might be a better alternative for procedure valuation over current survey methods to determine appropriate insurance compensation.

Complete Extensive Heterotopic Ossification of the Entire Free Fibula Flap Vascular Pedicle in Maxillary Reconstruction.

INTRODUCTION: Heterotopic ossification is a pathologic extra-skeletal bone formation as a form of aberrant repair process with acquired or genetic etiologies. In plastic surgery, it has been well-described in the burn and trauma patients. Rarely, it can happen along the vascular pedicle of free tissue transfer, and when it happens, it is most commonly in head and neck reconstruction. CASE PRESENTATION: Here we present a case of complete extensive heterotopic ossification of the entire vascular pedicle from the anastomosis to the bone in an osteocutaneous free fibula flap (FFF). The fibula was used as a 2-segment reconstruction for a maxillary defect resulting from a self-inflicted gunshot wound. The skin paddle was used to reconstruct the anterior palatal defect. DISCUSSION: Heterotopic ossification of the FFF vascular pedicle is most reported in the head and neck reconstruction cases. It is rare, but when it happens, it occurs earlier, more commonly, and more extensively in cases of maxillary reconstruction than in cases of mandibular reconstruction. Flap loss due to this sequela has not been reported, and surgical debridement is indicated only when symptomatic. CONCLUSION: Heterotopic ossification of an FFF vascular pedicle is a rare but well-described entity. The periosteal bone formation capacity preservation after revascularization of the flap is thought to be one of the major etiologies of this phenomenon. Hence, some have suggested a modification in the harvesting technique of the FFF that could mitigate return to the operating room, especially when it is for maxillary reconstruction in the trauma patient. Keywords: Keywords: free fibula flap, heterotopic ossification, maxillary reconstruction, mandibular reconstruction.

Machine Learning for Automatic Detection of Velopharyngeal Dysfunction: A Preliminary Report.

BACKGROUND: Even after palatoplasty, the incidence of velopharyngeal dysfunction (VPD) can reach 30%; however, these estimates arise from high-income countries (HICs) where speech-language pathologists (SLP) are part of standardized cleft teams. The VPD burden in low- and middle-income countries (LMICs) is unknown. This study aims to develop a machine-learning model that can detect the presence of VPD using audio samples alone. METHODS: Case and control audio samples were obtained from institutional and publicly available sources. A machine-learning model was built using Python software. RESULTS: The initial 110 audio samples used to test and train the model were retested after format conversion and file deidentification. Each sample was tested 5 times yielding a precision of 100%. Sensitivity was 92.73% (95% CI: 82.41%-97.98%) and specificity was 98.18% (95% CI: 90.28%-99.95%). One hundred thirteen prospective samples, which had not yet interacted with the model, were then tested. Precision was again 100% with a sensitivity of 88.89% (95% CI: 78.44%-95.41%) and a specificity of 66% (95% CI: 51.23%-78.79%). DISCUSSION: VPD affects nearly 100% of patients with unrepaired overt soft palatal clefts and up to 30% of patients who have undergone palatoplasty. VPD can render patients unintelligible, thereby accruing significant psychosocial morbidity. The true burden of VPD in LMICs is unknown, and likely exceeds estimates from HICs. The ability to access a phone-based screening machine-learning model could expand access to diagnostic, and potentially therapeutic modalities for an innumerable amount of patients worldwide who suffer from VPD.

Easing the Burden on Caregivers- Applications of Artificial Intelligence for Physicians and Caregivers of Children with Cleft Lip and Palate.

OBJECTIVE: Many caregivers of children with cleft lip and palate experience a high level of anxiety throughout their child's medical and surgical care. We aim to evaluate artificial intelligence (AI) as a tool to mitigate these feelings and can aid clinicians in the development of robust pediatric educational materials for caregivers and families. DESIGN: Thirteen of the most common postoperative questions following cleft lip and/or palate repair were developed by an expert panel of senior Pediatric Plastic Surgeons and were posed to ChatGPT. Professional answers from the expert panel were provided and compared to responses from ChatGPT. A literature review was also conducted to generate a new support model for caregivers with children undergoing a surgical procedure. SETTING: Department of Pediatric Plastic Surgery at a metropolitan Children's Hospital. PARTICIPANTS: Senior Pediatric Plastic Surgeons at a metropolitan Children's Hospital. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The primary outcome was to determine the ability of ChatGPT to respond to common postoperative questions and to develop a model for AI assistance in family-centered perioperative care. RESULTS: ChatGPT had a postoperative question response accuracy rate of 69% when compared with subject matter expert responses, with its greatest errors being information errors. An extensive literature search revealed that AI can assist in multiple traditional perioperative strategies to reduce caregivers and patient anxiety. CONCLUSIONS: Artificial Intelligence can help to reduce the burden of generating patient education materials as well as support caregivers in multiple aspects and perioperative care.

Frontal sinus hypoplasia in unoperated older patients with craniosynostosis: a pilot study.

PURPOSE: The purpose of this study is to determine whether patients with unoperated craniosynostosis have different frontal sinus pneumatization than unaffected controls. METHODS: Retrospective review was performed between 2009 and 2020 of previously unoperated patients with craniosynostosis older than 5 years old at first presentation to our institution. Total frontal sinus volume (FSV) was calculated using 3D volume rendering tool in Sectra IDS7 PACS system. Age-matched normative FSV data was collected from 100 normal CT scans for the control group. The two groups were statistically compared using Fisher's exact test and T-test. RESULTS: Study group included nine patients, 5-39 years old, median age 7 years. Frontal sinus pneumatization was absent in 12% of the normal 7-year-old controls, while frontal sinus pneumatization was absent in 89% of the studied craniosynostosis patients (p < .001). Mean FSV of the study group (113 ± 340 mm3) was significantly different from that of age matched control mean FSV (2016 ± 2529 mm3) (p = .027). CONCLUSIONS: Frontal sinus pneumatization is suppressed in unreleased craniosynostosis and may be an intracranial space conservation phenomenon. This absent frontal sinus can have implications in future frontal region trauma and frontal osteotomies.

Improved Confidence and Clinical Application: The Effects of a Longitudinal Suture Curriculum for Medical Students.

OBJECTIVE: The ability to competently suture is an expected skill for graduating medical students, but many graduates report feeling unprepared to perform this skill. This study aimed to improve student confidence and clinical readiness for third-year clerkships by implementing a novel, mandatory 7.5-hour longitudinal suturing skills curriculum across the first 3 years of medical school. METHODS: The required suturing skills curriculum was implemented for all medical students throughout the first 3 years of medical school at a large academic health center in the mid-South United States. Precurriculum (n = 167) and postcourse (n = 148) surveys were administered to first-year students in the first year of the curriculum (2017-2018), and a parallel follow-up survey was administered to this cohort in 2020 after students completed their clinical clerkship year (n = 82). Aggregate changes in students' survey responses were analyzed for proper instrument position, simple interrupted sutures, and instrument ties using independent groups Mann-Whitney U tests and Rosenthal correlation coefficients for effect sizes. RESULTS: Statistically significant improvement from pre to post was observed in student comfort in performing three basic skills: proper instrument position (P < 0.001), simple interrupted suture (P < 0.001), and instrument ties (P < 0.001). These pre-post gains were sustained at 2-year follow-up (P < 0.001). Also, the majority of students (66%) reported they were very or completely prepared to suture wounds during their clerkships. Most (83%) also reported they had successfully sutured patient wounds during third-year clerkships without needing significant direction or guidance. CONCLUSIONS: We found that a longitudinal suture curriculum with dedicated faculty involvement can improve student confidence in suturing and overall preparedness for third-year clerkships. Although the study is limited to ratings of student comfort and self-reported performance as well as some attrition of responses at postcourse survey and postclerkship survey, the findings highlight the importance of a focused curriculum dedicated to teaching basic suturing skills. Our findings also contribute to the limited body of work examining longitudinal surgical skills development for medical students.

National Trends in Orthognathic Surgery: A Multi-Institutional Analysis of 6640 Patients.

BACKGROUND: LeFort I osteotomy (LF1) and bilateral sagittal split osteotomy (BSSO) have unique operative challenges and inherent anatomic considerations that predispose to certain adverse outcomes, yet their respective complication profiles continue to be debated given conflicting results from single-center investigations. The purpose of this study is to perform a multi-institutional analysis of complications, socioeconomic trends, and financial charges associated with orthognathic surgery. METHODS: A retrospective cohort study was conducted of orthognathic procedures performed in the United States from 2010 through 2020 using the Pediatric Health Information System. Patients younger than 12 years of age were excluded. Medical complications, surgical complications, and admission costs were compared across procedures. Socioeconomic determinants and trends across regions of the country were also analyzed. RESULTS: During the study interval, 6640 patients underwent orthognathic surgery, including LF1 (59.2%, n=3928), BSSO (14.4%, n=959), and double-jaw surgery (26.4%, n = 1753). Patients undergoing LF1 were more likely to experience overall complications ( P <0.001), infections ( P <0.001), and blood transfusions ( P <0.001) than those undergoing BSSO. High-volume hospitals were more likely to perform double-jaw procedures than other hospitals ( P <0.001), yet high-volume hospitals were less likely to have surgical complications ( P =0.014). Patient admission charges related to orthognathic operations at high-volume hospitals were less than other hospitals ( P <0.001). Household income was higher for orthognathic procedures performed at high-volume hospitals ( P <0.001). White patients were 1.5 times more likely to choose a farther, higher volume hospital for orthognathic surgery than the one locally available ( P =0.041). CONCLUSIONS: LeFort I osteotomy procedures had higher infection and transfusion rates than BSSO procedures. High-volume hospitals were more likely to perform double-jaw procedures, yet high-volume hospitals had fewer complications and decreased admission charges. Future study will be needed to further elucidate case-mix index details and socioeconomic determinants of health contributing to these disparities.

An Enhanced Audiologic Protocol for Early Identification of Conductive Hearing Loss in Patients with Cleft Palate.

OBJECTIVE: To characterize the onset and prevalence of conductive hearing loss (CHL) in pediatric patients with cleft palate (CP) prior to palatoplasty with an enhanced audiologic protocol. DESIGN: Retrospective cohort study. SETTING: Multidisciplinary cleft and craniofacial clinic at a tertiary care center. PATIENTS: Patients with CP who received audiologic workup pre-operatively. Patients with bilateral permanent hearing loss, expiration prior to palatoplasty, or no pre-operative data were excluded. INTERVENTIONS: Patients with CP born February 2019 to November 2019 who passed newborn hearing screening (NBHS) received audiologic testing at 9 months of age (standard protocol). Patients born December 2019 to September 2020 underwent testing prior to 9 months of age (enhanced protocol). MAIN OUTCOME MEASURES: Age of identification of CHL in patients after implementation of the enhanced audiologic protocol. RESULTS: The number of patients who passed their NBHS in the standard protocol (n = 14, 54%) and the enhanced protocol (n = 25, 66%) did not differ. Infants who passed their NBHS, but demonstrated hearing loss on subsequent audiologic testing did not differ between enhanced (n = 25, 66%) and standard cohort (n = 14, 54%). Of patients who passed NBHS in the enhanced protocol, 48% (n = 12) had CHL identified by 3 months, and 20% (n = 5) by 6 months of age. With the enhanced protocol, patients who did not undergo additional testing post NBHS significantly dropped from 44.9% (n = 22) to 4.2% (n = 2) (P < .0001). CONCLUSION: Even with passed NBHS, CHL is still present for infants with CP pre-operatively. Earlier and more frequent testing for this population is recommended.

Management of an open nasofrontal encephalocele during the first day of life.

Nasofrontal encephaloceles are extremely rare craniofacial defects that present with herniation of cerebral tissue through the junction of the frontal and nasal bones. They often have a cutaneous covering which allows management to be delayed until early infancy, decreasing the risks of anesthesia and acute blood loss. Further bone development also facilitates cranial remodeling. Encephaloceles with a compromised cutaneous envelope pose an imminent threat to life due to the risk of meningitis, necessitating surgical repair in the first days of life. This report presents a patient born with an open nasofrontal encephalocele that underwent encephalocele excision, dural repair, and cranial remodeling on the first day of life. Anterior encephaloceles represent a spectrum of uncommon craniofacial dysraphias. Given the rarity of these diseases, it is important to understand their many presentations and the treatment options that exist for each. When the cutaneous covering of the encephalocele is compromised, surgical correction must be undertaken urgently to mitigate the mortality associated with neonatal meningitis. This represents the first report of an open nasofrontal encephalocele managed in the first day of life. A multidisciplinary surgical approach involving the neurosurgical and craniofacial surgical teams is paramount to the treatment and survival of such complicated patients.

Managing Bilateral Oro-Sino-Orbital Fistulae in the Setting of Bilateral Tessier IV Clefts.

ABSTRACT: The number IV orofacial cleft is extremely rare, and reports on long-term outcomes are limited. Here we present the management of a child born with bilateral Tessier number IV clefts and microphthalmia, who developed bilateral oro-sino-orbital fistulae. He presented 8 years after his index procedure with persistent ocular drainage and radiographic evidence of bilateral oro-sino-orbital fistulae. His globes maintained light perception, and in order to protect them from chemical reflux he underwent fistula obliteration with demineralized bone matrix and acellular dermal matrix. His orbits were reconstructed by Imre and conjunctival flaps. In the presence of marginally functioning globes, the importance of timely intervention is critical in order to preserve residual ocular function. Light perception vision assists in the maintenance of circadian rhythm and physiologic functions that are critical to the developing pediatric patient. This case also emphasizes the importance of a multi-disciplinary team in the correction of complex craniofacial deformities.

Resorbable Versus Titanium Hardware for Rigid Fixation of Pediatric Upper and Midfacial Fractures: Which Carries a Lower Risk Profile?

PURPOSE: Titanium associated risks have led to interest in resorbable hardware for open reduction and internal fixation (ORIF) of pediatric facial fractures. This study aims to systematically review and compare the outcomes of titanium/resorbable hardware used for ORIF of upper/midfacial fractures to determine which hardware carries a higher complication rate in the pediatric patient. METHODS: Studies published between 1990 and 2020 on the ORIF of pediatric upper/midfacial fractures were systematically reviewed. A retrospective institutional review was also conducted, and both arms were compiled for final analysis. The primary predictor value was the type of hardware used and the primary outcome was the presence of a complication. Fisher's exact test and 2-proportion 2-tailed z-test calculations were used to determine statistical significance, which was defined as a P value < .05. The low quality of published evidence precluded meta-analysis. RESULTS: Systematic review of 23 studies identified 659 patients, and 77 patients were identified in the institutional review. A total of 736 patients (299 resorbable, 437 titanium) were included in the final analysis. Total complication rate was 22.8%. The titanium group had a higher complication rate (27 vs 16.7%; P < .01), and more often underwent elective hardware removal (87.3 vs 0%, P < .01). In each hardware subgroup, the incidence of complications was analyzed by fracture site. In the titanium group, complication incidence was higher when treating maxillary fractures (32.8 vs 22.9%, P = .03). When comparing the 2 hardware groups by fracture site, maxillary fractures had a higher rate of complications when treated by titanium hardware compared with resorbable hardware (32.8 vs 18%, P < .01). CONCLUSIONS: Upper/midfacial pediatric fractures requiring ORIF, especially maxillary fractures, may be best treated with resorbable hardware. Additional hardware-specific outcomes data is encouraged.

Sport participation and related head injuries following craniosynostosis correction: a survey study.

OBJECTIVE: Craniosynostosis (CS) affects about 1 in 2500 infants and is predominantly treated by surgical intervention in infancy. Later in childhood, many of these children wish to participate in sports. However, the safety of participation is largely anecdotal and based on surgeon experience. The objective of this survey study was to describe sport participation and sport-related head injury in CS patients. METHODS: A 16-question survey related to child/parent demographics, CS surgery history, sport history, and sport-induced head injury history was made available to patients/parents in the United States through a series of synostosis organization listservs, as well as synostosis-focused Facebook groups, between October 2019 and June 2020. Sports were categorized based on the American Academy of Pediatrics groupings. Pearson's chi-square test, Fisher's exact test, and the independent-samples t-test were used in the analysis. RESULTS: Overall, 187 CS patients were described as 63% male, 89% White, and 88% non-Hispanic, and 89% underwent surgery at 1 year or younger. The majority (74%) had participated in sports starting at an average age of 5 years (SD 2.2). Of those participating in sports, contact/collision sport participation was most common (77%), and 71% participated in multiple sports. Those that played sports were less frequently Hispanic (2.2% vs 22.9%, p < 0.001) and more frequently had undergone a second surgery (44% vs 25%, p = 0.021). Only 9 of 139 (6.5%) sport-participating CS patients suffered head injuries; 6 (67%) were concussions and the remaining 3 were nondescript but did not mention any surgical needs. CONCLUSIONS: In this nationwide survey of postsurgical CS patients and parents, sport participation was exceedingly common, with contact sports being the most common sport category. Few head injuries (mostly concussions) were reported as related to sport participation. Although this is a selective sample of CS patients, the initial data suggest that sport participation, even in contact sports, and typically beginning a few years after CS correction, is safe and commonplace.

Pediatric Orbital Entrapment: Radiographic Findings and Their Predictive Values.

INTRODUCTION: Although orbital fractures are less common in children than adults, the literature suggests that orbital entrapment occurs more frequently in the pediatric population. Orbital entrapment is an emergency, and early diagnosis and prompt management are critical. Specific radiographic manifestations such as herniation of extraocular muscles (EOMs) through orbital fractures have led to increased suspicion and overdiagnosis of orbital entrapment. This study evaluated the value of specific radiographic findings in predicting clinical findings after pediatric orbital floor fractures. METHODS: A retrospective review at a pediatric level 1 trauma center was performed. ICD-9 and ICD-10, codes identified patients with orbital fractures. Computed tomography (CT) reports were queried for the following terms: "herniation," "herniated," "entrapped," and "entrapment." Patients 16 years and older were excluded, as were all patients who were unable to undergo EOM evaluation on presentation. Electronic medical records were reviewed for fracture type, mechanism of injury, clinical and radiographic findings, surgical interventions, and demographic information. Medical diagnosis tests, including positive and negative predictive values, sensitivity, as well as specificity, were calculated to identify the relationship between radiographic findings and specific symptomology. RESULTS: One hundred fifty-three patients with 265 orbital fractures were included. "Entrapment" was mentioned in 34.6% of CT reports, whereas the incidence of clinical entrapment was 12.4% (19/153). Radiographic fat herniation, EOM herniation, and EOM irregularity had positive predictive values of 25%, 31%, and 10%, respectively, for clinical entrapment diagnosis at the initial examination. Overall, 32.7% (50/153) of patients with orbital fractures required surgery. CONCLUSIONS: Although the radiographic description of soft tissue herniation has become interchangeable with entrapment, these CT findings alone are poorly predictive. Orbital entrapment should be diagnosed preoperatively by physical examination, with radiographs as an adjunct only. Radiographic statements without clinical correlation may lead to the improper management of pediatric facial trauma patients.

Influence of Radiographic Soft Tissue Findings on Clinical Entrapment in Patients With Orbital Fractures.

INTRODUCTION: Radiographic assessment of facial fractures with computed tomography (CT) scanning has become standard of care. As imaging resolution has improved, findings such as herniation of extraocular muscles (EOM) have become a means of diagnosing conditions like orbital entrapment. However, the sensitivity and specificity of these findings has not been well-studied. We sought to evaluate the value of radiographic findings such as fat herniation, EOM contour irregularity, and EOM herniation in predicting orbital entrapment after orbital fracture. Secondary endpoints include diplopia, abnormal EOM motility, and the need for surgical fixation. METHODS: A single institution, retrospective review at a regional level 1 trauma center was conducted. Patients with orbital fractures were identified by International Classification of Disease (ICD) codes and CT reports were queried for the terms "herniation," "herniated," "entrapped," and "entrapment." Four hundred records were analyzed. RESULTS: Sixty-seven percent of radiology reports mentioned "entrapped" or "entrapment," while the incidence of clinical entrapment was 2.8%. The odds of entrapment, diplopia, and abnormal EOM motility were higher in those with EOM herniation; however, EOM herniation had a positive predictive value of 7.9% for clinical entrapment. Fat herniation alone and EOM contour irregularity had positive predictive values of 4.2% and 4.8%, respectively. CONCLUSIONS: While the odds of entrapment appear higher in patients with EOM herniation, this imaging finding is not predictive of clinical entrapment. Fat herniation and EOM contour irregularity did not have higher odds of entrapment, nor were they predictive. Diagnosis of orbital entrapment should be based primarily on physical exam, with CT as an adjunct only. The assumption that radiographic findings indicate orbital emergencies may result in unnecessary interfacility transfers, subspecialist consultations, and emergency operative procedures.

Surgical Approach in a Patient With Agnathia-Otocephaly Complex: Three-Stage Mandibular Distraction Protocol.

Agnathia-otocephaly complex (AOC) is a rare malformation complex of the first pharyngeal arch that is characterized by agnathia/dysgnathia, microstomia, aglossia/hypoglossia and variable displacement of the ears. Only 11 post-infancy patients with severe AOC have been described in the literature, and the incidence of this malformation complex is estimated to be 1 per 70,000 births. In this brief clinical study, the authors describe the case of an 18-year-old female diagnosed with AOC who underwent a 3-step mandibular distraction protocol with an external distraction device. The surgical protocol the authors used was unique in that we first placed a tissue expander in the submental area to enlarge the skin envelope in an effort to mitigate skeletal relapse from soft tissue forces. Furthermore, the way in which the authors slowed the activation of the distraction device to allow for soft tissue healing behind the pins was a novel component of the patient's treatment. The 3-step mandibular distraction protocol the authors present in this study increased the length of the mandible by 20 mm, and nearly doubled the size of the patient's mandible from an initial volume of 3.62 cm to a post-operative volume of 6.89 cm. Future surgeries will aim to improve the function of our patient's expanded mandible. Most important of all, the surgical treatment authors are presenting led to a significant improvement in our patient's physical appearance and 3d quality of life.

NAM Therapy-Evidence-Based Results.

Many orthodontists working on patients with cleft lip and palate (CLP) have shown great enthusiasm for presurgical infant orthopedics (PSIO) to improve surgical outcomes with minimal intervention. Even though every clinician aims to use the best treatment modality for their patients, PSIO effects can be confounded by surgical type and timing of the primary repair, as is discussed in many studies. In such cases, one should be cautious when evaluating the particular outcomes for patients with CLP since it is difficult to differentiate the sole effect of an individual surgical or orthodontic intervention. As with any treatment methodology, nasoalveolar molding (NAM) has both benefits and limitations. Commonly cited concerns with NAM, and PSIO in general, include increased cost, increased burden of care, and a negative impact on maxillary growth. However, NAM cannot be deemed as having apparent long-term negative or positive effects on skeletal or soft tissue facial growth, based on previous studies. A review of the literature suggests that NAM does not alter skeletal facial growth when compared with the samples that did not receive PSIO. Nevertheless, the published studies on NAM show evidence of benefits to the patient, caregivers, the surgeon, and society. These benefits include documented reduction in severity of the cleft deformity prior to surgery and as a consequence improved surgical outcomes, reduced burden of care on the care givers, reduction in the need for revision surgery, and consequent reduced overall cost of care to the patient and society.

Surgical management of craniosynostosis in the setting of a ventricular shunt: a case series and treatment algorithm.

PURPOSE: Cerebrospinal fluid diversion via ventricular shunt is a common treatment for hydrocephalus. Change in cranial morphology associated with a sutural fusion has been termed shunt-related or induced craniosynostosis (SRC) or craniocerebral disproportion (CCD). We present a series of patients with SRC who underwent cranial vault remodeling (CVR) and our treatment algorithm. METHODS: Thirteen patients were retrospectively reviewed who had SRC and CVR; 92% of patients had a ventriculoperitoneal (VP) shunt placed for largely intraventricular hemorrhage of prematurity (69% of patients) at a mean age of 2.2 months. The shunt revision rate was 38.4%, and 54% of patients had a programmable shunt placed initially. RESULTS: The mean age at time of CVR was 3.6 years old. The most commonly affected sutures (CT confirmed) were the sagittal and coronal sutures, with three patients exhibiting pancraniosynostosis. The mean time from placement of the shunt to CT evidence of sutural fusion was 2.0 years. Abnormal head shape was noted in all 13 patients; 11 of these also had either chronic headaches, papilledema, seizures, or behavioral changes in the setting of functional shunt. Mean follow-up after the initial CVR was 3.3 years. No shunt infections were attributed to the CVR. The families of all patients were contacted and reported improvement in head shape with 60% of families reporting improvement in behavior, 75% reported improvement in headaches, and 40% reported decrease in seizure frequency or intensity. Shunt setting or type was not routinely changed after CVR. CONCLUSIONS: Our threshold for CVR in SRC is met when shunt malfunction has been ruled out and there are (1) radiographic evidence of craniosynostosis, (2) signs of increased ICP clinically or radiographically, and (3) cranial dysmorphism, i.e., dolichocephaly. The majority of cases of SRC result in improved cranial morphology in addition to some abatement of the symptoms of increased intracranial pressure. Early involvement of an experienced craniofacial/neurosurgical team could allow for early diagnosis and intervention which may prevent progression to more severe deformities. SRC is a complex entity, with multiple etiologies, and a future study is needed.
