Background: Feminizing fronto-orbital reconstruction involves one of four possibilities with the Ousterhout Type III anterior table frontal sinus osteotomy and setback performed in most patients while the Type I reduction recontouring is reserved for patients without frontal sinuses or thick anterior tables. However, patients with frontal sinuses and either a moderately thick anterior table or a shallow frontal sinus in the sagittal plane represent an intermediate morphology. For such morphologies, we introduce the novel Type I+ fronto-orbital reconstruction technique, consisting of frontal bone recontouring supplemented with anterior table reconstruction and split cranial bone graft.

Background: Facial feminization surgery (FFS) is the most common form of facial gender-affirming surgery. One of the current knowledge gaps is the understanding of differences among racial groups in baseline craniofacial norms for transgender and nonbinary patients.

Methods: All patients who sought consultation for FFS and underwent craniofacial computed tomography (CT) scans at a single institution between 2018 and 2023 were included.

Virtual surgical planning enables precise surgical planning and translation of this planning into the operating room. Preoperative maxillofacial computed tomography scans are compared to a reference skull to identify desired surgical changes. In facial feminization surgery, these include forehead recontouring/frontal table setback, gonial angle reduction, and possible chin repositioning/reshaping, while in facial masculinization surgery, this includes forehead augmentation and gonial angle/chin augmentation.

Background: We designed a survey to evaluate preferences of facial appearance in transgender male (TM), transgender female (TF) and gender nonbinary patients to better inform goals of facial gender affirming surgery (FGAS) in gender nonbinary patients.

Methods: TM/TF and nonbinary patients > 18 years old were identified via retrospective chart review and distributed an anonymized survey via email from October 3 to December 31, 2022. To assess facial preferences, AI-generated and open-source portraits were edited to create five image sets with a range of features from masculine to feminine for the forehead, mandible/chin and hairline.

Background: Fresh autologous cranial bone graft has traditionally been regarded as the ideal cranioplasty material; however, long-term comparisons of outcomes with modern alloplastic materials are absent in the literature. The authors evaluated complications and failures among cranioplasties performed with fresh, heterotopic, cranial bone graft versus 3 common alloplastic materials.

Methods: Random-effects meta-analyses of logit-transformed proportions were performed on studies published between 1971 and 2021 to evaluate complications and failures of cranioplasties performed with fresh, autologous, heterotopic cranial bone; polyetheretherketone (PEEK); polymethylmethacrylate (PMMA); or titanium with a mean follow-up of 12 months or more.

Background: Prescription drug misuse in transgender individuals is estimated to be three times higher than that of the general population in the United States, suggesting that opioid-reduction strategies deserve significant consideration in gender-affirming surgeries. In this work, we describe the implementation of an enhanced recovery after surgery (ERAS) protocol to reduce opioid use after facial feminization surgery.

Methods: A total of 79 patients who underwent single-stage facial feminization surgery before (n = 38) or after (n = 41) ERAS protocol implementation were included.

Background: Within the United States, access to gender-affirming operations covered by health insurance has increased dramatically over the past decade. However, the perpetually changing landscape and inconsistencies of individual state health policies governing private and public insurance coverage present a lack of clarity for reconstructive surgeons and other physicians attempting to provide gender-affirming care. This work systematically reviewed the current U.

Background: The authors studied the impact of a new, coordinated interview release date for integrated plastic surgery residencies.

Methods: A cross-sectional study of all 2020 integrated plastic surgery residencies and applicants was performed. Voluntary, anonymous surveys were administered following implementation of the interview policy.

Background: There is a paucity of data on normal intracranial volumes for healthy children during the first few years of life, when cranial growth velocity is greatest. The aim of this study was to generate a normative predictive model of intracranial volumes based on brain magnetic resonance imaging from a large sample of healthy children to serve as a reference tool for future studies on craniosynostosis.

Methods: Structural magnetic resonance imaging data for healthy children up to 3 years of age was acquired from the National Institutes of Health Pediatric MRI Data Repository.

Introduction: Orofacial clefts are the most common craniofacial anomaly observed in the United States. Permitted by recent advancements in anesthesia and multimodal pain management, there has been a trend toward outpatient cleft lip repair to alleviate hospital burden and minimize healthcare costs. The purpose of this study was to compare complication rates between outpatient and inpatient cleft lip repair from large national samples as well as identify preoperative factors that predicted discharge status.

Background: Unicoronal craniosynostosis is associated with orbital restriction and asymmetry. Surgical treatment aims to both correct the aesthetic deformity and prevent the development of ocular dysfunction. We used orbital quadrant and hemispheric volumetric analysis to assess orbital restriction and compare the effectiveness of distraction osteogenesis with anterior rotational cranial flap (DO) and bilateral fronto-orbital advancement and cranial vault remodeling (FOAR) with respect to the correction of orbital restriction in patients with unicoronal craniosynostosis.

Background: Previous research has shown that patients with metopic craniosynostosis have significantly reduced intracranial volumes (ICVs) compared to normal healthy children. Furthermore, the metopic index (ratio of midfrontozygomatic diameter to maximal cranial width) has been described as an anthropometric cranial index for patients with metopic craniosynostosis. We aimed to determine whether patients with isolated metopic ridge have significantly different ICVs or metopic indices than normal children and patients with metopic craniosynostosis.

Background: The impact of metopic craniosynostosis on intracranial volume (ICV) and ICV growth is unclear. In addition, the relationship between head circumference (HC) and ICV in these patients is not previously described.

Methods: A retrospective review of 72 patients with metopic craniosynostosis was performed.

Background: Calculation of intracranial volume from neuroimaging can be complex and time consuming. In the adult population, there is evidence suggesting that owing to its strong correlation, head circumference (HC) may be used as a surrogate for intracranial volume (ICV). We were interested in studying the correlation between HC and ICV in patients with craniosynostosis.

Introduction: Patients recovering from burn injury are at high risk of developing deep venous thrombosis (DVT). While 30-mg twice-daily enoxaparin is accepted as the standard prophylactic dose, recent evidence in injured patients suggests this dosing strategy may result in sub-optimal pharmacologic DVT prophylaxis. We hypothesized that standard enoxaparin dosing would result in inadequate DVT prophylaxis in burn patients.

Background: High-quality physician communication is the foundation for achieving high patient satisfaction. Increasing importance is placed on eliciting feedback from patients. However, there have been few studies looking at the impact of resident involvement on patient satisfaction.
