A multimetric health literacy analysis of online gender affirmation surgery materials: From facial to genital surgery.

BACKGROUND: The transgender patient population is expanding, and gender affirming surgery (GAS) volume is increasing. Accurate, comprehensive, and easily navigable resources on GAS are lacking. We aim to evaluate the readability of online materials for specific gender affirming surgical procedures to identify mechanisms of improving information access for transgender patients. MATERIALS AND METHODS: "Facial feminization", "facial masculinization", "MTF breast augmentation", "FTM chest masculinization", "MTF vaginoplasty", "metoidioplasty", and "FTM phalloplasty" were searched on Google. Per keyword, the first 75 text-containing results were included. Text was analyzed for reading difficulty using the Flesch-Kincaid Reading-Ease (FKRE) test and grade level using the Flesch-Kincaid Grade Level (FKGL) formula, Gunning Fog Index (GFI), Simple Measure of Gobbledygook (SMOG), and Coleman-Liau Index (CLI). Scores were compared using independent t-and ANOVA tests (α = 0.05). RESULTS: Mean readability scores (FKRE 37.44) and grade-levels (FKGL 12.87, GFI 15.61, SMOG 11.91, CLI 15.00) correlated with college-level difficulty. Masculinizing surgical materials were more difficult to read than feminizing ones (p ≤ 0.023). Top surgery materials were easier to read than facial and genital surgery materials (p ≤ 0.013). Specifically, chest masculinization resources were more difficult to read than those for breast augmentation (p ≤ 0.006). No differences were found between facial feminization and masculinization surgery resources, nor between resources for different gender affirming genital surgeries. CONCLUSION: Online GAS materials are written above the recommended 6th grade reading-level, with resources for transgender men being significantly more challenging to understand. Improving readability of online resources can help overcome barriers to care for the transgender patient population.

Use of the Vertical Profunda Artery Perforator Flap to Capture the Dominant Perforator: A Cadaver Dissection and Imaging Study.

BACKGROUND: While the originally described transverse profunda artery perforator (tPAP) flap is designed to capture the first profunda perforator, our group hypothesized the dominant perforator may not always be captured in this configuration. This study maps the location of dominant profunda perforators using imaging and cadaveric dissections to determine the probability of capturing dominant perforators with the transverse flap design versus the vertical PAP (vPAP) variant. METHODS: Fifty preoperative magnetic resonance angiogram or computed tomographic angiogram scans (100 total extremities) were examined from autologous breast reconstruction patients between 2015 and 2019. Profunda perforator characteristics that were examined included the distance from the pubic tubercle to the infragluteal fold (IGF), the distance of the perforators from the IGF, distance posterior to the gracilis, the diameter of the perforator at fascial exit, and total number of perforators present. Profunda perforator dissection was performed in 18 cadaveric extremities. Analysis included mean distance from pubic tubercle, distance posterior to the gracilis, diameter at fascial exit, and total number of perforators. RESULTS: In imaging analysis, the mean distance from the IGF to the fascial exit of all dominant perforators was 7.04 cm. The mean diameter of the dominant perforator at the fascial exit was 2.61 mm. Twenty-six thighs (26%) demonstrated dominant perforators that exited the fascia greater than 8 cm below the IGF. In cadaver dissections, the mean distance from the pubic tubercle to the fascial exit of all the dominant perforators was 10.17 cm. Nine cadaver specimens (50%) demonstrated perforators that exited the fascia greater than 8 cm below the estimated IGF. CONCLUSION: The dominant perforator can often be missed in the traditional tPAP design. The vPAP incorporates multiple perforators with a long pedicle, excellent vessel diameter, and favorable donor-site.

Subtotal Mandible Reconstruction with a Free Fibula Flap and No Skin Incisions.

Resection of large mandibular tumors followed by primary reconstruction using free tissue transfer is typically accomplished using transcutaneous cervical incisions, which provide access for ablation as well as inset of the osseous free flap. This approach offers wide exposure; however, it subjects the patient to potential facial scarring, marginal mandibular nerve injury, lip deformity/incompetence, formation of orocutaneous fistulae, as well as functional impairments to speech, mastication, and deglutition. To reduce morbidity and to preserve aesthetics, a transoral approach can be used in cases that do not require a neck dissection. This technique can be coupled with transoral dissection of the facial vessels for intraoral microanastomoses to avoid extraoral incisions altogether. We present a case of a large 17.2 cm subtotal mandibulectomy and 3-segment fibular free flap reconstruction using virtual surgical planning, with patient-specific cutting guides and reconstruction plate performed entirely transorally without any skin incisions. Although technically challenging, this is a safe and effective technique for large segmental mandibular defects, which provides superior cosmetic and functional outcomes.

Health Disparities in Incisional Hernia Presentation : An Analysis of HCUP-NIS Years 2012-2014.

INTRODUCTION: Incisional hernias (IH) are iatrogenically created in 400 000 new patients annually. Without repair, IH-associated complications can result in major illness and death. The health disparities literature suggests that under-represented patients present more frequently with surgical emergencies. The health disparities associated with IH remain relatively unstudied. METHODS: Inpatient admission data were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample for 2012-2014. Patients with IH International Classification of Diseases ninth revision were included. Analyses were completed using survey specific procedures (SAS v.9.4). Type of admission within groups was compared via Rao-Scott chi-square tests. The probability of an elective admission was modeled via SurveyLogistic Procedure. RESULTS: Of 39 296 cases, 38.5% IH admissions were urgent or emergent (nonelective). The proportion of nonelective admission was statistically higher (P < .0001) in patients >65 (40.9%) and females (40.3%). Among insurance types, self-paying patients had the highest proportion of nonelective admissions (64.3%). Racial disparities remained significant after adjusting for age, sex, and insurance. Compared with white patients, the odds of an admission being nonelective were significantly higher for black (odds ratio [OR] [95% CI]: 1.65 [1.53-1.77]], Hispanic (OR [95% CI]: 1.39 [1.28-1.51]), and other (OR [95% CI]: 1.2 [1.06-1.37]) patients. DISCUSSION: These data show that multiple at-risk patient populations are significantly more likely to require urgent admission for IH-related complications. These include older, female, non-white, and uninsured patients. Systematic efforts to ameliorate these disparities should be developed.

Experimental Model of Zygomatic and Mandibular Defects to Support the Development of Custom Three-Dimensional--Printed Bone Scaffolds.

INTRODUCTION: Autologous reconstruction of segmental craniomaxillofacial bone defects is limited by insufficient graft material, donor site morbidity, and need for microsurgery. Reconstruction is challenging due to the complex three-dimensional (3D) structure of craniofacial skeleton. Customized 3D-printed patient-specific biologic scaffolds hold promise for reconstruction of the craniofacial skeleton without donor site morbidity. The authors report a porcine craniofacial defect model suitable for further evaluation of custom 3D-printed engineered bone scaffolds. METHODS: The authors created a 6 cm critical load-bearing defect in the left mandibular angle and a 1.5 cm noncritical, nonload bearing defect in the contralateral right zygomatic arch in 4 Yucatan minipigs. Defects were plated with patient-specific titanium hardware based on preoperative CT scans. Serial CT imaging was done immediately postoperatively, and at 3 and 6 months. Animals were clinically assessed for masticatory function, ambulation, and growth. At the 6-month study endpoint, animals were euthanized, and bony regeneration was evaluated through histological staining and micro-CT scanning compared to contralateral controls. RESULTS: All 4 animals reached study endpoint. Two mandibular plates fractured, but did not preclude study completion due to loss of masticatory function. One zygoma plate loosened while the site of another underwent heterotopic ossification. Gross examination of site defects revealed heterotopic ossification, confirmed by histological and micro-CT evaluation. Biomechanical testing was unavailable due to insufficient bony repair. CONCLUSIONS: The presented porcine zygoma and mandibular defect models are incapable of repair in the absence of bone scaffolds. Based on the authors' results, this model is appropriate for further study of custom 3D-printed engineered bone scaffolds.
