Surgical Management of Sirenomelia: A Case Study.

Background: Sirenomelia is a rare congenital condition characterized by fusion of the lower limbs. Patients with sirenomelia generally do not survive long after birth because the condition is associated with multisystem organ dysfunction due to developmental anomalies. Considering the low incidence and few cases surviving the neonatal period, there is minimal understanding regarding the surgical management of sirenomelia. We present a unique case of an infant born with type 1 sirenomelia, absence of external genitalia, presence of a cloaca, absence of the bladder, and presence of an imperforate and vestigial anus, who not only survived the birth process, but, at the age of 11 months, was determined to be a candidate for surgical separation of the lower extremities. Methods: This case was approached much like a dorsal rectangular flap syndactyly release. Large Z-plasty flaps were designed and raised, and the soft tissue within the skin bridge was meticulously dissected to preserve anatomy and to provide adequate skin flaps without perineal skin grafting. A quadrangular flap was designed to reconstruct the perineum and produce a neo-vulva using de-epithelialization. Results: Successful lower extremity separation was achieved. There were no major postoperative complications. The patient progressed with lower extremity function, and eventually achieved independent ambulation. Conclusions: Management of sirenomelia is incredibly challenging, and data to guide surgical management are limited. This report details our approach to a successful lower extremity separation, repair, and neo-vulvar reconstruction in a case of type I sirenomelia.

Revisiting Bipedicled Flaps for Lower Extremity Distal Third Defects.

BACKGROUND: Lower extremity reconstruction of the distal third of the leg is challenging. Free tissue transfer is the criterion standard. The COVID-19 pandemic encouraged seeking alternatives for resource consuming procedures. Bipedicled flaps are flaps with a dual-source subdermal perfusion. The purpose of this study was to assess outcomes of patients who had bipedicled flaps primary or auxiliary local flap for distal third leg/foot reconstruction. METHODS: A retrospective review of patients undergoing lower extremity reconstruction (2020-2021) was performed. Inclusion criteria were patients older than 18 years with lower extremity wounds secondary to traumatic injury for which bipedicled flaps were used in the reconstruction. Exclusion criteria included lower extremity wounds secondary to peripheral vascular disease or diabetes. RESULTS: Fourteen patients were included in the study. All patients had distal third of the leg/foot wounds, and 12 patients (87.5%) had concurrent leg fractures. In 8 patients (57.1%), the bipedicled flap was used to decrease the wound size and facilitate another concurrent flap: hemisoleus (21.4%), anterior tibialis muscle turnover (14.3%), medial plantar artery (14.3%), and posterior tibial artery perforator (14.3%). Mean wound size for bipedicle flaps used alone was 42.0 ± 18.3 cm2, whereas wounds that required a bipedicled flap with an additional flap were 69.9 ± 80.8 cm2 (P = 0.187). Two patients had partial flap necrosis (14.3%) but healed their defect. One patient had nonunion (7.1%). Limb salvage rate was 100%. CONCLUSIONS: Bipedicled flaps can be used as an alternative to free flaps in distal third leg/foot defects in select patients. If distal extremity wounds cannot be covered with a bipedicled flap alone, the flap can be used an accessory flap to facilitate reconstruction with other local flaps.

Contralateral C7 nerve transfer for severe pediatric brachial plexus injuries: donor site morbidity.

BACKGROUND: Pediatric brachial plexus injuries (BPI) can have a devastating impact on upper extremity function. With localized lesions, nerve grafting and transfers are well-described. However, reconstruction of pan-plexus (C5-T1) injuries (PPI) requires donor nerves outside of the brachial plexus. The cross C7 (CC7) nerve transfer extended with sural nerve grafts to the contralateral recipient nerve offers the advantage of supplying robust donor axons. Though controversial in the West, CC7 transfer is routine in many Asian centers. We present a case series of pediatric patients who underwent CC7 transfer for BPI. Our objective was to catalog donor site morbidity incurred by transferring the C7 nerve root. METHODS: This retrospective study was approved by the Institutional Review Board of our university. INCLUSION CRITERIA: patients under 18 years old that underwent CC7 nerve transfer for BPI at our health system between 2021 and 2022. A chart review was completed to collect demographic and outcomes data. RESULTS: Three patients underwent a complete CC7 transfer between 2021 and 2022 for BPI reconstruction. All patients underwent concomitant additional nerve transfers. Post-operative donor site sensory deficits were minimal and transient in all but one patient, who reported mild but persistent paresthesia of the donor side hand with movement of recipient side digits; however, no patients suffered donor site motor deficits (Table 1). CONCLUSIONS: We conclude that CC7 nerve transfer is a safe surgical option to provide additional donor motor axons for PPI in pediatric patients.

Minimally-Invasive Corneal Neurotization (MICN): 10 Year Update in Technique and Lessons Learned Including Novel Donor Transfer of the Great Auricular Nerve.

VIDEO PLUS SUBMISSION SUMMARY: Corneal anesthesia, caused by lack of corneal innervation, is a rare but devastating condition that can lead to neurotrophic keratopathy 1, corneal ulceration, scarring, and blindness. Minimally-Invasive Corneal Neurotization (MICN) enables transfer of regional donor sensory nerves to the cornea to provide sensation and ocular protection. Here, we provide an update on technical advances and modifications that have arisen over ten years that have refined the surgery. We provide intraoperative step by step videos of corneal neurotization, noting its critical steps, pitfalls, and caveats. This video submission will focus on the novel technique of utilizing the greater auricular nerve with a sural nerve graft extension as the donor nerve for the procedure. The steps and considerations depicted will allow surgeons to carry out corneal neurotization efficiently, safely, and effectively.

A case report of gender-affirming mastectomy in a transgender individual with breast cancer.

Background: Gender-affirming mastectomy (GAM), in contrast to simple mastectomy (SM), utilizes preservation of subcutaneous and breast tissue to produce a cosmetically favorable result for transgender patients, however does not remove all future malignancy risk. Here we present a case report of a transmale patient who was evaluated for GAM and subsequently found to have a malignant breast mass, necessitating multi-disciplinary intervention and coordination between breast and plastic surgery teams. This patient's unique and rare presentation with breast cancer prior to GAM emphasized the paucity of previously detailed cases in the literature and demonstrated the likely degree of variability in decision-making for treatment of these patients without universal guidelines for management. Case Description: The patient is a 47-year-old African American transgender male who was found to have a 3-cm breast mass on routine pre-operative mammographic screening prior to GAM. Pathology confirmed grade II invasive ductal carcinoma (IDC) and further genetic testing showed the patient was BRCA2 positive. The breast and plastic surgery teams coordinated the GAM to best address the mass while achieving cosmetic goals. This case was complicated by positive nipple margins on intra-operative cold specimen, which necessitated deviation from the initial plan to perform bilateral nipple grafts, and instead utilized excess areolar tissue from the left nipple to reconstruct the contralateral right nipple. Graft survival and overall repair quality at 6 weeks was satisfactory to both patient and provider. Conclusions: This case highlights several of the challenges encountered when considering or performing GAMs in transmale patients with underlying breast cancer. Surgical considerations for these patients differ from cisgender individuals undergoing mastectomy for oncologic breast findings. Further research is needed to better determine the ideal operative practice and ideal follow-up screening for these patients.

Virtual Interviews for the Independent Plastic Surgery Match: A Modern Convenience or a Modern Misrepresentation?

OBJECTIVE: The virtual interview for residency and fellowship applicants has previously been utilized preliminarily in their respective processes. The COVID-19 pandemic forced many programs to switch to a virtual interview process on short notice. In the independent plastic surgery process, which was underway when the pandemic started, applicants had a heterogeneous experience of in-person and virtual interviews. The purpose of this study was to assess if applicants prefer a virtual interview experience to an in-person interview as well as determine if virtual interview applicants had a different opinion of a program compared to the in-person interview applicants. DESIGN/SETTING/PARTICIPANTS: The 2019 to 2020 applicants who interviewed at the Indiana University Independent Plastic Surgery program were administered an anonymous online survey about their interview experience at our program. RESULTS: Our survey response was 60% (18/30). The in-person interview group (n = 10) rated their overall interview experience higher than the virtual interview group (n = 8) 8.8 vs 7.5 (p = 0.0314). The in-person interview group felt they became more acquainted with the program, the faculty, and the residents more than the virtual group (4.7 vs 3.25, p < 0.0001) (4.3 vs 3.25, p = 0.0194) (4.3 vs 2.75, p < 0.0001). The majority of applicants favored in-person interviews (16/18, 88.9%). The in-person interview group spent significantly more money on their interview at our program compared to the virtual interview group ($587 vs $0, p < 0.0001). CONCLUSION: Our study demonstrated that the virtual interview process was an efficient process for applicants from both a financial and time perspective. However, the virtual interview process left applicants less satisfied with their interview experience. The applicants felt they did not become as acquainted with the program as their in-person counterparts. The virtual interview process may play a large role in residency and fellowship applications in the future, and programs should spend time on how to improve the process.

Power-Optimizing Repair for Distal Biceps Tendon Rupture: Stronger and Safer.

Purpose: Many approaches have been described to accomplish tendon reattachment to the radial tuberosity in a distal biceps tendon rupture, with significant success, but each is associated with potential postoperative complications, including posterior interosseous nerve (PIN) injury. To date, there has been no consensus on the best approach to the repair. The purpose of this study was to evaluate the supination strength and the distance of drill exit points from the PIN in a power-optimizing distal biceps repair method and compare the findings with those of a traditional anterior approach endobutton repair method. Methods: Cadaveric arms were dissected to allow for distal biceps tendon excision from its anatomic footprint. Each arm was repaired twice, first with the power-optimizing repair using an anterior single-incision approach with an ulnar drilling angle and biceps tendon radial tuberosity wraparound anatomic footprint attachment, then with the traditional anterior endobutton repair. Following each repair, the arm was mounted on a custom-built testing apparatus, and the supination torque was measured from 3 orientations. The PIN was then located posteriorly, and its distance from each repair exit hole was measured. Results: Five cadaveric arms, each with both the repairs, were included in the study. On average, the power-optimizing repair generated an 82%, 22%, and 13% greater supination torque than the traditional anterior endobutton repair in 45° supination, neutral, and 45° pronation orientations, respectively. On average, the power-optimizing repair produced drill hole exit points farther from the PIN (23 mm) than the traditional anterior endobutton repair (14 mm). Conclusions: The power-optimizing repair provides a significantly greater supination torque and produces a drill hole exit point significantly farther from the PIN than the traditional anterior endobutton approach. Type of study/level of evidence: Therapeutic III.

Penetrating trauma associated with findings of multiple evanescent white dot syndrome in the second eye: coincidence or an atypical case of sympathetic ophthalmia?

PURPOSE: To report a case of sympathetic ophthalmia (SO) resembling multiple evanescent white dot syndrome (MEWDS). METHODS: Retrospective chart review. RESULTS: A 17-year-old girl with a ruptured globe in the right eye underwent prompt primary repair and vitrectomy, scleral buckling, and silicone oil infusion 3 weeks later. Eight weeks after injury, she presented with visual loss in the left eye. Fundus examination in the left eye disclosed optic disk swelling and well-circumscribed, 100 to 500 microm diameter gray-white lesions at the level of the retinal pigment epithelium (RPE) posterior to the equator, sparing the fovea. On fluorescein angiography, the lesions appeared as areas of blocked choroidal fluorescence in the arterial phase and were associated with dye leakage in a wreathlike pattern during venous filling. Dye leakage occurred at the optic disk. Visual field testing showed depressed central sensitivity and an enlarged blind spot in the left eye. The patient was treated with prednisone and underwent diagnostic enucleation of the right eye. Histopathology showed rare choroidal granulomata and pigment phagocytosis. Vision improved to 20/20 in the left eye, and the window defects persisted. Visual field testing 6 months later was normal. One month after discontinuing prednisone, new areas of RPE hypopigmentation developed. Two weeks later, choroidal inflammation recurred and periphlebitis developed. CONCLUSION: This case indicates that SO can mimic MEWDS.
