Abstract

Objective: Branchial arch remnants are a well-encountered pathology in pediatric patients. In the majority of cases, these vestiges are superficial and benign, save for minor cosmetic deformity or discomfort. Although branchial arch remnants in the form of skin vestiges are commonly removed, there remains a lack of in-depth study regarding appropriate protocol and experience under local anesthesia. Design: A retrospective review of subjects undergoing first branchial arch vestige excision utilizing local anesthesia was conducted (2017-2021). Demographics were recorded, including age, sex, comorbidities, vestige location, presence of tracts, post-operative complications, and significant associations. Results: A total of 178 subjects were identified for inclusion. The mean patient age during the procedure was 18.4 ± 38.3 months. A total of 34 patients presented with a current or prior comorbidity (24.7%). The most common location of the branchial remnant was the preauricular region (79.2%). Most patients were without complication (96.1%). Secondarily developed branchial anomalies were significantly associated with complications as compared to congenital anomalies (22.2% vs 3.0%, P < .042). Additionally, patients with a past medical history were significantly more likely to develop a post-operative complication (71.4% vs 22.6%, P < .13). Conclusion: In-office branchial remnant removal is a safe procedure in the young pediatric patient. Complication rates are low; patients with a significant past medical history may be more likely to incur postoperative complications. Additionally, patients with secondary vestige development may also be more likely to develop complications. Further in-office procedures are encouraged.
