| Abstract: | Introduction: External ear malformations represent a spectrum of congenital anomalies that may involve the external auditory canal (EAC), tympanic membrane (TM), or associated structures. A rare anomaly, the EAC skin wedge, results from incomplete canalization during embryologic development. This report presents the clinical presentation, diagnostic evaluation, and surgical management of this condition. Objective: To detail the successful surgical management of an isolated EAC skin wedge and demonstrate the applicability of argon laser in treating these congenital anomalies. Methods: A 13-month-old female presented with recurrent otitis media and mild bilateral conductive hearing loss. Physical examination revealed a fan-like skin wedge spanning the EAC to the TM. Imaging with temporal bone computed tomography confirmed the extent of the anomaly. Under general anesthesia, the skin wedge was ablated using an argon laser, followed by antibiotic-soaked packing to prevent scarring and recurrence. Follow-up audiometry and endoscopic evaluations assessed outcomes. Results: The procedure was well-tolerated, with no intraoperative complications. At 3 weeks and 3 months postoperatively, no recurrence of the skin wedge was observed, and audiometry normalized. The patient demonstrated improved middle ear ventilation and resolution of conductive hearing loss. Conclusions: This case demonstrates the successful use of argon laser in the management of a rare congenital EAC anomaly. Argon lasers offer precise ablation and excellent hemostasis, making them a valuable option for similar cases. This report emphasizes the importance of tailored surgical approaches for rare pediatric ear malformations. [ABSTRACT FROM AUTHOR] |
