Abstract

Objective: We describe the successful surgical management of a pediatric patient with multiple preauricular appendages and highlight the importance of early investigation of associated congenital malformations, particularly renal anomalies. Methods: An eight-year-old boy presented with four congenital preauricular appendages. Imaging of the kidneys and urinary tract, and high-frequency ultrasonography of the preauricular lesions were performed. Surgical excision was subsequently performed under sedation. Results: The lesions were completely removed, and deep cartilaginous components were identified in two of them. The patient experienced an uneventful postoperative course, with an excellent aesthetic outcome, no hearing loss, and no complications. Conclusion: Preauricular appendages, even when isolated, may be associated with renal and auditory abnormalities. Comprehensive evaluation and complete surgical excision of the lesions are key to preventing complications including cyst formation and recurrence. While none were identified in this patient, evaluation for associated syndromes is also recommended
