Combined Cartilage Graft Reconstruction of the Nasal Tip Complex after Resection of Nasal Tip Schwannoma: A Case Report

Abstract

ABSTRACT Objective: To present a rare case of nasal tip schwannoma and describe its resection and reconstruction using combined cartilage grafts. Methods: Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 13-year-old boy presented with a progressively enlarging nasal tip and severe left nasal obstruction causing breathing difficulties and psychosocial distress. There was a bulging septal mass obstructing 90% of the left nasal cavity. Septal incision biopsy revealed schwannoma and definitive surgery via open rhinoplasty approach was done. The non-encapsulated schwannoma extended from the subcutaneous nasal tip to the left septal mucosa. There was no evidence of skin or cartilage invasion, but prolonged pressure from the expansile schwannoma caused severe lower lateral cartilage and anterior septal atrophy leading to a collapsed and expanded nasal tip after resection. To correct this, a total reconstruction of the anterior tip complex was done using combined ear cartilage seagull wing graft, shield graft and septal extension graft. Conclusion: Nasal tip and septal schwannoma is rare and can cause significant nasal obstruction and deformity. Complete excision is vital to avoid recurrence. Total reconstruction of the lower lateral cartilages using autologous septal and ear cartilage grafts may be a safe and effective technique that yields acceptable aesthetic results.
