Management of Nasal Dermoid Sinus Cyst by Modified Bipedicle Advancement Flap Technique

Abstract

ABSTRACT Midline congenital nasal lesions are rarely encountered in adults. Nasal dermoid sinus cysts (NDSC) account for 1 to 3% of dermoid cysts overall and 11 to 12% of head and neck dermoids. Most lesions are diagnosed within the first 3 years of life but in some cases the diagnosis can be delayed. Nasal dermoid sinus cysts are unsightly, prone to infection. Treatment is complete surgical excision. We are presenting a case of 21-year-old man with a NDSC who presented with soft tissue hump over the bony nasal dorsum, recurrent infection and discharge from the two sinus openings over the bony nasal dorsum. We review the embryology of nasal dermoid sinus cysts, discuss their presentation, evaluation and management in adults. Radiological investigations like computed tomography (CT) scan, magnetic resonance imaging (MRI) are essential to know the extension of the sinus tract and CNS involvement. Complete surgical excision and reconstruction of the defect over the bony nasal dorsum by modified bipedicle advancement flap technique will help to give esthetically good looking nose.
