A Case of Endoscopic Approach of Epidermoid Cyst Arising in the Inner Surface of Nasal Bone / 대한이비인후과학회지

ABSTRACT

The midline dermoid cysts are rare congenital lesions that occur either solitary or in association with various craniofacial disorders. The growth of these lesions can cause nasal and midfacial disfigurement, recurrent localized infection, and symptoms consistent with an intranasal lesion (e.g., obstruction). Complete excision is necessary, otherwise the epithelial-lined tract (s) can regenerate, often resulting in chronic drainage and intermittent infection. We present an unusual case of congenital midline nasal epidermoid cyst in an 19-year-old girl for whom no radiographic evidence of transcranial extension was found. Transnasal endoscopic access without craniotomy was used to remove the epidermoid cyst arising in the inner surface of nasal bone.
