Abstract
|
|
|
The midline nasal 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.
