Reconstruction of the Nasal Columella of an Adult Patient with Nasolabial Subcutaneous Island Flap after Resection of a Dermoid Cyst

Abstract

Dermoid cysts located in the nasal region are a kind of congenital lesions and may appear as a nasal swelling in the midline. Although nasal dermoid cysts are usually diagnosed during childhood, they can rarely be detected in adulthood. The most important feature that distinguishes nasal dermoid cysts from other Dermoid cysts of the body is that they can extend into deeper structures in the nose and even into intracranial area. Therefore, it is recommended to perform a good physical examination and a detailed imaging method such as computed tomography and magnetic resonance imaging before the operation. Although the nasolabial island flap is a good option for Columella reconstruction, the flap should be followed-up closely for possible circulation problems.
