A new transnasal approach to nasolabial cyst: endoscopic excision of nasolabial cyst.

Nasolabial cyst (NC) is one of the midface lesions that are seen rarely. Nasolabial cyst is generally seen in females typically on the fourth and fifth decades and localized unilaterally. Diagnosis usually depends on clinical evaluation. Sublabial excision is the classic method, but endoscopic marsupialization is suggested in current literature. An NC that is totally excised endoscopically is introduced in this article. This is the first case of NC excised endoscopically that is described in English literature.
