Nasolabial cyst: a retrospective analysis of 18 cases.
Nasolabial cysts are rare but easily identifiable when they do occur. They are thought to arise from the remnants of the nasolacrimal ducts, but most of the available information on these cysts is limited to isolated case reports. The purpose of our study was to examine the clinical and pathologic features of nasolabial cysts in order to provide a basis for their correct diagnosis and treatment. Eighteen patients with nasolabial cysts were treated at Korea University's Guro Hospital between Jan. 1, 1988, and Dec. 31, 1999. We retrospectively analyzed the clinical appearance, pathologic findings, and treatment results in each case. All patients underwent surgery via the sublabial approach. The lining epithelia were identified as either pseudostratified, stratified squamous, or simple cuboidal. A cyst recurred in only one case, and there were no surgical complications on follow-up. The results of our study provide a basis for sound diagnosis and treatment.
