Cisto nasolabial: aspectos diagnósticos e terapêuticos

nasolabial cyst is a rare lesion situated behind the ala nasi, extending backwards into the inferior nasal meatus and forward into the labio-gingival sulcus. aim: we present our case of a nasolabial cyst, with the purpose of discussing clinical presentation, diagnosis and the more suitable surgical techniques to treat this disorder. materials and methods: a retrospective study of eight patients with diagnosis of nasolabial cyst, carried out in the period of january/2000 to december/2006. the diagnosis was suggested by otorhinolaryngology exam and computer tomography. all patients were submitted to surgical treatment (enucleation) and definitive diagnosis was confirmed by histopathology. results: predominant symptoms were nasal obstruction, swelling in the nasal vestibule region and local pain. patients had had symptoms for a median of 26.2 months. ct scan was performed in all patients, showing a well outlined cystic lesion with bone remodeling in some cases. median sizes of the cysts were 2.18cm. there was no evidence of recurrence during a mean follow-up of 19.5 months. conclusion: nasolabial cysts are rare lesions. common presentation is a well-confined swelling, local pain and nasal obstruction. enucleation is the treatment of choice with low recurrence rate.
