NASOLABIAL CYSTS: ABOUT 11 CASES.

Introduction:Thenasolabial cyst is a non-odontogenic lesion, uncommon of the area of the nostril wing. Few publications were interested in studying the management of this lesion. The objective of our study is to describe the pre-operative aspects and the results of our management of nasolabial cysts and analyse the pre-operative factors influencing these results. Materials and methods:This was a retrospective study between December 2010 and December 2018 collected in our tertiary hospital structure. It concerned patients operated for a nasolabial cyst confirmed by the anatomo-pathological study. Surgical treatment was performed under general anesthesiabytransoral vestibular approach. Results:Eleven cases were collected. The cysts were unilateral and located on the left in 9 cases. The median diameter of the cyst was 2,5cm. The cyst?s exeresis was complete in all the cases. The accidental breach of the nasal mucosa occurred in 2 cases. Procedure time had a median of 30 minutes. A significant difference in time was observed in case of mucous breach (p = 0.03). The immediate postoperative follow-up was simple. After a median of 15 months, there were no cases of oral fistula or recurrence. Discussion / Conclusion:Thenasolabial cyst is an uncommon benign pathology, currently better known. The literature reported several surgical techniques. Vestibular enucleation remains an accessible method with low morbidity.
