Background: Nasolabial cysts are rare benign epithelial nonodontogenic soft tissue cysts arising in the nasal alar region. Sublabial excision or transnasal endoscopic marsupialization is the standard treatment.

Patients and methods: Between 2019 and 2022, a descriptive retrospective study, including 20 patients who presented with Nasolabial cysts, was conducted.

A retrospective study of patients who were presented in the period from 2019 to 2022, with nasolabial cysts. Patients' files were checked for demographic data, clinical presentation, preoperative radiological investigations, histopathology, surgical approach, complications, and outcome.

Technique:

The surgery is carried out mainly using x5 magnification loupe and 0° degree sinoscope. Submucosal infiltration (lidocaine 2% and 1:100,000 adrenaline). An incision was made at the mucosal covering of the cyst wall and nasal floor in a transverse and anteroposterior direction. The mucosal flap is elevated and separated from the cyst wall and reflected toward the septum side. During dissection, cyst content is usually drained. The whole cyst wall was carefully dissected with sharp and blunt dissection from the mucous membrane, and laterally from the premaxillary area. Finally, endoscopic examination to check the operative bed and refashioning mucosal flap coverage. If mucosal flap is lacerated, then excised and operative bed left for healing by creeping from surrounding edges. Endoscopic trans-nasal complete excision has a shorter operative time, minimal intraoperative bleeding, and no postoperative pain or edema reported.
