Managing nasolabial cyst: Experience at a tertiary care teaching hospital in Eastern India

Abstract

Abstract Background: Nasolabial cysts are non-odontogenic cysts that arise from the nasal alar area. Sublabial resection of the nasolabial cyst is considered an effective surgical modality of treatment. Objective: This study aimed to evaluate the clinical presentation, diagnosis and treatment of nasolabial cyst at a tertiary care teaching hospital in eastern India. Methods: This was a retrospective study of 38 cases of nasolabial cysts managed between May 2018 and June 2022. The detailed clinical presentations, investigations and treatment of nasolabial cysts of the patients were studied. Results: Out of 38 cases of the nasolabial cyst, 22 (57.9%) were seen on the left side, 13 (34.2%) were seen on the right side and 3 were seen bilaterally. The most common presenting complaint was facial swelling (84.2%). Computed tomography of the nose and paranasal sinuses was done in 24/38 (70.5%) patients studied. Surgical excision of the nasolabial cysts was done by intraoral sublabial approach in 32 (84.2%) cases and 6 underwent endoscopic transnasal marsupialisation. The most common post-operative complication was post-operative facial/perinasal swelling. One case of recurrence was reported who underwent endoscopic transnasal marsupialisation. Conclusions: Nasolabial cysts are an uncommon clinical entity but manifest cosmetic deformity and nasal obstruction. Intraoral sublabial excision and endoscopic transnasal marsupialisation are important surgical techniques for the nasolabial cyst. The post-operative complications and chance of recurrence are rare.
