Surgical outcomes between two endoscopic approaches for maxillary cysts

Abstract Objective: To compare recurrence rates and symptomatic relief in symptomatic maxillary sinus Retention Cysts (RCs) between Middle Meatus Antrostomy (MMA) alone and Inferior Meatus Antrostomy (IMA) with basal mucosa electrocoagulation. Methods: Patients with symptomatic unilateral maxillary RCs were randomly allocated to MMA (n = 54) and IMA combined with mucosa electrocoagulation (n = 53) groups. Symptomatic relief, cyst recurrence, and closure of the antrostomy opening were compared at 12-months postoperatively. Results: Symptomatic failure occurred in 13 (12.1%) patients, includi...
