Abstract

Objective: This study aimed to evaluate the prevalence of antrochoanal polyps (ACPs) and review the literature. Methods and Materials: We retrospectively studied the clinical presentation and operative records of 100 patients with ACPs treated surgically in August 2008-January 2019 (about 10 years). Age, gender, side, clinical symptoms, associated rhinological finding, a form of surgical treatment, postoperative complication, and recurrence rate were reviewed. Results: From 100 patients, 60% were male and 40% were female. The mean age of patients was 27.4 years (Age range: 8-64). The prevalence of ACPs between other polyps was 19% and between other diseases was 0/4%. The most common symptom was nasal obstruction (96.8%) and after that rhinorrhea (50%). 9.3% had bilateral polyps and 90.7% had unilateral polyps. 100% underwent FESS procedure. 25% had a history of sinusitis and 15% had a history of allergic diseases. The recurrence rate was 3% (3 cases) after an average of 20 months postoperatively. Complication after surgery consisted of mild epistaxis and periorbital edema that were seen in 2%. Conclusion: The results of this study were similar to other studies. This study recommends FESS as a safe and suitable procedure for ACPs. This study also suggests evaluating the relationship between allergy and ACPs in more specific future studies.
