•The endoscopic approach is considered safe and effective procedure.•Endoscopic large middle meatal antrostomy has a low recurrence rate in antrochoanal polyps.•The antral portion of ACP should be removed, together with the periostium on the point of origin.•The development of endoscopic naso-sinusal instrumentation allows the best control of the site origin of the ACP. The Endoscopic approach for complete removal of antrochoanal polyp is considered a safe and effective procedure with the best control of the attachments of antrochoanal polyps. The mains of our study are to review the clinical features and evaluate the recurrence in the patients affected by antrochoanal polyps (ACPs) and surgically treated by endoscopic middle meatal antrostomy. The present research is a retrospective study. it includes the clinical data of subjects affected by ACPs, and referred to ENT Department, Face and Neck Surgery, Hospital 20 August 1953, between January 2016 and January 2019. All patients have been treated surgically with endoscopic middle meatal antrostomy under general anesthesia. Recurrence occurred in 3 cases (12%), in these three recurrent cases, the site of attachment originated from the lateral wall. FESS was the first-choice treatment for APCs in the present series; our recurrence rate was encouraged for the practice of the endonasal endoscopic approach. A focus on the detection of the exact origin of the polyp and the resection of the periostium on the point of attachment considered the key to prevent recurrence.
