Objective: To evaluate the characteristics of antrochoanal polyps (ACPs) in children., Methods: 10 children operated for ACP were investigated retrospectively. Demographic characteristics, surgical and histopathological findings were evaluated., Results: The mean age was 10.2 years. The antral part of ACP was removed through middle meatal antrostomy in four patients, and transcanine sinuscopy was needed in six patients. It was found that the polyp passed through the main ostium in seven patients and accessory ostium in three patients. The antral part of the polyp was found to be cystic in six patients and polypoid in four patients. There was recurrence of polyps during follow-up period in two cases in which antral part of the polyp was seen to be removed through middle meatal antrostomy during primary surgery. In histologic examination, prominent eosinophilia was detected only in one patient and no mucous gland was detected in any patient., Conclusion: Endoscopic surgery through the middle meatal antrostomy combined with transcanine sinuscopy ensures the complete removal of the antral part of ACP in children.
