Antrochoanal polyps mostly arise from the maxillary sinus and show a relatively high incidence in children and young adults. The base of the antrochoanal polyp is often found on the lateral or posterior wall of the maxillary sinus and extends toward the choana through the nasal cavity. The most important point during surgery for antrochoanal polyp is to remove it completely from its base. For this purpose, endonasal sinus surgery (ESS), combining middle meatal and inferior meatal approaches, is considered the most suitable. In this paper, we report 2 pediatric cases demonstrating antrochoanal polyps successfully treated by combined ESS approaches.
