Brief Clinical Studies

Antrochoanal polyp is a benign unilateral sinonasal lesion that arises from maxillary sinus and reaches the choana. It is composed of 2 components: the solid nasal division and the antral part which is almost always cystic and single. Proper identification and removal of polyp attachment to the maxillary sinus wall are essential steps to prevent recurrence. We report the first case of a bifid antrochoanal polyp in a 55-year old male patient. The polyp had an attachment to the posteroinferior wall of the maxillary sinus and then divided inside the sinus into 2 branches that exited the sinus through 2 different accessory ostia but only the posterior part reached the choana. The polyp was successfully removed via an endoscopic surgical approach.
