Abstract
|
|
|
|
An accessory ostium can be found in the posterior fontanelle of the maxillary sinus during endoscopic examination of the nasal cavity in approximately one quarter of patients. It is not uncommon to find an accessory ostium in a CT scan. Recently, we removed a polyp from inferior meatus of a thirteenyears old girl. After polypectomy, we found accessory ostium of maxillary sinus in the inferior meatus. As far as we know, this is the first case of ectopic accessory ostium of maxillary sinus.
