title: Choanal polyp originating from the cribriform plate.
abstract: A choanal polyp (CP) can be defined as a solitary soft tissue lesion that passes through the sinus ostia and extends toward the choana. Although a CP usually originates from the maxillary sinus, unusual origins have been reported. Diagnosis of a CP is made by endoscopic and radiologic examinations. Computed tomography and magnetic resonance imaging are very helpful to detect the origin and the extent of the polyp. Endoscopic examination may as well demonstrate the exact site of CP origin. Functional endoscopic surgery is the treatment of choice. Excision of the CP at the exact location of the origin is generally satisfactory. The prognosis after the surgery is good, and recurrence rate is low. Herein, we present a case of a CP originating from the cribriform plate with its radiologic and surgical findings.
