A Case of Simultaneous Antrochoanal and Sphenochoanal Polyps / 대한이비인후과학회지

ABSTRACT

Antrochoanal polyps account for four to six percent of all nasal polyps. Sphenochoanal polyps are extremely rare. Coexistence of antrochoanal and sphenochoanal polyp is not reported in Korean literature. We have recently experienced a case of an antrochoanal and an accompanying sphenochoanal polyp that have been successfully managed by endoscopic sinus surgery. Therefore, we present this rare case and review the clinical, radiological, and pathological features.
