An abnormal foramen connecting the middle cranial fossa with sphenoidal air sinus: A Case Report

Abstract

An abnormal foramen connecting the middle cranial fossa with the sphenoidal air sinus was noted. This foramen was large and circular with a smooth outline. It was located anterolateral to the sella turcica, medial to the superior orbital fissure and behind the optic canal. Since the foramen was noted in a dry skull during osteology demonstration classes, we are unaware about the structures passing though it if any. Knowledge of this foramen may be important for radiologists, endocrinologists and anthropologists.
