Peele1 studied the sphenoid sinuses in 139 cadavers and reports on the various anomalies in size, extensions, location of intersinus septum, ostium, and relationship to adjacent structures. Fifteen photographs are presented to illustrate some of these points. The extreme variations encountered in most of the specimens makes it almost impossible to discover a truly normal pair of sinuses.
