Abstract

This paper is based on a study of 114 lateral nasal walls of adult heads in the fresh state. The position, size, shape and relations of the maxillary ostium were noted. Special attention was paid to its accessibility for sounding and for irrigation. The presence of accessory ostia was sought for and noted.

The situation of the ostium in the posterior portion of the infundibulum ethmoidale where the bulla tapers away on the upper side and the uncinate on the lower side makes it desirable to know these structures, all of which are located under cover of the middle turbinate.

THE UNCINATE PROCESS

The uncinate process of the ethmoid bone is a fine, thin, delicate bony process originating from the anterior medial aspect of the ethmoid labyrinth. It is covered by the middle turbinate and is in relation to the medial and posterior surface of the lacrimal bone.
