ANATOMY, PHYSIOLOGY AND EMBRYOLOGY
Myerson1 examined 114 specimens of lateral nasal walls. Measurements were made to ascertain the size, shape, direction and relations of the maxillary ostium. Accessory ostia were also studied in a like manner. It was noted that the orifice lies in a horizontal, vertical or oblique position. The posterior angle formed between the bulla and the uncinate process was found to be the most constant guide to the approach to the orifice. Numerous tables and drawings showing the results of this study are presented. The study was undertaken to establish the practicability or impracticability of irrigating the antrum through the natural opening.The anatomy of the maxillary antrum is reviewed by Wells.2 Special emphasis is placed on its relationship to the teeth. The developmental variations, nerve and blood supply and anatomy of adjacent structures are taken up in detail.Wenner demonstrated that when aqueous solutions
