Surgical anatomy of lateral nasal wall in northeast Thai cadavers.

A morphometric osteological study of the lateral nasal wall of Thai cadavers proved essential for the endoscopic sinus surgery on Thai patients in order to increase effectiveness and decrease the number of intraoperative complications. The middle turbinate should be preserved during the operation because it is a useful landmark for finding the natural maxillary sinus ostium and for avoiding nasolacrimal duct injury.
