[Surgical therapy of odontogenic maxillary sinusitis. Report on 397 cases].

Operative procedures were carried out on 410 maxillary sinuses in 397 patients. The most frequent indications for surgery were communication between the mouth and the atrium (55.4%) and cysts (24.2%). A Caldwell-Luc operation was carried out in 76.6% of the cases (radical operation). Vestibulum-cheek flaps were used to close the fistula in 97% of the cases. A follow-up examination of 220 patients showed that 10.2% complained of pain. The indications for surgery were limited to avoid this lasting damage.
