[Clinical classification of chronic odontogenic maxillary sinusitis].

Examination of 248 patients with odontogenic maxillary sinusitis (OMS) has shown that most of OMS forms run a chronic course. Their clinical classification is outlined with a special emphasis on the latent form which occurs in 16.5% of the examinees. An open form of OMS was diagnosed in 51.6% of the patients. Treatment of chronic OMS is surgical in many cases: maxillary sinusotomy with upper jaw teeth examination and treatment.
