REPORT ON RESULTS OF FRONTAL-SINUS OBLITERATIONS IN TURKU-UNIVERSITY-CENTRAL-HOSPITAL 1977-1994

When a sinusitis develops into a chronic stage, for which endoscopic s inus surgery is not radical or succesfull enough, we currently perform in our hospital obliteration of the infected frontal sinuses. The pre sent study is a partly retrospective and partly prospective evaluation of the outcome of patients operated on by osteoplastic approach. Obli teration materials used during years 1977-1994 have been ossar, collag en matrix and since 1990 bioactive glass. Although major differences b etween the obliteration materials could not be demonstrated the oblite ration with bioactive glass has proven to be a safe and effective meth od for patients who did not show any improvement after endoscopic sinu s surgery.
