Operative treatment of frontal sinusitis

Abstract

When the medical therapy fails trephination is the primary operation indicated in acute eroding sinusitis when drainage is necessary to avoid severe complications. In recent years also endoscopic transnasal surgery has been recommended for exenteration of the underlying disease in the ostiomeatal unit as well as for opening of the obstructed nasofrontal duct in acute phase of the disease. In Turku University Central Hospital endoscopic frontal sinus surgery is still reserved for cases with prolonged or delayed disease performed as a secondary operation after trephination and CT examination. Failures are common after these operations and both types of surgical treatment may be needed. Three percent of our patients developed a persistent chronic infection inside the frontal sinus. In these cases external osteoplastic approach is recommended. In these operations we have used bioactive glass as obliteration material with promising clinical results.
