El-Kady MD and Ahmed Hussein Ahmed MD Depatment ofOtorhinolaryngology, Benha Faculty of medicine, Egypt Abstract Many alloplastic materials have been used in clinical frontal sinus obliteration. It has been difficult to find reliable obliteration material with¬out short- or long term complications. Most common problem in frontal si¬nus obliteration is the resorption of occlusion material. This study was made to evaluate the efficacy ofBioglass as an alternative to autologous fat in the obliteration of the frontal sinus. Standard surgical techniques were used to obliterate the frontal sinus. Eight patients underwent Bio-glass frontal sinus obliteration. There were 2 women and 6 men in the series with age ranges from 30 to 55 (mean, 38years). Two patients un¬derwent obliteration for chronic infections with mucopyocele. Follow-up radiographs were obtained at3, 6 and 12 months after obliteration of the sinus with Bioglass. No patient has developed clinical or radiographic evi¬dence of recurrent frontal sinusitis. No implant has been rejected . Seven patients reported complete resolution of all symptoms. Bioglass had dem¬onstrated efficacy in obliteration of frontal sinus. The material has the ad¬vantage that it takes well,no reaction or rejection and it is also of rea¬sonable expense. The obstruction of the frontonasal duct by this material was ensured. Bioglass offers the advantages of no donor site morbidity and the potential for complete osseointegration.
