XXXX with bioactive glass.

@entity1 @entity12476 @entity50
BACKGROUND: Bioactive glass (BG) is a glass ceramic material. It has been used as surgical bone replacement material in ear and oral surgery, orthopedics, and dentistry. METHODS: Bioactive glass was used as obliteration material in a series of @entity50 on 10 @entity1 suffering from @entity12476 , which other, more-conservative treatment modalities had failed to cure. RESULTS: Bioactive glass is easy to handle, and complete obliteration of all sinusal recesses and excavations is easily achieved. No adverse effects of the implant material have been seen over a mean follow-up period of 5.0 years. One @entity1 with a local recurrent infection in the outer table of the sinus was reoperated on 5 months after primary surgery. Repeated postoperative computed tomographic scans analyzed by digital region-of-interest (ROI) selection showed no remarkable changes in the frontal sinus cavities but a slight, yearly decrease in the density of the occlusion material. Laboratory monitoring of @entity1 and histopathologic examination of two postoperative biopsy specimens indicated that the material is well tolerated and stable. CONCLUSIONS: Bioactive glass is a promising and well-tolerated bone graft suitable for @entity50 . Total accurate obliteration of the sinus is achieved with different sizes of granules and blocks. The results of the obliteration are maintained owing to the stability of the material.
