Abstract
In order to prevent the transformation or deformation of the maxillary sinus after radical operation we tried a new method, namely the opening of the anterior wall of the antrum was sewed up with periosteum of facial wall. This method produced good condition of the wound to hold cave-healing of the maxillary sinus.
Nine cases of sinuitis were treated by this method and the radiographic and tomographic examination after the surgery showed satisfactory results.
