Morphological changes in the maxillary sinus after the anterior wall had been reconstructed in a radical antrum operation for odontogenic sinusitis were evaluated in 24 patients. In nine patients, the bone replacement of the anterior wall was fixed by using synthetic absorbable surgical sutures. In the remaining 15 patients, the bone replacement was fixed by using a titanium micro-plate. We compared these two techniques for fixation. No patient in either group complained of any clinical problems since the radical antrum operation. However, the bone replacement was absorbed only in 4 of the 24 patients. Some of the other patients had a depression in the inner side of the maxillary sinus, scar tissue in the sinus, or both. Hence, we undertook quantitative analysis by computed tomography to evaluate the depression of the anterior wall and the scar tissue on the maxillary sinus in the different fixation groups. Bone depression of the anterior wall and the amount of scar tissue were slightly greater in the synthetic absorbable surgical suture fixation group than in the titanium micro-plate fixation group. These findings suggest that titanium micro-plates are particularly useful for fixation of the anterior wall of the maxillary sinus.
