Abstract
- Although augmentation of the maxillary sinus floor with autogenous bone grafts has become a well established preimplantology procedure, its effect on the function of the maxillary sinus has not been the subject of prospective human studies. In this prospective study the effects of sinus floor augmentation on maxillary sinus performance were evaluated. Seventeen consecutive patients who were to undergo augmentation of the maxillary sinus floor with an iliac crest autogenous bone graft agreed to participate in this study. All patients were subject to (i) extensive anamnestic and clinical investigation on sinusitis, (ii) conventional radiography (Waters' projection) and (iii) unilateral endoscopic inspection of the maxillary sinus. This triad of evaluations was performed preoperatively, immediately preceding the augmentation procedure (the maxillary sinus to be inspected endoscopically was randomly selected), and at 3 (at insertion of the implants) and 9 months (at uncovering of implants) postaugmentation. None of the 17 patients showed clinical or radiological signs of actual sinus pathology preoperatively, though 5 patients had a history of an impeded sinus clearance. By contrast, unilateral endoscopic evaluation revealed pre-existing subclinical mucosal pathology in two out of five patients with a history of sinus clearance impairment and in one out of the other 12 patients. At 3 months' postaugmentation, clinical and radiographical examination showed chronic maxillary sinusitis in one non-compromised patient. Moreover, serial unilateral endoscopic evaluation revealed subclinical maxillary mucosal pathology in four other patients (two of whom had a history of an impeded sinus clearance), confirmed by Waters' projection in three of these four patients. At 9 months' postaugmentation, only subclinical maxillary mucosal pathology was detected endoscopically in two patients (one compromised, one non-compromised patient), confirmed by Waters' projection in this last patient. Five implants were lost during the 9-month observation period. As is obvious from this prospective evaluation, the effects of the augmentation procedure on maxillary sinus performance in patients without signs of maxillary sinusitis are of no clinical significance.
