Prevention of complications after sinus lift surgery

During the study 134 patients with atrophy of the alveolar process of the upper jaw and defects of the dentition were examined before performing sinuslifting and dental implantation. At the stage of preparation for sinus-lifting, additional endoscopic rhinoscopy and computed tomography of the upper jaw with the inclusion of the ostiomeatal complex and the paranasal sinuses were undertaken. The relationship of the initial results of clinical, tomographic and endoscopic studies with the development of complications of the intra- and postoperative period was studied. It has been established that risk factors for perforation of the mucous membrane of the maxillary sinus floor (MS) with open sinus-lifting include MS deformity in the form of bone septa, anamnestic indication of endonasal sinusotomy, functional endoscopic rhinosinus surgery, prior to sinus-lifting, after the procedure, after the sinus-lifting, the procedure is followed by a 5% lifting procedure. For the development of postoperative purulent sinusitis, the significant risk factors are the pathology of the hooked process with narrowing of the anastomosis of the MS and edema of the mucous membrane of the ostiomeatal complex, odontogenic sinusitis, and maximoethmoiditis in the preoperative stage.
