ABSTRACT
The study included 564 patients with a deficit in the volume of bone tissue of the alveolar process of the maxillary bone, which did not allow simultaneous installation of crestal implants. The work was carried out relying on modern forecasting systems based on an aggregate and quantitative assessment of the risk of intra- and postoperative complications, anatomical and physiological state of tissues and organs in the area of intervention. In the course of the study, a system for predicting the results of subaxillary augmentation was developed. Factors affecting the nature and frequency of complications in the immediate and long-term postoperative periods are highlighted. A comparative assessment of the functioning of the mucociliary clearance depending on the volume and location of the augmentate is given. Functional methods of investigation – spiral computed tomography and cone-beam computerized tomography – of maxillary bones, video endoscopy of the nasal cavity, study of mucociliary clearance, anterior active rhinomanometry were used. The assessment of the state of the augmentate, pneumatization of the maxillary sinuses, the anatomy of the nasal cavity, paranasal sinuses, the state of the maxillary sinus mucosa, the vertical volume of the walls of the maxillary sinus, and the evacuation capacity of the maxillary sinuses were evaluated. A score was determined for each of the studied parameters. Patterns of preoperative changes in the maxillary sinuses that led to complications in the postoperative period were identified. For each of these parameters, the amount of points collected can range from 1 to 5 points. The higher the score, the higher the probability of successful surgical treatment. If the sum of points is from 1 to 2, forecast of subaxillary augmentation is unfavourable, for 3 points is questionable, with a score of 4–5, the prognosis is favourable.
