How to avoid the rhinological complications of subantral plasty

Background. Subantral plasty is widely known as a reliable way to compensate for the lack of bone tissue in severe atrophy of the alveolar process of maxilla. The main cause of odontogenic maxillary sinusitis after subantral plasty is considered to be insufficient work of the natural anastomosis of the maxillary sinus. Objective. Improvement of the effectiveness of prevention and treatment of odontogenic maxillary sinusitis during subantral plasty. Methods. The study included 113 patients undergoing treatment with a dentist for maxillary adentia (61 men and 52 women). The patients’ age ranged from 28 to 67years (mean age 43.5±3.2 years). The patients were divided into three groups. Results. In this study, we evaluated the results of computed tomography (CT) of the paranasal sinuses of patients who underwent and were planning for reconstructive surgeries on the alveolar process of maxilla. Comparing the results of CT scan of the paranasal sinuses and endoscopic examination of the nasal cavity of patients included in the study, it can be concluded that the most likely cause of odontogenic maxillary sinusitis after subantral plasty of patients was severe disturbances in the anatomical structure of the nasal cavity. Conclusion. A detailed patient’s medical history and assessment of the ostiomeatal complex using endoscopic examination of the nasal cavity are crucial for reducing postoperative rhinological complications after subantral plasty. It is necessary to assess the condition of the paranasal sinuses in patients who are planning for dental treatment for maxillary adentia.
