ANALYSIS OF COMPLICATIONS OF SURGICAL TREATMENT OF OROANTRAL PERFORATIONS AND FISTULAS

Relevance. Despite the large number of CCA treatment methods available today and the fact that each of these methods is presented as an effective solution to the problem, there is still a high percentage of their recurrence, reaching 9-30%. It becomes obvious that an effective solution to this problem is unlikely without analyzing the causes and factors leading to failures in surgical treatment of CCA. The aim of the study was to increase the effectiveness of surgical treatment of oroantral messages by analyzing the causes of failures of surgical methods of OSA plastic surgery based on our own clinical material. Materials and methods. This study included 61 clinical observations and case histories for the period 2020-2025. The clinical material was based on clinical cases where patients underwent surgical removal of oroantral perforations formed intraoperatively as a result of tooth extraction, odontogenic cysts and jaw neoplasms, as well as plastic surgery of oroantral fistulas, which patients treated both initially and after unsuccessful previous attempts to eliminate oroantral fistula. Patients with recurrent OSA were included in a separate group, since we did not have accurate data on previous operations performed in other medical institutions and could not judge the causes of relapse. Also, these patients after previously unsuccessful surgical interventions had significant morphological differences in the initial state of soft tissues, consisting of cicatricial changes in the mucous membrane in the area of OSA, deficiency of the vestibule of the oral cavity. Results. According to the results of an objective clinical examination, as well as a control CT diagnosis, after 3 months, there was a closure of the oroantral message of the maxillary sinus and oral cavity with complete epithelialization in the postoperative area, as well as the elimination of symptoms of chronic odontogenic maxillary sinusitis.
