The frequency of the development of a maxillary odontogenic sinusitis acording to various sings and standarts

According to statistics, among sinusitis of various etiologies, the frequency of odontogenic maxillary sinusitis averages from 26 to 40%. This disease affects mainly people of working age and occupies a signiticant place in the practice of a dental surgeon.Aim of the study was to analyze the frequency of occurrence of odontogenic sinusitis in the practice of a dentist- surgeon, tactics and principles of treating patients in an inpatient setting.Materials andmethods. The article presents the results of a retrospective epidemiological analysis of the incidence according to the case reports (70 case reports of inpatients) and records of surgical intervention of the Department of Maxillofacial Surgery in the Ivanovo Regional Clinical Hospital from 2016 to 2019.Results. In total, during the study period, 21 patients addressed chronic odontogenic sinusitis in the exacerbation stage and out of exacerbation, among them 12 (57%) men and 9 (43%) women. This pathology mainly affects men aged 40 to 50 years. The highest percentage of occurrence as a causative tooth was 1 molar - 76 ± 0.25%, 2 premolar, 2 and 3 molars, respectively in 5 ± 0.23%, 9 ± 0.20%and 10 ± 0.26% of cases (p < 0.001). The quantitative indicator of the period of hospitalization of patients in the hospital averaged 9.4 bed days. A total of 22 patients referred to chronic perforated sinusitis, among them 10 (45%) men and 12 (55%) women. Pathology is prevalent mainly among women 5060 years old. When analyzing causal teeth in the development of chronic perforated sinusitis, the highest percentage of occurrence as a causative tooth of 1 molar was also recorded - 67 ± 0.21%, the hospitalization period in the hospital is on average 9.95 bed days. All patients underwent radical maxillary sinusotomy on the right/left, plastic tistula. About 27 maxillary cysts related to the maxillary sinus, 27patients, among them 16 men and 11 women, came. Moreover, 22 (81%) patients had a root cyst, 4(15%) had a follicular from the third molar, and 1 (4%) had a malformation. The examined patients had Hxed teeth whose roots stand in the cavity of the cyst. Cysts occur in patients at almost any age, more often men suffer, the hospitalization period in the hospital averages 8.8 bed days.Conclusions. Women aged 50 to 60 years are more likely to suffer from chronic perforated sinusitis, and men from 30 to 60 years old are most prone to the formation of cysts that have grown into the maxillary sinus. In most cases, for all 3 nosological forms of the disease, the tirst molar was the causative tooth. When the maxillary sinus was involved in the inflammatory process, a radical sinusotomy was predominantly performed, significantly reducing the frequency of relapses
