Diagnosis of oro-antral communication

Oro-antral communication – accidental opening of the maxillary sinus during surgical interventions, without signs of inflammation. The data of the literature demonstrate the importance of the addressed problem, being a topic of discussion among specialists. Recent studies indicate that 1/5 of patients with OAC are misdiagnosed and only 1/3 are cured after initial treatment. OAC is considered a rare complication of oral surgery, with studies reporting different incidence rates ranging from 0.31% to 13%, and the occurrence of OAC differs depending on the type of tooth that is extracted. The aim of the paper was to study the morbidity structure of OAC patients in outpatient conditions and their application in practice. The given study was carried out within the «Arsenie Guțan» Department of Oral-Maxillo-Facial Surgery and Oral Implantology, of the «Nicolae Testemițanu» State University of Medicine and Pharmacy. In order to achieve the goal and set objectives, 31 patients with OAC who were treated in the surgery office of the Municipal Dental Center in Chisinau during 2022. In conclusion, we mention: The analysis of the specialized literature data propose new diagnostic methods that come to complete and solve the shortcomings of the existing ones. The radiographic examination done before the odontectomy, the post-extraction exploration with a blunt instrument and the very gentle Valsalva maneuver are the keys to success in the diagnosis of oro-sinus communication. OAC is an accident and should be managed promptly to avoid infection of the maxillary sinus.
