Surgical approach to oroantral communication due to residual root intrusion in the Maxillary Sinus - Case Report

The maxillary sinuses are pneumatic pyramidal cavities that can extend to the alveolar process, creating an intimate relationship between the root apex of the upper posterior teeth and its floor; therefore, in tooth extraction procedures, care must be taken not to generate a communication between the maxillary sinus and the intraoral environment, making it a route of infection. This work aims to show the dental community a form of treatment for oroantral communication induced by residual root intrusion in the maxillary sinus. Female patient, Caucasian, 53 years old, attended the Integrated Dental Clinic of the Dental School of Presidente Prudente, complaining of air coming out of the mouth. After anamnesis, clinical examination and radiographic examination, an oroantral communication was diagnosed in the region corresponding to tooth 26, due to intrusion of a residual root into the maxillary sinus. After clarifying the diagnosis and prognosis and signing the free and informed consent term, she will be submitted to the surgical procedure to close the oroantral communication and subsequent removal of the residual root inside the maxillary sinus. Due to the possibility that such an accident may occur via surgical procedures, especially when extracting posterior elements, it is of great importance for the dental surgeon to have complete mastery over the anatomy, as well as to have radiographic exams at hand that will help him throughout the entire procedure. the process. Take special care when removing first molars and, if you suspect that you may have ruptured the sinus floor, be aware of the Valsalva technique.
