Evaluating Single-step Functional Sinus Endoscopy and Transoral Surgery for Treating Odontogenic Maxillary Sinusitis

What this Trial Is About

Maxillary sinusitis caused by dental or dento-alveolar structural problems, known as odontogenic maxillary sinusitis OMS, requires a distinct treatment approach compared to other types of sinusitis. This condition involves different causes, diagnosis, and treatments, and there is no clear consensus among specialists such as otolaryngologists, maxillofacial surgeons, and dentists on the best treatment method or which specialist should lead the care. This study aims to evaluate the effectiveness of a combined approach using Single-step Functional Sinus Endoscopy and transoral surgery for treating OMS through an integrated departmental therapy. Participants will be treated in one of three groups the combined Single-step Functional Sinus Endoscopy and transoral surgery group, where functional sinus endoscopy is performed by an otolaryngologist and transoral surgery by an oral and maxillofacial surgeon in the same visit a group treated only with functional sinus endoscopy by the otolaryngologist and a group treated only with transoral surgery by the oral and maxillofacial surgeon. The transoral procedures involve tooth extraction, fistula closure, or cyst removal, while the sinus endoscopy involves cleaning and irrigating the sinus under general anesthesia. Throughout the study, participants will be monitored by measuring the thickness of the sinus mucosa at two weeks, one month, and three months after the intervention. Clinical, radiographic, and endoscopic sinus surgery ESS data will be collected to assess outcomes. The research team will use these measurements to evaluate treatment effectiveness and safety. The study is randomized and double-blinded, with an expected completion date in July 2027.
