Abstract

<p>　At present, there is no consensus on the optimal treatment policy for odontogenic maxillary sinusitis. We conducted this prospective study jointly with the department of dentistry to determine the optimal treatment policy for preserving the causative tooth as much as possible. Between 2018 and 2022, 43 cases of odontogenic maxillary sinusitis were enrolled in this prospective study conducted to determine the optimal treatment policy for preserving the causative tooth as much as possible. In the field of otorhinolaryngology, treatment is begun with antibiotic therapy, while in the dentistry field, root canal treatment is performed first. The effect of these conservative treatments were evaluated by CT after 3 months. Endoscopic sinus surgery was performed in cases that failed to show improvement with the above conservative measures. If no improvement was noted even after endoscopic sinus surgery, tooth extraction was performed. This treatment policy allowed the causative tooth to be preserved in 77% of cases. All cases showed improvement after endoscopic sinus surgery. For cases that do not improve with conservative treatment, endoscopic sinus surgery is considered as being a useful surgical option to avoid tooth extraction.</p>
