Effects of Preoperative Tooth Extraction on Surgery for Odontogenic Maxillary Sinusitis

Abstract

There are no established standards or guidelines for the treatment strategy for odontogenic maxillary sinusitis. Endoscopic sinus surgery (ESS) may be difficult to perform due to the inflammatory nature of the procedure if preoperative dental treatment is inadequate. In addition, postoperative recurrence is also a concern because the etiology remains. In this study, we divided patients into two groups: those who had preoperative extraction of the root cause teeth (6 cases) and those who had dental treatment other than tooth extraction (10 cases), and retrospectively evaluated the operation time, amount of blood loss, and postoperative recurrence. There were no significant differences in operative time, blood loss and postoperative recurrence between the groups. Thus, tooth extraction is not always necessary for safe surgery, and preservation of the causative tooth may be an option. The otolaryngologist should continue to monitor the nasal sinuses after ESS because maxillary sinusitis may recur with or without tooth extraction. It is important for otolaryngology and dentistry to work closely together for appropriate treatment of odontogenic maxillary sinusitis since this disease involves both fields.
