<p>Management of acute sinusitis secondary to minor maxillary sinus exposures<br>Lieutenant Commander Bradley R. Ross, DC, USN, Commander Terry D. Webb, DC, USN, and Commander Michael A. Steinle, DC, USN<br><br><br>Introduction<br>Perforation of the maxillary sinus, or antrum of Highmore, can occur during surgical procedures of the posterior maxillary teeth including extraction, root-end surgery, or periodontal procedures. Proper management of the perforation is essential to prevent infection, chronic sinusitis, or oroantral fistula formation. The purpose of this Clinical Update is to describe the anatomy of the maxillary sinus, discuss prevention and management of minor sinus perfora-tions, delineate acute and chronic sinusitis, and describe when to refer to the oral and maxillofacial surgeon (OS) or otolaryngologist (ENT).
