A Study of Imaging Diagnosis and Treatment in Odontogenic Sinusitis

Abstract

Odontogenic sinusitis is inflammation of the sinus associated with dental caries and/or periodontal disease. Otorhinolaryngologists, and dentists are involved in the diagnosis and treatment of this disease. In this study, we retrospectively evaluated 42 cases of odontogenic sinusitis that were diagnosed and treated at the Department of Otorhinolaryngology and Dentistry in our hospital. Tooth extraction was required in 25 patients, and 17 patients were curatively treated without tooth extraction. Among the 25 patients who required tooth extraction, 10 underwent ESS and tooth extraction simultaneously, and 6 underwent ESS later because they did not improve with tooth extraction alone. In our study, the presence and size of maxillary sinus perforations were important in determining the indications for tooth extraction. The extent of sinusitis was important in determining the indications for both tooth extraction and ESS. It is necessary for Otorhinolaryngologists and Dentists to cooperate. A prospective study to evaluate and define the optimal treatment for odontogenic sinusitis is warranted.
