Investigation of dental maxillary sinusitis cases treated with endoscopic endonasal sinus surgery

Abstract

We examined cases of dental maxillary sinusitis in patients treated with endoscopic endonasalsinus surgery (ESS). Even in patients with dental maxillary sinusitis, inflammation was confined to half or less of the maxillary sinus, and more than half of the patients had inflammation spreading to other paranasal sinuses. In addition, in most cases, lower and middle nasal turbinate formation, nasal septum remediation, and other nasal cavity improvement proce. Furthermore, in 3 of the 6 patients diagnosed with apical periodontitis, the symptoms did not improve with tooth extraction alone, and ESS was performed after tooth extraction. ESS, which treats multiple paranasal sinuses at the same time and can be simultaneously combined with nasal cavity improvement procedures, is useful for treating dental maxillary sinusitis that does not show improvement with conservative treatment.
