Clinical Characteristics of Patients Diagnosed With Odontogenic Rhinosinusitis After Dental Implants.

Background and Objectives: With the ongoing development of intraoral surgical treatment and invasive dental treatments such as implants, odontogenic rhinosinusitis (ORS) is on the rise. ORS related to dental implants accounts for 8% to 37% of cases. The purpose of this study is to define the characteristics of patients with ORS related to dental implants. Methods: From 2015 to 2019, the medical records of 15 patients who developed maxillary sinus disease after receiving dental implants were retrospectively analyzed among patients who visited the ear nose and throat and dentistry departments. We reviewed the chief complaint, assessment, diagnosis, treatment and prognosis of these patients. Results: Of the 15 patients, all were diagnosed with ORS. One patient with a post-operative cheek cyst, 1 with fungal sinusitis, 1 with an inverted papilloma, 1 with chronic rhinosinusitis, and 1 with a radicular cyst were diagnosed after surgery. Endoscopic sinus surgery was performed in 14 patients and 2 patients underwent a combined operation. One patient improved after medical treatment. The follow-up period was about 8.6 months. No recurrence was found in any of the patients. Conclusion: If an implant problem is suspected based on history-taking and physical examination, active consultation with dentistry is needed to diagnose ORS. [ABSTRACT FROM AUTHOR]
