Background and Objectives
For maxillary sinus diseases, it is not easily determined whether it is of the sinus or dental origin as the root of a tooth is located in the maxillary sinus; hence the need to find the pathologic origin for better clinical results. The purpose of this study was to define the characteristics of patients who had needed to consult both a dentist and an otolaryngologist with respect to the diagnosis and management. Subjects and Method Thirty-one patients who visited the department of dentistry and ENT between 2014 and 2018 were included in the study. Patients with dental implant sinusitis were excluded. We restrospectively reviewed the medical records for chief complaints, assessment, diagnose, treatment, and prognosis of the patients.
Of 31 patients, 13 patients were diagnosed with odontogenic rhinosinusitis (ORS), 5 with postoperative cheek cyst (POCC), 2 with radicular cyst without ORS, 7 with sinusitis, and 4 with other diseases. Thirteen patients underwent combined operation and 5 at each department. Follow-up periods was about 6.5 months. There was no disease recurrence except one patients with POCC.
There needs to be an active consultation with the dentistry department in case of unilateral sinusitis and past history of dental treatment temporally or when patients show positive findings in CT.
