Clinical and radiological characteristics of maxillary sinusitis caused by teeth at the Department of Dentistry and Maxillofacial Surgery, Hai Phong University of Medicine and Pharmacy Hospital

Abstract

Objectives: Describe the clinical and paraclinical characteristics of odontogenic sinusitis, evaluate the treatment results of odontogenic sinusitis. Methods: Cross-sectional descriptive study on 30 patients diagnosed with odontogenic sinusitis. On cone beam computed tomography (CBCT), it is necessary to detect important signs that point to the cause of odontogenic sinusitis, such as ipsilateral maxillary sinus opacity and periapical inflammation, and periapical bone loss. Cone beam computed tomography is valuable in diagnosing maxillary sinus lesions and assessing in detail the causative tooth lesions, helping to plan combined sinus and tooth treatment. Results: showed that facial pain accounted for 90.6%, ipsilateral maxillary toothache accounted for 90.6%. Partial ipsilateral maxillary sinus opacity accounted for 62.5%, periapical inflammation accounted for 87.5%, periapical bone loss accounted for 84.4%. Thus, maxillary sinusitis due to teeth has two very valuable suggestive symptoms: facial pain and ipsilateral maxillary toothache. Treatment results: 100% of patients had stable maxillary sinus during dental treatment.
