RESUMEN
BACKGROUND: Odontogenic sinusitis is an underdiagnosed entity and is one cause of failure of conventional treatments of sinusitis. Unfortunately, there is no consensus so far on the best management protocol. This retrospective study aimed to suggest a practical management protocol that can reduce misdiagnosis and improve treatment outcomes. METHODS: The study included 74 patients with confirmed odontogenic sinusitis who were diagnosed and treated over 10 years (2010-2019). The patient data were recorded and analysed. RESULTS: Dental pain was reported in only 31.1 per cent of patients. Fifty-six patients (75.7 per cent) had received dental treatment during the last year, but only 13 (23.1 per cent) reported it. Dental pathology was missed on initial computed tomography evaluation in 24 patients (32.4 per cent). Forty-one patients (55.4 per cent) were successfully treated by dental procedures and antibiotics. Fourteen patients needed functional endoscopic sinus surgery in addition to dental procedures. CONCLUSION: Successful management of odontogenic sinusitis requires good communication between rhinologists, radiologists and dentists. Dental treatment should be the logical first step in the treatment protocol, unless otherwise indicated.
