PATIENTS AND METHODS: A total of 195 patients of chronic sinusitis were seen in the above centers during this period. Out of these, 18 patients were included in this study who were primarily sinusitis due to odontogenic cause. So the incidence of odontogenic sinusitis was found to be 18/195 or 9.2% in this study. RESULTS: There were 11 male and 7 female patients (1.6:1) with mean age incidence of 41.23 years (± 3.4 years). Unilateral purulent or mucopurulent rhinorrhoea was the most common symptom in this series (13 patients or 76.5%). The most common odontogenic cause for sinusitis was found to be use of different dental implants (6 patients or 33.3%). Involvement of one sided maxillary sinus alone was seen in 13 out of 18 patients (72.2%). The most common tooth responsible for sinusitis was the 2nd molar tooth (8/18 or 44.5%). Endonasal endoscopic sinus surgery was found to be curative in 10 out of 18 patients (55.5%).
