Abstract

Maxillary sinusitis of dental origin is a rare entity when compared to sinus diseases of rhinogenic origin. It may be caused by the following : oroantral fistula, foreign bodies, periapical granulomas or small inflammatory cysts, and odontogenic cysts occupying the maxillary sinus. In rare cases, antral aspergillosis, following tooth extraction or endodontics, results in symptoms of localized pain, tenderness, and nasal discharge. However, unlike most fungal diseases, aspergillosis is often found without predisposing systemic factors. In such cases, local factors usually predispose patients to this opportunistic infection. More recently, many cases are reported to have been discovered inadvertently after an endoscopic sinus surgery. We experienced a case of fungal sinusitis subsequent to an oroantral fistula following a tooth extraction that was repaired with a simple closure and treated via an endoscopic approach. So we are reporting it with the review of the literature.
