A case of odontogenic sinusitis resulting in marked ophthalmologic symptoms

Odontogenic sinusitis is induced due to the anatomical relation between the maxillary sinus basis and the maxillary molar teeth, which is already well-known. On the other hand, it is also known that inflammation in the maxillary sinus involves the orbita to cause disorders owing to the anatomical relation with relatively thin osteal wall separating the maxillary sinus and the orbita, but it seems relatively rare that odontogenic sinusitis is associated with symptoms such as exophthalmos and diplopia, etc. In the present paper we report, with some considerations, a case of right odontogenic sinusitis resulting in marked ophthalmologic symptoms which we recently experienced.Our subject was a 34-year-old male. He left pain at the right maxillary molar region about 3 weeks before the first visit to our hospital. The pain intensified with the appearance of cold symptoms 2 days before the first visit. On the first visit, we found swelling in the right maxillary, cheek, and orbital regions, and he was hospitalized. Ophthalmologic symptoms included exophthalmos, palpebral swelling, diplopia, and narrowed visual field, etc., were improved after the antiinflammatory treatment. Five months have passed since extraction of causative teeth and radical operation for sinusitis with a favorable course without relapse.
