Odontogenic Sinusitis Caused by an Inflammation of a Dentigerous Cyst and Subsequent Finding of a Fibrous Dysplasia. A Case Report

The Open Dentistry Journal 30 Nov 2016 CASE REPORT DOI: 10.2174/1874210601610010647


We report the case of a 38-year old male patient with sinusitis caused by an infected follicular cyst due to an ectopic impacted third molar in the right maxillary sinus.

A 10-day antibiotherapy regimen was administered; subsequently, the cyst and the third molar were removed achieving complete recovery.

Fibrous dysplasia was diagnosed at follow-up examination (occupation of the maxillary sinus by bone tissue was observed in a radiographic examination) and confirmed by biopsy.

In cases of odontogenic sinusitis, thorough examination is crucial, as evidenced by the case reported in this study.

A Literature review was performed in order to identify the diagnostic methods currently available and the clinical features, complications and treatment for both, odontogenic maxillary sinusitis and fibrous dysplasia.
