Common causes of odontogenic sinusitis include dental abscesses and periodontal disease, sinus perforations during tooth extraction, or irritation and secondary infection caused by intra-antral foreign bodies. Sinusitis with an odontogenic source accounts for 10-20 percent of all cases of maxillary sinusitis.
The possibility of odontogenic sinusitis should always be considered when a patient has unilateral symptoms like purulent rhinorhoea. The appropriate work-up includes a history of dental treatment, radiological examination, and dental examinations.
A combination of medical and surgical approaches is generally required for the treatment of odontogenic sinusitis. A consultation between the ENT Surgeon and the dentist is important in dealing with odontogenic sinusitis.
