Dentogenic Maxillary Sinus Infections

Dentogenic Sinusitis maxillaris (maxillary sinus infection)

Dentogenic (coming from the dental system) maxillary sinusitis results mostly from an infection in the mouth area over an antrum perforation.

Such infection may result from a tooth extraction in the upper jaw. In case of no previous maxillary sinus infections, the antrum perforation should be closed (plastically covered) immediately, if possible during the same session.   

Otherwise it is inevitable that the described maxillary sinus infection will  result. A plastic covering of the antrum perforation on its own will not then be sufficient.

Most often, the maxillary sinus needs to be surgically drained through the installation of a "nasal window" . Additionally, antibiotics and decongestant nose drops are prescribed and, to prevent another antrum perforation, the patient must not blow his nose.

A dentogenic maxillary sinus infection can also be caused by an inflammatory process in the dental root top area. In this case, the tooth must be treated accordingly (e.g. root amputation) or it must be extracted, where the risk of an antrum perforation is higher.

Mucoceles (mucoid cysts) in the maxillary sinus

Asymptomatic mucoceles are not surgically treated. In case of any symptoms, the mucoceles will be endoscopically removed. Dentogenic mucoceles are relatively rare.
