The study will be offered to patients for whom chronic maxillary sinusitis will be diagnosed in the first ENT (ear, nose and throat) consultation. These patients will then be seen in a stomatology consultation to determine whether or not a dental cause is objective


Chronic maxillary sinusitis is an inflammatory condition and/or infectious diseases of the maxillary sinus, which last longer than 12 weeks. Those whose the origin is dental, are well described, and yet under-diagnosed most of the time due to a lack of well-defined diagnostic criteria and literature. There is controversy in the various studies about their prevalence. Their management and in particular the therapeutic sequence, is not the subject of any recommendation and involves only a few clinical studies. Their consequences on the patient's general health and quality of life are important. The lack of knowledge about them often leads to diagnostic errors and therefore to a persistence of symptomatology. Moreover, their complications when they are not or incorrectly treated, although rare, can be dramatic (occulo-orbital or endo-cranial complications for example).

Preliminary work in the form of a retrospective study was carried out within of the Centre Hospitalier intercommunal de Crteil in 2015. In view of the results the investigators wanted to set up a clinical trial with the following objectives measure the prevalence of chronic maxillary sinusitis of dental origin and measure the effectiveness of exclusive dental and medical treatment, which could avoid surgical intervention under general anaesthesia, at the higher morbidity.
