Patients treated with Maxillofacial Prosthesis have loss of maxillary and/or mandibular substances. Few data are available on quality of life of these patients and its association with some of their socio-demographic, medical and clinical characteristics.

Patients treated with Maxillofacial Prosthesis have loss of maxillary and/or mandibular substances (oral-nasal or oral-sinusal communication, removal of the soft palate, removal of part of the lower jaw). These losses are mainly due to the surgical consequences of cancers of the upper aerodigestive tract, trauma or sequelae of labio-palate clefts. Depending on the etiology of substance loss, there are 3 main therapeutics: surgical approach, radiotherapy and chemotherapy. The effects of these treatments are functional, aesthetic and psychological. The functions impacted are chewing, phonation, ventilation and swallowing.

Few data are available on quality of life of these patients and its association with some of their socio-demographic, medical and clinical characteristics (drug use, type of maxillo-mandibular loss of substance, disorder(s) associated with substance loss, ...).
