Améloblastome du sinus maxillaire traité par radiothérapie.

Ameloblastoma is a benign aggressive odontogenic tumor which requires early diagnosis and appropriate treatment. It commonly affects the mandible and radical surgery is the gold standard treatment. We report the case of a patient with ameloblastoma in extremely advanced phase affecting the maxillary sinus who was treated with intensity modulated conformal radiation therapy. Patient's evolution was marked by complete remission maintained after 24 months follow-up. Maxillary ameloblastoma is not well documented in the literature. It is usually diagnosed at the later stage when optimal surgery cannot be performed. This case study aimed to demonstrate that radiation therapy is a real therapeutic alternative in the treatment of advanced and inoperable forms of ameloblastoma. [ABSTRACT FROM AUTHOR]
