Abstract

Adenomatoid odontogenic tumor (AOT) is a benign, slow-growing lesion and it is considered the fourth most common odontogenic tumor. AOT affects more frequently the young subjects with a predilection for the second and third decades of life. We present here the case of a 36-year-old man affected by large extrafollicular AOT which caused roots resorption of multiple teeth. The lesion involved the entire right maxillary bone and extended into the right maxillary sinus up to the orbital floor and the nasal cavity. Intra-oral surgical excision of the AOT and functional endoscopic sinus surgery led to complete clinical healing in absence of local recurrences.

Key words: Adenomatoid odontogenic tumor / odontogenic cysts / oral surgery
