The imagenologic exam evidenced radiolucent image, delimited, with involved unerupted tooth located in the mandibular rami area. The removal of the tooth was made under general anesthesia and submandibular extraoral access. The microscopic analysis revealed fragments of fibrous conjunctive tissue of capsular conformation with hemorrhage and chronic intense infiltrated inflammatory nonspecific and focuses widespread areas, besides epithelium odontogenic covering the conjunctive surface, compatible characteristics with cyst dentigerous infected.

Conclusion: The position of the tooth and the presence and extension of the lesion were decisive in the choice of the extraoral access, that it allowed good visualization of the surgical place and effectiveness enucleation of the cystic lesion.
