Atypical cyst formation following chin augmentation using a nasal osteocartilaginous graft.

The purpose of this paper is to present a case of an intraosseous mucocele that was detected 5 years after chin augmentation using a nasal osteocartilaginous graft. Although complications of this technique have been described as negligible, the surgeon must be aware of possible long-term side effects and should remove all nasal mucosa from the graft prior to implantation.
