Abstract
The authors report a cystic lesion within a previous unilateral cleft lip and alveolus bone graft site in a 15-year-old girl, 5 years after the secondary bone graft. The cyst comprised respiratory epithelial lining, which is thought to be a remnant of the nasal mucosal lining of the primary cleft.
