title: Transoral approach using the mandibular osteotomy for atlantoaxial vertical subluxation in juvenile rheumatoid arthritis associated with mandibular micrognathia.
abstract: We report a case of atlantoaxial vertical subluxation with mandibular micrognathia associated with juvenile rheumatoid arthritis. The patient was treated by odontoidectomy via the transoral approach and required a sagittal split mandibular osteotomy because of the mandibular micrognathia. The clinical outcome was excellent.
