M. Yamaoka et al., THE ASSESSMENT OF FRACTURE OF THE MANDIBULAR CONDYLE BY USE OF COMPUTERIZED-TOMOGRAPHY - INCIDENCE OF SAGITTAL SPLIT FRACTURE, British journal of oral & maxillofacial surgery, 32(2), 1994, pp. 77-79
A survey was carried out to clarify the incidence of sagittal splittin
g fracture of the mandibular condyle using computerized tomography. Th
ere were 33 patients, between 11 and 67 years of age, with displaced o
r dislocated mandibular condylar process fractures (41 cases), seen at
our clinic between 1986 and 1992. The incidence of no displacement wa
s 4.9%; deviation and displacement, 34.1%; dislocation, 46.3%; and com
plete avulsion, 4.9%. A sagittal splitting fracture of condyle occurre
d with an incidence of 9.8%. Conservative treatment was effective in t
he treatment of sagittal splitting fracture. Therefore, classification
of fracture of mandibular condyle should include the sagittal split f
racture, and investigations should include computerized tomography.
