Abstract:
OBJECTIVETo establish the quantitative diagnostic criteria for cranio-orbito-zygomatic deformity (COZD).
METHODSComputer-assisted three-dimensional (3-D) CT measurement was performed in 30 cases with unilateral COZD. The differences of the measurement data between the affected and unaffected sides were analyzed. Then the patients were diagnosed and classified according to the affected bone, soft tissue and conjunctival sac. Based on the quantitative diagnosis, 8 patients underwent surgery to test the clinical practicability of the diagnostic criteria.
RESULTSThe quantitative diagnostic criteria for COZD could reflect the affected area and the corresponding severity of deformity. It helped to preoperative design and to predict movement of osteotomy segment and. the soft tissue volume needed for augmentation. Good postoperative results were achieved.
CONCLUSIONSThe quantitative diagnostic criteria for COZD can describe the affect area and severity of deformity in detail. It is very practical in the guidance of clinical treatment.
