Objective: the human body is the harmonization of the whole must be some kind of regular contact between the craniofacial skeleton. Mandible, the ratio between the zygomatic arch opposite plays a decisive role, this paper aims through the normal population of a certain number of the mandible and the zygomatic arch measurement, both the correlation analysis, in vivo through direct and simple The measuring mandibular angle width to calculate the depth of the zygomatic arch, length, thickness and mandible indicators. For the study of the the the deeper intrinsic relationship between the head facial bones provide evidence of relevant reference materials for aesthetic medicine and other medical fields. In many disciplines of science, forensic science and artificial implant production of plastic surgery has important clinical significance. : Select age in healthy men and women 20-30 years old 19 each, a total of 38 people, its handsome, no facial soft tissue and skeletal abnormalities, no history of Orthodontics. Spiral CT scan, select the thickness of 2.5mm, in the downstream head the normal cusp staggered bit status spiral CT scan. Information input data obtained from CT workstations, workstation three-dimensional reconstruction of the skull measured after the reconstruction of the mandible and zygomatic arch indicators, the measured data were analyzed using statistical software SPSS11.0. Results: 19 male subjects between the mandibular angle width: 101.39 ± 4.98mm, the mandibular condyle width: 130.51 ± 6.63mm, mandibular symphysis depth: 75.36 ± 4.75mm, mandibular joint: 34.91 ± 3.28mm, high mandibular body: 33.43 ± 3.19mm, the mandibular body length: 35.11 ± 2.37mm, the ramus width: 62.04 ± 4.64mm, ramus: 77.97 ± 4.63mm, the zygomatic arch depth: 12.38 ± 1.35mm, zygomatic arch length: 39.48 ± 2.39mm, zygomatic arch thickness: 5.40 ± 0.48mm. 19 female subjects between the mandibular angle width: 91.19 ± 7.45mm, the mandibular condyle width: 124.00 ± 6.45mm, mandibular symphysis depth: 69.19 ± 4.70mm, mandibular joint: 31.99 ± 2.59mm, mandibular body: 30.96 ± 2.30 mm, mandibular body length: 33.78 ± 3.63 mm, ramus width: 57.58 ± 2.59mm, the ramus high: 71.83 4.70mm, zygomatic arch depth: 10.17 ± 1.40mm, zygomatic arch length: 36.64 ± 2.46mm the zygomatic arch Thick: 4.82 ± 0.78mm. Conclusion: The mandibular angle wide projections zygomatic arch depth, length, thickness and mandible their own indicators, mandible, zygomatic arch cosmetic surgery preoperative assessment and postoperative outcome prediction has certain reference value. The mandibular angle wide projections the zygomatic arch depth, length, thickness and mandible own indicators regression equation, the equation for Chinese people mandible and maxillofacial projections.
