[Difference in lateral cephalogram of the male patients with Uygur and Han OSAHS]

Objective:To investigate the difference of lateral cephalogram, PSG, BMI in Uygur and Han OSAHS male patients. Method:OSAHS male patients with 33 Uygur cases and 42 Han cases,30 normal Uygur cases and 36 normal Han cases were taken as control.Lateral cephalogram of upright position in waking state, then comparecraniofacial strcture parameters and PSG dates, etc. Result:Patients in OSAHS group and normal group had significant differences in the MP-H, PAS, PNS-P, BMI (P<0.05), the Uygur healthy men and Uygur male OSAHS patients had significant difference in the ANB° (P<0.05). The difference was statistically significant in PNS-P, MP-H and BMI in Uygur and Han OSAHS male patients (P<0.05). Conclusion:The differences in airway plane, hyoid position and length of soft palate and weight were significantly different between healthy men and OSAHS men. Han OSAHS male patients and Uygur male patients had significant differences in Hyoid position, length of the soft palate and weight. Lateral cephalogram can judge blocking site of upper airway and provide opration plan.
