Objective To measure and analyze the external nasal morphology of normal Uygur in Xinjiang,which will provide the anatomical basis for the rhinoplasty.Methods From the Department of Otolaryngology and Plastic Surgery of our hospital,we collected the Uighur patients' families as the research objects during January 2011 to December 2012,and at the same time Han nationality patients' families were set as control group.Related parameters of external nose measurements were completed,and the parameters of external nose of 95％ confidence interval calculated,and compared with those of Han people.Results The measured data showed that there were the 95％ confidence interval of the Uighurs external nasal related indicators; The nasal length,height,depth,dorsum slope length,temples,nasal tip angle of the male Uighur were greater than those of male Han; Uighur women had longer,higher nose,more slope length of the nose back,and greater nasal-facial angle and nosewing angle than that of Han women.The proportion of ultra narrow nasal type,narrow nose,the middle nose in Uighur men was 14.02％,79.50％,and 6.48％ ; that in Uighur women was 14.60％,67.72％,and 17.68％,respectively; compared with those in Han nationality,there was a significantly statistical difference (P＜0.05).Conclusions The external nasal morphology of the Uygur people in Xinjiang has its characteristics,with dominants of narrow nasal type; 95％ of medical reference range will provide an objective reference basis for the future clinical work.
