The aim of this study was to evaluate the effect of different nose types on the perception of facial aesthetics following camouflage treatment and orthognathic surgery for skeletal class II female patients. A pre-treatment profile photograph of a skeletal class II adult patient was selected from the department archive. Two constructed photographs were created to represent orthognathic surgery and camouflage treatments with the aid of computer software. A total of 18 constructed images was composed using three profiles (pre-treatment, post-camouflage, and post-orthognathic surgery) and six nose types. These photographs were shown to the three groups (orthodontists, plastic surgeons, and lay people), and they were asked to assign an attractiveness score to each photo ranging from 0 to 100, with 0 indicating the least attractive and 100 indicating the most attractive. For the convex nose profiles, anterior movement of the mandible obtained by orthognathic surgery did not result in a significant change in the scores given by the lay people. When surgical or camouflage treatment was not implemented and, instead, just rhinoplasty was performed for these profiles, there was a significant increase in the aesthetic scores given by all groups. For the straight nose profiles, orthognathic surgery increased the attractiveness scores given by all groups. Furthermore, for all the profiles, extraction treatment did not affect the aesthetic scores given by any of the groups (P > 0.05). The lay people perceived that having a convex-bridged nose was a bigger problem than having a retrognathic profile. Overall, in terms of skeletal and dental orthodontic treatments, nose shape should be considered during the treatment planning process.

不同鼻子类型对女性患者II类治疗的影响。

这项研究的目的是评估骨骼II类女性患者伪装治疗和正颌外科手术后不同鼻子类型对面部美感的影响。从部门档案中选择了骨骼II级成年患者的治疗前概况照片。借助计算机软件，制作了两张构造好的照片来代表正颌外科手术和伪装治疗。使用三种配置文件（预处理，伪装后和正颌手术后）和六种鼻子类型构成了总共18张构造的图像。这些照片分别显示给三组（正畸医生，整形外科医生和外行人），并要求他们为每张照片分配一个吸引力分数，范围从0到100，其中0表示吸引力最低，而100表示​​吸引力最高。对于凸出的鼻子轮廓，通过正颌外科手术获得的下颌骨的前移并未导致外行人得分的显着变化。如果不进行外科手术或伪装治疗，而仅对这些轮廓进行隆鼻术，则所有组的美学评分均显着提高。对于笔直的鼻子轮廓，正颌外科手术增加了所有组的吸引力得分。此外，对于所有配置文件，提取处理均不影响任何组的美学评分（P> 0.05）。外行人认为鼻梁隆起比逆行牙型是一个更大的问题。总体，
