At present, nasal abnormalities is often classified from different perspectives, such as the alar-columella relationship, nasal base width, and the condition of alar hyperplasia. However, due to the impact of race and region, different people may be applied to different classification methods, resulting in different clinical diagnosis and treatments. So far, there is no unified standard for alar deformity classification to guide clinical treatment. In alar-columella relationship, the retracted ala and the hanging columella, hanging ala and retracted columella are easily confused. According to the classification of nasal base width, it is easy to confuse the alar flare with wide alar base. Therefore, the accurate preoperative evaluation of the nasal ala and the selection of appropriate clinical treatments for different abnormalities are beneficial for surgeons to achieve perfect rhinoplasty results.
目前常从鼻翼鼻小柱比例关系、鼻基底宽度、鼻翼肥大等不同角度对鼻翼畸形进行分型，但由于人种、地域等因素的影响，不同的人群可能适用于不同的分型方式，从而出现不同的临床诊断及治疗方式，目前仍未能形成一个统一的鼻翼畸形分型的标准。在鼻翼鼻小柱比例关系中，鼻翼退缩与鼻小柱悬垂、鼻翼悬垂与鼻小柱退缩容易混淆；在鼻基底宽度分型中，鼻翼基底过大与鼻翼外扩侧凸容易混淆。所以术前对鼻翼进行准确的评估，针对不同畸形选择合适的临床治疗方法，有利于外科医生达到完美的鼻整形效果。.
