Orthognathic surgery is a recognised way of correcting dentofacial deformities and it is common practice to treat problems that affect the chin simultaneously, while deferring or not treating nasal deformities. There is inadequate published information about the prevalence of nasal deformities in such patients, and our aim was to remedy this. We retrospectively studied 75 patients with dentofacial deformities to find out if there was an association between nasal and dentofacial abnormalities. Forty-six of the 75 patients (61%) had mild to prominent cosmetic nasal problems, of whom 27 had deformities of the nasal bridge, 22 of the lobule of the nasal tip, 20 of nasal width, 14 in the width of the alar base, and 11 of the columella; 8 presented with deviation of the nose, and 6 with abnormal nasal length. Skeletal classes II and III had only slightly varied emphasis on nasal deformities. In comparison 14 patients (19%) had problems with the chin that required, or had already had, genioplasty. We also studied 9 patients who had had corrective bimaxillary surgery with simultaneous rhinoplasty. We set no formal questionnaire, but all patients expressed satisfaction with the postoperative results.
正颌外科手术是矫正牙颌面畸形的一种公认方法，同时治疗影响下巴的问题而推迟或不治疗鼻畸形是常见的做法。关于此类患者鼻畸形患病率的公开信息不足，我们的目的是弥补这一不足。我们回顾性研究了75例牙颌面畸形患者，以确定鼻畸形与牙颌面异常之间是否存在关联。75例患者中有46例（61%）存在轻度至明显的鼻美容问题，其中27例有鼻梁畸形，22例有鼻尖小叶畸形，20例有鼻宽畸形，14例有鼻翼基底宽度畸形，11例有鼻小柱畸形；8例有鼻偏斜，6例有鼻长度异常。骨骼II类和III类对鼻畸形的关注仅略有不同。相比之下，14例患者（19%）有下巴问题，需要或已经接受了颏成形术。我们还研究了9例接受双颌矫正手术同时进行鼻整形术的患者。我们没有设置正式问卷，但所有患者对术后结果都表示满意。
