The postoperative changes in the rotation of the nasal tip in rhinoplasty must be estimated for the surgical planning.
To determine whether the outcome in the rotation angle of the nasal tip can be estimated in patients undergoing primary rhinoplasty with the new domes technique.
DESIGN, SETTING, AND PARTICIPANTS: This retrospective analytic cohort study included 323 patients undergoing primary rhinoplasty with the new domes technique in a private clinic in Bogotá, Colombia, by a single surgeon from January 1, 2011, through January 31, 2016. Patients undergoing secondary rhinoplasty and those with less than 6 months of follow-up were excluded.
Primary rhinoplasty using the new domes technique.
Measurement of the rotation angle of the nasal tip before and 1 week and 6 months after surgery. The main variable taken into consideration was the measurement, in millimeters, of the lateralized nasal domes.
A total of 323 patients (288 women [89.2%] and 35 men [10.8%]; mean age, 27.8 years; age range, 13-70 years) were included in the study. The mean (SD) preoperative nasolabial angle was 92.7° (4.4°; range, 77°-107°); at 1 postoperative week, 105.5° (4.9°; range, 92°-120°); and at 6 postoperative months, 102.1° (4.6°; range, 90°-115°). The mean (SD) increase of the rotation that was achieved per lateralized millimeter was 3.6° (2.0°). The mean (SD) rotation angle at 6 months decreased to 3.4° (2.4°).
The new domes technique was reliable and reproducible in most patients. Despite the unpredictable inflammatory changes, the exact lateralization in millimeters with the new domes technique allowed precise estimation of the long-term outcome of the rotation of the nasal tip, enabling the surgeon to determine from the preoperative plan the definitive rotation angle of the nose.
在鼻整形术中，必须估计术后鼻尖旋转的变化，以便进行手术规划。
确定在接受新穹顶技术行初次鼻整形术的患者中，鼻尖旋转角度的结果是否可以预测。
设计、环境和参与者：这是一项回顾性分析队列研究，共纳入 2011 年 1 月 1 日至 2016 年 1 月 31 日期间在哥伦比亚波哥大的一家私人诊所接受新穹顶技术行初次鼻整形术的 323 例患者，由同一位医生进行手术。排除二次鼻整形术和随访时间少于 6 个月的患者。
使用新穹顶技术行初次鼻整形术。
术前、术后 1 周和 6 个月时鼻尖旋转角度的测量。主要考虑的变量是测量的侧向鼻中隔的毫米数。
共纳入 323 例患者（288 例女性[89.2%]和 35 例男性[10.8%]；平均年龄 27.8 岁；年龄范围 13-70 岁）。术前鼻唇角的平均（标准差）为 92.7°（4.4°；范围 77°-107°）；术后 1 周时为 105.5°（4.9°；范围 92°-120°）；术后 6 个月时为 102.1°（4.6°；范围 90°-115°）。每侧向毫米的旋转增加量的平均（标准差）为 3.6°（2.0°）。6 个月时的平均（标准差）旋转角度降至 3.4°（2.4°）。
在大多数患者中，新穹顶技术是可靠且可重复的。尽管存在不可预测的炎症变化，但新穹顶技术可以精确地以毫米为单位进行侧位定位，从而可以准确估计鼻尖旋转的长期结果，使外科医生能够根据术前计划确定鼻子的最终旋转角度。
