Resection of the depressor septi in rhinoplasty has been used to correct the smiling deformity. Studying the effects of this maneuver on the upper lip length is important for operative planning, as well as for patient counseling.
To define an approach to the resection of the depressor septi muscle during functional and aesthetic rhinoplasty and to determine whether performing this maneuver causes any measureable change in the length of the upper lip in the repose position.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective medical record review and photographic analysis were performed on 36 patients who had undergone rhinoplasty involving resection of the depressor septi by either of 2 of the investigators at a tertiary care academic center and a private practice between 2010 and 2013. All maneuvers performed during the procedure were recorded. Preoperative photographs were compared with postoperative photographs using Adobe Photoshop, and percent change in upper lip length was calculated.
Rhinoplasty involving resection of the depressor septi.
Percent change in upper lip length, calculated by measuring the ratio between upper lip length and intercanthal distance and comparing the preoperative and postoperative ratios.
Thirty-six patients were evaluated, including 22 men and 14 women. Postoperative photographs were taken a mean (range) of 7.06 months (7 days to 2 years) after surgery. The mean change was a 1.74% decrease in upper lip length; 24 patients (67%) had a decrease (mean [maximum], 5.89% [21.22%]), and 12 patients (33%), an increase (mean [maximum], 6.55% [12.68%]) in upper lip length. Compared with the preoperative lip length, the mean (95% CI) postoperative lip length was 100.09% (97.35%-102.83%) in women vs 95.37% (90.86%-99.88%) in men (P = .07). No predictable factors determined whether a patient would develop a postoperative increase or decrease in upper lip length.
Resection of the depressor septi muscle during rhinoplasty is a well-documented maneuver often used in the treatment of the ptotic tip and smile deformity. This descriptive study showed that resection of the depressor septi muscle has an unpredictable but small effect on upper lip length in the repose position.
鼻整形术中切除降鼻中隔肌已被用于矫正微笑畸形。研究此操作对上唇长度的影响对于手术规划以及患者咨询都很重要。
确定在功能性和美容性鼻整形术中切除降鼻中隔肌的方法，并确定进行此操作是否会导致静息位时上唇长度发生任何可测量的变化。
设计、地点和参与者：对2010年至2013年期间在一家三级医疗学术中心和一家私人诊所由两名研究者之一进行的涉及切除降鼻中隔肌的36例鼻整形术患者进行了回顾性病历审查和照片分析。记录手术过程中进行的所有操作。使用Adobe Photoshop将术前照片与术后照片进行比较，并计算上唇长度的百分比变化。
涉及切除降鼻中隔肌的鼻整形术。
通过测量上唇长度与内眦间距的比值并比较术前和术后的比值来计算上唇长度的百分比变化。
共评估了36例患者，其中男性22例，女性14例。术后照片在术后平均（范围）7.06个月（7天至2年）拍摄。平均变化是上唇长度减少1.74%；24例患者（67%）上唇长度减少（平均[最大值]，5.89%[21.22%]），12例患者（33%）上唇长度增加（平均[最大值]，6.55%[12.68%]）。与术前唇长相比，女性术后唇长平均（95%CI）为100.09%（97.35%-102.83%），男性为95.37%（90.86%-99.88%）（P = 0.07）。没有可预测的因素能确定患者术后上唇长度是增加还是减少。
鼻整形术中切除降鼻中隔肌是一种有充分文献记载的操作，常用于治疗鼻尖下垂和微笑畸形。这项描述性研究表明，切除降鼻中隔肌对静息位时上唇长度有不可预测但很小的影响。
