Examining the upper lip position is a key indicator of facial beauty. This study aimed to examine the upper lip position following cosmetic rhinoplasty at the frontal and profile views. The medical records of 67 patients who underwent rhinoplasty with no history of any facial skeletal surgery were obtained from archives. Complete preoperative and postoperative photos including the profile view at rest and the frontal view at rest, were prepared and analysed using Adobe Photoshop CC 2015 software. Interpupillary distances of two eyes in frontal views and Glabella to Pogonion (POG) distance in profile views were considered as fixed landmarks to calibrate the preoperative and postoperative photos. Upper lip length, subnasal area, and vermilion points were marked and compared between preoperative and postoperative photos. Data analysis was carried out using one-sample t-test and p<0.05% was considered as the significant level. Lip length (frontal view) was increased in 46 subjects. There were changes in the profile view of vermilion and subnasal positions in 56 patients and 53 patients, respectively. In surgical procedures on columella strut, maxillary augment, alar resection, spreader graft, columella retraction, and depressor septi muscle release, vermilion and subnasal protrusion in the profile view was statistically significant and lip length increased significantly in the frontal view. In tip rotation surgery techniques, the vermilion and subnasal position showed also significant protrusion. The depressor septi muscle cutting methods had only led to a significant protrusion of the vermilion position and upper lip length. Despite all covariants interfering in rhinoplasty, this cosmetic surgery most often may increases maxillary lip length and helps that maxilla look more protruded.
检查上唇位置是衡量面部美观的关键指标。本研究旨在从正面和侧面观察美容鼻整形术后的上唇位置。从档案中获取了 67 名接受过鼻整形术且无任何面部骨骼手术史的患者的病历。准备并使用 Adobe Photoshop CC 2015 软件分析了包括术前和术后的正面休息和侧面休息在内的完整术前和术后照片。正面视图中两个眼睛的瞳孔距离和侧面视图中的 Glabella 到 Pogonion（POG）距离被认为是固定的地标，用于校准术前和术后的照片。在术前和术后照片上标记上唇长度、鼻下区域和唇红区域，并进行比较。使用单样本 t 检验进行数据分析，p<0.05% 被认为具有统计学意义。在 46 名受试者中，唇长（正面视图）增加。在 56 名患者和 53 名患者中，分别有 56 名和 53 名患者的唇红和鼻下位置在侧面视图中发生了变化。在鼻中隔支柱手术、上颌骨增大、鼻翼切除、撑开移植物、鼻中隔退缩和鼻中隔降肌松解术中，侧面视图中的唇红和鼻下突出具有统计学意义，正面视图中的唇长显著增加。在鼻尖旋转手术技术中，唇红和鼻下位置也显示出明显的突出。鼻中隔降肌切割方法仅导致唇红位置和上唇长度显著突出。尽管所有协变量都干扰了鼻整形术，但这种美容手术通常可以增加上颌唇长度，使上颌看起来更加突出。
