背景:长毛囊单位切除(LHF)越来越受欢迎,特别是对于发际线的恢复,因为它有助于避免在供体区域脱毛,并提供更好的术后即时结果。
目的:本研究旨在评估LHF用于发际线修复的术后临床结果。
方法:分析了2018年9月至2022年6月接受LHF发际线恢复的248例患者(223名女性和25名男性)的数据,术后立即随访9个月。评估长毛移植物的并发症和生存率。使用5点Likert量表评估患者术后满意度。通用生活质量量表-74(GQOLI-74)评估了术后生活质量。
结果:计划提取密度设定为15-25FU/cm2。提取的毛发移植物总数的平均数,提取区的横切率,提取时间为1970±124FU,3.9±0.2%,和3.2±0.8小时,分别。将发丝植入密度设定为50-70FU/cm2。平均植发总数为2031±371FU;植入时间为3.8±1.9h。术后7天内无严重并发症发生。术后9个月平均移植物存活率为93.1±1.3%。所有患者均对术后即刻效果满意,大多数患者对9个月结局感到满意(平均总满意度得分为4.7分).身体机能的分数,心理功能,术后社会功能和物质生活功能均高于术前(p<0.0001)。
结论:Hairline修复LHF可以提高美容效果,并在临床实践中广泛使用。
BACKGROUND: Long-hair follicular unit excision (LHF) is gaining popularity, especially for hairline restoration, because it helps avoid hair removal in the donor area and provides better immediate postoperative results.
OBJECTIVE: This study aimed to assess the postoperative clinical outcomes of LHF for hairline restoration.
METHODS: Data from 248 patients (223 women and 25 men) who underwent hairline restoration with LHF between September 2018 and June 2022 were analyzed, and they were followed up immediately and 9 months postoperatively. The complications and survival rate of long-hair grafts were assessed. Patient postoperative satisfaction was assessed using a 5-Point Likert Scale. The Generic Quality of Life Inventory-74 (GQOLI-74) assessed the quality of the postoperative life.
RESULTS: The planned extraction density was set at 15-25 FU/cm2. The mean number of total extracted hair grafts, transection rate in the extraction area, and extraction time were 1970 ± 124 FU, 3.9 ± 0.2%, and 3.2 ± 0.8 h, respectively. The hairline implantation density was set at 50-70 FU/cm2. The mean number of total transplanted hair grafts was 2031 ± 371 FU; the implant time was 3.8 ± 1.9 h. No serious complications occurred within 7 days postoperatively. The mean graft survival rate was 93.1 ± 1.3% at 9 months postoperatively. All patients were satisfied with the immediate postoperative results, and most were satisfied with the 9-month outcomes (mean overall satisfaction score: 4.7). The scores of physical function, psychological function, social function and material life function after operation were higher than those before operation (p < 0.0001).
CONCLUSIONS: Hairline restoration with LHF could enhance the cosmetic outcomes and be widely used in clinical practice.
