Objectives of Study:

1. Primary Objective:​​To compare the efficacy of fractional CO₂ laser application at 1 week versus 1 month postoperatively in preventing thyroidectomy scars, as assessed by the modified ​Scar ​Beauty ​Score ​Evaluation ​Scale (SBSES). ​2. Secondary Objectives:​​ To compare the efficacy of fractional CO₂ laser application at 1 week versus 1 month postoperatively in preventing thyroidectomy scars using secondary outcome measures: Visual ​Analog ​Scale (VAS); Observer ​Scar ​Assessment ​Scale (OSAS);Patient ​Scar ​Assessment ​Scale (PSAS);Mean scar measurement values. 3.To evaluate the safety of fractional CO₂ laser application at two distinct early postoperative time points—1 week (inflammatory phase) and 1 month (proliferative phase)—for preventing scar formation after thyroidectomy. 4.To elucidate the key mechanisms underlying fractional CO₂ laser therapy in preventing postoperative scar formation through histopathological analysis of tissue biopsies.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层区组随机化。分层因素包括年龄(<=40 岁/>40 岁)和性别(男/女)。使用 SPSS 26.0 软件生成随机序列,每层内设置区组长度 4,按 1:1比例分配至:1.试验组 :术后 1 周(4/10 天)接受 CO₂点阵激光治疗;2.对照组 :术后 1 月(4/10 天)接受 CO₂点阵激光治疗。随机分配方案密封于不透光编号信封中,信封标注分层编号及区组序号(如“层1-区组 1”),由不参与入组的研究助理保管。患者签署知情同意书且完成手术后,由指定护士在手术室现场拆封分组,即时记录分配结果,信封留存备查

Randomization Procedure (please state who generates the random number sequence and by what method):

Stratified block group randomisation was used in this study. Stratification factors included age (<=40 years/>40 years) and sex (male/female). A randomised sequence was generated using SPSS 26.0 software, with a block group length of 4 within each stratum, and allocated in a 1:1 ratio to: 1. Trial group : treated with CO₂ Fractional Laser at 1 week (4/10 days) postoperatively; 2. Control group : treated with CO₂ Fractional Laser at 1 month (4/10 days) postoperatively. The random allocation plan was sealed in an opaque numbered envelope labelled with the stratum number and zone number (e.g., "stratum 1 - zone 1"), which was kept by a research assistant who was not involved in the enrolment. After the patient has signed the informed consent form and completed the procedure, the designated nurse will unseal the group on site in the operating theatre and record the allocation result immediately, and the envelope will be kept for reference.
