研究目的: |
主要目的:定量评估 HFA 患者接受首次软组织增量手术后(自体脂肪移植或 ALT 游离皮瓣)在术后 ≥6 个月的面部对称性改善幅度。 次要目的:1) 在具备 3D 扫描数据的亚组中,评估体积缺损、对称性指标(AI、AR)及三轴改善(Cx/Cy/Cz),并描述纠正效应的空间异质性。2) 探索影响对称性改善幅度的独立预测因子(重点:手术方式;并纳入 BMI、严重程度、术时疾病进展状态等)。 |
||||||||||||||||||||||
|
Objectives of Study: |
Primary objective: To quantitatively assess the magnitude of facial symmetry improvement in patients with HFA at ≥6 months after their first soft-tissue augmentation surgery (autologous fat grafting or an anterolateral thigh [ALT] free flap). Secondary objectives: (1) In the subgroup with available 3D scan data, to evaluate volume deficiency, symmetry indices (AI and AR), and three-axis improvements (Cx/Cy/Cz), and to characterize the spatial heterogeneity of the corrective effect. (2) To identify independent predictors of the magnitude of symmetry improvement, with a primary focus on surgical modality, while adjusting for BMI, disease severity, and disease progression status at the time of surgery. |

Inclusion criteria |
1.Patients with a clinical diagnosis of HFA; 2. Underwent their first soft-tissue augmentation surgery (fat grafting or an anterolateral thigh [ALT] free flap) between 2020 and 2023; 3. Standardized 2D photographs available at baseline (preoperatively) and at the first postoperative follow-up (>6 months); 4. A subset of patients had pre- and/or postoperative 3D scan data. |
||||||||||||||||||||||
|
排除标准: |
1.既往接受过面部软组织增量手术; 2.首次手术同期实施除脂肪移植或游离皮瓣重建以外的其他面部手术; 3.病历资料不完整或随访不足(<6个月); 4.在用于结局评估的随访时间点之前接受额外增量或修复手术者。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Prior facial soft-tissue augmentation surgery; 2. Concomitant facial procedures at the index operation other than fat grafting or free-flapreconstruction; 3. Incomplete medical records or insufficient follow-up (<6 months); 4. Receipt of additional augmentation or revision surgery before the follow-up time point used for outcome assessment. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
CRF:研究团队制定标准化病例记录表(CRF)与数据字典,涵盖人口学信息、疾病特征、手术方式、随访时间点及结局指标;采用“双人独立提取+交叉核对”,保留疑问表(query)与修改审计记录。 EDC:采用 ResMan 互联网电子数据采集与管理系统进行数据录入、逻辑校验、疑问管理与版本控制;数据以研究编号去标识化存储,分级授权访问并定期备份。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
CRF: A standardized CRF and data dictionary will be developed, covering demographics, disease characteristics, surgical modality, follow-up time points, and outcomes. Data will be extracted independently by two investigators with cross-checking; queries and an audit trail will be maintained. EDC: ResMan will be used as the web-based EDC for data entry, logic checks, query management, version control, role-based access, and regular backups, with de-identified study IDs. |
