Abstract

Background: Autologous fat grafting (AFG) is widely used to treat progressive hemifacial atrophy (PHA), but accurate measurement of tissue defects in PHA patients remains a challenge due to varied facial defects and complex anatomy.

Methods: This retrospective study monitored patients undergoing AFG over 12-16 months. Using 3D computed tomography (CT), the midsagittal plane of the face was scanned, mirror-image analysis (MIA) was carried out, and soft tissue volume loss was predicted across facial regions. The patients were evaluated at four intervals (preoperatively and at 3, 6, and 12 months postoperatively) by calculating the asymmetry index (AI), asymmetry rate (AR), preoperative soft tissue volume deficiency (Preop STVD), volume deficiency rate (VDR), and percentage volume maintenance (PVM). Patient characteristics, satisfaction, and outcomes were also analyzed.

Results: Fifteen patients (mean age 22) underwent an average of 1.9 AFG surgeries. Preoperative soft tissue defect volume was measured at 101.96 ± 82.52 cm³, with an average fat injection volume of 93.38 ± 73.71 cm³. Tissue defect rates ranged from 1.43 to 10.16% (mean 4.42 ± 3.47%), and volume maintenance varied from 35.60 to 79.16% (average 56.64 ± 13.48%). Postoperatively, defect rates ranged from 0.78 to 4.86% (mean 2.11 ± 1.66%), with volume maintenance between 52.36 and 71.74% (average 63.50 ± 8.09%). Significant improvements in facial symmetry and patient satisfaction were noted, with no complications reported.

Conclusion: Digitally guided precision fat grafting is a promising method for predicting soft tissue loss and improving facial symmetry in patients with progressive hemifacial atrophy.

Level of evidence iv: This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .

数字引导精确脂肪移植治疗进行性面瘫。

背景：自体脂肪移植（AFG）被广泛用于治疗进行性面瘫（PHA），但由于面部缺陷的多样性和复杂的解剖结构，准确测量PHA患者的组织缺陷仍然是一个挑战。方法：回顾性研究监测AFG患者12-16个月。使用三维计算机断层扫描（CT）扫描面部正中矢状面，进行镜像分析（MIA），并预测面部各区域的软组织体积损失。通过计算不对称指数（AI）、不对称率（AR）、术前软组织体积缺乏率（Preop STVD）、体积缺乏率（VDR）和体积维持百分比（PVM），对患者进行术前、术后3个月、6个月和12个月的评估。还分析了患者的特征、满意度和结果。结果：15例患者（平均年龄22岁）平均接受1.9次AFG手术。术前测量软组织缺损体积101.96±82.52 cm3，平均脂肪注射体积93.38±73.71 cm3。组织缺损率为1.43 ~ 10.16%（平均4.42±3.47%），体积维持率为35.60 ~ 79.16%（平均56.64±13.48%）。术后缺损率为0.78 ~ 4.86%（平均2.11±1.66%），体积维持率为52.36 ~ 71.74%（平均63.50±8.09%）。面部对称性和患者满意度显著改善，无并发症报道。结论：数字引导下的精确脂肪移植是预测进行性面瘫患者软组织缺损和改善面部对称性的一种很有前途的方法。证据等级iv：本刊要求作者为每篇文章指定一个证据等级。有关这些循证医学评级的完整描述，请参阅目录或在线作者说明www.springer.com/00266。

期刊介绍： Aesthetic Plastic Surgery is a publication of the International Society of Aesthetic Plastic Surgery and the official journal of the European Association of Societies of Aesthetic Plastic Surgery (EASAPS), Società Italiana di Chirurgia Plastica Ricostruttiva ed Estetica (SICPRE), Vereinigung der Deutschen Aesthetisch Plastischen Chirurgen (VDAPC), the Romanian Aesthetic Surgery Society (RASS), Asociación Española de Cirugía Estética Plástica (AECEP), La Sociedad Argentina de Cirugía Plástica, Estética y Reparadora (SACPER), the Rhinoplasty Society of Europe (RSE), the Iranian Society of Plastic and Aesthetic Surgeons (ISPAS), the Singapore Association of Plastic Surgeons (SAPS), the Australasian Society of Aesthetic Plastic Surgeons (ASAPS), the Egyptian Society of Plastic and Reconstructive Surgeons (ESPRS), and the Sociedad Chilena de Cirugía Plástica, Reconstructiva y Estética (SCCP). Aesthetic Plastic Surgery provides a forum for original articles advancing the art of aesthetic plastic surgery. Many describe surgical craftsmanship; others deal with complications in surgical procedures and methods by which to treat or avoid them. Coverage includes "second thoughts" on established techniques, which might be abandoned, modified, or improved. Also included are case histories; improvements in surgical instruments, pharmaceuticals, and operating room equipment; and discussions of problems such as the role of psychosocial factors in the doctor-patient and the patient-public interrelationships. Aesthetic Plastic Surgery is covered in Current Contents/Clinical Medicine, SciSearch, Research Alert, Index Medicus-Medline, and Excerpta Medica/Embase.
