背景：高强度聚焦超声（HIFU）已成为一种精确且无创的组织消融和愈合方式。本研究提供了高强度聚焦超声（HIFU）治疗后皮肤愈合的详细皮肤镜分析，关注常见的良性皮肤病变，比如脂溢性角化病,皮脂腺增生,血管病变,和皮脂腺痣.方法：在HIFU治疗之前，进行了全面评估，整合超声扫描和临床评估。TOOsonix系统ONE-M用于HIFU治疗，具有针对每种病变类型定制的参数。结果：在所有病变中观察到的常见模式包括治疗后的初始美白，随后是结痂形成和带有修复血管的粉红色区域的发展。这项研究,然而,强调不同病变类型的纤维化模式和愈合时间线的明显差异。每种病变类型在治疗后表现出独特的纤维化模式。脂溢性角化病的变种在一个月内愈合，显示色素沉着减退和修复血管，伴随着更多疣状形式的独特晶格纤维化模式，花了大约两个月的时间才痊愈.皮脂腺增生,以三周内快速愈合为特征，显示有粉红色区域和垂直白线的纤维化，最后是轻微的抑郁。血管病变的愈合时间因深度而异，浅层的皮肤显示出美白和结皮的形成，而较深的病变有血管闭塞和大小缩小，并伴有同心纤维化带。皮脂腺痣的最长愈合时间为三个月，以无定形白色灰色结构为特征，结痂形成,以及带有分支血管的粉红色区域的出现，导致皮肤清晰，白线减少。结论：总之，这项细致的临床评估突出了HIFU治疗每种类型皮肤病变的独特愈合特征和时间线.这些见解对于优化后续评估非常宝贵，识别潜在的并发症,和精炼处理方案。通过提供对不同类型病变的愈合时间表和模式的详细见解，患者可以更好地了解他们的治疗后旅程。
Background: High-Intensity Focused Ultrasound (HIFU) has emerged as a precise and non-invasive modality for tissue ablation and healing. This study presents a detailed dermoscopic analysis of skin healing post-High-Intensity Focused Ultrasound (HIFU) treatment, focusing on common benign skin lesions, such as seborrheic keratosis, sebaceous hyperplasia, vascular lesions, and sebaceous nevi. Methods: Prior to HIFU treatment, a comprehensive assessment was conducted, integrating ultrasound scanning and clinical evaluations. The TOOsonix System ONE-M was employed for HIFU treatments, with parameters tailored to each lesion type. Results: A common pattern observed across all lesions includes initial whitening post treatment, followed by scab formation and the development of a pink area with reparative vessels. This study, however, highlights distinct differences in fibrosis patterns and healing timelines across different lesion types. Each lesion type exhibited unique fibrosis patterns post treatment. Flatter variants of seborrheic keratosis healed within a month, displaying hypopigmentation and reparative vessels, alongside a distinct lattice fibrosis pattern in more verrucous forms, which took about two months to heal. Sebaceous hyperplasia, characterized by rapid healing within three weeks, demonstrated fibrosis with pink areas and perpendicular white lines, concluding with a slight depression. Vascular lesions varied in healing time based on depth, with superficial ones showing whitening and crust formation, while deeper lesions had vessel occlusion and size reduction accompanied by concentric fibrotic bands. Sebaceous nevi presented the longest healing duration of three months, characterized by amorphous white-gray structures, scab formation, and the emergence of pink areas with branching vessels, leading to clear skin with reduced white lines. Conclusions: in conclusion, this meticulous clinical evaluation highlights the unique healing characteristics and timelines for each skin lesion type treated with HIFU. These insights are invaluable for optimizing follow-up assessments, identifying potential complications, and refining treatment protocols. By providing detailed insights into the healing timelines and patterns for different types of lesions, patients can be better informed about their post-treatment journey.
