Hypertrophy of the gastrocnemius muscle is considered to be a hindrance to lower leg beauty in the Asian aesthetic market. A noninvasive technique that has been gaining recognition involves botulinum toxin A injection; however, there are no proper guidelines or standardized protocols for the administration of botulinum toxin to correct gastrocnemius hypertrophy.
This study sought to determine the most effective botulinum toxin injection method for correcting the contour of the lower leg calf, as well as to determine the dose that can produce the maximum effect in meeting the demands of the physician and patient.
Eighteen female patients aged between 18 and 35 years were enrolled in this study from January 2015 to July 2015. Two injection methods were compared: (I) 48 injection points with a distance of 2 cm between every point; and (II) 10 injection points. Magnetic resonance imaging examinations were conducted at baseline prior to treatment and at one month and 6 months after treatment. A 3-dimensional study was performed to analyze the volumetric changes.
The most effective and significant treatment method for hypertrophic gastrocnemius muscle was the 48-point method (scattering injection). Following injection, this method exhibited a significant level of satisfaction with outcome.
Our study reveals that injection dosage and method have a strong relationship with achieving a better contouring result.
在亚洲审美市场中，腓肠肌肥大被认为是影响小腿美观的因素。一种逐渐获得认可的非侵入性技术是注射A型肉毒毒素；然而，对于使用肉毒毒素矫正腓肠肌肥大，尚无适当的指南或标准化方案。
本研究旨在确定矫正小腿轮廓最有效的肉毒毒素注射方法，并确定能在满足医生和患者需求方面产生最大效果的剂量。
2015年1月至2015年7月，18名年龄在18至35岁之间的女性患者纳入本研究。比较两种注射方法：（I）48个注射点，各点间距2厘米；（II）10个注射点。在治疗前基线、治疗后1个月和6个月进行磁共振成像检查。进行三维研究以分析体积变化。
对于肥厚性腓肠肌，最有效且显著的治疗方法是48点法（分散注射）。注射后，该方法对结果的满意度较高。
我们的研究表明，注射剂量和方法与获得更好的塑形效果密切相关。
