摘要

在美容领域,颌下肌是常用的肉毒杆菌神经毒素面部塑形靶肌肉。然而,似是而非的颌下肌隆起是一种常见的不良反应,尚未通过超声波观察加以讨论。2021 年 10 月至 2023 年 1 月期间进行了一项回顾性研究,在 324 名患者中,每侧 25 单位(A 型莱妥霉素)的盲注肉毒杆菌神经毒素注射在颌下肌的中下部,有 3 名患者出现了矛盾性颌下肌隆起,医生通过超声波检查观察到了这一图像。根据观察结果,我们可以推断,活动肌的功能包括收缩时肌纤维的扭转,以及深下肌腱的扭转,这导致肌肉分为前区和后区,而不是颌间肌的浅区和深区。通过超声波观察矛盾性颌间肌隆起患者的皮肤表面,可以观察到前部或后部明显收缩。前后室的功能单元可观察到前部或后部功能单元的肌肉收缩向内运动。

Sonographic observation of the paradoxical masseteric bulging and clinical implication of functional compartment.

Masseter are commonly botulinum neurotoxin targeted muscle for facial contouring in aesthetic field. However, paradoxical masseteric bulging is common adverse effect that has not been discussed with ultrasonographic observations. Retrospective study has been conducted from October, 2021 to January, 2023, out of 324 patients have done blinded botulinum neurotoxin injection in the masseter at the middle and lower portion of the masseter with each side of 25 units (letibotulinum neurotoxin type A), 3 patients demonstrated paradoxical masseteric bulging has been reported and the image observed by ultrasonography by physician. Based on the observations made, we can infer that the function of the moving muscle involves twisting of the muscle fibers during contraction, along with the twisting of the deep inferior tendon, which causes the muscle to be divided into anterior and posterior compartments rather than into superficial and deep compartments of masseter. In ultrasonographic observe the skin surface of a patient with paradoxical masseteric bulging, it is observable that either the anterior or posterior part contracts significantly. The functional units of anterior and posterior compartment are observable as muscular contraction of inward movement of the muscle from either the anterior or posterior functional unit.
