Background

Botulinum toxin type A has been used for treating the hypertrophy of the masseter muscles and its cosmetic effects. Ultrasound is increasingly used in dermatology, along with the guidance of mini-invasive procedures.

 

Aims

To evaluate the role of ultrasound for guiding the application of Botulinum A toxin in patients with cosmetic alterations due to bruxism, correlate the clinical landmarks with the ultrasound findings, and study the effect on the symptoms, cosmetics, and quality of life.

 

Patients/Methods

Twenty individuals with bruxism and cosmetic alterations underwent an ultrasound-guided injection of Botulinum toxin type A in each masseter muscle. Clinical and ultrasound marking of the procedure was compared. Clinical and sonographic evaluation was performed at the time of injection and 3 months later. Ten normal individuals underwent ultrasound of the masseter muscles as a control group.

 

Results

Up to 65% of individuals showed anatomical variants of the salivary glands. The method for clinically marking the skin showed a frequently erroneous location of the anterior point (up to 40% of cases) that was proven by ultrasound to be out of the muscle. In 20% of cases, ultrasound showed that the needle should be longer to enter the muscle. After injection, most of the patients demonstrated a decrease of the symptoms and cosmetic and quality of life improvements.

 

Conclusions

Ultrasound can be a potent tool for guiding the injection of Botulinum toxin into the masseter muscles. It may contribute to a more personalized procedure, better cosmetic results, and help to avoid potential complications.

背景

A型肉毒毒素已用于治疗咬肌肥大及其美容效果。随着微创手术的指导,超声在皮肤科的应用越来越多。

 

目的

评价超声对磨牙症美容改变患者应用A型肉毒毒素的指导作用,并将临床标志与超声检查结果进行对照,研究其对患者症状、美容效果及生活质量的影响。

 

患者/方法

20例磨牙症和美容改变的患者在超声引导下分别在每块咬肌内注射A型肉毒毒素。将临床标记与超声标记进行比较。分别在注射时和注射后3个月进行临床和超声检查。10例正常人作为对照组,进行咬肌超声检查。

 

结果

高达65%的个体表现出唾液腺的解剖变异。临床标记皮肤的方法经常显示前点的错误位置(高达40%的病例),超声证实它在肌肉之外。在20%的病例中,超声波显示针进入肌肉的时间应该更长。注射后多数患者症状减轻,美容改善,生活质量提高。

 

结论

超声可作为指导肉毒毒素注射到咬肌的有力工具。它可能有助于更个性化的手术,更好的美容效果,并有助于避免潜在的并发症。
