Botulinum toxin type-A (BTX-A) injections have emerged as a promising treatment for bruxism and temporomandibular joint (TMJ) disorders. However, there is a need for further exploration of optimal dosage, injection techniques, and intervals to maximize treatment effectiveness. Complications, such as velopharyngeal insufficiency, can occur after BTX-A injections, emphasizing the importance of precautionary measures. The utilization of ultrasound guidance and electromyography assistance can aid in precise injections and minimize the risk of complications. In addition, patients should receive appropriate medication and adhere to post-treatment instructions to alleviate symptoms. Follow-up procedures are essential to monitor potential complications, and in some cases, professional mental health care may be required. Further research is warranted to establish the safety and efficacy of BTX-A injections for the treatment of bruxism and TMJ disorders. This case study presents the development velopharyngeal insufficiency in a patient with chronic bruxism 3 days after receiving a BTX-A injection.
A型肉毒毒素（BTX-A）注射已成为磨牙症和颞下颌关节（TMJ）紊乱的一种有前途的治疗方法。然而，仍需要进一步探索最佳剂量、注射技术和间隔时间，以最大限度地提高治疗效果。BTX-A 注射后可能会出现诸如软腭咽闭合不全等并发症，这强调了预防措施的重要性。超声引导和肌电图辅助的使用可以帮助进行精确的注射，并最大限度地降低并发症的风险。此外，患者应接受适当的药物治疗并遵守治疗后的医嘱，以缓解症状。进行随访程序至关重要，以监测潜在的并发症，在某些情况下，可能需要专业的心理健康护理。需要进一步的研究来确定 BTX-A 注射治疗磨牙症和 TMJ 紊乱的安全性和有效性。本病例研究介绍了一位慢性磨牙症患者在接受 BTX-A 注射 3 天后出现软腭咽闭合不全的发展情况。
