“…Two other recent studies highlighted a status improvement in patients with Meige syndrome to BTX-A injection into the superficial SH [23,24]. Meige syndrome is a rare pathology that consists of idiopathic blepharospasm and oromandibular dystonia [33].…”

“…The other studies included in this systematic review targeted different pathologies. The study protocols were different, but all revolved around the same final aim, the chemodenervation of the digastric muscle, in order to obtain positive results in the case of anterocollis (AC) [21], facial synkinesis [22], or Meige syndrome [23,24]. Research published in 2021 used BTX-A as a treatment for AC posture, a complex subtype of cervical dystonia and the most infrequent of its abnormal head positions [21].…”

“…The injection method of BTX-A involved muscle palpation, the guidance of electromyography (EMG), US, or both. Studies that included the injection of several deep muscle groups, such as the digastric, considered that EMG and US are both safe and effective methods for injecting BTX-A [21,[23][24][25][26]. A technical note published in 2015 emphasized the importance of screening for ABDM anatomical variations before BTX-A injection in order to prevent undesired adverse effects of BTX-A injection [35].…”

The present research aimed to review the clinical applications of botulinum toxin-A (BTX-A) injection into the anterior belly of the digastric muscle (ABDM) and to highlight the potential role of the BTX-A injection into ABDM in preventing postsurgical relapse. Five Class II malocclusion patients who underwent orthognathic surgery received BTX-A injections into both ABDM for the prevention of postoperative relapse. The relapse was evaluated using lateral cephalometric radiographs by comparing the postoperative cephalometric analyses at two different time points, postoperatively at 2 weeks (T1), and long-term, at 9 months after the surgical intervention (T2). The results demonstrated no significant differences between T2 and T1 for the Selle-Nasion-point A (SNA) angle, Selle-Nasion-point B (SNB) angle, point A-Nasion-point B (ANB) angle, mandibular length, and sagittal mandibular position. The patients exhibited stable occlusion without any signs of relapse after the surgery. A single BTX-A injection into the ABDM can effectively prevent postoperative relapse in Class II malocclusion patients, following orthognathic surgery. From a clinical perspective, in case of optimal dosage and procedure, BTX-A injection could be considered as the primary option for the prevention of postsurgical relapse for Class II malocclusion patients.

“…Two of these reactions were triggered by levosulpiride use and were reversed upon cessation of this drug, and one was functional in nature. Fernández-Pajarín et al 3 reported a good response of hyoid dystonia to two sessions of botulinum toxin injection. Norby et al 4 reported a large series of hyoid dystonia in which a change in speech resonance was observed in all patients, and dysphagia was reported in 73.3% of patients, although tremor was not described.…”

ObjectiveThis study aims to evaluate the effects on bite force and muscle thickness of the botulinum toxin (BoNT) injection for patients with sleep bruxism (SB) by comparing injections into the masseter muscle only and both the masseter and the anterior belly of the digastric muscle (ABDM) in a clinical trial.MethodsTwelve SB patients received BoNT‐A injections using US‐guided techniques into the masseter muscle only (Group A), while the remaining 12 SB patients received injections into both the masseter and ABDM (Group B). Bite force and muscle thickness were measured before injection, as well as 1 and 2 months after injection.ResultsThe bite force and masseter muscle thickness decreased in both Group A and Group B before injection, and at 1 and 2 months after injection. However, there was no significant difference (p > .05, repeated measures analysis of variance) between the two groups, and there was also no significant difference in ABDM thickness (p > .05, repeated measures analysis of variance).ConclusionThis study is the first to assess the short‐term effects of BoNT injected into ABDM for SB control. Results show no influence on SB reduction, suggesting the need for further research on BoNT's effectiveness in controlling intense ABDM contractions during sleep and assessing suprahyoid muscle potential impact on rhythmic masticatory muscle activity occurrence.
