“…Nevertheless, among them, the increased tension of the paramandibular soft tissues, including SH, could be a decisive factor in the relapse [29]. These findings are strengthened by a study published in 2021 [13], which showed that ABDM suffers postoperative dimensional changes, in terms of thinning and elongation, with these findings being also incriminated in the surgical relapse.…”

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.

“…Orthognathic surgery could induce dimensional changes of the ABDM, associated with increased length and decreased width, as muscular alterations are often implicated in surgical relapse [13]. To avoid recurrence corrections for Class II malocclusion, different surgical techniques have been discussed.…”
