“…However, the mono-cortical absorbable plate system shows higher incidence of plate fracture compared to the bi-cortical plate fixation group [ 26 ]. When comparing the conventional absorbable plate system to the hybrid fixation system, plate fracture is observed only in the conventional absorbable plate system [ 27 ].…”

BackgroundBotulinum toxin-A (BTX-A) injection into muscle reduces muscular power and may prevent post-operative complication after orthognathic surgery. The purpose of this study was (1) to evaluate BTX-A injection into the masseter muscle on the prevention of plate fracture and (2) to compare post-operative relapse between the BTX-A injection group and the no injection group.MethodsSixteen patients were included in this study. Eight patients received BTX-A injection bilaterally, and eight patients served as control. All patients received bilateral sagittal split ramus osteotomy for the mandibular setback and additional surgery, such as LeFort I osteotomy or genioplasty. Post-operative plate fracture was recorded. SNB angle, mandibular plane angle, and gonial angle were used for post-operative relapse.ResultsTotal number of fractured plates in patients was 2 out of 16 plates in the BTX-A injection group and that was 8 out of 16 plates in the no treatment group (P = 0.031). However, there were no significant differences in post-operative changes in SNB angle, mandibular plane angle, and gonial angle between groups (P > 0.05).ConclusionsBTX-A injection into the masseter muscle could reduce the incidence of plate fracture.

“…The influence of proximal segment rotation has been addressed repeatedly (Proffit et al, 2012;Yang and Hwang, 2013) as a contributing factor for relapse. Methods of additionally stabilizing the proximal segment rotation and Gonial angle have not shown higher stability (Ueki et al, 2013).…”

Context: Using a reliable fixation method after ramus sagittal split osteotomy in order to reduce the chances of treatment relapse and condyle changes is still one of the most noteworthy issues discussed among maxillofacial surgeons. In this study, the results of the up-to-date papers were collected, which identify the effects of the fixation method on the post-operative results, to give the reader a comprehensive view of the new concepts. Evidence Acquisition: The most frequent mandibular surgeries, setbacks, and advancements via the bilateral sagittal split osteotomy technique were used for a literature search due to the abundance of related articles. Consequently, the following keywords were applied: sagittal split ramus osteotomy, orthognathic surgery, rigid fixation, non-rigid fixation, postoperative relapse, and postoperative stability. Results: The articles were classified according to the surgery procedure: mandibular advancement surgery or mandibular setback surgery. The relapse pattern can be divided into two categories: an early relapse, which is strongly related to the surgery procedure, and a late relapse, which can be attributed to the physiologic changes, such as a growth map. The contributing factors can be considered to be the following: a change in ramus in inclination, the mandibular plane, and the fixation type. Conclusions: Using rigid fixation techniques after bilateral sagittal split ramus osteotomy will optimize the stability, but this stability is not influenced by the method of this rigid fixation; although the most commonly suggested technique, bicortical screws, is in the inverted-L position
