“…A 10 mm bone segment resection is considered safe for mandibular constriction, without periodontal or temporomandibular joint function contraindications [4,5]. Modified T-shape osteotomy for the correction of asymmetry and advancement was further described by Grime and Bleinkinsopp in 1990 [6]. Midline osteotomy is still considered to be an adjuvant in orthognathic surgery where transverse discrepancy must be corrected [7].…”

Background and Objectives: Correction of lower face asymmetry still remains challenging in maxillofacial surgery. This report describes techniques for the lateral transposition of the symphyseal segment to restore lower face symmetry while maintaining gender-related features in cis- and transgender patients. Materials and Methods: A retrospective review of medical records of 31 patients who attended for esthetic corrective surgery after orthodontic camouflage or orthognathic treatment, or during facial feminization of the lower face between June 2021 and June 2023 was performed. Result: All patients underwent lateralization genioplasty (with or without advancement or setback), either with or without narrowing T-osteotomy supplemented with necessary procedures in order to obtain proper facial balance and desired esthetical effects, such as bichectomy, liposuction, and face and neck lift. The mean asymmetry of the chin was 5.15 mm and was surgically corrected either by single segment lateralization or T-shape narrowing genioplasty depending on the gender and esthetical requirements. No complications were reported. Conclusions: Lateral shift genioplasty serves as a powerful tool in primary and secondary corrective surgery for lower face asymmetry that maintains gender-specific facial features. It may serve either as an additive to orthodontic camouflage or a way to correct previous orthognathic surgery pitfalls. The surgeon performing esthetic genioplasty associated with gender-specific expectations must be trained in facelift and facial liposculpting techniques in order to provide the best results and properly choose the right procedures for the right patients.

“…The remaining lateral bone segments are approximated to the midline and fixed. The resulting lateral bony step-off is resected for mandibular angle reduction [ 1 , 10 , 11 ]. Unlike T-genioplasty, in our M-genioplasty, a horizontal osteotomy is performed obliquely.…”

Lower facial contouring surgery using a novel method: M-genioplasty

et al. 2018

BackgroundMandibular contouring surgery to produce a more slender and small face has become popular, especially in East Asia. Narrowing genioplasty should be simultaneously performed with mandibular angle resection to achieve satisfactory results. In Korea, T-genioplasty has been frequently performed for chin narrowing. The authors developed a new, safe, and reliable method, termed M-genioplasty, that can provide a more slender and attractive lower face.MethodsFrom June 2013 to December 2017, 36 patients underwent M-genioplasty with mandibular angle resection for lower facial contouring. Horizontal and vertical osteotomies were performed obliquely. The resected bone segments were wedge-shaped. The remaining two bone segments were rotated and approximated centrally. The lateral mandible bony stepoff was trimmed off for mandibular angle resection.ResultsIn all patients, the facial contour sufficiently improved, and most patients were satisfied with the outcome. No severe complications took place during postoperative follow-up. ConclusionsM-genioplasty can provide more mandibular angle resection and can create a more acute chin angle without bone resorption than other methods, including T-genioplasty. M-genioplasty with mandibular angle resection is a safer, more accurate, and more reliable method for lower facial contouring.

“…Since 1942, with the Þ rst sliding advancement genioplasty that was described by Hofer, 1 various genioplasty techniques with various indications, advantages, and disadvantages have been developed for correction of microgenia and macrogenia ( Table 2). [1][2][3][4][5][6][8][9][10][11][12][13][14][15] Excess of the chin is the main clinical manifestation of macrogenia. When the problem is a vertical or sagittal bony excess, simple exposure of the anterior mandible through an intraoral approach and burring down the excess bone is not the best solution to the problem.…”

Introduction: The purpose of our study was to evaluate patients and technique and complete a review of the literature related to Zigzag genioplasty. Materials and Methods: To address the research purpose, the investigators designed and implemented a prospective clinical trial study. Seven osteotomy types (I–VII) are proposed for genioplasty that will permit one to decrease the 3-dimensions of the chin. These osteotomy designs are based on the displacement of bone fragments on the slopes of an inclined plane with a superior-medial direction. Results: All of the patients were satisfied with the esthetic results of their osteotomy. Based on presurgical and post-surgical facial analysis and clinical evaluations, no patients who received a Zigzag osteotomy suffered from permanent neurosensory deficiency, infection, hardware failure, severe pain, asymmetry, necrosis, massive hematoma, relapse, or suprahyoid muscle dysfunction. Conclusions: As a result, on the basis of our experience with 23 patients and after at least 1 year of follow-up with each one, the authors concluded that this technique is simple and easy to implement.
