“…6 Martinez et al 7 reported in 1999 that there is better regeneration of symphysis thickness in patients younger than age 15 than in older nongrowing individuals. More recently, Frapier et al 8,9 suggested that early genioplasty could improve the direction of mandibular growth and might increase nasal breathing because of improved lip function, but these assertions were based on samples that were too small and diverse for broad generalization.…”

Objective: To evaluate the role of age as a moderator of bone regeneration patterns and symphysis remodeling after genioplasty. Method: Fifty-four patients who underwent genioplasty at the end of their orthodontic treatment were divided into three age groups: younger than 15 years at the time of surgery (group 1), 15 to 19 years (group 2), and 20 years or older (group 3). Twenty-three patients who did not accept genioplasty and had a follow-up radiograph 2 years after the end of their orthodontic treatment were used as a control group. Patients were evaluated at three time points: immediate preoperative (T1), immediate postoperative (T2,) and 2 years postsurgery (T3). Results: The mean genial advancement at surgery was similar for the three age groups, but the extent of remodeling around the repositioned chin was greater in group 1, less in group 2, and still less in group 3. Symphysis thickness increased significantly during the 2-year postsurgery interval for the three groups, and this increase was significantly greater in group 1 than in group 3. Remodeling above and behind the repositioned chin also was greater in the younger patients. This was related to greater vertical growth of the dentoalveolar process in the younger patients. There was no evidence of a deleterious effect on mandibular growth. Conclusion: The outcomes of forward-upward genioplasty include increased symphysis thickness, bone apposition above B point, and remodeling at the inferior border. When indications for this type of genioplasty are recognized, early surgical correction (before age 15) produces a better outcome in terms of bone remodeling. (Angle Orthod. 2015;85:360-373.)

“…Since the osteotomy cut was made inferior to point B in Group A and superior to point B (supramentale) in Group B, SNB was increased only in Group B. Frapier 17 and Sati 18 too observed augmentation of SNB with advancement genioplasty during puberty. Labiomental angle between the chin and lower lip, when acute, causes deepening of mentolabial fold but a vertically long chin can have an underdeveloped mentalelabial fold.…”

“…Therefore, when indicated for cosmetic concerns, it appears useless to wait for a later age. It improves facial aesthetics, which can be a serious psychosocial handicap, even early in life (Chamberland et al, 2015). It allows redirection of mandibular growth reducing the open bite in wide angle class II patients (Precious and Delaire, 1985; Frapier et al, 2010). It enables lip competence and upper airway recalibration, therefore increasing velopharyngeal and linguopharyngeal spaces (Frapier et al, 2011; Bedoucha et al, 2015).…”

Hallermann-Streiff syndrome (HSS) is a rare congenital disorder that mainly affects head and face development. We described the different patterns of the disease throughout the whole growth period and provided innovative treatment steps. Indeed, early genioplasty and dental implantation before growth completion were performed. These steps allowed to improve facial growth and to provide orthodontic anchorage, respectively. Complementary orthognathic surgery achieved satisfactory occlusion and refined aesthetics. We believe such an approach could be considered as a relevant treatment modality to complete multidisciplinary care in patients with HSS.
