“…This contouring surgery is common in Asia, more so in women than in men. [1][2][3][4][5][6][7][8][9][10][11][12] An adequate reduction without injuring the intraosseous inferior alveolar nerve is a prerequisite to a successful outcome. Panoramic and cephalometric radiographs are often used for preoperative evaluation of the angle shape and size as well as the nerve.…”

Mandibular angle reduction is a popular contouring surgery in Asia. Avoidance of injury to the inferior alveolar nerve is crucial during these procedures. Anatomic data regarding the position of the nerve in the mandibular angle area are sparse. The purpose of this study was to use 3-dimensional computed tomographic data to evaluate the nerve in patients with prominent mandibular angles and to compare the nerve position with a normative group. A total of 28 female and 5 male adult patients who presented with a complaint of prominent angles or a "square-face" look, as well as 20 female and 22 male adult normal subjects were included, for a total of 150 hemimandibles for extraction of the inferior alveolar nerve. The nerve and the mandible were displayed. Point O was defined on the oblique line along the anterior cortex of ramus, where it intersected with a line extending from the alveolar arch. From the O point, linear distances were defined, including horizontal distances to the posterior cortex, oblique distances to the gonion, and the vertical distances to the inferior cortex. Mandibular width was defined as the distance between the 2 gonion points. Results demonstrated significant differences mainly in the oblique distances (ie, from the O point to the nerve [O1], from the nerve to the gonion [O2], and from the O point to the gonion [O1-O2]) in both female and male patients. The O2 distance was 23.69 mm versus 20.66 mm in women and 27.30 mm versus 23.28 mm in men (square face vs norm). The mandibular width was significantly larger in the male square-face patients, but the difference was not significant between the female groups. These results provide useful information for surgeons planning mandibular angle reduction. These findings suggest that the mandibular contouring procedure should be aimed at correcting regional osseous dysmorphology in the angle area and improving the relationship to the chin, rather than merely reducing the mandibular width.

“…In aesthetic surgery performed on Asian patients, usually a cortical bone segment from the outer mandibular table is used for bone graft to the chin. 2,3,8 It is widely known that cortical bone grafts revascularize slowly and incompletely compared with cancellous bone grafts. 15,16 In addition, it has been reported that the volumetric reduction rate of grafted bone from the outer mandibular table to a different mandibular region was approximately 20 percent.…”

“…[2][3][4][5][6][7] When the patient has a short lower face and requires a concomitant lengthening procedure of the chin, the use of autogenous bone grafts or alloplastic materials is presently the most popular approach to correct the problem. 2,3,5,8 To avoid the inherent disadvantages of these previous surgical methods when lengthening the chin, we devised a novel, simple, and reliable method that can effectively lengthen the chin and result in a natural and balanced appearance of the lower face.…”

“…Later, Converse described the mandibular angle ostectomy thorough both an extraoral and intraoral approach (Converse, 1977) for correction of the square face. Yang (Yang and Park, 1991), Baek (Baek et al, 2001) and Kim (Kim and Park, 2003) described refined techniques for correction of the prominent mandibular angle to overcome this disadvantage. "Long face" as mentioned here means that the lower 1/3 of the face is longer than usual.…”

“…Many researchers have attempted to correct a square face by various techniques after Legg's first report of masseteric hypertrophy in 1880 (Legg, 1880;Adams, 1949;Converse, 1977;Yang and Park, 1991;Deguchi et al, 1997;Satoh, 1998;Kim et al, 2001;Han and Kim, 2001;Kim and Park, 2003;Baek et al, 2001;Cui et al, 2008), but surgery for patients having a severe long or asymmetrical face with/without square a jaw is rarely reported in the literature. "Long face" as mentioned here means that the lower 1/3 of face is longer than usual but the other parts of face, such as the length of the middle and upper 1/3 of face, the height of zygomatic bone and the occlusion of teeth, are normal.…”
