Abstract:
Objective To evaluate the surgical corrective results of prominent mandibular angle with masseter muscle hypertrophy by using intraoral approach. Methods One hundred and twenty three cases with various degrees of prominent mandibular angle with masseter muscle hypertrophy were treated through intraoral approach. The basic surgical procedures included masseter muscle reduction (type Ⅰ), mandibular angle osteotomy (type Ⅱ) and angle-splitting osteotomy (type Ⅲ). The type Ⅰ was completed in 4 cases, type Ⅱin 16 cases, type Ⅲ + type Ⅰ in 56 cases, type Ⅲ in 19 cases, type Ⅲ + type Ⅰ in 9 cases, type Ⅲ + type II in 12 cases, type Ⅲ + type Ⅱ+ type Ⅰ in 7 cases. Genioplasty was simultaneously performed in 69 cases.Results The overwidth of the lower face was effectively corrected. The cosmetic results, as determined by both patients and surgeons, were good. No complications, such as facial never injury, or inferior alveolar never injury, occurred in any patients. Conclusions In order to reach good cosmetic results at the patients' lateral view and frontal view, considerations should be determined according to the degrees of the deformities and patient's desires, to choose suitable surgical procedures.
