目的 为临床上较为棘手喉气管狭窄提供新的修复方法。方法 研究23具（46侧）福尔马林固定的头颈部标本的二腹肌前腹的形态学特征并测量其相关的解剖结构。结果 二腹肌前腹以（30.4°±3.5°）的角度起于下颌骨二腹肌窝内，其长度为（4.8±0.7），颏下动脉二腹肌血管支在距颏下动脉起始点（2.4±0.7）cm发出，下颌舌骨神经伴随血供入肌，该肌附着骨膜面积为69.6~155.4（111.6±28.2）mm2。结论 根据颏下动脉皮瓣和胸锁乳突肌锁骨骨膜瓣的制备方法和二腹肌前腹相关的解剖学数据，设计以二腹肌前腹和颏下动脉为蒂的下颌骨骨膜瓣修复喉气管，有良好的解剖学条件。
Objective To provide a new repair method for the more throat laryngeal tracheal stenosis. Methods Morphological characteristics of 23 cases (46 sides) formalin-fixed head and neck specimens of the anterior abdominal quadrant were measured and their related anatomical structures were measured. Results The anterior abdominal of the anastomosis started at the angle of (30.4 ° ± 3.5 °) in the quadriceps of the mandible and its length was (4.8 ± 0.7). The blood vessels of the submucous artery of the submental artery were at the starting point of the submental artery (2.4 ± 0.7) cm. The mandibular hyoid nerve was accompanied by blood supply to the muscle. The periosteal area of the muscle was 69.6-155.4 (111.6 ± 28.2) mm2. Conclusion According to the preparation method of submental artery flap and sternocleidomastoid clavicle periosteal flap and anatomical data related to the anterior segment of the anterior quadrant of the abdominal muscles, a mandibular periosteal flap pedicled with the anterior abdominal and submental arteries of the abdominal muscles is designed Laryngeal trachea, with good anatomical conditions.
