Abstract: Objective To explore a new surgical approach for the renovation of laryngotracheal stenosis. Methods the anatomical structures of the anteroventral portion of the digastric muscle along with the blood supply, innervation and periosteal coverage of the mandibular were investigated by observing 23(46 sides) cadaver. Results The anteroventral portion of the digastric muscle rise from the fossae digastrica at the angle of 30.4°±3.5°. Its length was (4.8+0.7) cm and the periosteal coverage averaged (111.6+28.2) mm2. The puncta of rami digastricus stats (2.4+0.7) cm from the arteriae submentalis. Mylohyoid nerve together with rami digastricus enters the muscular tissue. Conclusion Designed with reference to sternocleidomastoid clavicular periosteal flap, the periosteal flap of the anterovent of the digastric muscle-mandible may offer a new way for largngotracheal renouation.
