摘　　要：目的:为带胸锁乳突肌锁骨头为蒂锁骨瓣移位术提供解剖学基础。方法:在40侧成人尸体标本上,解剖观察胸锁乳突肌的形态,血供来源,分布特点及其与锁骨的关系;2例新鲜标本上作模拟术式。结果:胸锁乳突肌血供丰富,其锁骨头的主要血供为甲状腺上动脉胸锁乳突肌支,外径1.52±0.1mm,其入肌点相当于胸锁乳突肌前缘中下1/3交界处;锁骨内侧端主要血供由甲状腺上动脉胸锁乳突肌支(82.5%)的骨膜支及其与颈横动脉(10%)或肩胛上动脉的锁骨支(2.5%)构成的丰富吻合支供血。结论:以胸锁乳突肌锁骨头带半片锁骨瓣转位修复下颌骨缺损是可行的。Objective： To provide anatomic base for transposition of clavicular bone flap pedicled with sternocleidomastoid muscle.Methods：The shape,blood supply and distribution of the stemocleidomastoid muscle and its relation to the clavicle were observed on 40 adult cadavers. And simulative surgery was employed on 2 fresh adult cadavers, Results： The clavicular head was supplied by the stemocleidomastoid branches from the superior thyroid artery which outer diameter is（ 1.52±0.1） nterior and midst and 1/3 posterior.The proximal end of clavicle was mainly supplied by the anastomosis banches conist of the periosteal branch of sternocleidomastoid branches from the superior thyroid artery（82.5% ） and the transverse cervical atery（ 10% ） or the clavicular branch from the supseapular artery（2.5 % ）. Conclusion： The transposition of the partial clavicular bone flap pedicled with sternocleidomastoid muscle is suitabe for repairing mandibular defect.
