目的 :为带血管蒂锁骨内侧端骨膜、骨瓣转位术提供解剖学基础。方法 :在 30侧成人尸体标本上 ,观察了甲状腺上动脉胸锁乳突肌支的走行、分支、分布及吻合 ,并在标本上模拟术式设计。结果 :恒定起源的甲状腺上动脉胸锁乳突肌支游离长度达 8cm以上 ,外径 1.4± 0 .3mm。 90 .0 %终支直接达锁骨 ,10 .0 %与颈横动脉 (肩胛上动脉 )锁骨支吻合间接达锁骨。结论 :以甲状腺上动脉胸锁乳突肌支为蒂锁骨内侧端骨膜、骨瓣转位修复下颌骨缺损或行颈椎前方植骨融合具有可行性。
Objective: To provide anatomical basis for the pedicle of periosteum with vascularized clavicle and transposition of bone flap. Methods: The adult cadaver specimens of 30 sides were observed on the thyroid artery sternocleidomastoid branch of the line, branch, distribution and anastomosis, and in the specimen simulation of surgical design. Results: The constant origin of the thyroid artery sternocleidomastoid branch free length of more than 8cm, diameter 1.4 ± 0. 3mm. 90 .0% Final support directly to the clavicle, 10.0% and transverse cervical artery (suprascapular artery) clavicle anastomosis indirect access to the clavicle. CONCLUSIONS: Using the sternocleidomastoid branch of the thyroid artery as the medial periosteal pedicle and transposition of the bone flap to repair mandibular defects or anterior cervical spine fusion is feasible.
