目的为带血管蒂枕骨骨模瓣行枕颈融合术提供解剖学基础。方法在40侧经动脉罐注乳胶的成人尸体标本和8例头颈铸型标本(5例保留骨胳)上,解剖并观测枕骨骨膜的血供情况,并在标本上模拟术式设计。结果枕骨骨膜血供丰富,枕动脉的枕支和降支及椎动脉第三段各发出到枕骨的骨膜支为11.0±1.5、2.5±1.0、3.8±0.9支,骨膜支的外径为0.3~0.8 mm,骨膜支相互吻合成网;枕动脉枕支可游离长度为3.7±0.3 cm,外径2.1±0.2 mm;枕动脉降支可游离长度为2.1±0.2 cm,外径1.5±0.2 mm;椎动脉可游离长度为3.6±0.2 cm,外径2.6±0.4 mm。结论设计带血管蒂枕骨骨膜瓣转位行枕颈融合术具有可行性。
Objective To provide an anatomical basis for the occipitocervical fusion with vascular pedicle occipital mold. Methods 40 adult cadaveric caries injected with latex and 8 samples of head and neck cast (5 cases of preserved bone) were dissected and observed. The blood supply of the periosteum was dissected and observed, and the surgical design was simulated on the specimens. Results The occipital periosteal blood supply was rich. The periosteal branches of occipital and peroneal branches were 11.0 ± 1.5,2.5 ± 1.0,3.8 ± 0.9 in the third stage of occipital artery, and the outer diameter of periosteum was 0.3 ~ 0.8 mm, periosteal anastomosis network; occipital artery occipital branch free length 3.7 ± 0.3 cm, diameter 2.1 ± 0.2 mm; occipital artery descending branch free length 2.1 ± 0.2 cm, diameter 1.5 ± 0.2 mm; Vertebral artery free length of 3.6 ± 0.2 cm, diameter 2.6 ± 0.4 mm. Conclusions It is feasible to design transcranial occipital periosteal flap transposition for occipitocervical fusion.
