以枕动脉为蒂颅骨外板骨(膜)瓣枕颈融合术的应用解剖

ObjectiveTo provide anatomic basis of cranial outer table flap pedicled with th e occipital artery for occipitocervical fusion.Methods Thecourse,branches and distribution of the occipital artery were observed on 40 adultcadavers perfuse d with latex and 8 cephalocervical vascular castings(5 castings preservedbones) .The operation was imitated on 2 cadavers.ResultsThe oc cipitalartery originate d from the external carotid artery.It ran through the occipital arterychannel o f temporal bone and perforated to the nucha.The perforaing point is 1.0±0.1 cmi nferior to the external occipital protuberance and 3.5±0.2 cm lateral to the me d ianplane.Its external diameter at the point of penetration into the subcutaneou s tissue is2.1±0.2 mm.The occipital artery ran upward between superficial fasc i a and galeaaponeurotica and gave off branches to nourish the soft tissue(the oc ciput,opisthoticregion,opisthotic and calvaria),pericranium and cranial outer t able.ConclusionCranialouter table flap pedicled with the occipital artery could be used in occipitocervicalfusion.
