摘　　要：目的 :阐明颊肌的血液供应 ,为新型颊肌粘膜瓣设计提供解剖学基础。方法 :对 10具新鲜尸体标本 2 0侧面区进行解剖 ,从颈总动脉远心端注入红色乳胶 ,在 2具尸体标本面静脉内注入兰色乳胶。显露颊肌及其血管和神经。结果 :面动脉分别发出后颊支、下颊支和前颊支进入颊肌 ,后颊支与颊动脉相互吻合。上齿槽后动脉和眶下动脉发出上颊支分别进入颊肌上界的后部与前部。这些分支相互吻合。颊肌静脉在颊肌后部形成颊静脉丛 ,分 2～ 4支注入面静脉 ,或经颊静脉注入翼丛或上颌静脉。结论 :面动脉为颊肌的主要供血动脉。以进入颊肌任何一方血管为蒂的颊肌粘膜瓣均可存活。本文设计了 2种新的岛状颊肌粘膜瓣。Objective: To provide anatomical basis for the design of new buccinator myomucosal island flap.Methods: 10 fresh adult cadavers were injected with red latex solution in bilateral common carotid artery,and 2 of them were injected with blue latex solution in bilateral facial vein.The buccinator muscle and its vasculars and nerve were revealed and observed.Results: Originating from the facial artery,posterior buccal branch,inferior buccal branch and anterior buccal branch enter into the buccinator muscle.There are anastomosis between the posterior buccal branch and buccal artery.Originating from the lateral aspect of buccinator muscle,several veins converge into the buccal venous plexus,and drain into the facial vein or into the internal maxillary vein.Conclusion: The facial artery is the main blood supply to the buccinator muscle.Pedicled with any artery in this region,the buccinator muscosal island flap would always be viable.2 patterns of buccinator musculomucosal island flaps were designed in this study.
