摘要
腭裂手术中，恢复腭帆提肌（ｌｅｖａｔｏｒｖｅｌｉｐａｌａｔｉｎｉｍｕｓｃｌｅ，ＬＶＰ）的位置及其两侧的完整性极为重要，为给临床提供有价值的参考数据，作者对２０侧健康成人、４侧健康新生儿及４侧唇腭裂新生儿头颈标本ＬＶＰ的解剖和６例胎儿头颈部标本组织学连续切片进行观察，证实ＬＶＰ位于软腭长度的４０％～７０％之间，在咽侧有肌纤维与咽上缩肌、咽腭肌相连续。该肌中份宽７．９ｍｍ，厚３．４ｍｍ，截面积２９ｍｍ￣２。成人ＬＶＰ与软腭的前倾斜角为３３．０°±５．１°，内倾斜角为４４．５°±４．６°。ＬＶＰ肌腹与咽鼓管软骨部内侧基底关系密切。该肌止点前部与咽腭肌一起止于腭正中筋膜起始处，其余与腭正中筋膜、悬雍垂肌周筋膜及对侧ＬＶＰ相融合。该肌血管来自腭升动脉及咽升动脉腭支，均由硬腭水平或该水平之上进入ＬＶＰ。ＬＶＰ由咽丛神经分支支配，该分支经咽旁间隙常与ＬＶＰ血管伴行，呈网状或干线状。
AbstractThe purpose of this study was to obtain more infor-mations about the levator veli palatini (LVP) musclethrough the dissection of head and neck cadaver samplesin 20 sides of normal adults, 4 sides of normal newbornsand 4 sides of cleft palate newborns and histological sec-tions in 6 normal fetuses. The results shown that themiddle part of LVP is 7. 9 mm in width, 3. 4mm inthickness and 29mmz on cross-section area. There aretwo angle relationship between LVP and the soft palate ,which are 44. 5° angle to midline sagittal section inwardand 33. 0°angle to coronal section forward. The LVPinsertion is between the 40% to 70% of the soft palatelength and only 25% insertion of LVP is located at thejunction area ofpalatal aponeurosis and fibromuscularcomponent of palatine raphe. Other parts of LVP insertion are merged into the midline fibromuscular component. The muscle has a close relationship with the medial parr of the carrilaglnous poriion of Eustachian tube.The LVP is supplied by the palatal branches of ascend-ing palatine artery and ascending pharyngeal artery,which are into the LVP at or above the level of the hardpalate. The LVP nerve branches coming from the pha-ryngeal plexus pass through the lateral pharyngealspace. The LVP reconstruction in cleft palate repair isdiscussed.
