The purpose of this study was to obtain more informations about the levator veli palatini (LVP) muscle through the dissection of head and neck cadaver samples in 20 sides of normal adults, 4 sides of normal newborns and 4 sides of cleft palate newborns and histological sections in 6 normal fetuses. The results shown that the middle part of LVP is 7.9 mm in width, 3.4mm in thickness and 29mm2 on cross-section area. There are two angle relationship between LVP and the soft palate, which are 44.5 degrees angle to midline sagittal section inward and 33.0 degrees angle to coronal section forward. The LVP insertion is between the 40% to 70% of the soft palate length and only 25% insertion of LVP is located at the junction area of palatal aponeurosis and fibromuscular component of palatine raphe. Other parts of LVP insertion are merged into the midline fibromuscular component. The muscle has a close relationship with the medial part of the cartilaginous portion of Eustachian tube. The LVP is supplied by the palatal branches of ascending palatine artery and ascending pharyngeal artery, which are into the LVP at or above the level of the hard palate. The LVP nerve branches coming from the pharyngeal plexus pass through the lateral pharyngeal space. The LVP reconstruction in cleft palate repair is discussed.
本研究的目的是通过对20侧正常成年人、4侧正常新生儿和4侧腭裂新生儿的头颈部尸体样本进行解剖以及对6例正常胎儿进行组织学切片，来获取更多关于腭帆提肌（LVP）的信息。结果显示，LVP中部宽度为7.9毫米，厚度为3.4毫米，横截面积为29平方毫米。LVP与软腭之间存在两种角度关系，向内与矢状中线切面呈44.5度角，向前与冠状切面呈33.0度角。LVP附着于软腭长度的40%至70%之间，只有25%的LVP附着位于腭腱膜与腭缝纤维肌肉成分的交界处。LVP附着的其他部分融入中线纤维肌肉成分。该肌肉与咽鼓管软骨部分的内侧密切相关。LVP由腭升动脉和咽升动脉的腭支供血，这些血管在硬腭水平或其上方进入LVP。来自咽丛的LVP神经分支穿过咽外侧间隙。文中还讨论了腭裂修复中LVP的重建。
