摘要
解剖了30例正常婴幼儿,7例腭裂婴幼儿的头部标本。结果显示腭裂标本咽鼓管软骨的质地较同龄者软,腭帆提肌吊带中断且前移位,止点相对固定。该肌的咽鼓管软骨部几乎位于咽鼓管下壁下方。经分析比较,作者认为腭裂患者的腭帆提肌不具有力收缩和上抬咽鼓管软骨的能力,造成鼓咽管通气障碍,导致中耳炎。腭裂修复应恢复良好的咽鼓管通气功能,术时须将腭帆提肌后移并重建肌肉吊带。
Slitting sling,fixed insertion and overlapping with inferior wall of eustachiantube were observed of the levator veli palati muscle(LVP)in cleft palate children.In such cases the LVP muscle was not able to contract and raise the eustac-hian cartilage effectively.Thus the incidence of ottis media with effusion maybecome significantly high.In order to obtain good ventilatory function of eustach-ian tube,the LVP muscle should be retrogradely placed and its sling reconstructedduring the repair of cleft palate.
