It is suggested that levator veli palati muscle is the main muscle to keep eustachian tube open, and this muscle has distinct change in different cephalic morphologic pattern. 结果提示腭帆提肌是咽鼓管开放的主导肌,并且该肌随颅型变化拉力方向相应改变。
Two patients ( 3 ears) with abnormal patency of eustachian tube were treated with shunt operation of the tensor veli palatini muscle tendon. 采用腭帆张肌松解术治疗咽鼓管异常开放症2例(3耳)。
