摘要
在12例(24侧)儿童头颈部标本上观察了咽缩肌神经的起源、走行和分支分布。支配咽缩肌的神经为舌咽神经和迷走神经的分支混合组成,其主要组成平面在舌骨大角之上1.6±0.4cm。咽缩肌神经位置较为恒定,分支相对规则,两侧基本对称,其终末支通常有三种形式,位于舌骨大角平面上3.0±0.2cm。根据肌的神经分布特点,提出了蒂在上的改良咽后瓣手术的切口设计。
he innervation of the constrictor muscle of pharynx
was observed on both sides of 12 childcadavers.The pharyngeal plexus
is formed at the level of 1.6±0.4 cm above the greater horn ofhyoid
by the branches from the glosspharyngeal and vague nerves,and
terminated 3.0±0.2cmabove the greater horn level in three types,From
the.plexus tiny constant and symmetric branch-es rise to the
constrictor muscle of pharynx,An improved retropharyngeal flap with
an upsetpedicle was designed.
