Histological sections of tissue removed from three incomplete cleft lips at the time of repair, a nature's scar line, and a noncleft lip were examined serially in the horizontal and saggital planes. The findings confirm previous data from electrical stimulation studies of clefts and a three-dimensional histological model of the orbicularis oris in a complete cleft lip. There is a disorganized mass of muscle fibers with numerous dermal insertions and no evidence of well-defined muscle bundles running parallel to the cleft margins. The fibers are somewhat hypoplastic and less abundant than those present in noncleft lips.
对修复时取自三个不完全唇裂、一条自然瘢痕线以及一个非唇裂的组织进行组织学切片，在水平和矢状平面上进行连续检查。这些发现证实了先前关于唇裂电刺激研究以及完全唇裂中口轮匝肌三维组织学模型的数据。存在一团杂乱的肌纤维，有大量真皮附着，没有证据表明有明确的肌束平行于唇裂边缘排列。这些纤维有些发育不全，且比非唇裂中的纤维数量少。
