We present a previously undescribed occult malformation of the upper lip manifest by discontinuity of the orbicularis oris muscle. The relationship of this defect to our current concept of abnormal maxillary process development is discussed along with a proposal to extend the cleft lip phenotype.
我们报告了一种以前未被描述的上唇隐匿性畸形，表现为口轮匝肌连续性中断。本文讨论了这种缺陷与我们目前对上颌突异常发育概念的关系，并提出了扩展唇裂表型的建议。
