Recent advances in our knowledge of the role of the ectomesenchyme in facial organogenesis, and the biology of fetal and infant cephalic development, supply valid arguments for the application of new principles in cheiloplasty for labial or labiomaxillary clefts. Instead of cutaneoplasty alone, the procedure involves anatomically selective muscle reconstruction of the nasolabial confines, a structure that is predominantly muscular. The alar portion of the cartilaginous mesethmoid ensures support of the nasolabial head of the orbicularis of the lip, and reconstitutes the anterior nasal vestibule by supplying the transverse muscle. Cheilomeso-ethmoidoplasty of the transverse and nasolabial muscles of the orbicularis of the upper lip is therefore as totally valid procedure.
我们对外胚间充质在面部器官形成中的作用以及胎儿和婴儿头部发育生物学的最新认识，为在唇裂或唇颌裂唇成形术中应用新原则提供了有力论据。该手术并非仅进行皮肤成形术，而是涉及对鼻唇界限进行解剖学上的选择性肌肉重建，鼻唇界限主要是一个肌肉结构。软骨性筛骨的鼻翼部分确保了唇轮匝肌鼻唇部的支撑，并通过提供横肌来重建前鼻前庭。因此，对上唇轮匝肌的横肌和鼻唇肌进行唇中筛骨成形术是一种完全有效的手术。
