Restoration of the continuity of the posterior muscular ring and production of adequate palatal length have been the prime objectives cleft surgeons have sought in their drive to obtain good speech. Twelve patients with cleft palates varying from incomplete clefts of the secondary palate to wide clefts associated with unilateral and bilateral lip deformities have been repaired utilizing an early radical soft palate release from the hard palate. The element not stressed in prior early soft palatoplasties is this full-thickness release of the soft palate from its abnormal insertion along the cleft. This allows the reconstructed soft palate to function independently as part of the posterior muscular ring. This approach also partly corrects the orientation of the levator muscles and avoids internal scarring in the soft palate caused by extensive dissection. The series of cases reported here is small, and although the results are very encouraging, this approach cannot be claimed as a panacea for all the problems of soft and hard palate repair. The sound fundamental principle of reconstructing the functional unit without regard to filling the hole is the essence of this approach. Hard palate closure is delayed until the functional unit (the soft palate) is well-established as part of the posterior muscular ring. To do this requires a radical separation of the hard and soft palate clefts both surgically and conceptually. The benefits indicated in this series seem to follow directly from these principles. The cases repaired by the island soft palatoplasty have long, mobile soft palates with the correct orientation and relationship of muscles. They have developed good palatal motion, velopharyngeal competence, and good speech.
恢复后肌环的连续性并产生足够的腭长度一直是腭裂外科医生在追求良好语音过程中所追求的主要目标。利用早期从硬腭彻底松解软腭的方法,对12例腭裂患者进行了修复,这些患者的腭裂情况各不相同,从软腭不完全腭裂到伴有单侧和双侧唇畸形的宽腭裂。以往早期软腭成形术中未强调的要素是软腭从沿腭裂的异常附着处进行全层松解。这使得重建的软腭能够作为后肌环的一部分独立发挥作用。这种方法还部分纠正了提肌的方向,避免了因广泛解剖导致的软腭内部瘢痕形成。这里报道的病例系列规模较小,虽然结果非常令人鼓舞,但这种方法不能被宣称是解决软硬腭修复所有问题的万灵药。不考虑填补缺口而重建功能单元的合理基本原则是这种方法的精髓。硬腭关闭延迟到功能单元(软腭)作为后肌环的一部分稳固建立之后。要做到这一点,需要在手术和概念上对硬腭和软腭裂进行彻底分离。本系列中显示的益处似乎直接源于这些原则。采用岛状软腭成形术修复的病例,软腭长且可活动,肌肉方向和关系正确。他们已发展出良好的腭运动、腭咽闭合功能和良好的语音。
