Multiple palatoplasty techniques have been developed, but a technique involving a partial 2-layer soft tissue closure of the posterior hard palate and nasal floor and a 3-layer soft tissue closure of the soft palate with reorientation of the levator and tensor veli muscles across the midline has been the gold standard for cleft repair. This report describes a series of primary palatoplasties reconstructed with a middle layer of acellular collagen membrane that aided in maintaining closure between the oral and nasal cavities without the development of an oronasal fistula.
An acellular collagen membrane was placed between the muscular layer and the oral mucosa during primary palatoplasty. Six patients with primary cleft palatoplasty were identified and followed for 1 year (patient 1, a 10-month-old boy; patient 2, a 12-month-old girl; patient 3, a 12-month-old girl; patient 4, a 6-year-old boy; patient 5, a 12-month-old girl; and patient 6, an 18-month-old girl).
At 1 year, no oronasal fistulas had developed where augmentation with the acellular collagen membrane was used.
The use of an acellular collagen graft to aid in the 3-layer closure of primary palatoplasty surgery is a very effective strategy in primary and secondary healing and in preventing oronasal fistulation. The risk associated with the use of acellular collagen membranes appears nonexistent.
已开发出多种腭裂修复技术,但一种涉及硬腭后部和鼻底部分两层软组织闭合以及软腭三层软组织闭合且提肌和腭帆张肌跨中线重新定向的技术一直是腭裂修复的金标准。本报告描述了一系列采用无细胞胶原膜中间层重建的一期腭裂修复术,该中间层有助于维持口腔和鼻腔之间的闭合,且不发生口鼻瘘。
在一期腭裂修复术中,将无细胞胶原膜置于肌肉层和口腔黏膜之间。确定了6例接受一期腭裂修复术的患者,并对其进行了1年的随访(患者1,一名10个月大的男孩;患者2,一名12个月大的女孩;患者3,一名12个月大的女孩;患者4,一名6岁男孩;患者5,一名12个月大的女孩;患者6,一名18个月大女孩)。
1年后,在使用无细胞胶原膜进行增强的部位未发生口鼻瘘。
在一期腭裂修复手术的三层闭合中使用无细胞胶原移植物,在一期和二期愈合以及预防口鼻瘘方面是一种非常有效的策略。使用无细胞胶原膜相关的风险似乎不存在。
