唇裂手术中,常在前庭沟作松弛切口,并潜行分离上颌软组织,以便使唇裂易于缝合。这样做是否影响面中部的发育,目前颇有争论。许多医生不管唇裂裂隙宽度如何,都予以采用。Miland强调,在部分唇裂也应和完全唇裂一样作广泛的软组织潜行分离。Walker等则提出相反意见,认为这种操作可引起颌面部继发性发育畸形。为了探讨这个问题,作者设计了如下实验研究。将60只家兔分为4组,每组15只。第一组不作手术用作对照,第二组通过手术造成
Cleft lip surgery, often in the vestibular groove for incision, and sneak separation of the maxillary soft tissue in order to make the cleft lip easy to suture. Whether this will affect the development of the middle part of the face is controversial. Many doctors apply regardless of the cleft lip width. Miland emphasizes that in some parts of the cleft lip, extensive soft tissue slippage should also be performed in the same way as complete cleft lip. Walker, who put forward the opposite view, that this operation can cause maxillofacial secondary developmental malformations. In order to explore this issue, the author designed the following experimental study. Sixty rabbits were divided into four groups of 15. The first group without surgery as a control, the second group caused by surgery
