Previously published data on the mucosal cleavage lines were compared with data on the formation of scar tissue after palatoplasty and it was found that, in the palate and surrounding tissues, scar formation is light when incisions are parallel to the long axis of the cleavage lines but severe when incisions are made at right angles to the cleavage lines. A few cases were also found where jaw movement was severely restricted because of the formation of hypertrophic scar between the upper and lower alveolar ridges. It is therefore desirable that surgical incisions in thepalate and surrounding tissues be made parallel to the long axis of the mucosal cleavage lines.
将先前发表的关于黏膜裂开线的数据与腭裂修复术后瘢痕组织形成的数据进行比较，发现在腭部及周围组织中，当切口与裂开线的长轴平行时，瘢痕形成较轻；而当切口与裂开线成直角时，瘢痕形成严重。还发现少数病例因上下牙槽嵴之间形成肥厚性瘢痕而导致下颌运动严重受限。因此，在腭部及周围组织进行手术切口时，应与黏膜裂开线的长轴平行。
