Clinical experience in genioplasty has shown that high labial incisions heal with fewer scar bands than conventional deep labial incisions. In a prospective randomized trial, we compared 18 high labial curvilinear incisions with 27 high labial W-shaped ('royal') incisions for access and visibility during chin osteotomy. Both incisions were 3 cm wide. Maximal incision lengthening between two skin hooks was recorded with a ruler before closure, and there was no significant difference between the two. The maximum wound area between three skin hooks was photographed and computed, and showed a mean difference of 188.75 mm2 (t-test, P < 0.001), which corroborated the clinical findings that access and visibility were superior in the W-shaped incision group. Complications were few in both groups. We now use the high labial royal incision about 3.5 cm wide, with 90 degrees limb angle for complicated chin osteotomies and ostectomies. A smaller curvilinear high labial incision is used for simple advancement osteotomies.
颏成形术的临床经验表明，与传统的唇龈沟深部切口相比，高位唇龈沟切口愈合后瘢痕条索更少。在一项前瞻性随机试验中，我们比较了18例高位唇龈沟曲线切口与27例高位唇龈沟W形（“皇家”）切口在颏截骨术中的显露情况。两种切口均为3厘米宽。在关闭切口前，用尺子测量两个皮肤钩之间的最大切口长度，两者之间无显著差异。拍摄并计算三个皮肤钩之间的最大伤口面积，平均差异为188.75平方毫米（t检验，P<0.001），这证实了临床发现，即W形切口组的显露情况更好。两组并发症均较少。我们现在使用约3.5厘米宽、肢体角度为90度的高位唇龈沟皇家切口进行复杂的颏截骨术和骨切除术。较小的高位唇龈沟曲线切口用于简单的前徙截骨术。
