Objective.为了评价手术效果，我们建立了一种新的方法，使用Hausdorff距离来描述鼻形态，并分析了唇裂整形术后的鼻形态。本文对30例单侧唇腭裂患者行唇腭裂修复术后的鼻孔进行了评估。通过视觉评价、面积比、周长比、纵横比和Hausdorff距离评估左右侧之间的相似性。同时比较15例术前使用Hotz钢板治疗的患者与15例未使用Hotz钢板治疗的患者术后鼻孔形态。Hausdorff距离与视觉评价显著相关。对于有和无Hotz钢板治疗的组，治疗组的视觉评价较高，Hausdorff距离显著降低。使用Hausdorff距离获得的形态学测量最接近视觉评价，使用Hausdorff距离进行评估表明，使用Hotz板有助于保持唇成形术后鼻孔的对称性。(Oral外科口腔医学口腔病理学口腔放射学2012;114：704-711）
Objective. To evaluate surgery results, we established a novel method to digitize nasal morphology with the use of Hausdorff distance and analyzed nose morphology after cheiloplasty.Study Design. We evaluated the naris after primary cheiloplasty of 30 unilateral cleft lip and palate patients. Similarity between left and right sides was assessed by visual evaluation, area ratio, perimeter ratio, aspect a/u ratio, and Hausdorff distance. The postoperative naris morphology was also compared between 15 patients treated with a Hotz plate before surgery and 15 not treated.Results. Significant correlation with visual evaluation was found for Hausdorff distance. For the groups with and without Hotz plate treatment, the visual evaluation was higher and Hausdorff distance significantly lower in the treated group.Conclusions. The morphologic measurement obtained using the Hausdorff distance was the closest to visual evaluation, and assessment using Hausdorff distance suggested that using a Hotz plate helps retain the symmetry of the nares after cheiloplasty.
