Abstract

OBJECTIVE

To evaluate the reproducibility and accuracy of a new, easy-to-use volumetric assessment of the alveolar cleft.

DESIGN

Twelve cone-beam computed tomography (CBCT) datasets of patients with a unilateral cleft lip, alveolus, and palate were evaluated by two investigators. Residual alveolar cleft calcified volume one year after surgery was analyzed by using standardized landmarks to determine the borders of the cleft defect and semi-automatically segment the alveolar cleft defect.

RESULTS

The Dice-coefficient between observers for the segmented preoperative alveolar cleft defect was 0.81. Average percentage of residual alveolar cleft calcified material was 66.7% one year postoperatively.

CONCLUSIONS

This study demonstrates a reliable and practical semi-automatic three-dimensional volumetric assessment method for unilateral clefts using CBCT.

摘要

目的

评估一种新的、易于使用的牙槽裂容积评估方法的可重复性和准确性。

设计

通过两位研究者对 12 例单侧唇裂、牙槽裂和腭裂患者的锥形束 CT（CBCT）数据集进行评估。使用标准化的解剖标志确定裂隙缺陷的边界，并半自动分割牙槽裂缺陷，以分析术后 1 年剩余牙槽裂的钙化体积。

结果

观察者之间用于分割术前牙槽裂缺陷的骰子系数为 0.81。术后 1 年，残余牙槽裂钙化材料的平均百分比为 66.7%。

结论

本研究使用 CBCT 证明了一种用于单侧裂隙的可靠且实用的半自动三维容积评估方法。
