The measurements of width index, height index, and curvature index were used for assessment of the curvature severity. Nevertheless, both sides of the nail root are buried subcutaneously, impossibility in measuring the width index correctly.
We developed a technique to measure the index under high-frequency ultrasonography (HF-USG).
There was good agreement between the HF-USG index and the result examined after surgery.
The observation on HF-USG helps to distinguish between ingrown nail and pincer nail. The HF-USG index will be useful in the examination and measurement of nail roots buried subcutaneously or nail penetration under the hypertrophic lateral nail fold, and comparing the effectiveness among treatments for pincer nail objectively.
宽度指数、高度指数和曲率指数的测量用于评估弯曲严重程度。然而，指甲根部的两侧都埋在皮下，无法正确测量宽度指数。
我们开发了一种在高频超声（HF-USG）下测量指数的技术。
HF-USG 指数与手术后检查结果吻合良好。
HF-USG 的观察有助于区分嵌甲和钳甲。HF-USG 指数将有助于检查和测量埋在皮下的指甲根部或肥厚侧甲襞下的指甲穿透，并客观比较钳甲的治疗效果。
