摘要钳形甲是一种以甲板异常增厚、远端横向过度弯曲为特征的甲板畸形,目前病因及发病机制尚未完全明确.根据甲板形态学的不同,钳形甲可分为寻常型钳形甲(喇叭样甲)、瓦片样钳形甲和折扇样钳形甲三种亚型.宽度指数、高度指数、曲率指数是评价钳形甲的严重程度和治疗效果的客观指标.根据钳形甲的分型和严重程度,临床上可采取相应的治疗手段,改善甲板的外形,缓解患者的临床症状.本文就钳形甲的分型、严重程度评估以及多种治疗方法做一概述.

abstractsPincer nails are a kind of nail deformity characterized by abnormal thickening and distal transverse overcurvature of the nail plate,whose etiology and pathogenesis are still unclear.According to the morphology of the nail plate,pincer nails can be divided into three subtypes:common pincer nail (trumpet nail),tile-shaped nail,and plicated nail.Width index,height index and curvature index are objective indicators to evaluate the severity and therapeutic effect of the pincer nails.According to the classification and severity of the pincer nails,appropriate treatment methods can be adopted to improve the appearance of the nail plate and relieve clinical symptoms of patients.This review systematically summarizes the classification of,evaluation of the severity of and several therapeutic methods for pincer nails.
