Although pincer nail deformity (PND) treatment is time consuming independent of whether it is based on surgical or conservative procedures, long lasting beneficial results are found only after surgical intervention. Typically destruction of the lateral matrix horns either surgically or by phenol cauterization or even ablation of the matrix is performed. In the past these procedures mainly aimed at relief from pain; however, currently more patients ask for the preservation of the nail unit and a good cosmetic outcome. Today reconstructive results that meet the patient expectations are available. An adapted novel surgical method which will preserve the matrix horns while correcting the shape of the phalanx and preventing renewed adhesion of the nail bed to the phalanx is presented. Therefore the restoration of a normal width-to-length ratio of the nail plate with a cosmetically appealing result becomes possible. Surgical steps in an affected right toenail are presented.
尽管钳形甲畸形（PND）的治疗无论基于手术还是保守方法都很耗时，但只有手术干预后才能获得持久的有益效果。通常会通过手术、苯酚烧灼甚至切除甲床来破坏外侧甲床角。过去，这些手术主要旨在缓解疼痛；然而，目前更多患者要求保留指甲单元并获得良好的美容效果。如今已有能满足患者期望的重建效果。本文介绍了一种经过改良的新颖手术方法，该方法在矫正趾骨形状并防止甲床与趾骨再次粘连的同时，能保留甲床角。因此，恢复具有美观效果的正常指甲板长宽比成为可能。文中展示了对一例受影响的右脚趾甲进行手术的步骤。
