Pincer nail: aesthetic concept in surgery.

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.
