Ingrowing toenails most commonly affect young adults with congenital malalignment of the great toenails. Improper nail cutting may lead to embedding of a nail edge, causing inflammation and granulation tissue formation. Hyperhidrosis is frequently associated. The aim of treatment for ingrowing toenails is to extract the nail edge that is ingrowing and prevent further penetration of nail fragments into the lateral folds. To accomplish this, the lateral nail plate can be lifted by using a cotton pack or by inserting a gutter splint along the lateral nail margin. The width of the nail plate can also be reduced by surgical or chemical (phenolization) removal of the lateral nail matrix
