title: Management of the ingrown toenail.
abstract: Ingrown toenail, or onychocryptosis, most commonly affects the great toenail. Many anatomic and behavioral factors are thought to contribute to ingrown toenails, such as improper trimming, repetitive or inadvertent trauma, genetic predisposition, hyperhidrosis, and poor foot hygiene. Conservative treatment approaches include soaking the foot in warm, soapy water; placing cotton wisps or dental floss under the ingrown nail edge; and gutter splinting with or without the placement of an acrylic nail. Surgical approaches include partial nail avulsion or complete nail excision with or without phenolization. Electrocautery, radiofrequency, and carbon dioxide laser ablation of the nail matrix are also options. Oral antibiotics before or after phenolization do not improve outcomes. Partial nail avulsion followed by either phenolization or direct surgical excision of the nail matrix are equally effective in the treatment of ingrown toenails. Compared with surgical excision of the nail without phenolization, partial nail avulsion combined with phenolization is more effective at preventing symptomatic recurrence of ingrowing toenails, but has a slightly increased risk of postoperative infection.
