Management of ingrowing nail.

For decades, there has been debate about the cause of ingrown nail: is the nail plate or the periungual tissue at fault? There is no consensus and management relies on case-by-case analysis followed by tailored treatment. Conservative treatment should be attempted in children when the cause is transient (e.g., poor clipping) or the patient refuses surgery. Surgical treatments rely on two main approaches: either narrowing the nail plate, or debulking the soft tissue. It is up to the surgeon to select the most appropriate approach in each case. All procedures discussed in this chapter have high cure rates as long as they are properly performed. As with all surgical procedures, they are operator-dependent. Chemical cautery is the easiest and most versatile technique that may help in almost all instances for lateral ingrowth. For distal ingrowth and very hypertrophic and exuberant lateral folds, debulking with primary or secondary healing is most effective.
