Ingrown toenails (also called unguis incarnatus) are a common problem in the general population. In early 2020, the medical specialists' guideline "Ingrown toenail" was published in which the various treatment options are compared. Conservative treatment can be considered for stage I ingrown toenails. In stage II-III ingrown toenails and failing conservative treatment, operative treatment is recommended consisting of partial nail extraction from the ingrown nail edge in combination with destruction of the corresponding part of the matrix. There doesn't seem to be any reason to deviate from the advice in the case of a recurring ingrown toenail or an ingrown toenail in a patient with expected wound healing problems. A detailed elaboration of the guideline, which also contains a step-by-step operative approach, can be found on the Guidelines database (https://richtlijnendatabase.nl/).
