[Plastic surgery by the Limberg-Dufourmentel method in the treatment of a pilonidal sinus. The anatomicosurgical considerations and an emblematic case].

Limberg-Dufourmentel's cutaneous flap may be used to fill in the loss of residual substance after the radical excision of sinus pilonidalis in the sacrococcygeal region. According to the authors, this technique enables some aspects of the locoregional anatomic conformation typically linked to the onset of this pathology to be modified, as well as permitting more accurate radical surgery. By way of example, the authors report the case of a 20-year-old subject with sinus pilonidalis who was successfully treated using this surgical technique.
