Treatment of<unk>  involves complete resection of the tract as well as intradural exploration. Prophylactic surgical removal of the<unk>  tract is beneficial for the patient, allowing neurological and bladder function to be maintained. Early surgical intervention results decreases the risk of infection and/or tumour progression – factors typically associated with delayed presentation of<unk> . Intradural exploration is necessary as excision of the entire tract, as well as any of its intradural connections, reduces need for further surgical intervention. The surgical technique involves ‘removing the cutaneous lesion in ellipse’. The tract of the<unk>  must then be explored and excised, with intradural lesions dissected. If not all epithelial tissue is removed, there is a possibility for the dermoid cyst to reoccur and require further operation. Further operations are limited by postoperative and post-infection scarring.
