Canal wall down technique may offer excellent exposure during operation and remove the lesion more easily, but may result other serous problem such as chronically draining cavity, dizziness, difficulty with fitting of a hearing aid and need for regular care of the mastoid bowl. Among of them, postauricular mastoid fistula is the unusual complication case that difficult to treat due to the surrounding necrotic skin edge. Recently many various techniques are introduced to repair mastoid fistula including simple closure, bone or cartilage graft and muscle flap coverage. However these techniques have their limitations in reconstruction mastoid fistula as well as some disadvantages. We report a method of superficial temporalis fascia transposition flap and external auditory canal reconstruction using silastic sheet has been performed successfully without complication. We consider these techniques to be a satisfactory procedure in postauricular cutaneous mastoid fistula which was caused by previous canal wall down mastoidectomy.
