This video demonstrates the surgical steps for treatment of stenosis of the external auditory canal occurring secondary to fibrous dysplasia of the temporal bone. After preserving as much of the external auditory canal skin as possible, the dysplastic lesion is drilled out until the tympanic membrane is reached. The remnant canal skin is then draped over the newly fashioned canal posteriorly while a preauricular pedicled skin flap is rotated inwards to cover the remaining bare bone anteriorly. By making an incision in the incisura of the pinna, one can rotate the pedicled preauricular full thickness skin flap into the external auditory canal resulting in a fairly acceptable cosmetic outcome. A stay suture on the base of the rotated preauricular skin flap prevents it from springing back out of the external auditory canal. The use of a full thickness skin cover for the exposed bone of the drilled external auditory canal is the key to preventing a restenosis due to fibrosis.
