Abstract

External auditory canal (EAC) stenosis is commonly seen in patients with fibrous dysplasia of the temporal bone. Postoperative canal restenosis is more likely to be encountered after initial surgical management. We present a case of monostotic fibrous dysplasia of the temporal bone with EAC invasion in a 37-year-old man who presented with recurrent canal stenosis and resultant conductive hearing loss after several rounds of revision surgery. The technique of using a composite Foley catheter as a stent gave promising results in terms of improving the canal’s patency and closing the preoperative air-bone gap in the hearing threshold after 18 months of follow-up. This suggests that long-term stent use with a Foley catheter offers a treatment of choice to prevent such troublesome canal restenosis.
