A case of persistent stapedial artery is presented. The patient was a 49‐year‐old man who had suffered from tinnitus in the left ear and bilateral hearing impairment for 20 years. The preoperative audiological examinations showed considerable combined hearing loss, suggesting middle ear anomalies or otosclerosis. An exploratory tympanotomy on the left ear was performed, and complete fixation of the stapedial footplate and a small vessel running vertically on the footplate were observed. By reconstructive surgery using a prosthesis, postoperative hearing improved. The histological examination of the removed portion of the stapes showed an otosclerotic lesion. Cases of persistent stapedial artery found in the literature were discussed from the clinical and embryological viewpoint.
