ORL J Otorhinolaryngol Relat Spec. 1988;50(6):382-4. doi: 10.1159/000276017.


A 43-year-old female had bilateral otosclerosis with a persistent stapedial artery in the left ear which measured approximately 0.4 mm in diameter, lying on the floor of the tympanic cavity, running between the crura of the stapes and entering the facial canal. Stapedectomy was performed following section of this vessel and controlling the hemorrhage. Satisfactory hearing gain was obtained in both ears after stapedectomy.
