Stapedial Artery

AbstractPersistence of the stapedial artery is rare. A case is presented in which the stapedial artery was found over the footplate during stapes surgery. The technical problems encountered are discussed.A wire prosthesis has previously been used in the presence of a persistent stapedial artery and we describe the use of an all Teflon prosthesis.A subsequent CT scan demonstrated the vessel in the middle ear.An outline of the embryology of the stapedial artery is given and the literature reviewed.

Ear Symptoms

Aberrant internal carotid artery in the middle ear is a rare anomaly. Myringotomy in a patient with this anomaly caused violent hemorrhage, requiring immediate packing and eventual ligation of the artery. The anomaly may represent the artery bulging through a dehiscent bony canal, or it may be due to traction on the developing carotid by a persistent stapedial artery. Various middle ear symptoms have been reported in earlier cases. Diagnosis is by angiography, and therapy is surgical.

Complete Section

Because of the important function of the embryologic stapedial artery, it is taken for granted by many surgeons that the finding of such a persistent artery in postnatal humans during middle ear surgery should urge maximal caution in order not to damage the artery. Often, discontinuation of the surgery is recommended. Yet this attitude is based on theoretic considerations rather than on any clinical evidence of complications following injury to this vessel. The present paper describes the embryology in relation to this specific aspect and reviews the literature on the persistent stapedial artery, emphasizing the papers dealing with injury to this vessel. In addition, we report 4 cases of persistent stapedial artery from the files of almost 20,000 patients in whom tympanotomy was performed. From all these data we conclude that injury to this artery or even complete section probably does not cause major, if any, postoperative sequelae, and that consequently, middle ear surgery is not necessarily hindered by the presence of this vessel.

Increased Sensitivity

Five subjects with normal middle ear mechanisms, and otosclerotic patients, before and after stapedectomy, matched the loudness of their voices to the loudness of a 125-cps-sawtooth noise. The results showed loudness matching functions with gradual slopes, less than 1.00, for the normal subjects and the patients prior to stapedectomy. Post-surgically, the loudness function for the patients increased in steepness to considerably more than 1.00. These results are explained, most logically, in terms of increased sensitivity of the altered middle ear to sound energy generated by the listener’s own voice.
