“…Most of the data concern incidental findings during postmortem examination or during middle ear (mostly stapes) surgery. A prevalence of about 1 in 5,000 to 1 in 10,000 is estimated.toIn merely 12 cases (including the present cases 2 and 3) this was an isolated finding, while the other cases showed multiple congenital anomalies (see Tabl~8,14,16,18,19,23,24,[27][28][29][32][33][34][35][36][37]. Ten cases, including the present case 4, had documented bilateral stapedial arteries.…”

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.

“…Hough (1958), in his series of 500 tympanotomies, encountered one case of suprastructure fixation, as did Ombredanne (1960) in his series of 100 ears with minor congenital malformations. Gerhardt and Otto (1970) described two cases out of 1000 patients. In a recent series, Teunissen and Cremers (1990) described one case of suprastructure fixation out of 32 cases with isolated congenital stapes anklyosis.…”

Isolated congenital anomalies of the ossicles are rare. The majority of cases of congenital conductive hearing loss secondary to middle-ear anomalies have other associated defects, such as atresia, microtia and craniofacial deformities.We present a rare case of isolated congenital stapes suprastructure fixation, where a monocrural stapes with a mobile footplate was attached to the promontory by bony synostosis. There was no stapedius muscle nor pyramidal process. The incus and malleus were of normal configuration. Mobilization of the stapes from the promontory resulted in improvement in hearing. We believe this is the first reported case of such an abnormality. A review of the world literature of isolated stapes suprastructure ankylosis and the classifications of minor congenital anomalies are discussed.
