Abstract
Middle ear variations have a reported incidence of about 5.6% (28/500 temporal bones). This muscle may be doubled or absent., or its tendon may fail to develop. Ectopic muscle rests were found in 19/500 bones near the facial nerve and are believed to be derived from mesenchyme originating from the hyostapedial ligament. Syn.: m. Pyramido-stapéal, Steigbügelmuskel.
