Abstract
Objectives : The aim of this study is to review the gross anatomy and variations of the stapedius muscle and its relations to the structures forming the retrotympanic area. In addition, this study will try to present a theory to explain the reason for these variations from a developmental point of view. ....-*.> Subjects and Methods : Thirty-five temporal bones were dissected, and studied utilizing a microscope and otoendoscopes. The muscle gross anatomy and its relations were studied. •..-.••. .",:_ - .". --. .• Results : Marked variations in the origin and size of the muscle, the course of its bony canal and its relation to the facial nerve canal were detected. These were mainly influenced by the sinus tympani development. These variations affected the length of the tendon and the pyramidal eminence. The presence of ectopic muscle bundles was confirmed in one specimen. Conclusion : The stapedius muscle anatomy can vary significantly from one temporal bone to another. In some situations, these variations can be of surgical importance worth enough to be recognized.
