dc.description.abstractTwelve human stapes from temporal bones fixed by formalin were extracted. Different dimensions were measured by an electronic microscope with an accuracy of microm. These dimensions were as follows: (1) maximum diameter of stapes head parallel to the axis of footplate, 1088 microm (range, 857-1277 microm); (2) distance of main nutritional foramen to head surface, 398 microm (range, 250-833 microm); (3) stapes head to shoulders, 757 microm (range, 571-1000 microm), head to foramen, 1047 microm (range, 785-1500 microm), and head to lateral surface of footplate, 2612 microm (range, 1892-3400 microm); (4) anterior crus width at shoulder, 398 microm (range, 333-500 microm); minimum width of anterior crus, 251 microm (range, 214-350 microm); (5) posterior crus width at shoulders, 386 microm (range, 285-600 microm); minimum width of posterior crus, 191 microm (range, 142-300 microm); (6) maximum width of footplate near anterior crus, 371 microm (range, 321-500 microm), maximum width of footplate near the posterior crus, 411 microm (range, 357-611 microm), minimum width of footplate, 228 microm (range, 178-388 microm); (7) maximum width of ossicle, 2298 microm (range, 1928-3050 microm); (8) angle between crura, 19.5 degrees (range, 15-24 degrees ); and (9) diameter of foramen at the end of curve, 1343 microm (range, 1071-1888 microm).
