To the Editor.—Stapedotomy1 is the recent trend in the surgery for otosclerosis, the reasons being less trauma to the inner ear, prevention of migration of prosthesis as well as eversion and inversion of the lining membrane of the vestibule, better long-term hearing results,1,2 and better hearing results at 4000 Hz.3

Better results at 4000 Hz and above were also noted in stapedectomy using the Mcgee4 piston, stapes mobilization,5 the Schuknecht fat and wire technique,6 and the Portman interposition technique.7 Similar results were obtained with heavier prostheses.8 The weight of a normal stapes is 1.5 to 2 mg (based on my study of 20 specimens9). To my knowledge, no data are available regarding higher frequencies when heavier prostheses, such as Ehmke, platinum wire, Robinson piston, polythene strut with stainless steel core, and Kos strut, were used. However, loss of stapedius function
