IN JANUARY 1965, we evolved a new prosthesis for use in stapes surgery.1 This took the shape of a spring, made of stainless steel wire and prepared on a Schuknecht die. We advocated its adoption in preference to other well-known prostheses, because, in theory, it could protect the labyrinth and fulfill at least one of the functions of the stapedius muscle, which is usually severed in stapedectomy operations (Fig 1).
The excellent results obtained by stapedectomy in otosclerotic deafness tended at first to overshadow some of the side-effects. But with the passing of time, more attention has been given to perfection of technique and to better hearing results, especially in the drop for high tones which frequently occurs after stapedectomy.2,3
The importance of the stapedius muscle was known to clinicians in the last century. Muller in 1838 described the protective role played by the middle ear muscles whenever
