“…A bony obliteration of the oval window in a patient who had already lost his hearing was described for the first time in the 18th century. In 1894, Politzer introduced the term otosclerosis as an entity, but it was only in 1956 that otosclerosis was successfully treated by stapedectomy for the first time by Shea [1]. He used a prosthesis developed by his friend Harry Treace, which was made of the ''brand-new Teflon material'' [2,3].…”

Stapedotomy with implantation of an alloplastic prosthesis is a well-established therapy for the treatment of otosclerosis. Since the middle of 2008, a new Nitinol prosthesis with memory function and superelastic properties has been available which is expected to make fixation on the long process of the incus much easier. The advantage of this prosthesis is that heat-induced wire crimping is no longer necessary and damage to the incus caused by heat is avoided. Since May 2008, laser-assisted stapedotomy with implantation of a Nitinol prosthesis was performed in 21 patients suffering from otosclerosis. The prostheses used for all patients had a size of 4.5 mm 9 0.4 mm. The patient collective consisted of 14 women and 7 men with a mean age of 53.4 years. Pre-and postoperatively, an ENT examination was carried out followed by an audiological evaluation of the hearing result. In addition, the properties of the prosthesis (''proper fitt'', ''handling'', and ''overall rating'') were evaluated intraoperatively by means of a test protocol. The Nitinol prosthesis was implanted successfully in all 21 patients. The mean air-bone gap for the frequencies from 0.5 to 4 kHz was 9.83 dB postoperatively. Intraoperatively, the fit of the prosthesis was rated as ''good to very good'', the handling as ''good'' and the overall rating of the system was ''good to very good''. Our patient collective showed good postoperative hearing results. Due to simple intraoperative handling, especially placing the Nitinol prosthesis in position, the critical work step of crimping is no longer necessary.

“…Since Shea [11] introduced clinically the procedure of stapedectomy with interposition of a stapes prosthesis in 1958, many different prostheses have become available. At present, the Teflon piston is the most widely employed prosthesis for reconstruction of the ossicular chain in cases of otosclerosis [1].…”

Abstract This study reports the evaluation of hearing results after implantation of a Teflon piston of a different diameter in cases of otosclerosis requiring stapedotomy. By random selection, a Teflon piston with a shaft diameter of 0.3 mm was inserted in 34 cases and a piston with a shaft diameter of 0.4 mm in 26 cases. A retrospective analysis of the pre-and postsurgery audiological results of these two patient groups was carried out by microcomputer. A repeated statistical measures analysis of variance was used to test and estimate the air-conduction frequencyspecific differences between the two prostheses with respect to changes in pre-and postoperative healing. The results of this comparative study of the two Teflon pistons with different diameters indicate statistically a greater hearing gain for the 0.4-mm prosthesis, especially in the lower frequencies.

“…It was first performed by Dr. John J. Shea. 2 Small fenestra or stapedotomy is developed by Shea 1962 in which fenestration is made in footplate of stapes and proper-sized Teflon piston is inserted between the long process of incus and fenestra. This procedure is less traumatic and therefore there are less chances of sensory neural loss.…”
