Hair-clip type piston artificial stapes and the safety auger

A hair-clip artificial stapes prosthesis was used in the surgical treatment of otosclerosis in 22 ears. In nine patients followed an average of 15 months the air-bone gap stabilized at 6-7 dB. Further advantages of the prosthesis design and technique are that they minimize the risk of ischemic necrosis and perilymphatic fistula formation.
