title: Early experience with the Mills sleeve prosthesis for reconstruction of the incus long process.
abstract: This paper describes the Mills sleeve technique of ossicular reconstruction for defects of the incus long process and reviews the results of 27 procedures. A retrospective review of operations was performed by eight otologists. The results are compared with those from three other reconstruction techniques (cortical bone graft, cortical bone sleeve and incus autograft). Prostheses were supplied to surgeons who expressed an interest. Pre- and post-operative audiological data forms were analysed for each case along with a questionnaire about use of the prosthesis. The mean post-operative air bone gap (ABG) was compared with results from cortical bone sleeve, incus autograft and simple cortical bone graft reconstruction cases previously performed by the senior author. Twenty-seven procedures were performed. Closure of the ABG to within 10 dB was achieved for 44.4 per cent of Mills sleeve cases compared with 44.7 per cent for the cortical bone sleeve, 52.9 per cent for ossicular and 26.9 per cent for cortical bone grafts. The responses to a questionnaire sent to participating surgeons are discussed. For the current follow-up period (three months to three years) the Mills sleeve prosthesis appears to be safe and easy to use with audiological results at least as good as other reconstructive techniques.
