- Abstract
Objectives: To compare the audiological and non-audiological benefits of incus short process (SP) vibroplasty with those of conventional incus long process (LP) vibroplasty. Methods: Retrospective chart reviews were performed. Thirty- six patients with sensorineural hearing loss were treated with a middle ear implant (Vibrant Soundbridge®). Of these, 22 were treated with conventional LP vibroplasty, and 14 were treated with SP vibroplasty using SP couplers. All surgical procedures were performed by a single surgeon. Patients underwent pure-tone/free-field audiography and word recognition tests before and 3 months after the surgery. Operation time and duration of hospital stay were obtained through chart reviews, and a questionnaire was used to assess postoperative complications. The results of these tests were compared. Results: The improvement in hearing gain was comparable between SP vibroplasty and conventional LP vibroplasty, except at 8 kHz (P < 0.05). Patients undergoing SP vibroplasty had shorter operation time (P < 0.01) and duration of hospital stay (P < 0.01). While four patients who underwent incus LP vibroplasty experienced taste changes, none who underwent incus SP vibroplasty experienced any complications. Conclusions: SP vibroplasty with the newly invented SP coupler could be a good alternative to conventional LP vibroplasty for treating patients with sensorineural hearing loss. Although both SP vibroplasty and LP vibroplasty produce good results, the former is associated with a shorter operation time and duration of hospital stay as well as fewer complications.
