Results
The patients’ average age was 67.9 years (range, 44-83 years). Postoperatively, there were significant improvements in the MPT, MFR, and VHI. Pre- and postoperative comparisons of SFF, PR, and acoustic parameters were not possible in most patients because they had difficulty producing sustained vowel sounds and had a very short MPT.
The mean postoperative SFF and PR were 145.7 Hz (range B2-G3) and 21.7 ± 4.5 semitones (mean ± standard deviation), respectively. The results of the postoperative acoustic analysis of the jitter %, shimmer %, and harmonic-to-noise ratio were 0.53 ± 0.18%, 2.54 ± 1.06%, and 0.12 ± 0.02, respectively. Almost all postoperative test results were in the normal range for elderly adult males. In the postoperative CT neck images, no implant migration, deformation, or fractures were identified.
