[The voice analysis of subtotal laryngectomy by pedicled flaps reconstruction of vocal cord].
OBJECTIVE
To compare the voice quality of patient's after surgery over one year between the reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps and other laryngeal function in subtotal laryngectomy.


METHODS
By using Dr Speech's acoustic analysis software, the noise level of the testing room was controlled under 45 dB. Before testing, patients have pronounced training. The testing voice was selected as[ae]. The evaluation parameters were jitter, shimmer, and NNE.


RESULTS
All the acoustic parameters of the reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps were increased distinctly than normal. There were statistical significant differences; compared with those by subtotal laryngectomy, the parameters decreased distinctly, and the voice quality improved distinctly.


CONCLUSIONS
The reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps improve the voice quality, the acoustic analysis can be a measurable data of the postoperative voice quality evaluation, and administer to its objective evaluation.
