Evaluation of Vocal Efficiency for the Polyps and Nodules

Abstract
|
|
|
The vocal efficiency(VE) can be calculated as the ratio of acoustic power to aerodynamic power. It relates to the vocal intensity, air flow rate and subglottic pressure. In this study, we treated 20 cases of vocal polyps and 10 cases of vocal
nodules by
way of laryngo-microsurgery or laser laser laryngo-microsurgery. The VE was measured preoperatively and postoperatively in all cases. The results showed that there was significant improvement of VE postoperatively than that of preoperative
measurement(p<0.01) in vocal polyp group. However, there was no significant difference(P>0.05) in vocal nodule group. Through comparing the results, we obtained the conclusion : The laryngo-microsurgery is the reliable method of management for
the
vocal
polyps, but for the vocal nodules, the laryngo-microsurgery should be selected after other more conservative approaches fail to produce the desired results.
