Comparison of effects on voice of diode laser and cold knife microlaryngology techniques for vocal fold polyps.
J Voice. 2014 May; 28(3):387-92.JV

Abstract

AIM

To compare the effects on voice of endolaryngeal microsurgery (EMS) with cold instruments and a new method, "diode laser," for vocal fold polyps.

PATIENTS AND METHODS

Fifty-one patients with vocal fold polyps suffering from dysphonia who were treated in the Erciyes University Department of Otolaryngology were included in the study. Voice analysis was performed in a soundproof room, holding the microphone 15 cm away from the patients' mouth and by recording a sustained [a] vowel for at least 10 seconds. Fundamental frequency (F0), Jitter, Shimmer, and noise-to-harmonic ratio (NHR) parameters were evaluated in terms of vocal analysis. All patients were asked for to fill in a questionnaire, after being informed about the voice handicap index (VHI). EMS was performed with a diode laser and cold knife on 26 and 25 patients, respectively. Patient follow-up was performed 8 weeks after surgery. Changes in F0, Jitter, Shimmer, and NHR values were measured and recorded. VHI was also completed and reassessed.

RESULTS

There was a significant difference in each technique's VHI score between the preoperative and postoperative questionnaire (P < 0.001). Postoperatively, there was no significant difference in VHI scores between two groups (P > 0.05). There was a significant difference in voice analysis values measured preoperatively and at the postoperative controls for both groups (P < 0.05). Postoperatively, there was no significant difference in voice analysis values between two groups (P > 0.05).

CONCLUSION

In the treatment of vocal polyps, EMS with both diode laser and traditional cold knife is effective.
