Vokal kord poliplerinde cerrahi tedavi sonrası ses kalitesinin değerlendirilmesi

Abstract

Objective: Endolaryngeal microsurgery is the fundamental treatment of vocal cord polyps. After surgical treatment, the changes in the voice quality can be measured by various scales that examine the audio perception of the voice and/or by objective voice analyses done with the help of a software program. The aim of this study was to evaluate the vocal performance of the patients with vocal cord polyps operated with endolaryngeal microsurgery. Methods: In this study, Vocal Performance Questionnaire and acoustic voice analyses were performed on 40 patients with vocal cord polyps operated with endolaryngeal microsurgery and the results were compared statistically. Results: When pre-, and postoperative comparisons of the parametres of the cases were evaluated statistically by Vocal Assessment program, a statistically significant decrease in postoperative Jitter (%), Shimmer (%), Fo tremor (Hz), noise energy (dB), harsh voice, hoarse voice, breathy voice parameters, while a statistically significant increase in percent voiceless, and voiced time during habitual phonation, fundamental frequency change interval (Hz) was detected. However in statistical comparisons of parameters using Real Analysis Program, a statistically significant decreases were detected in percent voiceless time during habitual phonation, fundamental frequency change interval (Hz), and percent voiceless time values between the lowest-, and the highest-pitched sounds that could be recorded during phonation after the treatment, while statistically significant increases in posttreatment percent voiced time during habitual phonation, percent voiced time values between the lowest-, and the highest-pitched sounds that could be recorded during phonation, and fundamental frequency change interval (Hz) were demonstrated. Conclusion: It has been conceived that the physiology of the larynx can be protected with a successful surgical excision and the phonatuary functions of the vocal cords can be returned to normal.
