Phonosurgery of vocal fold polyps, cysts and nodules is beneficial.

INTRODUCTION

This study reports our experience with microscopic phonosurgery (PS) of benign lesions of the vocal folds.

MATERIAL AND METHODS

During the five-year period from 2003 to 2007, a total of 97 patients had PS for vocal fold polyps (n = 63), vocal fold cysts (n = 17), vocal fold nodules (n = 12) or vocal fold oedema (n = 5). Their average age was 41 years; 62% were women and 69% were smokers. Post-operative voice therapy was given to 45 patients. Post-operative clinical evaluation was available for data analysis in 89 patients (92%). Voice quality was assessed using the Multi-Dimensional Voice Program (MDVP), video-stroboscopy and self-reported assessment. The median follow-up time was 3.9 months.

RESULTS

Post-operative voice quality was reported as unaffected in 85%, improved but moderately affected in 13%, and severely affected in one patient with a cyst and vocal fold sulcus. Unaffected voice quality was obtained in 91% of patients not receiving voice therapy and in 77% of patients receiving voice therapy. All lesions except one polyp in the anterior commissure were completely removed. MDVP was performed both pre- and post-operatively in 22% of patients. The effect was a significant improvement of jitter (p = 0.013), shimmer (p = 0.001) and Soft Phonation Index (p = 0.013).

CONCLUSION

PS is a quick and effective treatment with uncommon and transient post-operative complications. Objective assessment of the voice pre- and post-operatively should be used consistently and applied in controlled studies evaluating the additional impact of pre- and post-operative voice therapy.
