ABSTRACT

Background: Benign lesions of the vocal cords are a common cause of dysphonia. The Voice Handicap Index (VHI) quantifies the impact perceived by an affected subject in emotional, physical and functional aspects of voice disorders. VHI provides a numeric value and classified dysphonia as mild, moderate, severe and serious.
Objective: To describe the degree of pre- and postoperative dysphonia by Voice Handicap Index in its abbreviated version (VHI-10).
Patients and method: A clinical, descriptive, prospective and longitudinal study was performed including 36 adult patients with benign larynx lesions such as polyp, nodule, cyst and papiloma from June to December 2010, which met the criteria for inclusion under informed consent. We applied the VHI-10 questionnaire. The sample size calculation was performed using the formula to observe the group average difference pre- and postsurgery using Epicalc 2000 program; Student t test was applied.
Results: The preoperative Voice Handicap Index value was 25.72 (severe dysphonia) and the postoperative value was of 8.4 (mild dysphonia). Clinical relevance was found in 86.1% of cases (31 patients) The overall significance was statistically significant at p = 0.000.
Conclusions: The VHI-10 is a reliable, simple and validated tool to assess subjective changes in dysphonia in patients with benign larynx disease.
