Abstract: The aim of the study is to describe the vocal characteristics of a group of female patients with goiter. For this purpose, a total of 43 female patients with goiter presenting to the endocrinology clinic and another age-matched group of controls were recruited. Patients underwent acoustic analysis and perceptual evaluation of their voice using the GRABS classification. Zero was considered normal, and 1, 2 and 3 as mild, moderate, severe deviation from normal, respectively. The mean score of each parameter was computed and the distribution of severity of each perceptual parameter was listed. The results of the study showed no significant difference in any of the acoustic variables between patients and controls. There was also no significant difference in the mean score of any of the perceptual evaluation parameters between the two groups except for straining. Goiterous patients had a significantly higher straining score comparing to controls, 0.48±0.59 vs. 0.13 ±0.35, with a p value of 0.039. The means of all the perceptual parameters were less than 1 indicating a relatively mild or minimal deviation from normal. Therefore, female patients with goiter seen in a clinical set up have more vocal straining compared to controls, however, the amount of straining is minimal. Acoustic analysis failed to reveal any significant difference compared to controls.
