This study aimed to evaluate the swallowing and voice functions in patients with ankylosing spondylitis. Thirty patients with ankylosing spondylitis (Group 1) and 30 healthy individuals (Group 2) were included in the study. Following the laryngoscopic evaluation of the patients, the fiberoptic endoscopic evaluation of swallowing was performed, and then, the penetration–aspiration score was determined. The participants were asked to fill the eating assessment tool form. Voice recordings obtained to evaluate sound disorders were measured acoustically and analyzed using the PRAAT program. In terms of swallowing, the penetration–aspiration score obtained as a result of the flexible endoscopic swallowing assessment and eating assessment tool score was found to be higher in Group 1 than in Group 2, and a statistically significant difference was noted (p ≤ 0.001). When analyzing the maximum phonation time (p < 0.001) and fundamental frequency (p = 0.408) values in phonation evaluation, a statistically significant difference was found between the two groups. Group 1 showed a deterioration in terms of jitter (p = 0.040) and shimmer (p = 0.007) compared to Group 2, and a statistically significant difference was noted. There was no statistically significant difference in the harmonic/noise ratio (mean ± standard deviation) between the two groups (p = 0.051). Swallowing and voice functions significantly affect quality of life. Therefore, approaches aimed to improve the associated symptoms have become increasingly important. In patients with ankylosing spondylitis, swallowing quality and phonation ability may be negatively affected. These patients should be monitored for hidden or overt food aspiration.
