Abstract:
Diabetes Mellitus (DM) is a metabolic disease characterized by chronic hyperglycemia.
Chronic hyperglycemia causes long-term dysfunctions of various body systems. The main
objective of the present study is to investigate swallowing and voice functions of diabetic
patients. 121 diabetic patients with a mean age of 53,11±9,90 years and 40 healthy
volunteers with a mean age of 50,23±5,42 years were recruited for this study. For each
participant, T-EAT-10 questionnaire was completed and a Fiberoptic Endoscopic
Evaluation of Swallowing (FEES) was planned for each individual who had a risky score
according to the questionnaire (score≥3). In addition, acoustic and aerodynamic voice
evaluation were performed to all participants. Praat program was used for acoustic voice
analysis. As a result of the swallowing questionnaire 22,3% of the diabetic subjects were in
the risky group while nobody was at risk in the control group. FEES showed us, 95% of
the diabetic patients had a safe swallowing function according to the PAS score and
neuropathy did not have a direct effect on oropharyngeal swallowing. However, decreased
laryngeal sensation, increased secretion and presence of residue revealed that diabetic
patients with swallowing complaint have reduced swallowing efficiency. On the other
hand, 9,9% of diabetic individuals reported voice problems. The voice evaluation revealed
that the duration of diabetes and the level of glycemic control did not have any effect on
voice parameters but neuropathy affects both aerodynamic and acoustic voice parameters.
Based on these results, this study has clearly shown that diabetic individuals may
experience various swallowing and voice related problems.
