Background and Objectives:
In patients with asthma, increased obstruction and resistance of airway result in impairment in the generation of voice. Allergy and nasal polyposis, which are frequently observed in patients with asthma, are other factors that affect the vocal performance. Bronchodilators and steroids are commonly used in the treatment of asthma, and these agents also have been reported to be associated with voice changes. The aim of this study is to evaluate the voice quality in patients with mild to-moderate asthma by subjective and objective methods.
Materials and Methods:
A total of 36 patients with asthma established in the Department of Respiratory Medicine were included in this study. 23 were women and 13 were men, with a mean age of 51.7 years. The average duration of asthma was 77.0 months. All patients had mild-to moderate asthma. Acoustic and aerodynamic analyses were performed and the movements of the vocal cords were examined by videolaryngostroboscopy (VLS). Voice Handicap Index (VHI) and GRABS scales were used for subjective evaluations.
50% of patients suffered from dysphonia and FO was 119.3${pm}$23.7 Hz in male and 198.2${pm}$18.4 Hz in female patients. There were no significant differences in average shimmer and NHR between females (4.90${pm}$2.95% ; 0.1O${pm}$0.04 dB) and males (4.64${pm}$2.45% ; 0.20${pm}$0.15 dB). However, the value of jitter was greater for females (2.60${pm}$1.92%) than for males (1.21${pm}$0.84%). The VHI score was above the normal limit in 35%, and VLS findings were shown diverse abnormality in 89% asthmatics from mucosal change to hyperfunction of supragottis and contact granuloma. But duration of illness and steroid dose did not correlate with these findings.
Subjective and objective abnormality was shown in more than 50% of asthmatic patients. We suggest that persons who suffer from asthma should be examined for possible voice disorders by laryngologist. Additionally, appropriate medical care and voice therapy should be provided for those who have voice disorders associated with asthma.
