Comparison of Acoustic and Stroboscopic Findings and Voice Handicap Index between Allergic Rhinitis Patients and Controls.

BACKGROUND

In our experience Allergic Rhinitis (AR) patients suffer from voice problems more than health subjects.

AIMS: To investigate the acoustic analysis of voice, stroscopic findings of larynx and Voice Handicap Index scores in allergic rhinitis patients compared with healthy controls.

STUDY

DESIGN

Case-control study.

METHODS

Thirty adult patients diagnosed with perennial allergic rhinitis were compared with 30 age- and sex-matched healthy controls without allergy. All assessments were performed in the speech physiology laboratory and the testing sequence was as follows: 1. Voice Handicap Index (VHI) questionnaire, 2. Laryngovideostroboscopy, 3. Acoustic analyses.

RESULTS

No difference was observed between the allergic rhinitis and control groups regarding mean Maximum Phonation Time (MPT) values, Fo values, and stroboscopic assessment (p>0.05). On the other hand, mean VHI score (p=0.001) and s/z ratio (p=0.011) were significantly higher in the allergic rhinitis group than in controls.

CONCLUSION

Our findings suggest that the presence of allergies could have effects on laryngeal dysfunction and voice-related quality of life.
