Background and Objectives: There are few studies reported that specifically examine the phonetic characteristics and voice handicap index (VHI) in patients with Allergic Rhinitis. This study was designed to examine phonetic characteristics and VHI in adult patients with allergic rhinitis.
Materials and Methods: Forty-two male patients diagnosed as allergic rhinitis were given skin-prick test and others, aged from 20 to 56 years, and were compared with a 16 male control group with no pathology and in the same age group. The VHI was used to measure the changes of patient’s perception. Acoustic and aerodynamic analysis test were done, and a nasalance test performed to measure rabbit, baby, and mother passage. Acoustic rhionometry (AR) was performed to evaluate nasal volume and nasal crosssectional area. Statistical analysis was done using independent sample t-test.
Results: VHI showed significantly different score in the studied group, higher than that of control group. AR graph showed that there was no significant differences of nasal volume and nasal cross-sectional area. The Shimmer and SFF value in the group of allergic patients were higher than in the control group. MPT value in the group of allergic patients was lower than in the control group. Nasalance in allergic patients showed hypernasality all passage.
Conclusion: We suggest that patients with allergic rhinitis have considerable voice problems. Most of them have hypernasality, which may be a compensatory mechanism by nasal obstruction.
