Abstract

Objective: To evaluate olfactory functions in patients with laryngopharyngeal reflux.


Methods: The
study consisted of control and reflux groups. Each group consisted of 50
patients. Reflux group received the diagnosis of reflux based on reflux
symptom index, and reflux symptom scores. The olfactory test of
Connecticut Chemosensory Clinical Research Center (CCCRC) was conducted
on these 2 groups, and the results were compared.


Results: No
statistically significant difference was found between the demographic
characteristics such as gender and smoking rates while there was
statistically significant difference between the groups in terms of age
variable. The covariance analysis was used to eliminate the effect of
age variable. The mean scores calculated after covariance analysis were
compared. It is known that the higher score of CCCRC test is 7 points.
Accordingly, CCCRC scores of the control and reflux groups were 5.84±
0.13, and 5.20±0.11, respectively. This difference between two groups
was statistically significant (p<0.001).


Conclusion: Laryngopharyngeal reflux disease has a negative effect on olfactory functions without total loss in olfactory functions.
