Purpose
To evaluate nasal mucociliary clearance (NMC) and hearing loss in patients with pseudoexfoliation (PEX) syndrome.
Methods
The study included 36 patients with PEX syndrome as the study group, and 39 healthy individuals as the control group. The duration of NMC was measured using the saccharine test. Audiometry was applied at 250, 500, 1000, 2000, 4000, 6000 and 8000 Hz frequencies to determine hearing thresholds and prevalence of hearing loss.
Results
No statistically significant difference was determined between the groups in respect of age and gender (p = 0.23 and p = 0.36, respectively). In the saccharine test, the mean NMC time was 18.41 ± 8.53 min for the study group and 11.69 ± 4.96 min for the control group. The mean NMC time of study group was significantly longer than that of the controls (p < 0.001).
In the comparisons of the two groups in terms of the prevalence of hearing loss, no statistically significant difference was found at any of the evaluated frequencies (p > 0.05, for all). There was also no statically significant difference between groups in relation to hearing thresholds at these frequencies (p > 0.05, for all).
Conclusion
The NMC time was significantly prolonged in patients with PEX syndrome. This result indicates that nasal mucosa cilia, which have similar elastic and mobile structures as the iris, are damaged in PEX syndrome, which is an infiltrative disease increasing the rigidity of affected tissues. In upper respiratory tract infections of unknown cause, PEX syndrome should be considered among the etiological factors. In this study, no significant relationship was detected between PEX and hearing loss.
