摘要

Objective

To investigate the potential interaction between the vestibular and olfactory systems by evaluating olfactory identification performance in patients with BPPV.

Methods

Fifty-two patients with BPPV and 50 age-matched healthy controls were evaluated using the 16-item Sniffin’ Sticks identification test Hummel et al. (Chem Senses. 22(1):39-52, 1997). The control group was derived from a standardized institutional database with specific age-matching protocols to ensure transparency across departmental research Kar et al. (Eur Arch Otorhinolaryngol, 2026).

Results

The Mean Total Olfactory Score was lower in the BPPV group (10.92 ± 2.13) compared to controls (11.66 ± 2.01); however, this difference did not reach statistical significance (p = 0.0805). Significant differences were observed for specific odors, notably “Orange” (p = 0.016).

Conclusion

BPPV appears to have a marginal, sub-clinical impact on olfactory identification. The transient nature of paroxysmal vestibular stimulation may be insufficient to cause the robust sensory reorganization seen in chronic vestibular pathologies.
