Özet
Objective: This study aimed to compare cervical vestibular evoked myogenic potentials (cVEMP) elicited by tone burst (TB) and narrow band level-specific chirp (NB LS-CE Chirp) stimuli at 500, 1, 000, 2, 000, and 4, 000 Hz in healthy individuals. Methods: Thirty-two healthy participants (15 females, 17 males; mean age: 24.59 ± 1.93 years) underwent otoscopic examination, pure-tone audiometry, and cVEMP testing at 95 dB nHL using TB and NB LS-CE Chirp stimuli. P1 latency, N1 latency, and P1N1 amplitude were recorded. Results: At 500 Hz, both stimuli elicited responses in all subjects. Significant differences in P1 latency, N1 latency, and P1N1 amplitude were found between the stimuli at 500 and 1, 000 Hz (p < 0.05). No significant differences were observed at 2, 000 and 4, 000 Hz (p > 0.05). Conclusion: NB LS-CE Chirp stimuli generate larger and earlier cVEMP responses than TB stimuli, particularly at lower frequencies, suggesting higher effectiveness for saccular assessment.
