Resonance Effect of the Frontal Sinus on Ocular Vestibular-Evoked Myogenic Potential Recordings

Conclusions: Both developmental (frontal sinus volume) and pathological (frontal sinus inflammation) factors may affect the oVEMP responses via altering resonance function. For the developmental factor, frontal sinus volume>1.91 mL may initiate the resonance effect on oVEMPs, as evidenced by higher response rate with larger reflex amplitude of Fpz-oVEMP than Fz-oVEMP. For the pathological factor, frontal sinusitis may hamper the resonance effect on oVEMPs, as shown by the lower response rate of Fpz-oVEMP than Fz-oVEMP. Hence, oVEMP test may be performed via Fpz bone vibration first in healthy adults, while via Fz bone vibration first in children aged under 14 years or subjects with frontal sinusitis.
