OBJECTIVE: Comparison of the sensitivity of Sp/Ap amplitude and area ratio in the aid of diagnosis of Meniere's disease. Meniere's disease was defined by the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium.
METHOD: The study sample consisted of 35 patients in our hospital, who were undergone tympanic electrocochleography (EcochG). A control group of 10 patients (20 ears) with normal Sp/Ap ratio and EcochG data were identified. Sp/Ap amplitude and area curve ratios for both group were measured.
RESULT: The traditional upper limit and the upper limit of normal for Sp/Ap amplitude and area curve were respectively 0.4, 46 and 1.94. Of 35 patients with Meniere's disease, had an abnormal Sp/Ap amplitude ratio,and had an abnormal Sp/Ap area curve ratio; the difference between groups was statistically significant.
CONCLUSION: Sp/Ap curve area curve ratio is more sensitive than conventional Sp/Ap amplitude ratios in diagnosis of Meniere's disease.
