Relationship between the degree of cochlear endolymphatic hydrops and disease staging

Meniere disease staging was obtained by calculating the pure tone average hearing thresholds at 500, 1000, 2000, and 3000 Hz (Committee on Hearing and Equilibrium, American Academy of Otolaryngology-Head and Neck Foundation. Committee on Hearing and Equilibrium guidelines for the diagnosis and evaluation of therapy in Menière's disease. American Academy of Otolaryngology-Head and Neck Foundation, Inc. Otolaryngol Head Neck Surg 1995;113[3]:181-5). Both ears were evaluated separately for patients with bilateral Meniere disease. The average hearing thresholds for stages 1, 2, 3, and 4 were 25 or lower, 26 to 40, 41 to 70, and higher than 70 dB HL, respectively. (Source: Huang Y, Zhao P, Han Z, et al.
