Relationship between long-lasting suppression of plasma stress hormone vasopressin and good results in endolymphatic sac drainage surgery. One hundred patients with intractable Meniere's disease received endolymphatic sac drainage surgery were divided into the complete group (n = 48: zero vertigo and more than 10 dB improvement) and non-complete group (n = 52: others). The cases with good surgical results in vertigo and hearing at the 2nd post-operative year showed significantly lower levels of plasma vasopressin (pAVP) at least for 2 years predictively. *Significant (p < 0.05); NS, not significant.
