We evaluated endolymphatic-sac surgery efficacy in 9 subjects for 9 to 30 years (average; 23 years). Due to difficulty in evaluating such surgery, only the 1985 AAO-HNS guideline, which covers 24 months, was used. Endolymphatic-sac surgery was conducted from 1980 to 1990 in 142 subjects with intractable Meniere’s disease, some of whom were treated from 1990 at our clinic.
Results showed that definitive spells were “fairly relieved” in 55%, “relieved” in 45%, but worse in no subjects. Hearing was “improved or unchanged” in 67% but remained “worse” in 33%.
