Abstract
The 1972 AAOO committee (Alford, 1972) guidelines brought some uniformity into the evaluation of therapy for Meniere's Disease. We have adhered to its recommendations in this long-term follow-up report of 21 saccus decompressions and 29 vestibular nerve sections performed on 46 patients between 1968 and 1977. Comparisons between these and other groups have been possible with regard to: 1. control of vertigo; 2. hearing; 3. tinnitus; and 4. development of hydrops in the contralateral ear. All the vestibular nerve section group have enjoyed sustained relief from vertigo. Class D results (recurrent vertigo) account for 14 per cent of the saccus decompression group at one year and 29 per cent at eight to 10-year follow-up. Hearing levels in both groups deteriorated in parallel as time progressed but tinnitus became less noticeable. Nineteen per cent of the long-term review patients showed evidence of developing cochlear hydrops in the contralateral ear. Conservative surgical procedures should be employed whilst any useful hearing exists, though the emphasis remains on controlling vertigo. Saccus decompression, despite its controversial therapeutic basis, will remain the first-line surgical procedure for many otologists. However, in the fit young Meniere's cripple or saccus decompression failure with serviceable hearing, vestibular nerve section remains the treatment of choice.
