K. Mizukoshi et al., PRELIMINARY GUIDELINES FOR REPORTING TREATMENT RESULTS IN MENIERES-DISEASE CONDUCTED BY THE COMMITTEE OF THE JAPANESE-SOCIETY-FOR-EQUILIBRIUM-RESEARCH, 1993, Acta oto-laryngologica, 1995, pp. 211-215
In order to draft guidelines for reporting treatment results in Menier
e's disease (MD) in Japan, 17 committee members elected from the Japan
ese Society for Equilibrium Research (JSER) have met for about two yea
rs. The preliminary guidelines obtained from their discussions are sum
marized as follows. i) Evaluations of symptoms: Only definitive vertig
inous spells with spontaneous nystagmus should be evaluated (AAOO, 197
2). The parameter for the assessment of hearing levels should be evalu
ated using four-frequency pure-tone averages (PTA) at 250 Hz, 500 Hz,
1 kHz and 2 kHz. ii) Evaluation period: Valid results for the evaluati
on should be based on observations at least six months before treatmen
t and over at least 12 months after initiation of therapy. iii) Evalua
tion criteria The formula expressing the effects of treatment on verti
ginous spells should adopt a numeric vertigo score, which is shown in
the AAO-HNS (1985) guidelines. If the duration of pre-treatment evalua
tion period is less than 6 months, the divisor is replaced by the aver
age of definitive spells per month for the period of observation. iv)
Global judgment: For a global judgment, patients and doctors should jo
intly evaluate the treatment results from the standpoints of their sub
jective and objective symptoms respectively.
