Treatment of tinnitus with a customized, dynamic acoustic neural stimulus: clinical outcomes in general private practice.Ann Otol Rhinol Laryngol. 2008 Nov; 117(11):791-9.AO
We evaluate the relative effectiveness of a newly available tinnitus treatment approach for different categories of patients in general private practice.
This was a cohort study, sponsored by Neuromonics, involving the first 470 patients to undertake the Neuromonics Tinnitus Treatment in 7 Neuromonics tinnitus clinics. All patients were provided with a dynamic acoustic neural stimulus, customized to each patient's audiometric profile, for daily use as part of a structured rehabilitation program. Tinnitus disturbance was assessed before, during, and after treatment with the Tinnitus Reaction Questionnaire.
The outcomes displayed a relation with patients' suitability according to predefined criteria: among the most suitable patients (tier 1 cohort), 92% exceeded the threshold for success (defined as a reduction in tinnitus-related disturbance of at least 40%), and the mean improvement in tinnitus disturbance was 72%; the discontinuance rate was 4%. For other suitability categories, the success rates and mean improvements were somewhat lower, and the discontinuance rates higher (tier 2: 60%, 49%, and 16%, respectively; tier 3: 39%, 32%, and 17%, respectively).
The results showed that the treatment is effective for suitable patients in the private practice setting, and they provide health-care professionals with guidance as to what patients might expect from treatment, depending on their degree of suitability.
