Primary Outcome Measures :
  1. Efficacy [ Time Frame: 2 months ]
    Study efficacy evaluations will be based on the analysis of pre and post procedure tinnitus severity characteristics (THI, MML, Pitch matching and VAS values).

Secondary Outcome Measures :
  1. Safety [ Time Frame: 2 months ]
    Safety evaluations will be based on the observation for the reporting of any adverse events occurring during the study and up to the 30 days follow-up visit Occurrence of adverse events.
