Tinnitus treatment: an experimental study

Abstract

The objective of the present study was to compare the effectiveness of the selected tinnitus management protocols for the experimental groups, based on the scores obtained for psychosocial variables, quality of life and severity of tinnitus between the four experimental groups following the various treatment protocols. Two-hundred adults ages ranged from 20 to 55 years (mean age 44.14, SD = 6.16) with mild-to-moderate sensorineural hearing loss without tinnitus were randomly selected for the control group, whereas the experimental group comprised 200 adults with mild-to-moderate sensorineural hearing loss with tinnitus without any other associated medical problems. Participants of both control and experimental groups underwent audiological tests and were administered the QoL questionnaire. The experimental group, in addition, was also administered the PSQ, TSI and THI questionnaire and psychoacoustic tests, i.e. measuring pitch, loudness and MML of tinnitus. Participants of experimental group were randomly assigned to 4 groups, each of 50 participants, and treatment was given as below: Group 1: only tinnitus masking sound was administered, Group 2: only counselling was given, Group 3: masking with counselling was given and Group 4: tinnitus masking combined with counselling and attention diversion task therapy was given. The patients without tinnitus had significantly better quality of life in comparison to the patients with tinnitus. Pre-post comparisons of the treatment groups revealed that “masking + counselling + attention diversion task” group showed highly significant differences for psychosocial aspects, QoL and severity of tinnitus. Further, pairwise comparison based on differences in mean scores indicated significant impact of “masking + counselling + attention diversion task” as compared to both in combination like “masking + counselling” or independently, i.e. masking or counselling alone. It appears that an integrated package of intervention (masking + counselling + attention diversion task) might be preferable for providing immediate tinnitus relief by masking through reducing tinnitus loudness and pitch by altering neuroplasticity (tonotopicity); in the long term, it reduces tinnitus impact through positive thinking by counselling treatment and also diverts attention to daily activity through attention training.
