Idiopathic Subjective Tinnitus Treated by Amitriptyline Hydrochloride/Biofeedback.
The efficiency of two treatment modalities for subjective/idiopathic tinnitus (SIT): biofeedback (BF) and amitriptyline hydrochloride (AT) was investigated in 225 randomly selected subjects. Findings show that after 10 weeks of treatment in the BF group, 43.5% of the patients reported an improvement of tinnitus during activity. In the AT group, 27.5% of patients reported subjective improvement of tinnitus at rest although only 15.8% of the AT patients reported improvement during activity. Biofeedback during rest had a significantly better effect on tinnitus disturbance than AT. No objective diminishment of tinnitus loudness was found as a result of any of the treatment modalities. We believe that BF can help tinnitus patients especially during periods of rest and we also suggest trying tricyclic antidepressant drugs such as AT for treatment of tinnitus patients, in small doses, however, to minimize the side effects of this drug. Subjective tinnitus (ST) is one of the most common and yet most unclear of otologic symptoms.(1-4) ST can accompany any type of hearing loss including both sensorineural as well as conductive hearing loss, and may originate from any part of the auditory pathway.(1,5) Treatment of ST must be primarily directed to the basic illness diagnosed after a thorough general ear-nose-throat and neurologic evaluation.(6) Severity of ST is evaluated both objectively, by determining the pitch and intensity of the tinnitus,(7) and subjectively as described by the patient. Because of the relatively high incidence of ST and in some patients, the severe personal reaction to it, many different treatments have been suggested, but generally only small to moderate success has been achieved in reducing tinnitus and its consequences, if any at all.(8) In this study we examined the effect of two treatment modalities: amitriptyline hydro-chloride and biofeedback.
