Summary
The investigators like to learn whether EMLA cream 5% helps tinnitus patients. so far it is
known that lidocaine I. V do helps tinnitus but until now it is not clear if topical
anaesthetics (e. g EMLA cream) helps tinnitus.
The investigators are going to compare 4 days of treatment of EMLA 5% cream Versus (VS.)
cetomacrogol cream (water- based lotion cream) in treating tinnitus patients.
Clinical Details
Official title: EMLA 5% as a Treatment for Tinnitus and Its Accompanied Symptoms
Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Primary outcome: questionnaire results- Beck depression questionnairequestionnaire results- Pittsburgh sleep quality index questionnaire results- tinnitus handicap inventory
Secondary outcome: questionnaire results - Beck depression questionnairequestionnaire results- Pittsburgh sleep quality index questionnaire results- tinnitus handicap inventory
Detailed description:
The purpose of the study is to investigate whether EMLA 5% cream decreases tinnitus by
comparing pretrial questionnaires to post trial questionnaires.
first we are going to invite tinnitus patients for the first visit. in the first visit we
will confirm that the patients is suitable for the trial (no exclusion criteria are present)
, perform ear investigation to exclude ear inflammation, perform audiometry to prove
sensorineural hearing loss. then the patient will fill 3 questionnaires that reflect the
tinnitus severity and show how much the patient does suffer from this conditions. the
questionnaires are- beck depression index, tinnitus handicap inventory, Pittsburgh sleep
quality index.
Then we will perform randomization: the investigational group will get EMLA 5% cream, the
control group will get cetomacrogol cream (a lotion cream).
In the next 4 days the patients (investigational and control groups) will spread the cream
for 4 hours a day in the post auricular area of the ear/ ears that suffer/s from tinnitus.
The patient will be instructed to stop the spreading and call the chief investigator When
any kind of side effect occurs (topical/ systemic)after 4 days of treatment the patient will
come to the clinic once again and fill the same questionnaires. 3 weeks after the beginning
of the trial the patient will fill the questionnaires for the third time.
Regarding the questionnaires:
1. Beck depression questionnaire is a 21-questions exam that checks the depression level
of the patient. The minimum score is 1 the maximum is 63. The investigators hypotheses
states that EMLA cream treatment decreases the Beck questionnaire score
2. Pittsburgh sleep quality index is a 9 questions exam that measure the quality of sleep.
the range of results goes between 0-24. The higher the score- the worse is the quality
of sleep. The investigators hypotheses states that EMLA treatment improves the results
of the Pittsburgh sleep quality questionnaires.
3. Tinnitus handicap inventory estimates the degree that tinnitus affects patients life.
it contains 25 questions . The minimum score is 0 and the maximum is 100 . The
investigators hypotheses that EMLA cream treatment decreases the score of this
questionnaire which means that EMLA cream improves patients quality of life.
