IWayan Marthana Kedel, Edhie Samodra, Bambang Udji Djoko Rianto -The effectiveness of rivanol tampon" compared
with burowi tampon in acute diffuse otitis externa (ADOE)patients
Background: Acute diffuse otitis externa (ADOE) is one of the common diseases in ENT Department, Dr. Sardjito
Hospital, with the frequency of 9-1 2%. The most common microorganism found is Pseudomonas aeruginosa. Infection
usually occurrs after taking a bath, washing hair, and scratching the external ear canal. Treatment of acute diffuse
otitis externa which consists of topical preparations, Le. antibiotics and antiinflammation tampon or ear drop, is
relatively expensive. A rationale, high recovery rate, cheap, and easily found preparation is needed. Burowi solution
is one of the recommended treatment, but it is less popular.
Objective: The goal of this study was to know the effectiveness of Rivanol" tampon compared with Burowi tampon
in acute diffuse otitis externa.
Methods: A randomized single-blind controlled trial (RCT)was performed at the outpatient clinicof ENTDepartment
of DrSardjito General Hospital, Yogyakarta. Sixty-five subjects who were'diagnosed as ADOEwho met inclusion
criteria were randomly allocated into two groups, that is, Rivanol"group and Burowi group. The ear canal was
cleaned, and then Rivanol"tampon or Burowi tampon was applied. Evaluation was performed on day 3 and 5.
Primary outcome was the recovery rate, and secondary outcomes were adverse reaction and marginal costeffectiveness.
Results: Of 65 subjects, 33 were alloc'8ted into Rivanol"group and 32 were. allocated into Burowi group. The
recovery rate in Rivanol"group was 75.4%, while in Burowigroups was 49.3%. The difference in recovery rate
between the two groups was statistically significant (p: 0.018
