[Microbiology of the external auditory canal in patients with asteatosis and itching].
OBJECTIVE
We examined the microbiology of the external auditory canal in patients with asteatosis and itching and evaluated the efficacy of topical 2% alcohol and boric acid solution in patients with normal flora.


METHODS
Bacteriological and mycological cultures were obtained from 76 ears of 45 patients (36 females, 9 males; mean age 41.8 years; range 17 to 66 years) presenting with normal otoscopic findings and no history of ear diseases. Treatment protocols were planned according to the culture results. Patients with normal flora were administered topical 2% alcohol and boric acid solution to relieve itching.


RESULTS
Cultures yielded normal flora in 65 ears (85.5%), bacterial pathogenic flora in 10 ears (13.1%), and mycosis in one ear (1.3%). Complaints of itching decreased significantly following treatment with alcohol and boric acid solution in patients with normal flora (p<0.05). No correlation was detected between age and the severity of itching (p>0.05).


CONCLUSIONS
Despite normal otoscopic findings, external auditory canal cultures may show pathogenic colonization in patients with asteatosis. Topical administration of alcohol and boric acid solution seems to relieve itching in patients with normal flora.
