[Microbiological and auditory analysis before and after topical treatment of chronic suppurative otitis media without cholesteatoma]. / Análisis microbiológico y auditivo antes y después del tratamiento tópico en otitis medias crónicas supurativas no colesteatomatosas.

ABSTRACT

The AA. present a study microbiologic and auditive as well about chronic, suppurative otitis media non cholesteatomatous, before and after topical treatment. They contemplate 178 samples of chronic discharging ears which were treated with gentamycin 0.3 %, instillation 5 drops every 8 hours, during 10 days. Twelve days later were newly assessed both the otorrhea and the cochleovestibular picture. Germs most frequently detected Gram-negative 61.6 %, Gram-positive 19.8 %, associated flora 6.4 % and mycosis 2.2 %, among other. Clinic healing accounted for 97.29 % and not significative differences scored pre--and post-treatment.
