RESUMO
The purpose of this work was to stude the basic audiologic battery as a tool in the retrococler disorder diagnoses. We have tested 21 patients presenting acoustic neurinomam surgically confirmed. The pure tone audiometry has revealed unilateral sensory-neural hearing loss in 20 cases, six of them have had no below 60% in six patients, from l5 who the test was performed the rollover was detected in only half of the patients, what lead us to a 50% of false negative. The tone decay test, performed in eight patients, has revealed retococlear results in only 25%, i.e., a 75% rate of false-negative. At the impedance audiometry in 10 patients, seven have had an absence of responses of the acoustic reflex, and three showed a recruitment. We conclude with these results that the unilateral and/or assimetrical hearing loss in the pure tone audiometry and the absence of the acoustic reflex in the impedance audiometry are the most consistent findings in the basic audiologic attery for a retrococlear disorder
