Abstract
- Since the characteristics of aminoglycoside ototoxicity is typically bilaterally symmetric progression of cochlea-vestibular dysfunction, a unilateral involvement has rarely been reported. However, ototoxicity can be asymmetric or focal after systemic aminoglycoside treatment. The authors report 2 cases of asymmetric or focal audiovestibular deficits in patients treated with systemic aminoglycoside. In such cases, further investigations are also necessary to rule out other possible causes of unilateral sensorineural hearing loss such as cerebellopontine angle tumors.
