Chapter: Aging
Chapter section: Atrophy of Stria Vascularis
TB Case Number: 1024
Comments: 94 yr old female with genetically determined, adult onset, sensorineural hearing loss due to stria vascularis atrophy. Her mother had a similar hearing loss. The patient began to lose hearing in her 30s. The audiometric pattern was that of a flat, progres
