Abstract: | A specific group of 28 children (38 ears) with a preexisting sensorineural hearing loss (SNHL) was studied to determine if a perilymphatic fistula (PLF) was the cause of a progression in their hearing loss. A PLF was identified surgically in six of these ears, but there was no evidence of any defect found in 32 ears. The symptoms shared by the cases in which a fistula was found included a traumatic event (including exertion), CT scan evidence of inner ear defects, hearing threshold decreases of 25 to 30 dB, and vertigo or postural instability. |
