Summary
Mumps meningoencephalitis significantly increases the risk of sensorineural hearing loss compared to uncomplicated mumps. Audiologic tests reveal higher hearing thresholds in children with mumps meningoencephalitis.
Area of Science:
- Otolaryngology
- Neurology
- Pediatrics
Background:
- Sensorineural hearing loss is a recognized complication of mumps.
- Mumps meningoencephalitis represents a severe form of mumps affecting the central nervous system.
Purpose of the Study:
- To compare hearing thresholds in children with mumps meningoencephalitis, uncomplicated mumps, and healthy controls.
- To determine the specific impact of mumps meningoencephalitis on hearing function.
Main Methods:
- Audiologic tests were conducted on three groups: children with mumps meningoencephalitis (n=26), uncomplicated mumps (n=25), and controls (n=20).
- Hearing level thresholds were measured at speech and high frequencies for both ears.
Main Results:
- Children with mumps meningoencephalitis exhibited significantly higher mean hearing thresholds across various high frequencies compared to uncomplicated mumps cases.
- Mumps meningoencephalitis cases showed elevated hearing thresholds at most frequencies compared to controls.
- Uncomplicated mumps cases also demonstrated higher mean hearing thresholds than controls at specific speech and high frequencies.
Conclusions:
- Mumps meningoencephalitis poses a greater risk for developing sensorineural hearing loss than uncomplicated mumps.
- Early audiological assessment is crucial for children diagnosed with mumps meningoencephalitis.
