Summary
Hearing loss is common in Behçet syndrome, often affecting high frequencies. A negative pathergy test was linked to hearing impairment in patients with this condition.
Area of Science:
- Otorhinolaryngology
- Rheumatology
- Genetics
Background:
- Behçet syndrome is a multisystemic inflammatory disorder.
- Audiovestibular involvement is not well-characterized in Behçet syndrome.
Purpose of the Study:
- To determine the prevalence and characteristics of hearing loss in Behçet syndrome patients.
- To investigate potential correlations between hearing loss and clinical findings in Behçet syndrome.
Main Methods:
- Audiological evaluation of 27 Behçet syndrome patients and 35 controls.
- Pure-tone audiometry to assess hearing thresholds.
Main Results:
- Statistically significant hearing loss was observed in the Behçet group compared to controls.
- Sensorineural hearing loss (SNHL) was present in 59.26% of patients, predominantly high-frequency SNHL (93.75%).
- A negative pathergy test correlated significantly with hearing loss in Behçet syndrome patients.
Conclusions:
- Hearing loss is a common manifestation of Behçet syndrome.
- Audiovestibular involvement should be considered in the clinical evaluation of Behçet syndrome.

Unrenewable Cells
In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...

Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
