Summary
Chronic otitis media (COM) is associated with sensorineural hearing loss (SNHL), with significant bone conduction threshold differences found. However, disease duration, cholesteatoma, or ossicular erosion did not increase SNHL risk.
Area of Science:
- Otolaryngology
- Audiology
- Neurosurgery
Background:
- Chronic otitis media (COM) is a common condition affecting the middle ear.
- The link between COM and sensorineural hearing loss (SNHL) is debated.
- Understanding this relationship is crucial for effective patient management.
Purpose of the Study:
- To investigate the association between unilateral COM and SNHL.
- To determine if factors like disease duration or cholesteatoma influence SNHL severity.
Main Methods:
- Retrospective study of 41 patients with unilateral COM.
- Comparison of bone conduction thresholds between affected and healthy ears.
- Analysis of correlation between SNHL and disease duration, cholesteatoma, or ossicular erosion.
Main Results:
- Statistically significant differences (P < 0.01) in bone conduction thresholds were observed between diseased and control ears.
- Hearing loss varied from 5.24 to 9.02 dB across frequencies.
- No significant correlation was found between SNHL and disease duration, cholesteatoma, or ossicular erosion.
Conclusions:
- Unilateral COM is associated with a measurable degree of SNHL.
- The severity of SNHL in COM is not significantly influenced by disease duration, cholesteatoma, or ossicular erosion.
