Pseudomonas labyrinthitis
Abstract:
Pseudomonas aeruginosa is the gram-negative bacterial rod which is often isolated from chronic aural discharge. This microorganism may also cause necrotizing infection of the external auditory canal in certain patients with impaired host-defense mechanisms. Involvement of the inner ear by this microbe is extremely rare. In this communication, we report a case of pseudomonas labyrinthitis which resulted from traumatic middle ear injury. Infection produced massive granulations and extensive bone destruction of the otic capsule. This case shows that while P.aeruginosa is usually an avirulent opportunistic pathogen, it may also cause a highly destructive labyrinthitis if the inner ear is entered.
Insights
Pseudomonas aeruginosa can cause severe infections. This study details a rare case of destructive pseudomonas labyrinthitis following a traumatic middle ear injury, highlighting its potential virulence.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Microbiology
Background:
- Pseudomonas aeruginosa is a gram-negative bacterium frequently found in chronic ear infections.
- Necrotizing infections of the external auditory canal by P. aeruginosa occur in immunocompromised individuals.
- Inner ear involvement by P. aeruginosa is exceptionally rare.
