Malignant external otitis in children
Insights
Malignant external otitis, a Pseudomonas aeruginosa infection, affects immunocompromised children, causing severe ear pain and potential bone destruction. Early diagnosis and anti-Pseudomonas treatment are crucial to prevent complications like facial nerve paralysis.
Area of Science:
- Pediatric Infectious Diseases
- Otolaryngology
- Microbiology
Background:
- Malignant external otitis (MEO) predominantly affects immunocompromised pediatric patients.
- It is characterized by Pseudomonas aeruginosa infection, severe otalgia, otorrhea, elevated erythrocyte sedimentation rate, and bone destruction on CT scans.
Purpose of the Study:
- To review the clinical presentation and management of MEO in children.
- To highlight the emerging nature of this infection in the pediatric population and emphasize the need for prompt diagnosis and treatment.
Main Methods:
- Literature review of MEO cases in children.
- Analysis of clinical features, diagnostic criteria, and treatment outcomes.
Main Results:
- Pediatric MEO cases show higher incidence of seventh nerve paralysis and middle ear involvement compared to adults.
- A significant increase in reported cases since 1980 suggests an emerging trend.
- Prompt diagnosis and early anti-Pseudomonas therapy are associated with reduced morbidity.
Conclusions:
- Malignant external otitis is an increasingly recognized, treatable infection in children.
- Pediatricians must be aware of the distinct clinical manifestations and the urgency of initiating appropriate therapy.
- Early intervention can significantly alleviate patient morbidity.
Abstract:
Malignant external otitis in the pediatric population is primarily a disease of children with chronic illness or immunosuppression. The presence of severe, unrelenting otalgia, otorrhea with isolation of Pseudomonas aeruginosa, a markedly elevated erythrocyte sedimentation rate, and evidence of bone destruction on computed tomography scan should alert the clinician to the diagnosis. Unlike adults, children have a higher incidence of seventh nerve paralysis earlier in the course of the infection. They also manifest more frequent involvement of the middle ear with tympanic membrane destruction. The short interval between the onset of symptoms and facial nerve dysfunction highlights the necessity of prompt diagnosis and institution of anti-Pseudomonas therapy. Our review suggests that this destructive bacterial infection is an emerging clinical entity in children; 73% of the cases have been reported since 1980. Pediatricians should therefore be familiar with the clinical presentation of this treatable infection. Substantial morbidity could be alleviated by prompt diagnosis and early antibiotic treatment.
