Malignant external otitis: management policy
1Department of Otolaryngology, Riyadh National Hospital, Saudi Arabia.
Abstract:
Malignant external otitis is a progressive pseudomonal infection of the external auditory canal and adjacent structures. In the literature there is no unified policy regarding the management of malignant external otitis. The development of an effective nuclear scanning method and antibiotics active against Pseudomonas aeruginosa have helped in formulating our management policy. A review of four years personal experience with this condition is presented. All of our cases were cured from the disease with no fatality. Gallium citrate scans showed that antipseudomonal treatment should continue for up to three months.
Insights
Malignant external otitis, a serious Pseudomonas aeruginosa infection, requires a unified management approach. Effective nuclear scans and targeted antibiotics led to successful treatment in all cases, with treatment continuing for three months.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Nuclear Medicine
Background:
- Malignant external otitis is a severe pseudomonal infection affecting the ear canal and surrounding tissues.
- Current literature lacks a standardized management protocol for this condition.
- Pseudomonas aeruginosa is the primary causative pathogen.
Purpose of the Study:
- To present a management policy for malignant external otitis based on personal experience.
- To evaluate the efficacy of nuclear scanning and targeted antibiotic therapy.
- To establish optimal treatment duration for antipseudomonal therapy.
Main Methods:
- Review of a four-year personal experience with malignant external otitis cases.
- Utilized Gallium citrate scans for disease monitoring and treatment guidance.
- Administered antibiotics specifically targeting Pseudomonas aeruginosa.
Main Results:
- All documented cases of malignant external otitis were successfully cured.
- No fatalities were recorded among the treated patients.
- Gallium citrate scans indicated that antipseudomonal treatment should extend up to three months.
Conclusions:
- A unified management policy incorporating nuclear imaging and targeted antibiotics is effective.
- Early diagnosis and consistent treatment are crucial for favorable outcomes.
- Prolonged antipseudomonal therapy, guided by Gallium citrate scans, ensures complete eradication of infection.
