Malignant otitis externa (MOE) patients with cranial nerve involvement or temporal bone erosion face prolonged treatment and poorer outcomes. Early, aggressive therapy is crucial for preventing complications.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Oncology
Background:
- Malignant otitis externa (MOE) is an aggressive infection of the external ear canal.
- MOE can invade the temporal bone, leading to severe complications.
Purpose of the Study:
- To investigate the relationship between clinical features and treatment outcomes in MOE patients.
- To identify factors predicting prolonged treatment and disease recurrence.
Main Methods:
- Retrospective descriptive study analyzing patient data from 2008-2018.
- Evaluation of 30 patients diagnosed with malignant otitis externa.
Main Results:
- Diabetes mellitus was the most common comorbidity (76%).
- Pseudomonas aeruginosa was the most frequent pathogen (47%).
- Facial nerve palsy and temporal bone erosion correlated with longer treatment durations and higher recurrence rates.
Conclusions:
- Cranial nerve involvement, temporal bone erosion, and comorbidities are associated with prolonged treatment and adverse prognosis.
- Prompt diagnosis and aggressive treatment are vital for improved outcomes in MOE patients.
