CLINICAL COMPLICATIONS OF MALIGNANT OTITIS EXTERNA AND SURGICAL TREATMENT

Resumo

For clinical complications of malignant otitis externa and its surgical treatment, the introduction addresses a rare and serious condition, characterized by necrotizing infection of the external auditory canal, often associated with comorbidities such as decompensated diabetes mellitus. This condition requires rapid intervention due to the potential for spread to adjacent structures such as the skull and skull base, resulting in serious complications such as facial paralysis, osteomyelitis, and meningitis. Management includes broad-spectrum intravenous antibiotic therapy and, in many cases, surgical intervention to debride necrotic tissue and control infection. Objective: to synthesize recent evidence on the effectiveness of surgical treatments in malignant otitis externa, highlighting clinical outcomes and associated mortality. Methodology: it was structured according to the PRISMA checklist, using PubMed, Scielo and Web of Science databases to search for articles published in the last 10 years. Descriptors included "malignant otitis externa", "surgical treatment", "complications", "mortality" and "intervention". Inclusion criteria were clinical studies and systematic reviews that addressed surgical treatment and clinical outcomes. Exclusion criteria were studies focusing exclusively on non-surgical treatments, isolated case reports and studies with fewer than 10 participants. Results: highlighted the effectiveness of early surgical debridement in reducing mortality and serious neurological complications. The analysis revealed that adjuvant antibiotic therapy and intensive surveillance are crucial for successful management. Conclusion: the importance of a multidisciplinary approach and timely surgical intervention is emphasized to improve outcomes in patients with malignant otitis externa, highlighting the need for further studies to elucidate ideal therapeutic protocols and prevention strategies
