[Rational treatment of necrotizing external otitis]

Area of Science:

• Otolaryngology
• Infectious Diseases
• Hyperbaric Medicine

Background:

• Necrotizing external otitis (NEO) is a severe infection of the ear canal.
• Historically, NEO presented a poor prognosis, often termed 'malignant' otitis externa.
• Recent advancements have transformed the understanding and management of this condition.

Observation:

• Hyperbaric oxygen therapy (HBOT) significantly enhances the efficacy of modern antibiotics.
• Radioisotope examination of petrous bones aids in diagnosis and determining treatment duration.
• Medical management is the primary therapeutic approach, with surgery reserved for refractory cases.

Findings:

• The combination of HBOT and potent antibiotics has dramatically improved NEO prognosis.
• Diagnostic tools like radioisotope imaging allow for precise monitoring and treatment endpoint determination.
• NEO is no longer considered uniformly 'malignant' when diagnosed and treated promptly.

Implications:

• Prompt diagnosis and comprehensive treatment, including HBOT and antibiotics, are crucial for favorable outcomes in NEO.
• The shift towards non-surgical management highlights therapeutic advancements.
• Effective control of NEO is achievable, significantly reducing morbidity and mortality.
