Advancements in the Treatment of Necrotizing Otitis Externa with Hyperbaric Oxygen: A Systematic Review
Bibliographic record
Abstract
Abstract Necrotizing otitis externa (NOE), also known as malignant otitis externa (MOE), is a severe infection that begins in the external auditory canal and can extend to adjacent tissues and bone. It primarily affects elderly, diabetic, and immuno-compromised patients. Despite the advancements in antibiotics and surgical interventions, NOE remains a condition with significant morbidity and mortality. To evaluate the efficacy of hyperbaric oxygen therapy (HBOT) as an adjunctive treatment for NOE, focusing on clinical outcomes and the potential benefits in refractory or advanced cases. We conducted a comprehensive literature search on the PubMed/MEDLINE and Cochrane Library databases for articles published from January 1980 to December 2023. The search terms included hyperbaric oxygen therapy, necrotizing otitis externa, and refractory otitis. A total of 8 studies met the inclusion criteria, comprising case reports, observational studies, and case series. Study quality was assessed through the Cochrane Risk of Bias tool and the Newcastle-Ottawa Scale. The results indicate that HBOT shows promise in the treatment of NOE, with several studies reporting complete resolution of infection and prevention of recurrence, especially in refractory cases. The current evidence is insufficient to establish HBOT as a standard treatment for NOE; however, its potential benefits in improving clinical outcomes and reducing morbidity are significant. High-quality research, including randomized controlled trials, is necessary to validate the role of HBOT in NOE treatment. Where hyperbaric facilities are accessible, HBOT should be considered for refractory NOE cases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
