摘要

Objective::To review the role of adjuvant hyperbaric oxygen therapy (HBOT) in the treatment of malignant otitis externa (MOE).Data sources::PubMed, Scopus, Web of Science, Science Direct, and Cochrane Library were searched for the following concepts: "hyperbaric oxygen" and "malignant or necrotizing otitis externa."Methods::Studies were included if they contained (1) patients with reported evidence of MOE, (2) employment of adjuvant HBOT, (3) details on patients’ medical condition, and (4) documented survival outcomes. Extracted information included patient demographics, underlying medical conditions, infectious etiology, signs and symptoms, medical and surgical treatments, duration of medical treatment, mean follow up time, HBOT setting, number of HBOT sessions, complications, survival rate, and all-cause mortality.Results::A total of 16 studies comprising 58 patients (mean age 68.0 years) were included. Diabetes was present in 94.7% of cases and Pseudomonas spp (64.3%) was the most common infectious agent. Cranial nerve VII was involved in 55.2% of cases. Overall, the disease cure rate with adjuvant HBOT was 91.4% and all-cause mortality was 8.6%. Among those who had cranial nerve VII involvement, 72.0% had return of function and 93.8% of them survived. Conclusion::HBOT may be an effective treatment option for refractory or advanced MOE but its efficacy remains unproven due to lack of strong scientific evidence. However, its therapeutic value should not be underestimated given good results and few adverse events reported in this study.
