Malignant otitis externa: experience with hyperbaric oxygen therapy.

With the low incidence of malignant otitis externa (MOE) and its variable manifestations, it is not possible to perform relevant prospective controlled studies in this condition. Therefore, the best evidence on which to base therapeutic decisions is likely to remain retrospective reviews of case series. Even though our knowledge in regard to MOE is not greatly increased by the retrospective case series by Saxby et al in this issue, nevertheless it has value.
