Predictive value of radiologic studies for malignant otitis externa: a systematic review and meta-analysis

ABSTRACT: Highlights • The initial diagnosis of necrotizing otitis externa has not been established.• CT and MRI are the currently preferred imaging modalities.• The diagnostic sensitivity of technetium-99m, gallium-67, and MRI was favorable.

Objective

To determine the diagnostic accuracy of Necrotizing Otitis Externa (NOE) based on radiologic studies.

Methods

The PubMed, Cochrane, Embase, Web of Science, SCOPUS, and Google Scholar databases were searched. True-positive and false-negative results were extracted for each study. Methodological quality was evaluated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool.
