Objectives:
The role of traditional nuclear medicine studies in the management of malignant otitis externa (MOE) is unclear and there are ongoing debates regarding their diagnostic value. The authors perform a systematic review and meta-analysis to assess the sensitivity and specificity of traditional nuclear medicine studies in the diagnosis of MOE.
Methods:
In accordance with PRISMA guidelines, a query of the Medline, Embase, Web of Science, and Cochrane databases was undertaken. The primary outcomes of interest were the sensitivity and specificity of traditional nuclear medicine studies to detect MOE.
Results:
Of the initial 1317 hits from the four databases, 20 articles with a combined 608 patients were ultimately included in the review. The pooled sensitivities for Technetium-99 and Gallium-67 were 85.1% (95% CI, 72.0-98.1%) and 71.2% (95% CI, 55.1-87.3%) respectively. The available evidence suggested poor specificity of these modalities, but was insufficient for meta-analysis. Neither modality was shown to be effective in the assessment of disease resolution.
Conclusion:
The sensitivities of Technetium-99 and Gallium-67 to detect MOE are less favorable than was initially thought. Given this finding and their poor specificity, lack of anatomic resolution, unproven ability to detect disease resolution and variable availability, this review does not support the routine use of these studies in the management of MOE.
