Understanding the Impact of Eardrum Conditions on Thermometry
In the wake of the COVID-19 pandemic, accurate body temperature measurement has become more crucial than ever. This review delves into a systematic review and meta-analysis that explores the influence of eardrum perforation and chronic otitis media on the accuracy of infrared tympanic thermometers in adults.

The Source Article's Abstract
This study was conducted to determine whether tympanic membrane perforation or chronic otitis media affects the results of an infrared tympanic membrane thermometer in adults.
A literature search was performed using PubMed, Embase, Cochrane Library, Web of Science, and Google Scholar.
Four nonrandomized studies were included in the analysis. The temperatures of the bilateral eardrums (one eardrum with normal condition [control group] and the other eardrum with perforation or chronic otitis media [experimental group]) were measured for the same subject in the studies. The mean and standard deviation of the bilateral tympanic membrane temperatures were used to calculate the mean difference (MD) with a corresponding 95% confidence interval (CI). The fixed-effect model was utilized based on the results of the heterogeneity measurement using the Chi2 test and I2 statistic. The results of a meta-analysis in the normal eardrum (control group) and perforated eardrum, chronic suppurative otitis media with tympanic membrane perforation, or chronic otitis media with cholesteatoma (experimental group) were 343 subjects (MD = 0.05; 95% CI = -0.00 to 0.11; P = .06). A meta-analysis of the normal eardrum (control group) and perforated eardrum or chronic suppurative otitis media with tympanic membrane perforation except for cholesteatoma (experimental group) found 296 subjects (MD = 0.05; 95% CI = -0.01 to 0.11; P = .10).
When the temperatures of the bilateral eardrums were measured using an infrared tympanic membrane thermometer, no difference was observed between the eardrum with perforation or chronic otitis media and the normal eardrum.

Methodology and Scope of the Study
The study conducted an extensive literature search, including databases like PubMed and Embase, to gather relevant data. It focused on nonrandomized studies where the temperatures of bilateral eardrums were compared – one in normal condition and the other with perforation or chronic otitis media.
Key Findings and Analysis
- The meta-analysis included 343 subjects, providing a comprehensive overview.
- No significant difference was observed in temperature readings between normal and affected eardrums.
- The study challenges the common assumption that eardrum conditions significantly alter thermometer readings.
Implications for Medical Practice
The findings suggest that infrared tympanic thermometers remain reliable even in the presence of eardrum perforation or chronic otitis media. This insight is crucial for medical professionals who rely on these devices for quick and accurate temperature measurements.
