Prompt TTM application may help to improve outcomes, but it is often hindered by technical problems, mainly related to the portability of cooling devices and temperature monitoring systems. Tympanic temperature (T\n                      <jats:sub>Ty<\/jats:sub>\n                      ) measurement may represent a practical, non-invasive approach for core temperature monitoring in emergency settings, but its accuracy under different TTM protocols is poorly characterized. The present scoping review aimed to collect the available evidence about T\n                      <jats:sub>Ty<\/jats:sub>\n                      monitoring in TTM to describe the technique diffusion in various TTM contexts and its accuracy in comparison with other body sites under different cooling protocols and clinical conditions.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      The scoping review was conducted following the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for scoping reviews (PRISMA-ScR). PubMed, Scopus, and Web of Science electronic databases were systematically searched to identify studies conducted in the last 20 years, where T\n                      <jats:sub>Ty<\/jats:sub>\n                      was measured in TTM context with specific focus on pre-hospital or in-hospital emergency settings.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The systematic search identified 35 studies, 12 performing T\n                      <jats:sub>Ty<\/jats:sub>\n                      measurements during TTM in healthy subjects, 17 in patients with acute cardiovascular events, and 6 in patients with acute neurological diseases.

Direct comparisons to other core temperature measurements from other body sites were available in 22 studies, which showed a faster and larger change of T\n                      <jats:sub>Ty<\/jats:sub>\n                      upon TTM compared to other core temperature measurements. Direct brain temperature measurements were available only in 3 studies and showed a good correlation between T\n                      <jats:sub>Ty<\/jats:sub>\n                      and brain temperature, although T\n                      <jats:sub>Ty<\/jats:sub>\n                      displayed a tendency to overestimate cooling effects compared to brain temperature.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      T\n                      <jats:sub>Ty<\/jats:sub>\n                      was capable to track temperature changes under a variety of TTM protocols and clinical conditions in both pre-hospital and in-hospital settings.
