简介：Objective:InfraredTympanicThermometer(ITT)isoneofthemostusefulinstrumentsforaccuratelymeasuringtemperature.TheeffectsofearpathologiesonITTmeasurementremainunclear.Thepurposeofthisstudyistodetermineiftympanicmembraneperforation(TMP)affectsITTmeasurementsinadultpatients.Materialandmethods:Atotalof90adultpatientswithmonauralcentralTMPwereenrolledinthisstudy.Patientswerecategorizedintothreesubgroupsaccordingtoperforationsize(1-3mm,4-7mm,and8-10mm).Thetympanictemperaturesoftheaffectedandunaffectedsites,andsubgroupswerecomparedwitheachother.Results:Thisstudycontained54(60%)malesand36(40%)femalesrangingfrom20to58yearsofage(meanage:30.74±9.61years).ThemeantympanictemperatureofthesideaffectedwithTMPwas36.34oC±0.61oC.Themeantympanictemperatureoftheunaffectedsidewithhealthyandintacttympanicmembranewas36.33oC±0.6oC.ThePearsoncorrelationscoreforthetympanictemperaturesandthesizeofTMPwas0.22whichwasnotsignificant(r=-0.12).Conclusion:TMPandperforationsizedonotaffectITTmeasurementsinadultpatients.
