Objective:Totestthefeasibilityofmeasuringfinetemporalbonestructuresusinganewlyestablishedcone-beamcomputedtomography(CBCT)system.Materialsandmethods:Sixformalin-fixedhumancadavertemporalboneswereimagedusingahigh-resolutionCBCTsystemthathas900framesandcoppertaluminumfiltration.Finetemporalbonestructures,includingthoseofthefacialnervecanalandvestibularstructures,wereidentifiedandmeasured.Results:Thefinestructuresofthemiddleear,includingthetympanicmembrane,tendonofthetensortympani,cochleariformprocessofthesemicanalofthetensortympani,pyramidaleminence,footplateofthestapes,fullpathofthefacialnervewithinthetemporalbone,supralabyrinthinespace,semicircularcanals,pathwayofthesubarcuatecanal,andfullpathofthevestibularaqueduct,wereclearlydemonstrated.Thevestibularaqueducthasamidpointwidthof0.4±0.0mmandopercularwidthof0.5±0.1mm(mean±SD).Thelengthoftheinternalacousticmeatuswas10.6±1.2mm(mean±SD),andthediameteroftheinternalacousticmeatuswas3.7±0.3mm(mean±SD).Conclusion:Thisnovelhigh-resolutionCBCTsystemhaspotentiallybroadapplicationsinthediagnosisofinnereardiseaseandinmonitoringassociatedpathologicalchanges,surgicalplanning,navigationfortheearsurgery,andtemporalbonetraining.
