This atlas contains a series of paired images correlating the radiologic and histologic anatomy of the normal temporal bone.  

 

The radiologic images were acquired from a 7 year old male with no history of otologic disease.  They were acquired on a multidetector Siemens CT scanner in the axial plane with 0.5 mm collimation.  The images have been arranged from anterior to posterior. 

 

The light microscopic images were acquired from the right ear of a different individual (87 year old female) with no known history of otologic disease.  The cause of death was coronary artery disease.  The postmortem time was 9 hours.  The temporal bone was fixed in 10% formalin, decalcified using EDTA, embedded in celloidin and serially sectioned at a thickness of 20 microns.  Sectioning was done in the vertical plane to correspond with the same plane used in the CT scans.  The atlas displays every 40th section stained with hematoxylin and eosin.

 

The radiologic and histologic images have been paired to show the anatomy at approximately the same level.  The viewer can magnify each image by clicking in it.  Use the right click button on your mouse to download each image to your desktop.
