The tympanic part of temporal bone is a curved bony plate beneath the squamous part and ahead of the mastoid process. Inside, it merges with the petrous segment of the temporal bone. The tympanic part makes up the front wall, the base, and a segment of the back wall of the external acoustic meatus.

The tympanic plate is this anterior wall segment of the tympanic portion of the temporal bone, interposed between the external auditory canal and the glenoid fossa (Fig 1).
