Tympanic part of temporal bone

Dr Henry Knipe et al.

The tympanic part of the temporal bone is situated inferiorly to the squamous part and anteriorly to the mastoid part.

The tympanic part surrounds the external auditory meatus, forming the anterior wall, floor and some posterior wall of the bony external acoustic meatus. The lateral border of tympanic part gives the attachment to the cartilaginous part of the external acoustic meatus. Its anteroinferior surface forms the posterior boundary of the mandibular fossa. It fuses medially with the petrous part and posteriorly with the squamous and mastoid part.
