Left temporal bone (Os temporale)
Educational content only — not medical advice.
Anatomy
The left temporal bone: squamous, tympanic, petrous and styloid parts surround the left ear structures and share in the temporomandibular joint; it carries the mandibular fossa and mastoid process, and the facial canal crossing it ends at the stylomastoid foramen.
Clinical notes
Fracture of the left petrous part in severe head trauma can paralyse the same-side face and deafen the ear; it is always assessed on thin-cut CT when a skull-base injury is suspected.
