Abstract

The ear consists of pinna (auricle), external auditory canal (EAC), tympanic membrane, middle ear (containing the auditory ossicles), and inner ear in the petrous portion of the temporal bone (consisting of the bony and membranous labyrinth). Primary middle ear and temporal bone tumors are rare, but external ear cutaneous malignancies may involve these structures. BCC >> SCC for malignancies of the external ear, but SCC accounts for 85% of EAC, middle ear, and mastoid tumors. Nodal metastases occur in <15% with lymphatic drainage to parotid, cervical, and postauricular nodes.
