Temporal Bone Resection

• Sleeve Resection: indicated for tumors of the concha, periauricular, or cartilaginous canal regions with sparing of the bony EAC, parotid, and TMJ; removes bone lateral to TM

• Lateral Temporal Bone Resection: indicated for tumors lateral to the TM (may involve outer layer of the TM); removes mastoid bone, TM, incus, and malleus (may spare otic capsule and facial nerve for select tumors)

• Total Temporal Bone Resection (controversial): indicated for tumors that involve the middle ear space, mastoid cavity, medial layer of the TM, or deep temporal bone; removes temporal bone lateral to the internal acoustic canal (subtotal resection often implies sparing of the petrous apex); results in anacusis, initial vestibular dysfunction, facial nerve paralysis, and CHL
