L.M. is a 40 year old female with longstanding unilateral hearing loss. She has migraine headaches, and was told that was the likely cause of her hearing loss. She had read that cochlear implants can now be used to treat single-sided deafness, and came for audiological/ENT evaluation for that purpose.  Her audiogram and tympanograms are below. Word recognition was poor in the left ear. Acoustic reflexes could not be accurately measured because of the bilateral hypercompliance of the tympanograms.

• Does migraine in rare cases cause single-sided deafness?
• Can a cochlear implant be used?
• What are her other amplification options?
