Cochlear implantation is a viable option for patients with hearing loss due to polyarteritis nodosa. This study details a successful case, offering hope for improved hearing outcomes in this patient population.

Area of Science:

  • Otolaryngology and Immunology
  • Vascular Inflammation and Auditory Health

Background:

  • Polyarteritis nodosa (PAN) is a systemic vasculitis affecting small to medium muscular arteries.
  • Progressive bilateral sensorineural hearing loss is a recognized otologic manifestation of PAN.
  • No prior reports exist on cochlear implantation in patients diagnosed with polyarteritis nodosa.

Observation:

  • A 71-year-old male with biopsy-confirmed polyarteritis nodosa presented with progressive bilateral sensorineural hearing loss.
  • The patient underwent cochlear implantation with a Nucleus 3G electrode array.
  • Surgical and post-operative recovery was uneventful, with no complications.

Findings:

  • Successful full insertion of the cochlear implant electrode array was achieved.
  • The patient reported immediate subjective improvement in hearing.

  • At three months post-implantation, the patient demonstrated useful open-set speech perception.

    • Implications:

    • Cochlear implantation can be a successful treatment for sensorineural hearing loss in patients with polyarteritis nodosa.
    • Surgeons should be aware of potential cochlear fibrosis or ossification in the basal turn, identified in a review of temporal bones from patients with hearing loss and PAN.
    • This case establishes a precedent for considering cochlear implantation in similar patients, potentially improving quality of life.
