Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Audiology

Background:

  • Bilateral cochlear implantation (BiCI) offers advantages over unilateral implantation.
  • Sequential BiCI requires multiple surgeries and longer rehabilitation.
  • Simultaneous BiCI may expedite binaural hearing restoration and reduce patient burden.

Purpose of the Study:

  • To review institutional experience with simultaneous bilateral cochlear implantation (BiCI) in adults.
  • To assess the feasibility and safety of simultaneous BiCI.
  • To compare potential benefits against sequential BiCI.

Main Methods:

  • Retrospective study of adult patients undergoing simultaneous BiCI (2010-2023).
  • Feasibility assessed via postoperative evaluations, outpatient visits, discharge status, and device fitting.
  • Data collected on patient demographics, hearing loss etiology, and complications.

Main Results:

  • Twenty-seven adult patients received simultaneous BiCI; mean age 37 years.
  • 88.8% had uneventful postoperative periods; 81.5% had uncomplicated initial outpatient visits.
  • 96.2% experienced no intraoperative complications; recovery was generally straightforward.

Conclusions:

  • Simultaneous BiCI is a feasible procedure in adults.
  • It avoids major intraoperative complications and lengthy recovery.
  • This method offers benefits by reducing surgical procedures and hospital admissions compared to sequential implantation.
