This study aimed to determine the effects of preoperative speech reception on postoperative speech recognition with a cochlear implant and to develop a statistical index allowing prediction of postoperative speech recognition before implantation.

Study Design:

The study design was a retrospective case review with statistical modeling.


The study was conducted at a tertiary referral center with an associated Veteran's Administration hospital.


Postlingually deafened adults with and without residual speech reception participated.


Cochlear implantation with Cochlear Corporation CI-22 and CI-24 devices was performed.

Main Outcome Measures:

Monosyllabic word recognition was measured.


Duration of deafness and preoperative sentence recognition are both significant predictors of word recognition with a cochlear implant and can account for 80% of the variance in word recognition.


Cochlear implant outcomes are variable but predictable within specific ranges.
