OBJECTIVES: To investigate whether there is a difference between electrode frequencies estimated in OTOPLAN according to anatomy using a preoperative CT scan and electrode frequencies based on postoperative cone beam computer tomography (CBCT).

Discussion
Signed responses from readers of the wire.
If preoperative CT-derived OTOPLAN frequency estimates align sufficiently with post-surgical fitting values, audiologists may be able to start anatomy-based programming earlier and with greater confidence—but current data must be reviewed before changing fitting workflows.
Anatomy-based cochlear implant fitting is a growing paradigm, and validating preoperative CT estimates as a reliable starting point could streamline programming and improve early hearing outcomes.
- 01Uses OTOPLAN software to derive electrode frequency maps from preoperative CT anatomy.
- 02Compares preoperative frequency estimates to frequencies applied at actual CI fitting.
- 03Feasibility study design; not a randomized trial of outcomes.

- 05Relevant to audiologists and CI centers considering anatomy-based programming workflows.
Electrode frequency estimates derived from preoperative CT-based OTOPLAN modeling can approximate those used in actual cochlear implant fitting.
