Radio-clinical assessment of crista fenestra during pediatric cochlear implantation.

Objectives: This study aimed to assess the ability of preoperative computed tomography (CT) to predict the crista fenestra (CF) type during cochlear implantation and correlate these types with intraoperative findings. This may allow for precise preoperative planning with better surgical outcomes.

Study Design: A prospective observational study.

Morphological classification of crista fenestra of round window corridor during pediatric cochlear implantation.

Objectives: This study aimed to document the observation of the Crista Fenestra's morphological types (CF) of the round window and to detect its impact during cochlear implant operation.

Study Design: A prospective descriptive cohort study.

Settings: We conducted this study at tertiary referral institutions in Egypt.

Cadaveric Study of Crista Fenestra: Revisited.

Objectives: Since there is great confusion in the literature about the anatomy and terms of the crista fenestra (CF) and the crista semilunaris, this paper is confined to the anatomy of the inferior margin of the round window (RW).

Methods: This study was carried out on 20 cadaveric temporal bones. We measured the maximal height of the RW and the maximum height of the inferior bony edge of the RW, (termed CF type A), in this study.
