Cochlear Apex Triangulation Utilizing Ct Measures And Middle Ear Landmarks.

ABSTRACT:

Objective

To better characterize the cochlear apex in relation to surgically relevant landmarks to guide surgeons and improve procedural success of apical electrode placement.

Study design

Retrospective image analysis.

Setting

Tertiary referral center.

Patients

Cochlear implant recipients with available preoperative computed tomography (CT) imaging.

Intervention

None.

Main outcome measure

Cochlear dimensions and cochlear apex distance measures to surgically relevant middle ear landmarks and critical structures.

Results

Eighty-two temporal bone CT scans were analyzed utilizing multiplanar reformats. The average lateral width of promontory bone over the cochlear apex was 1.2 mm (standard deviation [SD], 0.3). The anteroposterior distance from
