Core Tip

Core Tip: This study demonstrates that preoperative high-resolution computed tomography (HRCT) is a decisive tool for planning cochlear implantation in patients with chronic otitis media. Complete mastoid opacification on HRCT reliably predicts the need for radical surgery (canal wall-down/subtotal petrosectomy), whereas a clear mastoid permits a conservative (canal wall-up) approach. HRCT also accurately detects cochlear ossification, enabling crucial preoperative preparation. We propose a novel imaging-based decision algorithm to standardize surgical strategy, minimize intraoperative surprises, and optimize patient outcomes in these complex cases.
