Does the ChOLE classification relate to the duration of surgery?

Introduction: Cholesteatoma, a challenging entity in otologic surgery, necessitates a standardized classification system for effective communication among healthcare providers and consistent reporting of surgical outcomes. The ChOLE Classification System, introduced by Linder et al., stages cholesteatoma based on extension (Ch), ossicular chain status (O), life-threatening complications (L), and Eustachian tube function and mastoid pneumatization (E).

MRI Follow-up of Astrocytoma: Automated Coregistration and Color-Coding of FLAIR Sequences Improves Diagnostic Accuracy With Comparable Reading Time.

Background: MRI follow-up is widely used for longitudinal assessment of astrocytoma, yet reading can be tedious and error-prone, in particular when changes are subtle.

Purpose/hypothesis: To determine the effect of automated, color-coded coregistration (AC) of fluid attenuated inversion recovery (FLAIR) sequences on diagnostic accuracy, certainty, and reading time compared to conventional follow-up MRI assessment of astrocytoma patients.

Study Type: Retrospective.
