The Jansen Mastoid Retractor is a self-retaining instrument used for retraction during mastoid surgery. It allows the surgeon to get better access to the mastoid bone behind the ear.

These surgical retractors have the following patterns: 
•    Sharp Pattern
•    Blunt Pattern

The ring handle includes a ratchet to control the blade expansion. The ratchet mechanism locks the blades in place for easy exposure of the wound.
