Middle-ear surgical retractors designed to temporarily separate and hold back the tissues and other anatomic structures surrounding the mastoid prominence of the temporal bone, exposing and providing access to the mastoid prominence (i.e., mastoid process). Mastoid process retractors are manual instruments available in a variety of shapes and styles. They usually include two adjustable blades at the distal end that are pivoted at the center and that have at the proximal end a threaded mechanism or scissors-like handles with a ratchet that retain the position once set (i.e., self-retaining retractors). They are used mainly in surgical procedures of the temporal bone mastoid process and surrounding middle-ear structures.
