A Mastoid Self-Retaining Retractor is a specialised ENT (Ear, Nose, Throat) surgical instrument used to hold soft tissues apart during mastoidectomy and ear surgeries. It features outward-directed sharp prongs and a locking mechanism that keeps the surgical field open without the need for manual assistance. The retractor provides excellent visibility and access for delicate bone and soft-tissue work in the mastoid region.
