A Masing periosteal elevator is a surgical instrument used primarily in nasal and plastic surgery, particularly for elevating and separating the periosteum (a membrane covering bone) from underlying bone structures. It’s designed to aid in procedures like rhinoplasty, nasal fracture repair, and correction of septal deviations. The instrument is characterized by its double-ended design, with a central handle and angled blades for precise manipulation and access during dissections.
