Self-retaining retractors of various kinds are used in otolaryngologic operations. In brief, they are the self-retaining retractors for mastoidectomy and those for external frontoethmoidectomy. Each kind seems to have its own usefulness and merit.
The self-retaining retractor presented here is a combined, interchangeable, detachable and reversible one for use in mastoidectomy and in external frontoethmoidectomy. It consists of two parts: (1) a spreader with French lock joints on the legs and (2) blades with prongs of various sizes and types for specific operations (fig. 1). As a retractor for mastoidectomy, each leg of the spreader is fitted with a blade of three, four or more prongs to suit the surgeon's needs (fig. 2A). For external frontoethmoidectomy, the slotted blade desired for the retraction and protection of the orbital contents is attached to one leg of the spreader, and the blade with four prongs is fitted to the other for use
