Improved exposure of the operative site is always desired by the surgeon. Dissatisfied with the various retractors in use for endaural surgery, I perfected an instrument which has proved very adaptable during the past four years in mastoid and fenestration surgery.
The retractor is of stainless steel and is so designed that it may easily be altered during the operation to suit the requirements of the operator at that moment. The main retractor has two curved arms which are opened to the desired exposure by means of a thumb screw. Posterior retraction of the periosteum and soft tissues covering the mastoid portion of the temporal bone and anterior retraction of the periosteum and soft tissue covering the squamous temporalis and temporal muscle above the tragus are produced by turning the thumb screw at the base of the retractor.
Attached to the ends of the main retractor arms are two curved
