Positioning for Middle Cranial Fossa Repair of Superior Semicircular Canal Dehiscence.

Abstract

Superior semicircular canal dehiscence (SCD) repair through the middle cranial fossa approach is typically performed on a patient in the supine position and the patient’s head is turned to the contralateral side and secured with surgical pinions or supported on a headrest. However, traditional supine positioning method may place strain on the patient’s neck, limit the surgeon’s visualization of the dehiscence due to inadequate head rotation, and compromise the ergonomic positioning of the surgeon. Here, we present a novel positioning method for middle fossa SCD repair that allows for optimal head rotation in a semi-supine position, requires less set-up and patient manipulation than the park bench position, and does not require the use of surgical pins.
