Intraoperative Imaging and Computer-Assisted Surgery using the O-armTM Imaging System in Pediatric Skull Base Surgery

Abstract

Introduction: Computer-assisted surgery (CAS) in otolaryngology, in particular rhinologic and anterior skull base surgery, has become increasingly prevalent, and can enhance surgical intervention by being a powerful preoperative planning tool and providing real-time localization of instruments within the surgical field. Traditional CAS systems require preoperative CT scans performed on a calibrated scanner. The logistics of obtaining these scans can sometimes be difficult and may require coordinating a repeat scan prior to surgery. In the pediatric population, this can be particularly challenging as many of these patients may require sedation or general anesthesia. Also there are concerns regarding excessive radiation exposure in this population. We will describe the use of a new intraoperative imaging system which provides immediate axial, coronal, and sagittal CT images that are registered to the patient.
