Abstract

Since the introduction of functional endoscopic sinus surgery (FESS), the procedure has undergone rapid change with evolution keeping pace with technological advances. The advent of low cost charge coupled device (CCD) cameras revolutionized the practice and instruction of FESS. Video-based FESS has allowed for documentation of the surgical procedure as well as interactive instruction during surgery. Presently, the technical requirements of video-based FESS include the addition of one or more television monitors positioned strategically in the operating room. Though video monitors have greatly enhanced surgical endoscopy by re-involving nurses and assistants in the actual mechanics of surgery, video monitors require the operating surgeon to be focused on the screen instead of the patient. In this study, we describe the use of a new low-cost liquid crystal display (LCD) based device that functions as a monitor but is mounted on the head on a visor (PT-Ol, Ol Products, Westlake Village, CA). This study illustrates the application of these HMD devices to FESS operations. The same surgeon performed the operation in each patient. In one nasal fossa, surgery was performed using conventional video FESS methods. The contralateral side was operated on while wearing the head mounted video display. The device had adequate resolution for the purposes of FESS. No adverse effects were noted intraoperatively. The results on the patients ipsalateral and contralateral sides were similar. The visor did eliminate significant torsion of the surgeon's neck during the operation, while at the same time permitted simultaneous viewing of both the patient and the intranasal surgical field.
