Since the introduction of functional endoscopic sinus surgery (FESS) in the United States in 1985, the information gained from imaging has proved imperative in understanding regional morphology and guidance of surgical procedures. More than 20 years later, the importance of imaging continues to be the anatomic detail afforded by this technology, the roadmap it provides in planning the surgery, and the morphologic detail it provides in recurrent disease. The latest development in CT technology, cone beam CT instrumentation, may change the way imaging of the nasal cavity and paranasal sinuses is performed in the future. These topics are discussed in this article.

Intraoperative imaging for otorhinolaryngology-head and neck surgery.
The applications of endoscopic techniques have expanded beyond the treatment of inflammatory sinus disease and toward the resection of anterior and middle skull base lesions. Image-guided surgery has emerged as an important tool that compensates for the limitations of surgical endoscopy. The disadvantage of image-guided surgery, however, is its dependence on preoperative imaging data. ⋯ It has had an impact on surgical decision-making during functional endoscopic sinus surgery and the resection of anterior skull base neoplasia. Advances in portable MRI and volumetric CT technology have enhanced the efficiency and safety of intraoperative imaging. Although further studies are required to quantify the precise utility of this new technology, it appears that intraoperative imaging will be an important tool for rhinologic surgery.
