Surgery Of Paranasal Sinuses Guided By Images

Surgery guided by images is a system of three-dimensional mapping that combines computerized tomography and information in real time to locate exactly the position of the operative instruments by means of infrared or electromagnetic probes. In this way, the otolaryngologist "navigates" through the nasal passages in a more precise way when performing functional endoscopic paranasal sinuses surgery (FESS). In 2005, image-guided surgery (IGS) expanded from the field of neurosurgery, where it was originally used, to the surgery of paranasal sinuses, spine and orthopedic surgery. As the otolaryngologists were gaining experience, its use has been generalized, particularly in the following indications: • Surgery of the paranasal sinuses in the absence of normal anatomy • Revision of surgery of paranasal sinuses • Disease that is extending to the base of the skull • Disease extending to frontal or sphenoid sinuses • Surgery near the lamina papyracea. • Presence of orbital pathology Image-guided surgery provides the surgeon a more detailed view of the extra and intracranial structures such as: areas near the eyes, brain, arteries and major veins, and nerves that can be found during FESS. This technology is particularly useful in revision procedures of FESS where the effects of scarring may be present and common anatomical reference points are not already present or in such complex cases that the anatomy is distorted. FDA has approved for the process 510 (k) several systems for this purpose, namely: • InstaTrak 3000Plus System (GE OEC Medical Systems, Salt Lake City, UT) • StealthStation System (Surgical Navigation Technologies, Broomfield, CO) • VectorVision Cranial/ENT (BrainLAB AG, Heimstetten, Germany) • Stryker Navigation System ENT Module (Stryker Corporation, Kalamazoo, MI) • Fusion Compact Navigation System ( Medtronics,Lousville Colorado) <a id="
