Navigation Systems are used to reduce complication rates, completely remove the disease, and hasten recovery after surgery. Image-guided surgery compensates the limitations of surgical endoscopy and is used as an important tool for Sinus Surgery. It has also demonstrated great promise in recent literature. Advances in portable MRI and volumetric CT technology have enhanced the efficiency and safety of intra-operative imaging.
Despite the availability of excellent nasal telescopes and high-resolution preoperative computed tomography (CT), major complications such as blindness, central nervous system (CNS) trauma, and even death still occur, because the traditional ESS may be compromised by anatomic complexity or intraoperative bleeding.
Sinus surgery has markedly improved with the introduction of surgical navigation systems, preoperative imaging techniques and intra-operative visualization tools.
