The navigation system is used to reduce complication rates, completely remove the disease, and hasten the recovery after surgery. Image-guided surgery compensates the limitations of surgical endoscopy and used as an important tool for Sinus surgery and has 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 intra operative bleeding.
Sinus surgery has markedly improved with the introduction of surgical navigation systems, preoperative imaging techniques and intra operative visualization tools.
