Abstract The introduction of image guidance navigation system in endoscopic sinus surgeries has been highly advocated in the recent past era. Ever since its introduction in the 1980s and 1990s in Germany it has been asserted that the image-guided navigation enhances surgical outcomes and diminished perioperative morbidities. The objective of this study is to reflect the experience of our institute with the image guidance navigation system in the frontal sinus endoscopic surgeries, specifically due to its constricted anatomy and proximity to vital structures. Retrospective chart review was performed for all image guided endoscopic frontal sinus procedures Performed at a tertiary referral center of King Fahad Specialist Hospital Dammam during the period from 2010 to 2019. A total of 450 endoscopic sinus and skull base procedures were performed using different image guidance systems. Out of the 450 cases, 231 cases were indicated for frontal sinus involvement. The fundamentals of anatomical knowledge are essential for the success of any surgery including image-guided surgeries. Utilization of image-guidance in endoscopic frontal surgeries assists in portraying the way to targeted frontal disease. It aids in localizing vital structures in distorted anatomy thus avoiding undesirable complications.

Introduction The complexity of the frontal sinus anatomy marks it as a challenge for all otolaryngologists. Differing between individuals and even between sides endoscopic frontal sinusotomy remains a fearsome surgery. The grave complications that may occur with any frontal sinus surgery, add to the elevated rate of failure and recurrence heightens that fear [1]. The introduction of computer tomography guided surgeries alleviated the struggle of accessing the frontal sinus nevertheless the fear of injury of the adjacent vital structures remains an obstacle [12]. This study displays the application of computer tomography guided surgeries in versatile frontal sinus pathologies eliminating the need of external approaches.
Aim and Objectives Reflection on the clinical value and applications of imageguided endoscopic frontal sinus surgeries at a tertiary hospital setting.
Material and Methods A retrospective study of all image guided endoscopic frontal sinus procedures performed at a tertiary referral center of King Fahad Specialist Hospital-Dammam during the period from 2010 to 2019. A preoperative CT scan of paranasal sinuses was obtained for all patients according to the standard navigation-protocol. The CT scan acquisition protocol requires contiguous 1 mm thickness
