As such, their conclusion was that the primary limiting factor for radiation dose reduction is the surgeon's willingness to accept impaired image quality. The technical storage or access that is used exclusively for statistical purposes. 1, 23.9% of patients (278/1162) referred for sinus CT by sinus surgeons underwent ESS with imaging guidance, whereas this percentage was 11.4% (151/1323) for the remainder of the ENT department. Some studies in image guidance have focused on real-time updates, which allow the preoperative images used for navigation to be updated throughout the surgery. Acute cerebral venous sinus thrombosis (VST) is a rare form of stroke, and establishing a correct diagnosis can be challenging due to its diverse and typically delayed clinical presentation [1,2].VST is most common in young women and is associated with pregnancy/puerperium, use of hormonal contraceptives, hypercoagulable states, and malignancy [3,4]. He was started on intravenous antibiotics and underwent external frontal sinusotomy to decompress the adjacent infected frontal sinus. Creates 3-D imaging models for surgical procedures. Sinusitis is one of the most common diseases treated by primary care physicians. IGS begins with obtaining a CT scan. Of the 3702 sinus CTs ordered by nonotolaryngology providers, 167 surgeries with intraoperative navigation (4.5%) were performed. Fried MP, Morrison PR.

Additionally, the navigation system confirms the positions of the surgeons instruments by superimposing them on the CT scan images. Paranasal sinus mucoceles are benign, expansive, cystic lesions which arise from retention of mucus secretions. Bone window views provide excellent resolution and a good definition of the complete osteomeatal complex and other anatomic details that play a role in sinusitis.2 The coronal view also correlates best with findings from sinus surgery. Stammberger H. Functional Endoscopic Sinus Surgery. After a prolonged course of antibiotics, serial CT scans revealed resolution of the frontal abscess and sinusitis. CT images are indeed able to better delineate the bony anatomy of sinonasal cavities for the nasal approach performed by the otolaryngologist, whereas the neurosurgeon will require the assistance of MRI guidance with enhanced intracranial soft tissue definition to pursue the combined procedure. Summary health statistics for US adults: National Health Interview Survey, 2012. CONSENTING FORMS. Adopting a single universal sinus CT protocol for diagnostic imaging and intraoperative navigation can be an effective means of decreasing cost and radiation exposure.
