image guided Surgical Navigation in otology
Laryngoscope, 2012Co-Authors: Darius Kohan, Daniel JethanamestAbstract:Objectives/Hypothesis: To evaluate the efficacy of Image-Guided Surgical Navigation (IGSN) in otologic surgery and establish practice guidelines. Study Design: Prospective study. Methods: Between January 2003 and January 2010, all patients requiring complicated surgery for chronic otitis media, glomus jugulare, atresia, cerebrospinal fluid leak with or without encephalocele, and cholesterol granuloma of the petrous apex were offered IGSN. The accuracy of IGSN relative to pertinent pathology and 11 anatomic landmarks was established. Additionally IGSN-related operative time, complications, and Surgical outcome were recorded. Results: In the study period there were 820 otologic procedures, among 94 patients (96 ears) with disease meeting proposed criteria. Thirteen patients (15 procedures) consented to the use of IGSN. All patients had a minimum 6 months of follow-up. The average additional operative time required was 36.7 minutes. The mean accuracy error was 1.1 mm laterally at the tragus but decreased to 0.8 mm medially at the level of the oval window. The mean accuracy of IGSN was within 1 mm in 10 of the 11 targeted Surgical anatomic landmarks. Conclusions: Interactive Image-Guided Surgical Navigation during complex otologic surgery may improve Surgical outcome and decrease morbidity by providing an accurate real-time display of Surgical instrumentation relative to patient anatomy and pathology. In select cases, the extra cost of imaging immediately prior to surgery and extra operating room time may be compensated by enhancing the ability to distinguish distorted anatomy relative to disease, potentially improving Surgical outcome. IGSN, although useful, does not replace Surgical expertise and experience.

removal of small foreign bodies from the maxillary sinus using ct image guided Surgical Navigation and rapid paired point registration and calibration with reference markers on an occlusal splint
Oral and Maxillofacial Surgery Cases, 2019Co-Authors: Hitoshi Sato, Sunao Shiogama, Kyoichi Narihira, Junichiro Chikuda, Shinsuke Nakamura, Yuzo Abe, Motohiro Tanaka, Tatsuo ShirotaAbstract:Abstract Computed tomography (CT)-guided Surgical Navigation is useful for removing foreign bodies from the maxillofacial region. Accuracy and speed of registration and intraoperative calibration are essential for functional intraoperative Navigation. A case in which foreign bodies were removed from the maxillary sinus using paired-point registration and calibration with reference markers on an occlusal splint for CT-guided Surgical Navigation is reported. A 49-year-old woman presented with spontaneous right cheek pain. Panoramic radiography showed two foreign bodies in her right maxillary sinus. Under general anesthesia, an occlusal splint with reference markers was set on the maxillary dental arch, and the anterior wall of the maxillary sinus was exposed. Foreign bodies were identified using an infrared optical Kick® Navigation System (Brainlab AG, Munich, Germany). The anterior wall of the maxillary sinus closest to the foreign bodies was penetrated with a trephine bur, the foreign bodies were removed, and the wound was completely closed. Several repeated calibrations were required to obtain accurate positional information about the foreign bodies during the surgery, but these were completed within 30 seconds. Histopathological findings and the postoperative clinical course indicated that the spontaneous right cheek pain was due to maxillary sinusitis with granulomatous inflammation caused by the foreign bodies. CT-guided Surgical Navigation using an occlusal splint with reference markers was useful for locating the foreign bodies in this patient, and rapid calibration allowed accurate positional information to be obtained during surgery to remove them from the maxillary sinus.

stereotactic Navigation for tamis tme opening the gateway to frameless image guided abdominal and pelvic surgery
Surgical Endoscopy and Other Interventional Techniques, 2015Co-Authors: S Atallah, George Nassif, Sergio W LarachAbstract:Background Frameless stereotaxy is an established method for real-time Image-Guided Surgical Navigation in neurological surgery. Though this is capable of providing sub-millimeter accuracy, it has not been used by other Surgical specialists.
