Abstract
Summary One possible use of CT navigated surgery in Otorinolaryngology includes traumatology of the facial skeleton. CT navigation enables a surgeon to assess the range and quality of reposition and fixation of a fracture, in our case the fracture of the orbital floor, using a navigated tube. We proceed from pre-operative CT of the paranasal sinuses images to navigation with 1,5-2,0 mm incisions and subsequent registration. Formerly, we used mainly transantral approach at our department, while currently we prefer subciliar approach with the use of absorbable materials (PDS or PMR splint). We use a rigid endoscope for infraorbital nerve decompression and delicate removal of free bone fragments from the maxillary sinus. We applied this procedure in 2 patients. We verified the range of decompression, degree of reposition of the orbital blow-out fracture, and placement of PMR splint and titanium grid using video navigation.
