[Potential of computer-assisted navigation systems in the surgical treatment of chronic sinusitis, nasal cavity and paranasal sinuses tumors].

PURPOSE: To describe the principles of medical navigation systems in head and neck surgery, the possibility of their application and the existing limitations.

MATERIAL AND

METHODS

The article presents the generalized experience of image-guidance equipment using in the ENT Department of First Pavlov State Medical University. 298 operations, mostly FESS, were performed from 2013 to 2018 under the control of navigation system. The majority of cases consisted of surgical treatment of chronic sinusitis, tumors of the nasal cavity and paranasal sinuses; also, navigation control was useful in the case of altered intranasal anatomy after previous surgical treatment or due to chronic polyposis. A case report of frontal sinus inverted papilloma surgical treatment, controlled by an electromagnetic navigation system, is presented.

RESULTS

The use of navigation systems in head and neck surgery can improve surgery accuracy and safety, as well as providing a unique opportunity to learn FESS in real time.
