Objective:
To evaluate the clinical value of neuronavigation system in stomatology.
Methods:
The clinical data of 3 patients were reviewed. Thin-slice CT scanning was conducted on the 3 patients and the CT data were input into the CT neuronavigation system that in turn guided the operations later. Patient I with trigeminal neuralgia, aged 51, underwent puncture of oval foramen and radiofrequency thermo-coagulation therapy. Patient II of canister shots injury, aged 32, with 3 metal grains in the face and 1 metal grain in the neck, underwent removal of the metal grains. Patient III with relapse of tongue cancer after operation, aged 62, underwent plantation of radiate granules.
Results:
Guided by neuronavigation, puncture was accurate and curative effect was excellent in patient I, and no visible complication was seen; all the metal grains in face were found and removed in patient II, however, because of registration error, the metal grain in neck failed to be positioned; and the radiate granules were implanted accurately in patient III.
Conclusion:
Neuronavigation significantly increases the successful rates of puncture into the oval foramen, orientation of metal grains, and implantation of radiate granules, and reduces the complications rate.
