Abstract
OBJECTIVE: Recently, the neuronavigation system (NS) has become an essential intraoperative tool for many neurosurgical procedures allowing for precise lesion localization. For such reason, it is particularly important to avoid errors during the navigation process. In the present study focus on a novel technique with the palatal position of patient tracker to ensure an optimal accuracy during magnetic navigation in different neurosurgical procedures.
METHODS: The present retrospective study included a total of 34 patients treated in our Institution between June 2017 and January 2018. Surgical procedures included two groups operated under general anesthesia: microscopic transcranial approach and endoscopic endonasal approach. Preoperative and post-operative navigation accuracy was assessed by two different neurosurgeons.
RESULTS: After our surgical planning navigation protocol was applied, both transcranial and endonasal procedures were successfully performed under navigation guidance in all patients except one. Intraoperative and post-operative complications related to tracker mounted under the hard palate did not occur. In 33 cases a maximal tracking view and optimal navigation accuracy was achieved accounting for a successful rate of 97%.
CONCLUSIONS: The position of the patient tracker under the hard palate showed safety, accuracy and feasibility in 97% of our patient. In our case series, it allowed to obtain the main goal to avoid device displacement without invasiveness and postoperative discomfort of the patient.
