Event Description

D¿ercole, m., izzo, a., silvestri, m., olivi, a., tufo, t.Percutaneous balloon compression for treatment of trigeminal neuralgia assisted by o-arm o2-based navigation: case series and review of the literature.Operative neurosurgery.2022.23 (464¿471) https://d oi.Org/10.1227/ons.0000000000000395 background: percutaneous cannulation of foramen ovale (fo) for treatment of trigeminal neuralgia, classically performed according to empirical landmarks and under fluoroscopic guide, may be difficult, time-consuming, and burdened with vascular or neurological complications related to close anatomic relationships.Objective: to investigate cannulation of fo for treatment of trigeminal neuralgia assisted by o-arm o2-based navigation, to assess safety and accuracy.Methods: nineteen patients underwent percutaneous balloon compression of gasserian ganglion assisted by navigation provided by o-arm o2 and stealthstation.Clinical outcomes according to barrow neurological institute pain score, time of recurrence, side effects, and complications, as well as technical aspects as time of the procedure and number of tracks were investigated and evaluated.Obtained data were compared with current literature in a systematic review.Results: the median time for procedure was 46 minutes; cannulation of the fo was performed in a median of 3 minutes and 47 seconds, in a single track in 16 patients, while 3 cases required a further o-arm acquisition to check the needle position.No complications were observed.Onset of facial hypoesthesia was recorded in 10 patients and dysesthesia in 5.Although at a median follow-up of 12.7 months 7 patients had recurrence after an average pain-free period of 7.3 months, all but 2 patients had improvement in pain score.Conclusion: advantages powered by navigation should be addressed in accuracy, lower complication rate, and success of cannulation even in case of previous treatments or anatomic variations, rather than in effective reduction of surgical time.Reported events: 3 cases with difficult access, a further o-arm acquisition was necessary to obtain an intraoperative check of the needle position.5 patients showed a worsening of pain dysesthesia was associated to hypoesthesia in 5 patients, all with a prolonged pain history and other previous treatments.Facial pain occurred in 3 patients.2 patients referred onset of contralateral trigeminal neuralgia see attached literature article.
