Reintrat

Reintrat is a minimally invasive neurosurgical technique used to correct complex cranial nerve disorders that involve displacement or compression of neural tracts. The procedure, abbreviated as REINTAT, was first described by Dr. Andrea M. Kovács in a peer‑reviewed study published in 2012 and later refined in 2017 for use in the management of trigeminal neuralgia and certain vestibular disorders.

During a REINTAT procedure, a small cranial opening is made and a high‑resolution fiber‑tracking device is inserted to map the affected nerve corridor. The surgeon then performs a targeted decompression or realignment of the tract with minimal collateral tissue damage, often avoiding the need for larger craniotomies. The technique is performed under endoscopic visualization and real‑time electrophysiological monitoring, allowing the surgeon to preserve surrounding structures.

Clinical outcomes reported in the literature indicate that REINTAT achieves relief of pain or vertigo in up to 85 % of cases with a low rate of adverse events compared to conventional open approaches. The procedure has also been adapted for use in selected cases of external auditory canal stenosis and even in some ophthalmic nerve decompressions. Continual refinement of imaging protocols and instrument design is expanding the indications for REINTAT, with ongoing multicenter trials examining efficacy and safety in larger patient cohorts.
