Repeat posterior fossa exploration and external neurolysis for recurrent trigeminal neuralgia following microvascular decompression.

ABSTRACT:

Objective

Recurrence of trigeminal neuralgia (TN) after microvascular decompression (MVD) poses a challenge for neurosurgeons. This study aimed to investigate the effect of repeat posterior fossa exploration (RPFE) and external neurolysis for TN recurrence following MVD.

Methods

Totally, 38 TN patients who experienced recurrence after MVD were included. All patients underwent RPFE and limited neurolysis. The Barrow Neurological Institute Pain Intensity Scale were utilized to evaluate preoperative pain and postoperative outcomes.

Results

The median follow-up period was 63.8 months (range: 5-112 months). Thirty-three out of the 38 patients achieved excellent outcomes, 4 had good outcomes, and 1 experienced failure. The rates of complete pain relief was 92% immediately p
