title: Percutaneous retrogasserian glycerol rhizotomy for trigeminal neuralgia: A simple, safe, cost-effective procedure.
abstract: OBJECTIVE
  Trigeminal neuralgia (TN) is a condition that has been studied over decades and whose pathogenesis has still not been well defined. Various open and minimally invasive procedures are in vogue for the treatment of intractable TN. All these procedures have their complications and recurrence rates. Percutaneous retrogasserian glycerol rhizotomy (PRGR) is one of the minimally invasive procedures that have been popular for quite a long time.
  
  
  METHODS
  This paper is a prospective study analyzing the results of 93 patients with refractory TN who were treated with PRGR.
  
  
  RESULTS
  There was an immediate pain relief in 96.8% of patients and long-term pain relief in 89.4% of patients, with a mean follow-up duration of 18.8 months. Recurrence of pain was seen in 10.4% of patients.
  
  
  CONCLUSIONS
  The PRGR is a simple, safe, cost-effective procedure without any need for expensive equipment and with a good outcome that is compared to the other relatively more expensive open and minimally invasive procedures.
