Abstract

Insights

Elderly patients and longer disease duration increase the risk of facial herpes simplex (FHS) after trigeminal neuralgia (TN) percutaneous microballoon compression (PMC). Male gender and higher CD8+ T cell counts are protective factors against FHS development.

Area of Science:

  • Neurosurgery
  • Infectious Diseases
  • Immunology

Background:

  • Percutaneous microballoon compression (PMC) is a key treatment for trigeminal neuralgia (TN).
  • Post-PMC facial herpes simplex (FHS) infection, caused by herpes simplex virus type 1 (HSV-1), is a known complication.
  • The prevalence and risk factors for FHS post-PMC require further investigation.

Purpose of the Study:

  • To identify potential risk factors for developing facial herpes simplex (FHS) in trigeminal neuralgia (TN) patients following percutaneous microballoon compression (PMC).

Main Methods:

  • A retrospective analysis of 181 TN patients undergoing PMC between September 2019 and August 2020.
  • Patients were categorized into FHS and non-FHS groups based on post-operative HSV-1 infection.
  • Demographic, clinical, laboratory, and surgical data were analyzed using univariable and multivariable logistic regression.

Main Results:

  • The incidence of FHS post-PMC was 27.07% (49/181) among patients without prior FHS.
  • Univariable analysis identified gender, age, disease duration, and CD8+ T cell count as significant variables.
  • Multivariable analysis revealed independent risk factors for FHS: older age (OR 1.169), longer disease duration (OR 1.361), and male gender (OR 0.061) and CD8+ T cell count (OR 0.993) as protective factors.

Conclusions:

  • Elderly patients and those with a longer duration of trigeminal neuralgia are at higher risk for developing FHS after PMC.
  • Male gender and higher CD8+ T cell counts appear to be protective factors against FHS development in this patient cohort.
