NCT06998420

Brief Summary

This clinical study aims to investigate adverse outcomes following percutaneous balloon compression (PBC) of the trigeminal ganglion, establish a predictive model, and assess the probability of postoperative complications.The main question it aims to answer is:

  1. 1.What factors are associated with adverse postoperative outcomes?
  2. 2.What is the occurrence probability of different types of adverse outcomes? The study will record patients' demographic and clinical characteristics, laboratory test results, and conduct follow-ups at 3, 6, and 12 months postoperatively.

Outcome Measures

Primary Outcomes (3)

  • Pain recurrence (BNI≥Ⅲ)

    BNI Pain Intensity Scale Score: I:No pain,no medication II:Occasional pain,not requiring medication III:Some pain,adequately controlled with medication IV:Some pain,not adequately controlled with medication V:Severe pain/no pain relief

    Follow-up timepoints: 3, 6, and 12 months postoperatively (final determination based on preliminary observation endpoints)

  • Severe sensory impairment (facial numbness with BNI sensory score ≥ Grade III)

    BNI Pain Intensity Scale Score: I:No pain,no medication II:Occasional pain,not requiring medication III:Some pain,adequately controlled with medication IV:Some pain,not adequately controlled with medication V:Severe pain/no pain relief

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

  • Masticatory dysfunction (bite force reduction ≥50% or subjective weakness)

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

Secondary Outcomes (4)

  • Mild sensory abnormalities (BNI sensory score Grade II)

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

  • Diplopia or hearing loss (rare complications to be recorded)

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

  • Postoperative infection (puncture site/intracranial)

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

  • Psychological status (change in HADS score)

    3 months, 6 months, and 12 months postoperatively (determined based on prior observation endpoints).

Study Population

Patients who underwent PCGG surgery at the Pain Department of Affiliated Hospital of Nantong University between 2022 and 2024 and were willing to participate in postoperative follow-up were selected as the study subjects.

You may qualify if:

  • Age ≥18 years
  • Willing to complete postoperative follow-up

You may not qualify if:

  • Secondary trigeminal neuralgia (e.g., tumor compression, multiple sclerosis)
  • Previous interventional treatments for trigeminal neuralgia
  • Incomplete follow-up data
  • General anesthesia contraindications or significant dysfunction of major organs (cardiac, pulmonary, hepatic, renal) or severe neurological impairment
