Overview
Brief Summary
The aim of this study was to investigate the effect of sphenopalatine ganglion (SPG) block bilaterally through a nasal device called Tx360 by delivering 0.3cc of lidocaine 2% for pain relief in patients with Trigeminal Neuralgia (TN).
Detailed Description
Trigeminal neuralgia (TN) is a chronic condition that causes sudden, intense facial pain that has a severe impact on patients' life quality and everyday functioning. Even with many treatments available, some patients still struggle to manage their pain effectively. Sphenopalatine ganglion (SPG) block, delivered through a recently introduced nasal applicator called Tx360, has shown promising results for those patients suffering persistent facial pain, icluding cases of TN. The purpose of this study was to observe how effective the SPG block delivering lidocaine 2% via the Tx360 is for pain relief in patients with TN. The patients' diagnosis included classical or atypical TN affecting the V2 (maxillary) or V3 (mandibular) branches, with partial or complete resistance to medication. Researchers measured pain levels using the Numerical Rating Scale (NRS) and evaluated the effects of treatment on patients' physical and mental wellbeing using the Short Form-36 (SF-36) Quality of Life Questionnaire.

Outcomes
Primary Outcomes
NRS pain score
Time Frame: From enrollment to the end of the follow-up period, which included an initial 6-week period, where the treatment was being administered, and a subsequent 12-week period post-treatment that served for follow-up purposes.
Outcome measures were assessed on a weekly basis for the initial 6-week treatment period, that is at every visit where SPG block would be administered, and on a monthly basis for the subsequent 12-week follow-up period, where patients participated in scheduled monthly follow-up calls. Patients were instructed to maintain a detailed pain diary for these 18 weeks and were asked about their pain intensity as measured with the Numerical Rating Scale (NRS) scoring system. NRS consists of a simple 11-point scale from zero to ten, where zero corresponds to non-existent pain and ten corresponds to the worst possible pain the patient has ever experienced. Patients choose the number that best corresponds to the intensity of their pain.
Secondary Outcomes
- changes in the 9 components measured by the SF-36 questionnaire(during the first visit to the clinic and 3 months after the completion of the treatment)
