Trigeminal Neuralgia (TN) is a debilitating condition characterized by sudden, severe facial pain. Traditional treatments often fall short, leading researchers to explore alternative therapies. One such approach involves the Sphenopalatine Ganglion (SPG) block administered via the Tx360EU nasal applicator.
Study Overview
A prospective observational pilot study evaluated the efficacy of SPG block using the Tx360EU device in 15 adult patients with drug-resistant TN affecting the maxillary (V2) or mandibular (V3) branches. Over six weeks, participants received weekly bilateral SPG blocks with 0.3 cc of 2% lidocaine. Pain levels were assessed using the Numerical Rating Scale (NRS), and quality of life was measured with the Short Form-36 (SF-36) questionnaire.
Results
The study reported a significant and continuous decrease in NRS scores throughout the six-week treatment period and up to one month afterward. Subsequent assessments over the following two months indicated stable pain levels. Additionally, participants experienced notable improvements in physical functioning, energy levels, emotional well-being, and general health, as reflected in the SF-36 scores.
Discussion
These findings align with previous studies highlighting the potential of SPG blocks in managing various head and facial pain conditions, including TN. The Tx360EU device offers a minimally invasive, rapid, and precise method for delivering anesthetic agents to the SPG, with a favorable safety profile. Common side effects were mild and transient, such as nasal discomfort and a bitter taste.
Conclusion
Repetitive SPG block with 2% lidocaine administered via the Tx360EU nasal applicator appears to be a simple, effective, and well-tolerated adjunctive treatment for patients with drug-resistant TN. The study suggests that this approach can provide significant pain relief and enhance the quality of life for affected individuals. Further research with larger sample sizes and randomized controlled trials is warranted to confirm these findings and optimize treatment protocols.
