Nerve Block Treatment for Chronic Jaw Pain

Study Summary: Nerve Block Treatment for Chronic Jaw Pain This study is being conducted at the TMJ (temporomandibular joint) clinic, which is part of the oral and maxillofacial surgery department. The goal is to evaluate how effective peripheral nerve blocks are in reducing long-term jaw pain in patients with chronic temporomandibular disorders (TMD) who haven't responded to at least two other types of treatment (such as physical therapy, medication, or bite splints). What Is the Treatment? Peripheral nerve blocks are injections that temporarily block nerve signals from the painful area. This can relieve pain and improve function. These blocks are already used routinely at the clinic. Who Can Join? Adults who have had jaw joint pain for over a year. Have tried at least two other treatments without success. Are mentally competent and not pregnant. What Will Participation Involve? You'll receive the nerve block treatment as part of your regular care. You'll be asked to attend follow-up visits, typically one every 4 months (3 per year). You'll be monitored for pain relief, mouth opening ability, and use of pain medications. You can stop participating at any time without affecting your care. How Will Data Be Handled? Your information will be stored securely and coded to protect your identity. Only the research team will have access to your personal information. How Many People Will Be in the Study? The goal is to recruit 40 patients.
