What It Is: A trigeminal nerve block is a procedure aimed at alleviating pain by injecting anesthetic around the branches of the trigeminal nerve, which is primarily responsible for sensation in the face. This block can be performed using different approaches, including the pterygopalatine fossa approach and the foramen rotundum approach. These methods target the nerve pathways through specific anatomical areas to effectively reduce pain signals sent to the brain.

How It Will Help: By blocking the trigeminal nerve, the injection can significantly reduce pain and improve quality of life for patients suffering from severe facial pain, such as trigeminal neuralgia or after shingles. The pterygopalatine fossa approach targets the nerve cluster that affects the midface region, while the foramen rotundum approach is more focused on the upper parts of the face. These techniques can provide rapid relief from pain, allowing patients to return to their daily activities with reduced discomfort.

Why It Is Safe: Trigeminal nerve blocks are generally safe when performed by an experienced practitioner using precise imaging guidance, such as fluoroscopy or ultrasound, to accurately place the needle. The risks of complications are low but can include temporary numbness or soreness in the injection area. Both approaches avoid major blood vessels and critical structures, minimizing the risk of serious side effects. The use of local anesthetics in the procedure also reduces the potential for systemic side effects, making it a safer option compared to long-term medication use.
