Abstract

Trigeminal neuralgia (TN) is a debilitating facial pain syndrome that is often difficult to manage with standard treatments. Although specific regional anaesthesia techniques are available, they are rarely practised in the Emergency Department (ED). We discuss three cases of patients with severe, intractable TN pain unresponsive to oral medications, where an infraorbital nerve block (IONB) was performed for pain relief. IONB using an intraoral (classical) approach, a 30-gauge needle was inserted at the infraorbital foramen after antiseptic preparation, and 1 mL of 2% lignocaine combined with 1.5 mL of 0.5% bupivacaine was administered. All three patients experienced immediate pain relief, and no immediate adverse effects were observed. Follow-up over six months showed that two out of three patients had long-lasting pain relief, supporting the potential of IONB using local anaesthetics as a viable intervention for sustained pain relief. This case series highlights the effectiveness of IONB as an alternative treatment for trigeminal neuralgia in patients who do not respond adequately to conventional pharmacologic therapies in the emergency setting.
