Objective: Alter medication failure, patients with refractory trigeminal neuralgia (TGN) often present urgently and seek more potent or invasive therapies such as opioids or surgical options. Peripheral nerve blocks, safe and simple, may offer extended pain relief prior to opioid use or more invasive ganglion level procedures. Methods: We report a retrospective case-series (urgent care, at a large urban medical center, over a 2 year period) of nine patients with intractable primary TGN who underwent peripheral trigeminal nerve blocks after failing conservative medical therapy. After antiseptic skin preparation, a 30 g needle was inserted localizing to the supraorbital, infraorbital, and mental foramens. 0.5 mL of 0.25% bupivicaine:1% lidocaine was injected locally at all three foramens. Then, 1 mL of the above was injected in the region of the auriculotemporal nerve (see Video 1). All injections were done on the side with TGN pain. Results: All nine patients experienced immediate pain relief of >50% with 7 of 9 being completely pain free or just mild paresthesia Six of nine patients had lasting pain relief (1-8 months); three patients reporting pain now tolerable with adjunct medication and two patients were completely pain free. Conclusions: The treatment paradigm for TGN remains unclear when a patient fails conservative medical therapy. In this case series, many patients achieved rapid and sustained TGN pain relief with peripheral trigeminal nerve blocks. This modality should be considered as a potential therapeutic option in the ED or urgent care setting. (C) 2018 Elsevier Inc. All rights reserved.
