A new lacrimal neuralgia, a new nerve blockade procedure

Supratrochlear Neuralgia: A Prospective Case Series of 15 Patients

“…The current description of supratrochlear neuralgia completes the spectrum of periorbital neuralgias. Cranial neuralgias that may cause periorbital pain include supraorbital neuralgia, supratrochlear neuralgia, infratrochlear neuralgia, lacrimal neuralgia, and infraorbital neuralgia . While all these disorders are considered trigeminal branch neuralgias, they are distinct from trigeminal neuralgia .…”

Lacrimal Nerve Blocks for Three New Cases of Lacrimal Neuralgia

“…[1][2][3] The main demographic and clinical characteristics of all cases described previously and the three cases reported here are shown in Table 1. It was first described in 2013 1 and only four cases have been communicated so far.…”

“…[1][2][3] The main demographic and clinical characteristics of all cases described previously and the three cases reported here are shown in Table 1. 2,3 This procedure was similar to that recommended for supraorbital nerve blocks in clinical practice, 4,5,17 and is the one we used in our patients. One case was secondary to ophthalmic surgery whereas the remaining cases (n 5 6) were idiopathic.…”

“…Lacrimal neuralgia is a rare disorder clinically characterized by: (1) pain in the territory supplied by the lacrimal nerve at the lateral upper eyelid and/or the adjacent area of the temple, (2) tenderness on palpation of the lacrimal nerve at the superoexternal angle of the orbit, and (3) temporary or persistent pain relief on anesthetic block of the lacrimal nerve. The pain presents with a continuous or intermittent pattern and may be associated with signs and symptoms of sensory dysfunction.…”

“…Three of them were considered primary or idiopathic, 1,2 whereas the last case was attributed to ophthalmic surgery. 2,3 The latter was advocated as a more simple procedure. [4][5][6][7][8][9][10][11] In addition, nerve blocks may have a long-lasting therapeutic effect in some of the patients with lacrimal neuralgia.…”
