[History of Trigeminal Neuralgia:Before the Era of Modern Treatment]

Descriptions of what appears to be trigeminal neuralgia(TN)appear in medical literature from around the 2nd century AD. Aretaeus of Cappadocia is believed to be the first person in history to have specifically described TN. TN or TN-like facial pain was once known as Fothergill's disease, following a detailed description of the symptoms by Fothergill in the 18th century. For a long time, no effective oral therapy for TN was available, and only surgical treatments were used, such as severing of the trigeminal nerve or resection of the Gasserian ganglion. In the 19th and 20th centuries, Hartley, Krauss, Cushing, Spiller and Frazier developed techniques for approaching the Gasserian ganglion through the middle cranial fossa, and Dandy pioneered trigeminal nerve transection through the posterior fossa. Also at this time, Harris introduced nerve block using alcohol. Later, various oral medications, such as phenytoin(1942)and carbamazepine(1962), were introduced and these became effective treatments. Modern surgical treatment began in the mid-20th century, when Taarnhøj, Gardner and Jannetta introduced nerve decompression.
