Terrier, Guillemain, and Malherbe, in their “Chirurgie du Cou,” 1898, were among the first to give the surgery of the sympathetic a place in a text-book. Among those who have operated on the cervical sympathetic for the relief either of glaucoma or exophthalmic goiter, or both, are Abadie, Réclus, Gerard-Marchant, Chauffand and Quénu, Jeunet, Bled, Ball, Renaud, and Bartlett. Panas is opposed to sympathectomy in glaucoma. He reports seeing a patient in whom, three months after the operation, vision was still declining. François-Frank, at a meeting of the Paris Academy of Medicine, held May 22, 1899, spoke of the effect of sympathectomy on the circulation of the thyroid gland, brain, and eyes, and on the heart. He believes that the operation can easily produce good results. Doyon has described the trophic changes produced in the rabbit by excision of the cervical sympathetic. CONCLUSIONS. From a study of the cases of sympathectomy made by Jonnesco and others, and from the observation of my own cases, I offer these conclusions: 1. Excision of the superior cervical ganglion is a most valuable procedure in glaucoma. 2. It is of more value in glaucoma simplex than in inflammatory glaucoma. 3. In inflammatory glaucoma, on which iridectomy has been done without benefit, excision of the superior cervical ganglion should certainly be tried. 4. In cases of absolute glaucoma with pain, sympathectomy is to be tried before resorting to any operation on the eyeball. 5. In cases of simple optic-nerve atrophy, sympathectomy may possibly be beneficial if done before vision is entirely lost. 6. In cases of exophthalmic goiter, which do not improve under hygienic medicinal and electric treatment, excision of the cervical sympathetic on both sides is to be advised. 7. In unilateral glaucoma excision of the sympathetic ganglion is to be done only on the corresponding side. 8. In the hands of a careful operator, excision of the superior and middle ganglia is a safe operation, but removal of the inferior ganglion can be done safely only by the most skillful surgeons. 9. The postmastoid route is to be preferred in excision of any part, or all of the cervical sympathetic. 10. The fact that glaucoma is improved by sympathectomy and the finding of pathologic changes in the excised ganglia suggest the conclusion that this affection is due either to a permanent irritation of the cervical sympathetic, or to an irritation located elsewhere and transmitted by means of the cervical sympathetic. I wish to extend my thanks to Drs. E. C. Renaud and Willard Bartlett for valuable assistance in the preparation of this paper; to Dr. Carl Fisch for the pathologic report. DEADY. =Heath, M.
