    Fig. D. Bone-cyst Due to Ectasia of the Ethmoid Cells, the Frontal Sinus, and the Nasal Cavity.—M. F., carpenter, 24 years old. The tumor first made its appearance seven years ago, above the inner canthus of tlie left eye, and increased gradually, attaining its present size two years ago. No pain at any time; but last winter there was excessive lachryniation from time to time. At present there arc no signs of inflammation and the left lachrymal duct is patulous. The tumor is about the size of a pigeon’s egg, the greater portion situated above the internal lateral ligament, which forms a slight constriction in its lower portion. In the region of the root of the nose it is impossible to differentiate by palpation between the supra- orbital margin and the tumor; but along the u])per outer border the tumor can be felt extending some distance into the orbit. The tumor is tense, elastic, and fluctuating; no pulsation. Crossed diplopia. Visual acuity and fundus normal. Upon extirpation of what was thought to he a dermoid cyst, a fibrous sac of connective tissue was found, which could not be dissected out, being firmly adherent to the bone on its ui)i)er and nasal sides, and limited on the outer side by a thin i)late of hone, the nasal wall of the orbit. The bony plate is displaced toward the orbit and is slightly movable. The .sac contained a mass of thick, greenish or brownish gelatinous material. After this was removed, a cavity the size of a ])igeon’s egg was exposed, communicating above with the frontal sinus and below with the nasal cavity, and limited on the orbital side partly by the plate of bone and partly by connective tissue. Cure was effected in three weeks. The plate of bone and the eyeball gradually assumed a more nasal position. fmjuent b(Miign tumors. Tlio di.sjfo.sition to dermoid evst is congenital, but the growth usually does not develop sufficiently to inconvenience the ])atient until quite late in life. Its favorite seat is the anterior ])ortion of the orbit, a little above either the inner or the outer canthus; but a large cyst may fill the greater part of the orbit and cau.se lateral displacement of the bulb. Care must be excrci.sed not to inci.se the cyst during the ojferation. In excep- tional cases J have done this })urposely, when the cyst was very large and jiartly situated behind the globe. I made a small incision in the anterior polo and closed it again after part of the contents had escaped, so that the cyst, while retaining a moderate degree of tension, was quite easily removed in toto from behind the bulb.
