The membrana tympani in health and disease : clinical contributions to the diagnosis and treatment of diseases of the ear, with Supplement . thin cicatrix was thus indicated,so as to admit again the waves .of sound into the cavitythrough the re-established perforation. Therefore Iundertook the operation, upon the 26th of introduced a large hard-rubber speculum intothe external meatus, I illuminated the membrane bymeans of a mirror fastened to spectacle-frames, anddivided the cicatrix in the direction of its longest diame-ter, using the double-edged cataract-needle. The paincaused by the incision was very little. Then a hard-rubber eyelet, having several grooves, was grasped withthe forceps, and pushed through the incision into thecavity of the tympanum to the depth of half a line(Fig. 5). The thin and inelastic cica-trix presented very slight resistance, andthe patient had not the least unpleasantsensation in the ear, either during theintroduction or afterward. Throughthe aperture of the eyelet we could nowsee the pale orange-colored mucous membrane of thepromontory, and the patient stated, without previous. Suj>j)l< iik nf. 179 questioning, that she suddenly heard better, and that thesubjective sounds had considerably abated. After I had convinced myself, by inclining the headof the patient to the left, and severely slinking it, thatthe eyelet was firmly held in the perforation, that, consequently, the edges of the opening were lying in thegrooves, I proceeded to test accurately the hearing dis-tance. The watch, which before could only be perceivedupon contact with the auricle, was now heard at the dis-tance of nine inches. The hearing distance for speechwas only three feet before, but now it had risen to morethan forty (measured at Oppolzers clinic). I was able,repeatedly, to verify this striking improvement during theweeks following, and to-clay, thirty-six days later, thecondition of the membrane is just the same as immedi-ately after the op
