Farther observations on the effects which take place from the destruction of the membrana tympani of the ear : with an account of an operation for the removal of a particular species of deafness

The accomplished English surgeon, Sir Astley Paston Cooper (1768-1841), noticed clinically that a hole in the tympanic membrane did not necessarily cause deafness, and that an incision in the anterior-inferior portion of the tympanic membrane could treat hearing loss due to Eustachian tube obstruction. For this procedure, he devised a special trocar and cannula to do the puncture. Cooper reported his cases and findings in this article read before the Royal Society of London on June 25, 1801.
