Myringotomy cleaning it with an ear spoon. Surprisingly, the patient's hearing improved. There are also reports from the 17th and 18th centuries describing separate experiments exploring the function of the ear drum. In particular, the animal experiments of Thomas Willis were expanded upon by Sir Astley Cooper, who presented two papers to the Royal Society in 1801 on his observations that myringotomy could improve hearing. First, he showed that two patients with perforations of both eardrums could hear perfectly well, despite conventional wisdom that this would result in deafness. Second, he demonstrated that deafness caused by obstruction of the Eustachian tube
Body part as an object Body part as an object Body part as an object (BPO) mime gestures occurs when a mime artist or other individual substitutes a part of their body - usually arms, fingers, or hands - to be part of an object they are miming.
