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
Joel-Cohen incision for re-appearance of audible intestinal sounds were shorter in Joel-Cohen group than the Pfannenstiel group in a study conducted with 153 women. In the two studies (with 411 participants) that compared the Joel-Cohen incision with the Pfannenstiel incision, the Joel-Cohen incision was associated with a 65% reduction in postoperative febrile morbidity. The skin incision is made 3 cm above the location of Pfannenstiel incision. The subcutaneous tissue is incised in three medial centimetres. The lateral tissue separation is done manually and the fascia is divided by blunt dissection using both index fingers. This incision is extended laterally by the fingers.
