Ádám Politzer
Ádám Politzer (; 1 October 1835, Albertirsa, Pest, Hungary – 10 August 1920, in Vienna) was a Hungarian and Austrian physician and one of the pioneers and founders of otology. Life Ádám Politzer was born in Alberti (now part of Albertirsa), near the city of Budapest, to a well-to-do Jewish family. He studied medicine in the University of Vienna. Some of his teachers belonged to the Second " Vienna School", including Carl Freiherr von Rokitansky (1804–1878) and Josef Skoda (1805–1881) (its founders), as well as Joseph Hyrtl (1810–1894), Johann Ritter von Oppolzer (1808–1871), and the physiologist Carl Ludwig (1816–1895). The last two took interest in Politzer and were influential in his subsequent career. Politzer received his M.D. in 1859 and started to work in Carl Ludwig's laboratory. His interest since that time was mainly the physics of the auditory system. There, he was the first to demonstrate physiologically that the innervation of the tensor tympan ...

Doctor Of Medicine
A Doctor of Medicine (abbreviated MD, from the Latin language, Latin ) is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the ''MD'' denotes a professional degree of physician. This generally arose because many in 18th-century medical professions trained in Scotland, which used the MD degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery (MBBS) was used: in the 19th century, it became the standard in Scotland too. Thus, in the United Kingdom, Republic of Ireland, Ireland and other countries, the MD is a research doctorate, honorary degree, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others' usage of MD is still typically titled Bachelor of Medicine, Bachelor of Surgery. History The fi ...

Politzerization
Politzerization, also called the Politzer maneuver or method, is a medical procedure that involves inflating the middle ear by blowing air up the nose during the act of swallowing. It is often performed to reopen the Eustachian tube and equalise pressure in the middle ear. The procedure was derived from a medical experiment first performed by Ádám Politzer of Vienna that involved studying the air movement through the Eustachian tube by connecting a manometer to the external auditory canal meatus and another manometer in the pharynx. His first results on the technique were published in 1861 and he introduced a pear-shaped rubber air-bag for performing the procedure in 1863, which came to be known as a Politzer bag. This system was far more practical and less difficult for the patient than catheterizing the Eustachian tube and brought fame to Politzer. Use in clinical devices One device that utilizes Politzeration is the EarPopper, developed by Shlomo Silman, Ph.D., profes ...

Catheter
In medicine, a catheter ( ) is a thin tubing (material), tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. Catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular and ophthalmic procedures. The process of inserting a catheter is called ''catheterization''. In most uses, a catheter is a thin, flexible tube (''soft'' catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a "permcath" (originally a trademark). Catheters can be inserted into a body cavity, duct, or vessel, brain, skin or adipose tissue.

Ear Diseases
In vertebrates, an ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In humans, the ear is described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the auricle and the ear canal. Since the outer ear is the only visible portion of the ear, the word "ear" often refers to the external part (auricle) alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ear canal is cleaned via earwax, which naturally migrates to the auricle. The ear develops from the first pharyngeal pouch and six small swellings that develop in the early embryo called otic placodes, which are derived from the e ...
