Otic polyp Otic polyp An otic polyp (also called aural polyp) is a benign proliferation of chronic inflammatory cells associated with granulation tissue, in response to a longstanding inflammatory process of the middle ear. Patients usually present with otorrhea, conductive hearing loss, and otalgia, while bleeding and a sensation of a mass are much less common. Although imaging is not required to yield a diagnosis, it may be obtained to exclude other disorders, such as a concurrent cholesteatoma. By gross description, there is usually a solitary, polypoid, reddish mass behind an intact ear drum (typmanic membrane). The tissue is often friable, measuring
Human body writing the influential book "De humani corporis fabrica". Anatomy advanced further with the invention of the microscope and the study of the cellular structure of tissues and organs. Modern anatomy uses techniques such as magnetic resonance imaging, computed tomography, fluoroscopy and ultrasound imaging to study the body in unprecedented detail. The study of human physiology began with Hippocrates in Ancient Greece, around 420 BC, and with Aristotle (384–322 BC) who applied critical thinking and emphasis on the relationship between structure and function. Galen (c. 126–199) was the first to use experiments to probe the body's functions. The term physiology was
