Heinrich Adolf Rinne
Heinrich Adolf Rinne (January 24, 1819 – July 26, 1868) was a German otologist born in Vlotho an der Weser. He received his doctorate from the University of Göttingen and practiced medicine in the city of Göttingen. Later he was a physician in Sandstadt near Stade (1857) and Hildesheim (1860). In 1855 Rinne described the combined conductive process of the tympanic membrane and the ossicles of the middle ear. He is known for the eponymous Rinne test. The Rinne test is a hearing test conducted with a tuning fork, and is used to test and compare a patients' hearing via air conduction (normal process) or by way of bone conduction (sound to the inner ear through the mastoid). He reasoned that if a person hears a sound for a longer period of time through bone conduction than through air conduction, a disease is present somewhere in the conduction apparatus. Despite his research, "Rinne's test" wasn't generally recognized until after his death — in the early 1880s, otologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mastoid
The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones. Etymology The word "mastoid" is derived from the Greek word for "breast", a reference to the shape of this bone. Surfaces Outer surface Its outer surface is rough and gives attachment to the occipitalis and posterior auricular muscles. It is perforated by numerous foramina (holes); for example, the mastoid foramen is situated near the posterior border and transmits a vein to the transverse sinus and a small branch of the occipital artery to the dura mater. The position and size of this foramen are very variable; it is not always present; sometimes it is situated in the occipital bone, or in the suture between the temporal and the occipital. Mastoid process The mastoid process is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernst Heinrich Weber
Ernst Heinrich Weber (24 June 1795 – 26 January 1878) was a German physician who is considered one of the founders of experimental psychology. He was an influential and important figure in the areas of physiology and psychology during his lifetime and beyond. His studies on sensation and touch, along with his emphasis on good experimental techniques led to new directions and areas of study for future psychologists, physiologists, and anatomists. Ernst Weber was born into an academic background, with his father serving as a professor at the University of Wittenberg. Weber became a doctor, specializing in anatomy and physiology. Two of his younger brothers, Wilhelm and Eduard, were also influential in academia, both as scientists with one specializing in physics and the other in anatomy. Ernst became a lecturer and a professor at the University of Leipzig and stayed there until his retirement. Early life Ernst Heinrich Weber was born on 24 June 1795 in Wittenberg, Saxony, Holy ...

August Lucae
Johann Constantin August Lucae (24 August 1835 – 17 March 1911) was a German otologist who was a native of Berlin. He studied medicine in Berlin and Bonn, and in 1859 earned his doctorate. He furthered his studies in London with Joseph Toynbee (1815–1866), later returning to Berlin, where he worked in Virchow's pathological institute. In 1871 he became an associate professor, and in 1874 was appointed director of the university policlinic for ear diseases. In 1899 Lucae became a full professor of otology at the University of Berlin. Lucae made numerous contributions in the field of otology, being remembered for his pioneer studies involving the transmission of sound via bone conduction for diagnosis of ear disease. He is credited with introducing an "interference otoscope", an apparatus he developed to determine the relative amount of reflection from both ears. His name is associated with several instruments used in otology, including the "Lucae pressure probe", a de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
