Hermann Schwartze

Last updated April 07, 2019

Hermann Hugo Rudolf Schwartze (7 September 1837 – 20 August 1910) was a German aurist, born at Neuhof in Pomerania and educated in Berlin and Würzburg. He settled in Halle, where he became assistant professor of otology at its university.

Audiology is a branch of science that studies hearing, balance, and related disorders. Audiologists treat those with hearing loss and proactively prevent related damage. By employing various testing strategies, audiologists aim to determine whether someone has normal sensitivity to sounds. If hearing loss is identified, audiologists determine which portions of hearing are affected, to what degree, and where the lesion causing the hearing loss is found. If an audiologist determines that a hearing loss or vestibular abnormality is present he or she will provide recommendations for interventions or rehabilitation.

Pomerania is a historical region on the southern shore of the Baltic Sea in Central Europe, split between Germany and Poland.

Berlin is the capital and largest city of Germany by both area and population. Its 3,748,148 (2018) inhabitants make it the second most populous city proper of the European Union after London. The city is one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with its capital, Potsdam. The two cities are at the center of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of more than 30,000 km², Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions.

One of the founders of modern otology, Schwartze made a particular study of the anatomy of the ear and improved the methods of paracentesis on the tympanic membrane and of the opening of inflamed apophyses of the middle ear.

Otology is a branch of medicine which studies normal and pathological anatomy and physiology of the ear as well as their diseases, diagnosis and treatment. Otologic surgery generally refers to surgery of the middle ear and mastoid related to chronic otitis media, such as tympanoplasty, or ear drum surgery, ossiculoplasty, or surgery of the hearing bones, and mastoidectomy. Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. Neurotology, a related field of medicine and subspecialty of Otolaryngology, is the study of diseases of the inner ear, which can lead to hearing and balance disorders. Neurotologic surgery generally refers to surgery of the inner ear or surgery that involves entering the inner ear with risk to the hearing and balance organs, including labyrinthectomy, cochlear implant surgery, and surgery for tumors of the temporal bone, such as intracanlicular acoustic neuromas. Neurotology is expanded to include surgery of the lateral skull base to treat intracranial tumors related to the ear and surrounding nerve and vascular structures, such as large cerebellar pontine angle acoustic neuromas, glomus jugulare tumors and facial nerve tumors.

Anatomy The study of the structure of organisms and their parts

Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate (embryology) and long (evolution) timescales. Anatomy and physiology, which study (respectively) the structure and function of organisms and their parts, make a natural pair of related disciplines, and they are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine.

Paracentesis is a form of body fluid sampling procedure, generally referring to peritoneocentesis in which the peritoneal cavity is punctured by a needle to sample peritoneal fluid.

He wrote Praktische Beiträge zur Ohrenheilkunde (1864), Pathologische Anatomie des Ohrs (1878; English translation by J. O. Green, The Pathological Anatomy of the Ear, 1878), Lehrbuch der chirurgischen Krankheiten desOhrs (1885), and Grundriss der Otologie (1905). He was co-editor with Emil Berthold of the Handbuch der Ohrenheilkunde (1892–1893); and in 1864 was co-founder of the Archiv für Ohrenheilkunde with Adam Politzer and Anton von Troeltsch. This publication was the first journal in Germany dedicated to ear disorders.

The middle ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear. The mammalian middle ear contains three ossicles, which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear. The hollow space of the middle ear is also known as the tympanic cavity and is surrounded by the tympani bone. The auditory tube joins the tympanic cavity with the nasal cavity (nasopharynx), allowing pressure to equalize between the middle ear and throat.

Dorland's Medical Dictionary (1938)

Schwartze's sign: a reddish-blue discoloration behind the tympanic membrane, occasionally seen in otosclerosis.

Otosclerosis otitis interna characterized by an abnormal bone growth in the middle ear

Otosclerosis is a condition where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth. It can result in hearing loss, tinnitus, vertigo or a combination of symptoms. The term otosclerosis is something of a misnomer. Much of the clinical course is characterized by lucent rather than sclerotic bony changes, so the disease is also known as otospongiosis.

Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process. Cholesteatomas are not cancerous as the name may suggest, but can cause significant problems because of their erosive and expansile properties. This can result in the destruction of the bones of the middle ear (ossicles), as well as growth through the base of the skull into the brain. They often become infected and can result in chronically draining ears. Treatment almost always consists of surgical removal.

The incus or anvil is a bone in the middle ear. The anvil-shaped small bone is one of three ossicles in the middle ear. The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes medially. The incus is so-called because of its resemblance to an anvil.

The oval window is a membrane-covered opening that leads from the middle ear to the vestibule of the inner ear.

In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.

The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex.

A myringotomy, sometimes called by other names, is a surgical procedure in which a tiny incision is created in the eardrum to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube is inserted into the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid. Without the insertion of a tube, the incision usually heals spontaneously in two to three weeks. Depending on the type, the tube is either naturally extruded in 6 to 12 months or removed during a minor procedure.

Ádám Politzer was a Hungarian and Austrian physician and one of the pioneers and founders of otology.

The tympanic part of the temporal bone is a curved plate of bone lying below the squamous part of the temporal bone, in front of the mastoid process, and surrounding the external part of the ear canal.

The anterior tympanic artery is a small artery in the head that supplies the middle ear. It usually arises as a branch of the first part of the maxillary artery. It passes upward behind the temporomandibular articulation, enters the tympanic cavity through the petrotympanic fissure, and ramifies upon the tympanic membrane, forming a vascular circle around the membrane with the stylomastoid branch of the posterior auricular, and anastomosing with the artery of the pterygoid canal and with the caroticotympanic branch from the internal carotid.

In human anatomy, Prussak's Space is the small middle ear recess, bordered laterally by the flaccid part of Shrapnell's membrane, superiorly by the scutum and lateral malleal ligament, inferiorly by the lateral process of the malleus, and medially by the neck of the malleus. From the neck of the malleus, the anterior malleolar fold and the anterior ligament arise, demarcating Prussak's space anteriorly. Ventilation of Prussak's space is only possible posteriorly above the posterior malleus fold.
