Cauliflower Ear
Cauliflower ear is an irreversible condition that occurs when the Auricle (anatomy), external portion of the ear is hit and develops a Thrombus, blood clot or other collection of fluid under the perichondrium. This separates the cartilage from the overlying perichondrium that supplies its nutrients, causing it to die and resulting in the formation of fibrous tissue in the overlying skin. As a result, the outer ear becomes permanently swollen and deformed, resembling a cauliflower, hence the name. The condition is common in wrestling, boxing, and kickboxing, in martial arts such as Brazilian jiu-jitsu, judo, sumo, and mixed martial arts, and in full-contact sports such as rugby union. Presentation People presenting with possible auricular hematoma often have additional injuries (for example, head/neck lacerations) due to the frequently traumatic causes of auricular hematoma. The ear itself is often tense, fluctuant, and tender with throbbing pain. However, because of potentially m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otorhinolaryngology
Otorhinolaryngology ( , abbreviated ORL and also known as otolaryngology, otolaryngology–head and neck surgery (ORL–H&N or OHNS), or ear, nose, and throat (ENT)) is a surgical subspecialty within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians. Patients seek treatment from an otorhinolaryngologist for diseases of the ear, Human nose, nose, throat, base of skull, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face, scalp, and neck. Etymology The term is a combination of Neo-Latin classic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headgear (martial Arts)
Headgear is a padded helmet worn during sparring in the martial arts. Boxing Headgear is a padded helmet, worn on the head by contestants in Amateur and Olympic boxing. It effectively protects against cuts, scrapes, and swelling, but it does not protect very well against concussions. It will not protect the brain from the jarring that occurs when the head is struck. Also, most boxers aim for the chin on opponents, and the chin is usually not protected by headgear. There are different types of boxing headgear available. Some headgear is open-faced. This is the style normally used in amateur boxing competitions. Unlike open-faced headgear, training headgear covers the cheek. "Face-saver" headgear features a pad across the face so that no direct contact is made to the face. As the amount of padding in headgear is increased, visibility is reduced. Usage mandates In 1984, the International Boxing Association (AIBA) began to mandate the use of headguards in all amateur matches ...

Scrum Cap
The scrum cap is a form of headgear used by Rugby football, rugby players to protect the ears in the scrum (rugby), scrum, which can otherwise suffer injuries leading to the condition commonly known as cauliflower ears. Although originally designed for forwards they are now worn by players of all positions, even those who do not play in the scrum. A simpler alternative to a cap, or a head-cap and used by many players, is a thin strip of foam or cloth and electrical tape wrapped around the ears like a head band. Construction The scrum cap was first used by the Christ's College Finchley's 1st XV, and Eurig Evans is credited with its design. The traditional scrum cap was constructed of a thin cloth helmet with padding over the ears, held in place by a strap—but modern models are typically made from thin foam. The headgear is defined by Regulation 12 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meatus Acusticus Externus
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about in length and in diameter. Structure The human ear canal is divided into two parts. The elastic cartilage part forms the outer third of the canal; its anterior and lower wall are cartilaginous, whereas its superior and back wall are fibrous. The cartilage is the continuation of the cartilage framework of auricle. The cartilaginous portion of the ear canal contains small hairs and specialized sweat glands, called apocrine glands, which produce cerumen (ear wax). The bony part forms the inner two thirds. The bony part is much shorter in children and is only a ring (''annulus tympanicus'') in the newborn. The layer of epithelium encompassing the bony portion of the ear canal is much thinner and therefore, more sensitive in comparison to the cartilaginous portion. Size and ...

Ischemia
Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue, i.e., hypoxia and microvascular dysfunction. It also implies local hypoxia in a part of a body resulting from constriction (such as vasoconstriction, thrombosis, or embolism). Ischemia causes not only insufficiency of oxygen but also reduced availability of nutrients and inadequate removal of metabolic wastes. Ischemia can be partial (poor perfusion) or total blockage. The inadequate delivery of oxygenated blood to the organs must be resolved either by treating the cause of the inadequate delivery or reducing the oxygen demand of the system that needs it. For example, patients with myocardial ischemia have a decreased blood flow to the heart and are prescribe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheumatologic
Rheumatology () is a branch of medicine devoted to the diagnosis and management of disorders whose common feature is inflammation in the bones, muscles, joints, and internal organs. Rheumatology covers more than 100 different complex diseases, collectively known as rheumatic diseases, which includes many forms of arthritis as well as lupus and Sjögren syndrome, Sjögren's syndrome. Physician, Doctors who have undergone formal training in rheumatology are called rheumatologists. Many of these diseases are now known to be disorders of the immune system, and rheumatology has significant overlap with immunology, the branch of medicine that studies the immune system. Rheumatologist A rheumatologist is a physician who specializes in the field of medical sub-specialty called rheumatology. A rheumatologist holds a board certification after specialized training. In the United States, training in this field requires four years of undergraduate school, four years of medical school, a ...

Relapsing Polychondritis
Relapsing polychondritis is a systemic disease characterized by repeated episodes of inflammation and in some cases deterioration of cartilage. The disease can be life-threatening if the respiratory tract, heart valves, or blood vessels are affected. The exact mechanism is poorly understood. The diagnosis is reached on the basis of the symptoms and supported by investigations such as blood tests and sometimes other investigations. Treatment may involve symptomatic treatment with painkillers or anti-inflammatory medications, and more severe cases may require suppression of the immune system. Signs and symptoms Though any cartilage in the body may be affected in persons with relapsing polychondritis, in many cases the disease affects several areas while sparing others. The disease may be variable in its signs and symptoms, resulting in a difficult diagnosis which may leads to delayed recognition for several months, years or decades. Associated diseases There are several other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antitragus
The antitragus is a feature of mammalian ear anatomy. In humans, it is a small Tubercle (anatomy)#Ears, tubercle on the visible part of the ear, the Auricle (anatomy), auricle. The antitragus is located just above the earlobe and points anatomical terms of location#Anterior and posterior, anteriorly. It is separated from the Tragus (ear), tragus by the intertragic notch. The antitragicus, antitragicus muscle, an Intrinsic muscles of external ear, intrinsic muscle of the ear, arises from the outer part of the antitragus. The antitragus can be much larger in some other species, most notably bats. The antitragus can be pierced.

Tragus (ear)
The tragus is a small pointed eminence of the external ear, situated in front of the Pinna (anatomy), concha, and projecting backward over the external acoustic meatus, meatus. It also is the name of hair growing at the entrance of the ear. Its name comes from the Ancient Greek (), meaning 'goat', and is descriptive of its general covering on its under surface with a tuft of hair, resembling a goat's beard. The nearby antitragus projects forwards and upwards. Because the tragus faces rearwards, it aids in collecting sounds from behind. These sounds are delayed more than sounds arriving from the front, assisting the brain to sense front vs. rear sound sources. In a positive fistula test (for the presence of a fistula from cholesteatoma to the Inner ear, labyrinth), pressure on the tragus causes vertigo or eye deviation by inducing movement of perilymph. Other animals The tragus is a key feature in many bat species. As a piece of skin in front of the ear canal, it plays an import ...

Antihelix
The antihelix (anthelix) is a part of the visible ear; the pinna. The antihelix is a curved prominence of cartilage parallel with and in front of the helix on the pinna. The antihelix divides above into two ''legs'' or crura; the ''crura antihelicis'', between which is a triangular depression, the ''fossa triangularis''.
