Patulous Eustachian tube is the name of a physical disorder where the Eustachian tube, which is normally closed, instead stays intermittently open. When this occurs, the person experiences autophony, the hearing of self-generated sounds. [1] These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and ...
The "Toynbee maneuver": pinching the nose and swallowing. Swallowing pulls open the eustachian tubes while the movement of the tongue, with the nose closed, compresses air which passes through the tubes to the middle ear. The "Valsalva maneuver": pinching the nose and closing the mouth and trying to breathe out through the nose.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
The two wax rims are then notched in order to allow an index of the relationship of the maxillary rim to the mandibular rim with a medium, such as Alluwax or Regisal. Vertical dimension of occlusion, or VDO, also known as occlusal vertical dimension (OVD), is a term used in dentistry to indicate the superior-inferior relationship of the maxilla ...
An OAC is an abnormal physical communication between the maxillary sinus and the mouth. This opening is only present when the structures that normally separates the mouth and sinus into 2 separate compartments are lost. There are many causes of an OAC.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species.
Obligate nasal breathing describes a physiological instinct to breathe through the nose (or other forms of external nasal passages, depending on the species) as opposed to breathing through the mouth.
The Eustachian tube ( / juːˈsteɪʃən / ), also called the auditory tube or pharyngotympanic tube, [1] is a tube that links the nasopharynx to the middle ear, of which it is also a part. In adult humans, the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter. [2] It is named after the sixteenth-century ...
The nasal mucosa lines the nasal cavity. It is part of the respiratory mucosa, the mucous membrane lining the respiratory tract. [1] [2] The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the ...
Treatment of the underlying cause of nasal congestion if present, building a habit to breathe through the nose. Mouth breathing, medically known as chronic oral ventilation, is long-term breathing through the mouth. It often is caused by an obstruction to breathing through the nose, the innate breathing organ in the human body.
