Uvulopalatopharyngoplasty
Uvulopalatopharyngoplasty (abbreviated as UPPP or UP3) is a type of sleep surgery, which are surgical procedures for sleep-related breathing disorders, especially obstructive sleep apnea (OSA). Uvulopalatopharyngoplasty involves removal and/or remodeling of tissues in the throat in order to prevent obstruction of the airway during sleep. Tissues which may typically be removed include the paryngeal tonsils and the adenoid tonsil. Tissues which may typically be remodeled include the uvula (see uvulotomy), the soft palate, and parts of the pharynx. UPPP is the most common surgical procedure performed for OSA. Background OSA is one of the most common types of sleep-related breathing disorder. It involves obstruction of the upper airway during sleep. Loud snoring and apnea (periods of no breathing) followed by gasping and choking are signs of the condition. The main treatment is continuous positive airway pressure and a range of other measures such sleeping on the side and mandibular a ...

Sleep Surgery
Sleep surgery is a range of surgical procedures to treat sleep-related breathing disorders (sleep-disordered breathing), especially obstructive sleep apnea (OSA). The spectrum of sleep-related breathing disorders also includes Snoring, primary snoring (non apneic snoring), upper airway resistance syndrome, and obesity hypoventilation syndrome. These surgeries are performed by surgeons trained in otolaryngology, oral maxillofacial surgery, and craniofacial surgery. Background Obstructive sleep apnea (OSA) is defined as either cessation of breathing (apnea) for 10 seconds, or a decrease in normal breathing (hypopnea) with an associated desaturation in oxygen and arousal during sleep that lasts at least 10 seconds. In adults, it is typical to have up to 4.9 events per hour. In OSA, affected individuals are categorized based on how many apneas or hypopneas (apnea-hypopnea index or AHI) or events they have per hour. * Normal: <5 events per hour * Mild: 5 to <15 events per hour * M ...

Obstructive Sleep Apnea
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial airway obstruction, obstruction of the respiratory tract#Upper respiratory tract, upper airway leading to reduced or absent breathing during sleep. These episodes are termed "apneas" with complete or near-complete cessation of breathing, or "hypopneas" when the reduction in breathing is partial. In either case, a fall in oxygen saturation (medicine), blood oxygen saturation, a disruption in sleep, or both, may result. A high frequency of apneas or hypopneas during sleep may interfere with the quality of sleep, whichin combination with disturbances in blood oxygenationis thought to contribute to negative consequences to health and quality of life. The terms obstructive sleep apnea syndrome (OSAS) or obstructive sleep apnea–hypopnea syndrome (OSAHS) may be used to refer to OSA when it is associated with symptoms during the daytime (e.g. ...

Uvula
The uvula (: uvulas or uvulae), also known as the palatine uvula or staphyle, is a conic projection from the back edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers. It also contains many serous glands, which produce thin saliva. It is only found in humans. Structure Muscle The muscular part of the uvula () shortens and broadens the uvula. This changes the contour of the posterior part of the soft palate. This change in contour allows the soft palate to adapt closely to the posterior pharyngeal wall to help close the nasopharynx during swallowing. Its muscles are controlled by the pharyngeal branch of the vagus nerve. Variation A bifid or bifurcated uvula is a split or cleft uvula. Newborns with cleft palate often also have a split uvula. The bifid uvula results from incomplete fusion of the palatine shelves but it is considered only a slight form of clefting. Bifid uvulas have les ...

Velopharyngeal Insufficiency
Velopharyngeal insufficiency is a disorder of structure that causes a failure of the velum (soft palate) to close against the posterior Pharynx, pharyngeal wall (back wall of the throat) during speech in order to close off the nasal cavity during oral speech production. This is important because speech requires sound from the vocal folds and airflow from the lungs to be directed into the oral cavity (mouth) for the production of all Phone (phonetics), speech sounds, with the exception of nasal consonants (m, n, and ng). If complete closure does not occur during speech, this can cause Hypernasal speech, hypernasality (a resonance disorder) and/or audible nasal emission during speech (a speech sound disorder). In addition, there may be inadequate airflow to produce most consonants, making them sound weak or omitted. The terms "velopharyngeal insufficiency", "velopharyngeal incompetence", "velopharyngeal inadequacy", and "velopharyngeal dysfunction" have often been used interchangea ...

Globus Pharyngis
Globus pharyngeus (also termed globus sensation) is the persistent but painless sensation of having a pill, food bolus, or some other sort of obstruction in the throat when there is none. Swallowing is typically performed normally, so it is not a true case of dysphagia, but it can become quite irritating. It is common, with 22–45% of people experiencing it at least once in their lifetime. Causes The "lump in the throat" sensation that characterizes globus pharyngis is often caused by inflammation of one or more parts of the throat, such as the larynx or hypopharynx, due to cricopharyngeal spasm, gastroesophageal reflux (GERD), or laryngopharyngeal reflux. In some cases the cause is unknown and symptoms may be attributed to a psychogenic cause ''i.e.'' a somatoform or anxiety disorder. It has been recognised as a symptom of depression, which responds to anti-depressive treatment. The results of recent studies have strongly suggested that GERD is a major cause of globus, tho ...

Dysgeusia
Dysgeusia, also known as parageusia, is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity. An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom. The distortion in the sense of taste is the only symptom, and diagnosis is usually complicated since the sense of taste is tied together with other sensory systems. Common causes of dysgeusia include chemotherapy, asthma treatment with albuterol, and zinc deficiency. Liver disease, hypothyroidism, and rarely, certain types of seizures can also lead to dysgeusia. Different drugs can also be responsible for altering taste and resulting in dysgeusia. Due to the variety of causes of dysgeusia, there are many possible treatments that are effective in alleviating or terminating the symptoms. These include artificial saliva, pilocarpine, zinc supplementat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dysphagia
Dysphagia is difficulty in swallowing. Although classified under " symptoms and signs" in ICD-10, in some contexts it is classified as a condition in its own right. It may be a sensation that suggests difficulty in the passage of solids or liquids from the mouth to the stomach, a lack of pharyngeal sensation or various other inadequacies of the swallowing mechanism. Dysphagia is distinguished from other symptoms including odynophagia, which is defined as painful swallowing, and globus, which is the sensation of a lump in the throat. A person can have dysphagia without odynophagia (dysfunction without pain), odynophagia without dysphagia (pain without dysfunction) or both together. A psychogenic dysphagia is known as phagophobia. Classification Dysphagia is classified into the following major types: # Oropharyngeal dysphagia # Esophageal and obstructive dysphagia # Neuromuscular symptom complexes # Functional dysphagia is defined in some patients as having no organic c ...

Dehydration
In physiology, dehydration is a lack of total body water that disrupts metabolic processes. It occurs when free water loss exceeds intake, often resulting from excessive sweating, health conditions, or inadequate consumption of water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over 10% of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs with a 15 and 25% loss of body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration usually resolves with oral rehydration, but severe cases may need intravenous fluids. Dehydration can cause hypernatremia (high levels of sodium ions in the blood). This is distinct from hypovolemia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Negative-pressure Pulmonary Edema
Negative-pressure pulmonary edema (NPPE), also known as Postobstructive Pulmonary Edema, is a clinical phenomenon that results from the generation of large negative pressures in the airways during attempted inspiration against some form of obstruction of the upper airways. The most common reported cause of NPPE reported in adults is laryngospasm, while the most implicated causes in children are infectious croup and epiglottitis. The large negative pressures created in the airways by inhalation against an upper airway obstruction can lead to fluid being drawn from blood vessels supplying the lungs into the Alveolus, alveoli, causing pulmonary edema and impaired ability for oxygen exchange (hypoxemia). The main treatment for NPPE is supportive care in an intensive care unit and can be fatal without intervention. Physiology NPPE develops as a result of significant negative pressure generated in the chest cavity by inspiration against an upper airway obstruction. These negative press ...
