Oral and Maxillofacial Surgeons This group considers that there are a number of primary forms of [[mandibular hypoplasia]] most commonly being [[anterior mandibular hypoplasia]], [[posterior mandibular hypoplasia]], and [[agenia]], each of which offer a primary anatomical basis to the development of OSA through the condition called [[gllosoptosis]].
Obese people show an increase in neck fat tissue which potentiate respiratory obstruction during sleep. It is speculated that they may have increased muscle mass, or alternatively have a tendency to decreased muscle tone potentiating airway collapse during sleep.
However loss of muscle tone is a key feature of deep sleep anyway, and whilst obesity seems a common association, it is not an invariable state of OSA. Sleeping supine on the back is also represented as a risk factor for OSA.
Clearly gravity, and loss of tongue and throat tone as a person enters deep sleep are clear and obvious factors contributing to OSA developing. But this explanation is also confounded by the presence of neck obesity.

Throat lesions, particularly enlarged tonsils, are well recognised as aggravators of OSA, and removal may provide full or partial or semi permanent relief from OSA Of substantial recent interest is the idea that there is a general human tendency towards developing short lower jaws neoteny is a major cause of OSA through a combined condition called Glossoptosis. In much the same way, a narrow upper jaw will also contribute to OSA due to it's relation to airway volume. A more narrow upper jaw results in more narrow nasal passages and a more narrow throat, this also appears to be why so many OSA patients experience nasal congestion especially while laying down.
Maxillofacial Surgeons see many effects of small lower jaws, including crowded teeth, malocclusions, as well as OSA - all cpap súlycsökkenést okoz which are treatable by surgical operations that increase and normalise jaw size. Risk factors[ edit ] Old age is often accompanied by muscular and neurological loss of muscle tone of the upper airway. Decreased muscle tone is also temporarily caused by chemical depressants; alcoholic drinks and sedative medications being the most cpap súlycsökkenést okoz.
Permanent premature muscular tonal loss in the upper airway cpap súlycsökkenést okoz be precipitated by traumatic brain injuryneuromuscular disordersor poor adherence to chemical cpap súlycsökkenést okoz or speech therapy treatments. Individuals with decreased muscle tone and increased soft tissue around the airway, and structural features that give rise to a narrowed airway are at high risk for OSA.
Men, in which the anatomy is typified by increased mass in the torso and neck, are at increased risk of developing sleep apnea, especially through middle age and later. 290 font súlycsökkenés suffer typically less frequently and to a lesser degree than do men, owing partially to physiology, but possibly also to differential levels of progesterone. Prevalence in post-menopausal women approaches that of men cpap súlycsökkenést okoz the same age range.
Women are at greater risk for developing OSA during pregnancy. Lifestyle factors such as smoking may also increase the chances of developing OSA as the chemical irritants in smoke tend to inflame the soft tissue of the upper airway and promote fluid retention, both of which can result in narrowing of the upper airway.
Cigarette may also have an impact due to a decline of blood nicotine levels, which alters sleep stability. Some of these craniofacial syndromes are genetic, others are from unknown causes. In many craniofacial syndromes, the features súlyvesztés policisztás petefészek szindrómával are unusual involve the nose, mouth, and jaw, or resting muscle tone, and put the individual at risk for OSA syndrome.
Down syndrome is one such syndrome. In this chromosomal abnormality, several features combine to make the presence of obstructive sleep apnea more likely. The specific features of Down syndrome that predispose to obstructive sleep apnea include relatively low muscle tone, narrow nasopharynxand large tongue. Obesity and enlarged tonsils and adenoids, conditions that occur commonly in the western population, are much more likely to be obstructive in a person with these features than without them.

Obstructive sleep apnea does occur even more frequently in people with Down syndrome than in the general population. Cleft palate syndromes are such an example. During the newborn period, all humans are obligate nasal breathers. The palate is both the roof of the mouth and the floor of the nose.
Having an open palate may make feeding difficult, but generally, does not interfere with breathing, in fact, if the nose is very obstructed, then an open palate may relieve breathing. There are a number of clefting syndromes in which the open palate is not the only abnormal feature; additionally, there is a narrow nasal passage - which may not be obvious.
Obstructive sleep apnea
In such individuals, closure of the cleft palate — whether by surgery or by a temporary oral appliance, can cause the onset of obstruction. Skeletal advancement in an effort to physically increase the pharyngeal airspace is often an option for craniofacial patients with upper airway obstruction and small lower jaws mandibles. These syndromes include Treacher Collins syndrome and Pierre Robin sequence.
Mandibular advancement surgery is one of the modifications needed to improve the airway, others may include reduction of the tongue, tonsillectomy or modified uvulopalatoplasty. Following pharyngeal flap surgery, depending on size and position, the flap itself may have an " obturator " or obstructive effect within the pharynx during sleep, blocking ports of airflow and hindering effective respiration.
Obstructive sleep apnea - Wikipedia
When velopalatal insufficiency is present, air leaks into the nasopharynx even when the soft palate should close off the nose. A simple test for this condition can be made by placing a tiny mirror on the nose, and asking the egészséges fogyás 8 hónap alatt to say "P". This p sound, a plosive, is normally produced with the nasal airway closes off - all air comes out of the pursed lips, none from the nose.
If it is impossible to say the sound without fogging a nasal mirror, there max fogyás hét an air leak - reasonable evidence of poor palatal closure. Speech is often unclear due to inability to pronounce certain sounds.

One of the surgical treatments for velopalatal insufficiency involves tailoring the tissue from the back of the throat and using it to purposefully cause partial obstruction of the opening of the nasopharynx. This may actually cause OSA syndrome in susceptible individuals, particularly in the days following surgery, when swelling occurs see below: Special Situation: Anesthesia and Surgery. Guidelines intended to reduce the risk of perioperative complications have been published. However, once the SDB is treated, the hyperactive behavior can improve, and the treatment can be stopped.
However, the condition still has effects on the brain and can lead to adverse neurocognitive and behavioral sequelae. It is particularly concerning as those consequences happen while the brain cpap súlycsökkenést okoz still developing. This study allowed to see the overall impact of OSA on learning abilities associated with language or numeracy skills, and physical development.

The deficits in school performance can nevertheless be improved if adenotonsillectomy is performed on children to treat the OSA.
The variability of the blood pressure has been shown to be correlated with the severity of the symptoms such as the frequency of the apnea and hypopnea. Obesity interact with those effects.
The interaction between Cpap súlycsökkenést okoz and obesity might thus result in nocturnal enuresis. Adenotonsillectomy can decrease the intensity of the depressive symptoms.
While meta-analysis have shown no deficits in retention of information for patients with OSA, those impairment in verbal memory may be linked to problems in encoding information.
Those conditions may lead to increased mortality   that an appropriate treatment for OSA may reduce. The OSA-related hypercapnia has been suggested to be related to this development of hypertension.
CPAP therapy can lead to an improvement of some of the cardiovascular component of the metabolic syndrome  while weight loss is also recommended for its positive effects on OSA consequences and metabolic dysfunctions. Nasal obstruction can thus aggravate the psychological health of OSA patients. Nasal surgery for those patients might decrease the OSA severity and improve the psychological symptoms. If reductions in ventilation are associated with sufficiently low blood oxygen levels or with sufficiently high breathing efforts against an obstructed airway, neurological mechanisms may trigger a sudden interruption of sleep, called a neurological arousal.
