Sleep Apnea

Sleep apnea is a common sleep disorder that involves repeated breathing interruptions during sleep. These interruptions may occur hundred of times each night, and may be the result of structural abnormalities or brain malfunctions. During normal breathing, air passes through the nose, past the flexible structures in the back of the throat, including the soft palate, uvula and tongue. When a person is awake, the muscles hold this airway open. When they are asleep, these muscles relax and the airway usually stays open. Sleep apnea occurs when the upper airway and airflow are blocked, causing the oxygen levels to drop in both in the brain and the blood, resulting in shallow breathing or breathing pauses during sleep.

Causes of Sleep Apnea

Sleep apnea occurs as a result of a partial or fully blocked airway passage in the throat. Certain factors may put certain people at risk for developing sleep apnea, which include:

  • Enlarged tonsils or adenoids
  • Obesity
  • Cardiovascular problems
  • Smoking
  • Family history
  • Nasal congestion
  • Throat and tongue muscles that are more relaxed than normal

Adults over the age of 60 may be more at risk of developing sleep apnea because the aging process may limit the brain's ability to keep the throat muscles stiff during sleep. Heavy use of alcohol or sedatives may also contribute to sleep apnea because these substances may relax the muscles of the throat.

Types of Sleep Apnea

There are different types of sleep apnea that have different causes.

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is the most common form of sleep apnea. It occurs when the soft tissue at the back of the throat closes, blocking or obstructing the airway.

Central Sleep Apnea

In patients with central sleep apnea the airway remains open but the brain does not send signals to the muscles involved in breathing. Patients with heart-related conditions may suffer from central sleep apnea.

Mixed Sleep Apnea

Mixed sleep apnea combines aspects of the obstructive and central types of apnea. A common warning sign of mixed sleep apnea is snoring, especially interspersed with gasps or lack of breathing.

Patients who are overweight, have high blood pressure, are older, smoke or have a family history of sleep apnea may have an increased risk of developing obstructive sleep apnea, while those with heart disease or a stroke are at an increased risk for central sleep apnea.

Symptoms of Sleep Apnea

Patients with sleep apnea may wake up with a headache in the morning and experience excessive daytime sleepiness. Additional symptoms may include:

  • Loud snoring
  • Waking up with a dry mouth or sore throat
  • Insomnia
  • Abrupt awakenings during the night

Individuals with sleep apnea may experience shortness of breath that awakens them from sleep.

Diagnosis of Sleep Apnea

Sleep apnea is diagnosed through a physical examination and a review of symptoms. Individuals may be referred to a sleep specialist who performs various diagnostic tests to confirm a diagnosis of sleep apnea or another sleep disorder. Some evaluations often involve overnight monitoring of breathing and other body functions during sleep. Additional diagnostic tests may include home sleep tests and a nocturnal polysomnography, which monitors heart and lung function, brain activity, breathing patterns, and blood oxygen levels during sleep.

Treatment of Sleep Apnea

Sleep apnea may be treated with lifestyle changes such as losing weight, cutting down on alcohol consumption and quitting smoking. Nasal training devices are also commonly used to treat sleep apnea. Other treatment for sleep apnea may include continuous positive airway pressure, or CPAP, which involves the patient wearing a pressurized mask over their nose while they sleep. The mask pumps air through the airway to keep it open.

If conservative treatment is unsuccessful in treating sleep apnea, there are other options available. Individuals who suffer from severe cases of sleep apnea that may lead to serious medical conditions, may benefit from surgery. The goal of most surgical procedures is to remove the excess tissue from the nose or throat and open upper air passages to facilitate breathing.

  • Uvulopalatopharyngoplasty
  • Maxillomandibular advancement
  • Tracheostomy
  • Thermal ablation palatoplasty
  • Genioglossus and hyoid advancement
  • Septoplasty and turbinate surgery

Custom made oral appliances may also be used to treat sleep apnea. Some devices are designed to open the throat by bringing the jaw forward, which can help to relieve snoring and mild obstructive sleep apnea.
