Snoring & Sleep Apnea
In September 1995, the American Sleep Disorder Association (ASDA) endorsed oral appliance therapy. Currently making it the third acceptable treatment for snoring and sleep apnea. The two most common solutions include a continuous positive air pressure or the removal of either the excess palatal tissue or the uvula.
It has been estimated that 60% of men and 40% of women between the ages of 40 and 60 years of age snore. Snoring occurs when there is a partial obstruction of the airway which causes the palatal tissues to vibrate. Obstructive sleep apnea occurs when the airway is completely blocked for certain periods of time.
As many as 20 million people in North America may have sleep apnea. Snoring is a social problem, particularly for the spouse. Obstructive sleep apnea poses a significant health risk for the individuals. It can lead to irregular heartbeat, high blood pressure, heart attacks, and strokes.
What is Sleep Apnea
Sleep apnea is a type of breathing disorder which is a serious, potentially life-threatening condition characterized by brief interruptions of breathing during sleep. There are basically three types of apnea:
- The upper airway is open, but no oxygen is getting into the system. This occurs because the patient is not getting a chemical response from the brain to stimulate the lungs and the diaphragm to assist with breathing.
- This is a combination of central and obstructive sleep apnea.
Obstructive Sleep Apnea
- The lungs and the diaphragm are functioning normally, but no oxygen is entering the system because there is an obstruction in the upper airway.
Oral appliances are only indicated for use in patients suffering from obstructive sleep apnea (OSA). The signs and symptoms of OSA include snoring, excessive daytime sleepiness, gasping or choking during the night, non-refreshed sleep, fragmented sleep, clouded memory, irritability, personality changes, decreased sex drive, impotence, and morning headaches.
Factors that affect obstructive sleep apnea are as follows:
- Sedative Hypnotics (sleeping pills)
Children can also snore and suffer from obstructive sleep apnea. Often they are highly allergic and their airway is blocked due to enlarged adenoids, tonsils or swollen nasal mucosa.
Clinical signs would indicate a turned up nose, allergic shiners under the eyes, mucous draining out of the nose, mouth breathing, and a nasal sound to the voice. Other signs are bed wetting, irritability, difficulty in concentrating at school and hyperactivity
