Snoring is the vibration of respiratory structures and the resulting sound due to obstructed air movement during breathing while sleeping. The sound may be soft or loud and unpleasant. Snoring during sleep may be a sign, or first alarm, of obstructive sleep apnea (OSA). Research suggests that snoring is one of the factors of sleep deprivation. Causes
Snoring is the result of the relaxation of the uvula and soft palate. These tissues can relax enough to partially block the airway, resulting in irregular airflow and vibrations. Snoring can be attributed to one or more of the following:

Genetic predisposition, a proportion of which may be mediated through other heritable lifestyle factors such as body mass index, smoking and alcohol consumption. Throat weakness, causing the throat to close during sleep. Mispositioned jaw, often caused by tension in the muscles. Obesity that has caused fat to gather in and around the throat. Obstruction in the nasal passageway. Obstructive sleep apnea. Sleep deprivation. Relaxants such as alcohol or other drugs relaxing throat muscles. Sleeping on ones back, which may result in the tongue dropping to the back of the mouth. Mouth breathing

Possible consequences
Snoring is known to cause sleep deprivation to snorers and those around them, as well as daytime drowsiness, irritability, lack of focus and decreased libido. It has also been suggested that it can cause significant psychological and social damage to those affected.
The most dangerous risk is that enough scar tissue could form within the throat as a result of the incisions to make the airway more narrow than it was prior to surgery, diminishing the airspace in the velopharynx. Scarring is an individual trait, so it is difficult for a surgeon to predict how much a person might be predisposed to scarring. Currently, the American Medical Association does not approve of the use of lasers to perform operations on the pharynx or uvula. Radiofrequency ablation (RFA) is a relatively new surgical treatment for snoring. This treatment applies radiofrequency energy and heat (between 77 °C and 85 °C) to the soft tissue at the back of the throat, such as the soft palate and uvula, causing scarring of the tissue beneath the skin. After healing, this results in stiffening of the treated area. The procedure takes less than one hour, is usually performed on an outpatient basis, and usually requires several treatment sessions. Radiofrequency ablation is frequently effective in reducing the severity of snoring, but often does not eliminate it.Bipolar radiofrequency ablation, a technique used for coblation tonsillectomy, is also used for the treatment of snoring. Pillar procedure
The pillar procedure is a minimally invasive treatment for snoring and obstructive sleep apnea. In the United States, this procedure was FDA indicated in 2004. During this procedure, three to six+ Dacron (the material used in permanent sutures) strips are inserted into the soft palate, using a modified syringe and local anesthetic.
