Snoring is a common sleep phenomenon, many people think that it is commonplace, and do not think, and there are people who see snoring as the performance of a good night’s sleep. In fact, snoring is the enemy of health, due to snoring so that sleep breathing repeated pauses, resulting in a serious lack of oxygen to the brain, blood, the formation of hypoxemia, and induced hypertension, cerebral cardiopathy, arrhythmia, myocardial infarction, angina pectoris. Nighttime apnea of more than 120 seconds is prone to sudden death in the early morning. The airway of a snorer is usually narrower than normal, and the compensatory contraction of the throat muscles during daytime wakefulness keeps the airway open and not blocked. However, at night during sleep the nerve excitability decreases, the muscles relax, the pharyngeal tissues are blocked, so that the upper airway collapses. When the airflow passes through the narrow part, it generates vortex and causes vibration, thus snoring occurs, and in severe cases breathing can be temporarily halted, which affects the person’s physical health. There is also a small percentage of people who suffer from central causes. Various causes of respiratory stenosis, mainly the narrowing of the upper airway above the plane of the trachea can cause snoring or even apnea, specifically including: nasal septum deviation, nasal polyps and other causes of nasal stenosis. Pharyngeal stenosis: enlarged tonsils, flaccid pharynx, prolonged uvula. Pharyngeal stenosis caused by hypertrophy of the tongue, tumor of the root of the tongue, and tongue suffix. Maxillofacial developmental deformities, such as small jaw deformity, etc., obesity. Children mostly due to tonsil hypertrophy and adenoid hypertrophy. What about snorers? First of all, you only need to do overnight polysomnography monitoring, you can understand your own sleep quality, sleep, how many times the apnea, how much time each pause, sleep oxygen in the blood, sleep heart rate changes, etc., polysomnography is now considered snoring patients must be an important examination, it can be the patient’s night sleep electroencephalogram, electroencephalogram, electromyography, oronasal airflow and oxygen saturation and heart rate, etc. to the dynamic examination of the patient’s night sleep, the electroencephalogram, electromyography and oxygen saturation. It can observe the patient’s EEG, ECG, EMG, oral and nasal airflow and oxygen saturation during night sleep, and heart rate dynamically, so as to understand the extent of the impact of snoring on the body, and then guide the treatment of snoring. Your doctor will evaluate and select the treatment based on your polysomnogram. Depending on the plane of obstruction, different surgical methods will be chosen. For example, patients with nasal obstruction should undergo nasal surgery to clear the nasal passages. Patients with pharyngeal stenosis can undergo palatopharyngoplasty, a surgical procedure that focuses on treating snoring by removing a portion of the uvula and tonsils and enlarging the pharyngeal space, it is the most common surgical procedure used to treat snoring and sleep apnea. Its success is determined by the choice of patients for surgery. In addition, patients with small jaws are prone to tongue retraction, so they can have surgery such as orthognathic surgery. Continuous Positive Pressure Ventilator (CPV) and Oral Orthosis can also be used to treat snoring. The main principle of Continuous Positive Airway Pressure (CPAP) is to widen the narrow part of the pharynx by wearing a small CPAP machine during sleep and connecting the mask to the ventilator, similar to the principle of blowing up a balloon. The pressure needed is different for each patient, so it is necessary for the doctor to use polysomnography to determine an appropriate pressure.CPAP machine can significantly increase the level of oxygen in the blood, and it is suitable for patients with moderate to severe snoring and those who have failed other treatments. Further, patients who snore are mostly obese. It is important to lose weight for a long time to maintain a normal body weight, and they should eat more light food, such as vegetables and fruits, smoke less, drink less, go to bed early, get up early, and do more physical exercise.
