Snoring is mostly seen in adult obese men. Snoring can also cause fatal complications in severe cases. Snoring is caused by airflow through the upper airway during sleep causing vibration of the edges of the pharyngeal mucosa and secretions on the mucosal surface. Obese people with excess fat accumulation and narrowed pharyngeal cavity are more prone to snoring. Other symptoms of snorers include daytime sleepiness, early morning headache, mood and behavior disorders such as restlessness, personality changes, excessive dreaming and urination. Based on these characteristics of snoring, it is not difficult to make a diagnosis, but the key is to correctly distinguish which type of snoring belongs to, because the treatment principles and means for central, obstructive and mixed snoring are different. Sleep apnea monitoring can make a clear diagnosis. Patients only need to rest in the sleep apnea monitoring laboratory for one night to know the quality of their sleep, whether they have snoring, the degree of impact on the systemic systems, which type they belong to and what kind of treatment they are suitable for. Overview Snoring (medical term for snoring, snoring, sleep apnea syndrome) is a widespread sleep phenomenon, which most people currently consider as commonplace and do not take it seriously, while others see snoring as a sign of a good night’s sleep. In fact, snoring is the enemy of health, due to snoring makes sleep breathing repeatedly suspended, resulting in serious lack of oxygen to the brain, blood, the formation of hypoxemia, and induced hypertension, cerebral heart disease, heart rate disorders, myocardial infarction, angina pectoris. Nocturnal apnea for more than 120 seconds is prone to sudden death in the early morning. Symptoms 1. Severe snoring sound, but snoring is terminated from time to time. The patient’s sleep causes narrowing of the upper airway due to airway relaxation, collapse and backward tongue root, etc. The airflow passes through the narrow pharynx during breathing, causing the soft tissues of the pharyngeal cavity to flutter and emit snoring sound. 2. Daytime dozing. Patients often feel sleepy and dizzy during the day, and whenever they are in a meeting, listening to a lecture, reading, watching TV, riding in a car or even driving, they yawn one after another and fall asleep quietly, and snore like thunder. When waking up and sleeping again, but the quality of sleep is poor, patients often sleep for a long time and are still confused and sleepy. 3. Breath-holding and apnea occur frequently during sleep. When snoring patients sleep at night, breath-holding is often triggered by breathing blockage, and each breath-holding time is as little as ten seconds or as long as several minutes, and severe patients are awakened by breath-holding many times a night. Patients often stop snoring suddenly after they have been sleeping loudly for a period of time, and their breathing is suspended, and the patient’s mouth and lips become blue and purple, showing painful struggle, accompanied by sweating profusely. Sometimes the patient suddenly turns over or sits up, and then sends out a coarse grunting sound from the throat, which is harsh and hard to hear, with a variety of sounds. Especially in the dead of night, the continuous grunting sound is unusually loud and annoying. The patient’s family enjoys the “ear blessing” and can’t sleep peacefully and have dreams. Other manifestations of snoring include: increased urination and urine loss at night; headache, dizziness and weakness in the morning; slow reaction, poor memory and inability to concentrate in the daytime; change in personality of some patients, temperamental, irritable and depressed; and declining libido in some patients. Etiology 1, congenital anatomical malformation: mandibular developmental malformation, mandibular recession, etc. 2, pharyngeal causes: tonsils and adenoids enlarged hypertrophy, uvula hypertrophy, soft palate hypertrophy hypoplasia, tongue hypertrophy. 3.Nasal causes: nasal septum deviation, nasal polyps, turbinate hypertrophy, nasal mucosa congestion and hypertrophy, chronic rhinitis, etc. 4. Functional causes: normal airway during daytime wakefulness, reduced muscle tension around the airway during sleep, combined with the backward fall of the tongue root when lying down, resulting in airway narrowing and snoring.
