Around mid-autumn last year, a sudden cry for help came from a sauna – it turned out that a “big fat guy” who was enjoying a massage and snoring was having difficulty breathing, his whole body was cyanotic and his consciousness was impaired, but fortunately there were medical professionals present to administer artificial respiration, and he gradually woke up. Afterwards, the “big fatty” went to the Department of Otolaryngology of the First Hospital of Zhongshan Medical University and was found to be suffering from “obstructive sleep apnea syndrome”, also known as “breath-holding snoring It is also called “breath-hold snoring”. As early as the 19th century, people already noticed this disease characterized by obesity, drowsiness, snoring and holding awake, and Dickens used this feature to describe his main character Joe in his famous book Pickwick’s Tale, but it was not until the end of the last century that this disease attracted widespread attention from all walks of life. For a long time, people have thought that sleep snoring is a sign of sound sleep, but it is not. There are occasional occurrences of sleep snoring and frequent episodes. Among the frequent sleep snorers, there are simple snoring and obstructive sleep apnea syndrome. Sleep snoring is a sound caused by the vibration of mucous membrane edge and mucous membrane surface secretion when airflow passes through the narrow part of upper airway at high speed during breathing, which is more obvious during inhalation and can also occur during exhalation. Some people who usually do not snore can snore when they are tired, drink alcohol or sleep in supine position; eating greasy food increases the secretion of respiratory mucous membrane, which can make the snoring sound significantly aggravated. If the loudness of snoring exceeds 60dB, which affects the rest of people in the same room or causes others to be annoyed, but the snoring is even and regular, with consistent sound height and not accompanied by apnea as simple snoring. Some people snore continuously during sleep, the sound is high and low, often intermittently for tens of seconds without sound, sometimes with a terrible shout, or even apnea or asphyxiation, or even wake up, and at the same time, due to lack of oxygen, poor sleep quality, morning sleepiness, drowsiness, poor memory, head swelling and headache, which is mostly seen in patients with obstructive sleep apnea syndrome, which can lead to pulmonary heart disease over time, leading to heart failure and death by exhaustion. . Any factors that can lead to narrowing of the nasopharyngeal airway can trigger snoring, such as congenital dysplasia of the airway, deviated nasal septum, nasal polyps, hypertrophy and congestion of the nasal mucosa, tonsils and adenoid hyperplasia, deformed development of the mandible or receding backward, hypertrophy of the suspensory pendulum, low hanging soft palate, fat tongue, etc. In obese people, the accumulation of fat in the neck can also narrow the airway and cause snoring. In the supine position, the tongue root drops back, which can also cause airway narrowing and affect the normal passage of airflow. Occasional sleep snoring does not require special treatment and can generally be improved by changing the sleep position. The treatment of “snoring or obstructive sleep dyspnea syndrome” can be divided into two categories, namely conservative treatment and surgical treatment, and a single treatment mode does not necessarily achieve good results for all cases, while comprehensive treatment is expected to achieve satisfactory results for most cases. Conservative treatment includes medication, weight loss and the application of some medical devices. Pharmacological treatment involves avoiding drugs that reduce central nervous system excitability such as sleeping pills, narcotics and alcohol; applying nasal mucosal constrictors and steroid sprays to improve airway structure and compliance. If the patient has good airway compliance, the application of medical devices such as intranasal positive pressure ventilation therapy and tongue rest can effectively improve the symptoms. As snoring is associated with obesity, an active and effective weight loss program and its implementation can help improve the symptoms. The effectiveness of surgical treatment is related to the cause of the disease, the site of obstruction and the choice of different types of surgery. However, in many clinical cases, the obstruction is often in more than one part, for example, the posterior fall of tongue root is one of the most common reasons affecting the effect of palatal surgery, and it is often necessary to supplement with mandibular advancement to obtain satisfactory results. If pediatric snoring is caused by adenoid and tonsil hypertrophy, adenotonsillectomy should be performed, and the hypertrophied adenoids and tonsils must be removed at the same time. For cases of giant tongue with obstructive sleep apnea, tongue reduction is available. After the aforementioned “big fatty” underwent uvulopalatopharyngoplasty, his snoring during sleep basically disappeared, and he no longer woke up, and he was in good spirits every day.
