Snoring as a disease is clinically called sleep breathing disorder, more commonly known as sleep apnea syndrome. It can be divided into three conditions, first, central sleep apnea syndrome; second, obstructive; and third, which is a combination of both conditions – mixed sleep apnea syndrome. The first one is caused by central respiratory lesions and is not within the scope of ENT treatment, so here we talk about the general diagnosis and surgical treatment of the second condition, obstructive sleep apnea syndrome. It is only in the past 10 years that snoring has become a disease that people pay attention to, because when snoring occurs, it is often accompanied by low blood oxygen and sleep disorders during sleep, and long-term chronic low blood oxygen can lead to a variety of chronic diseases, such as hypertension, cerebral infarction and other cardiovascular diseases, such as diabetes, obesity and other metabolic diseases, sexual dysfunction in adult men, developmental disorders in children, plus pharyngitis caused by open-mouth breathing when snoring, oral odor, and severe snoring. , oral odor, separation of couples caused by the noise of severe snoring (which is not uncommon among middle-aged and elderly couples). All these problems make us take snoring seriously, which is an easy topic to talk about. As the name suggests, obstructive sleep apnea syndrome (OSAHS), is a disease that arises when the upper airway (including the nasal cavity, oropharynx, laryngopharynx, and larynx) becomes obstructed. The diagnosis is made by sleep monitoring tests, which can distinguish between central or obstructive, and can determine the degree of hypoxia, among other things, and is currently an important test for this disease. When sleep monitoring confirms the presence of OSAHS and the patient is able and willing to undergo surgical treatment, surgical (operative) treatment in ENT can be performed. As mentioned before, the upper airway obstruction points include the nasal cavity, pharynx, etc. Therefore, there is no single obstruction point, and there are various diseases involved: rhinitis, sinusitis, nasal polyps, deviated nasal septum, adenoid hypertrophy, tonsillar hypertrophy, palatal pendulum (uvula) hypertrophy, soft palate hypertrophy, tongue root hypertrophy (lingual tonsillar hypertrophy), small jaw deformity, etc. Therefore, the possible surgeries involved can be said to be There are various surgical methods, including traditional surgery, laser plasma surgery, submucosal implant surgery, etc. Non-surgical treatments include positive pressure ventilation (C-PAP), commonly known as wearing a ventilator, and oral orthoses, which are suitable for patients who are too weak to tolerate surgery or unwilling to undergo surgery, and have certain efficacy.
