Non-surgical treatment modalities are mainly used for patients with OSAHS.
Surgical treatment, however, requires strict indications for surgery and is only suitable for patients for whom surgery can indeed relieve upper airway obstruction (including pharyngeal mucosal tissue hypertrophy, narrow pharyngeal cavity, uvula hypertrophy, low soft palate, tonsillar hypertrophy) and apnea hypoventilation index (AHI) <20 breaths/h; it is not suitable for obese people and those with AHI >20 breaths/h.
In some non-obese patients with severe OSAHS with significant oropharyngeal obstruction, surgical treatment can be considered when continuous positive airway pressure (CPAP) has been applied for 1 to 2 months and nocturnal apnea and hypoxia have been largely corrected.
