Snoring in adults with enlarged tonsils belongs to simple snoring or obstructive sleep apnea syndrome caused by obstructive factors in the pharynx, which can generally be treated by surgery or by choosing non-invasive positive airway pressure ventilation. The narrowing of the pharyngeal cavity caused by tonsillar hypertrophy and the snoring caused by the impact of ventilation inflow on the edge of the soft palate mucosa during breathing can be relieved by palatine tonsillectomy to remove the obstructive factors under the premise that there is no absolute contraindication to surgery. If the patient’s physical condition does not allow surgical treatment, or if the patient is not willing to take surgical treatment, continuous positive pressure ventilation and bi-level positive pressure airway ventilation can be chosen to keep the patient’s upper airway open through mechanical ventilation with certain pressure, so as to ensure smooth breathing during sleep. If adults with enlarged tonsils snore, it is recommended to actively go to regular hospitals for consultation and examination to clarify the extent of the condition and take targeted treatment measures in time.
