Sleeping with snoring sound, is the upper respiratory tract airflow through the impact of the soft palate mucous membrane edge caused by vibration and produced, may be related to the nasal septum deviation, nasal polyps, chronic rhinitis and so on. 1. Deviated nasal septum: The nasal septum is morphologically deviated or partially protruded to one side or both sides, thus causing symptoms such as nasal congestion, nosebleed and headache. Due to nasal congestion and open-mouth breathing, the airflow can be directed to the soft palate, and severe snoring occurs during sleep. 2. Nasal polyps: the extremely edematous nasal mucosa forms single or multiple polyps in the middle nasal tract as the clinical feature. Severe patients may have occlusive nasal sound in speech and open-mouth breathing during sleep, which may lead to sleep snoring or even apnea. 3. Chronic rhinitis: mainly characterized by swelling of nasal mucosa and increased secretion. Due to the nasal congestion, it can cause the patient’s soft palate vibration and snoring during sleep. It is recommended that patients go to the hospital in time to improve the relevant examination, to clarify the reasons for snoring and follow the doctor’s instructions to standardize the treatment.
