Possible causative factors of snoring include: deviated nasal septum, enlarged tonsils, and mandibular retraction deformity.
1. Deviated nasal septum: The deviation of nasal septum bone and cartilage can lead to the obstruction of nasal ventilation and open-mouth breathing. The airflow passes through the pharyngeal cavity and hits the soft palate to make snoring sound.
2. Tonsillar hypertrophy: Tonsillar hypertrophy causes narrowing of the pharyngeal cavity, the cross-sectional ventilation rate of the oropharyngeal airway increases, and the airflow triggers an increase in the vibration of the soft palate, causing snoring.
3. Mandibular retraction deformity: the mandible retracts backward, causing the root of the tongue to be close to the posterior wall of the pharynx, guiding the airflow to impact on the soft palate, resulting in the symptoms of snoring.
Snoring may also be caused by obesity, adenoid hypertrophy, nasal polyps and tongue hypertrophy, etc. You can actively seek medical treatment and systematic examination to clarify the diagnosis and specific causes.
