Mucous cysts are medically known as salivary gland mucous cysts, and their main causes are related to local trauma, obstruction of the ductal system, and predisposing factors.
1. Local trauma: For extravasated mucous cysts, usually caused by local trauma, it will be due to the rupture of the duct, the mucus leakage into the tissue space, thus forming extravasated mucous cysts.
2. Ductal system obstruction: For retention mucus cysts, they are mainly caused by ductal system obstruction. Patients may have retention mucus cysts caused by factors such as ductal system curvature, microscopic salivary gland stones, or concentrated secretions.
3. Predisposing factors: The predisposing factors of this disease are considered to be related to poor hygiene habits, tongue movement and oral structure.
It is recommended that the patient should go to the hospital and cooperate with the doctor to find out the specific cause of the disease, and then do the next step of examination and treatment.
