Oral cysts are generally defined as oral and maxillofacial cysts that become smaller on their own not healed. Oral and maxillofacial cyst is a non-abscessory pathologic cystic cavity that occurs in the oral cavity and the maxillofacial region, and is more common in oral and maxillofacial surgery. It is mainly caused by developmental abnormalities, infection, injury and other reasons. Most patients with this disease have no conscious symptoms, mainly spherical, deep, well-demarcated cystic masses in the oral and maxillofacial region. Because the patient has already appeared lesions, and this disease is not self-limiting, so the cyst becomes smaller is not a sign of healing, but after active treatment can be cured. It is recommended that patients with oral and maxillofacial cysts go to the hospital in time and follow the doctor’s instructions for treatment to avoid delay.
