Dental cysts are generally referred to as odontogenic cysts, and whether or not the procedure for their treatment is a minor surgery needs to be determined by the condition. If the cyst is small, it is a minor surgery. On the contrary, it is a larger surgery. 1. If the cyst is only a few millimeters or <1cm, most of the surgeries are relatively minor and can be performed through local anesthesia with an open angular incision or T-shaped incision. 2. If the cyst reaches 2cm, or even >2cm in patients. Since the cyst is large and may affect bones, nerves and other tissues, its surgery is a relatively large or medium-sized surgery. Preoperative assessment should be carried out accurately, CT examination, to find the relationship between the cyst boundary and the surrounding important blood vessels and nerves, and then carry out the corresponding surgical treatment. It is important to minimize the trauma to the patient and achieve better treatment results. It is recommended that patients in need of dental cyst surgery go to a regular hospital in a timely manner and follow the doctor’s instructions for treatment to avoid delays.
