Surgical treatment for alveolar synostosis is usually performed during the patient’s pubertal developmental period, at the time of first menstruation for girls and basically at the age of 11-12 years for boys. During that period, the patient’s growth and development is accelerated, and alveolar synostosis surgery at this time facilitates jaw development later in life. Alveolar fissure is an interruption of the bone, in the oral cavity, nasal cavity for the connection, the treatment is first of all to interrupt the connection between the mouth and nose, and further artificially cause the mouth and nose to be partitioned, to clearly ensure that the liquid in the oral cavity will not be through the alveolar fissure to enter into the nasal cavity. Therefore, the first step of the surgery is the soft tissue separation, and the second step is the bony interruption, which requires an autogenous bone graft to restore the bony connection, which is necessary for the future development of the maxillary bone or for the future orthodontic restoration of the dental alignment. So alveolar cleft surgery has a bony graft in addition to soft tissue closure.
