Ways to Obtain Perfect Masticatory Function: Two-jaw Surgery
:: the FACE dental clinic
Two-jaw surgery moves the jaw bones and teeth to their ideal position to obtain overall facial balance. Irregular teeth and jaws cause prognathic jaw, short chin, protruded chin, and facial asymmetry. Two-jaw surgery repositions upper and lower jaws, and makes right occlusion of jaw and teeth possible. Therefore it is well known for its dramatic effectiveness.

However, two-jaw surgery requires a high degree of skill. There are many nerve lines in jaws and facial bones, especially around the lower jaw. In the process of moving and fixing the bones, there may be possibility of neurological damage in ramus mandibulae. Even one minor error may cause great danger.

Furthermore, if only one jaw(either upper or lower) is operated, more orthodontic tooth movement before and after surgery is required. Two-jaw surgery is chosen to compensate this or it is also chosen when surgery on both the upper and lower jaw is unavoidable because of the structure of teeth and jaw. However, this surgery covers wide range so side effects may occur post surgery. Masticatory function to chew or articulation may not be satisfactory. Aesthetical improvements may not meet your expectation. In case of narrowed air passages because of the narrowed space in the lower jaw, you may have snoring or sleep apnea.

Hence, we should stick to the basics to dispel worries about such side effects and to pursue the essential function of surgery and aesthetical improvements.

First, checking your surgeon's major is necessary. Two-jaw surgery treats jaws and facial bones. Therefore, medical specialists in various fields can perform two-jaw surgery. However, the most specialized in two-jaw surgery is an oral and maxillofacial surgeon. An oral and maxillofacial surgeon is specialized in jawbone fracture, temporomandibular dysfunction, orbital hypertelorism, and cranio-maxillofacial surgeries. Hence, an oral and maxillofacial surgeon is the most qualified to pursue the essential function of two-jaw surgery such as maticatory function to chew or articulation.

Second, expertise in orthodontics is important. Two-jaw surgery undergoes the process of a long period of orthodontic treatment before surgery, jaw fixation and orthodontic treatment after surgery. So the result of orthodontic treatment has a great influence on functional and aesthetical improvements.

Finally, checking the residence of an anesthesiologist is crucial since two-jaw surgery requires anesthesia. An anesthesiologist is in charge of the whole surgery including patient's stability and safety. So the patient's state must be reported to oral and maxillofacial surgeon and orthodontist moment by moment. However in some clinics, surgery is performed with an anesthesiologist on a freelancer basis. In such cases it is harder to concentrate on surgery compared to an anesthesiologist who resides in the hospital.

Dr. Lee Joong-kyou from the Face Dental Clinic, an oral and maxillofacial surgeon, points out that "Two-jaw surgery should place priority to the functional improvements of jaw and teeth. Then you can get perfect masticatory function, articulation, and an improved facial appearance as well." He also advises that "It is desirable to have surgery after checking your oral and maxillofacial surgeon's experience and reputation since he is the one who treats aesthetical and functional aspects of your face and jaw."
