Surgery-First Orthognatic Approach

ID Hospital is the first hospital to widely introduce the ‘Surgery First Orthognatic Approach’ to correct mandibular prognathism. As the name implies, surgery is carried out first and then orthodontic treatment is followed. ID Hospital has made this technique well-known in the field of cosmetic surgery.
 
 
  Treatment period is shortened.
Previous orthognathic treatments usually have a three-step treatment process which is pre-surgical orthodontic treatment → jaw (orthognathic) surgery → post-surgical orthodontic treatment. But in the surgery-first approach skips the pre-surgical orthodontic treatment which leads to a significant reduction in overall treatment time.
  Prevents aggravation of prognathism.
In previous orthognathic treatments, mandibular prognathism gets worsen during the pre-surgical orthodontic treatment period. This leads to a functional deficit in mastication and speech and also leads to a psychological distress state. All of these problems can be prevented by the surgery-first approach.
  Have surgery whenever you want.
The surgery-first orthognathic approach can make immediate changes in one's appearance after the surgery, and also the patient can have surgery whenever they want regardless of the orthodontic treatments.
 
 

ID two-jaw surgery

ID two-jaw surgery separates the upper and lower jaws and adjusts them in the correct position. The procedure is suitable for conditions including mandibular prognathism, mouth protrusion, facial asymmetry, and other abnormal positioning of the jaw. ID Hospital is proud to have recorded over 3,000 cases of two-jaw surgery. Depending on the degree of mandibular prognathism and malocclusion, either two-jaw surgery or lower jaw surgery will be chosen.
 
Two-jaw surgery
Two-jaw surgery means cutting(osteotomy) both the upper and lower jaw and repositioning it in a more functional and esthetic position. In a two-jaw surgery, lower jaw surgery is combined with Le Fort I osteotomy for the upper jaw. Two-jaw surgeries are needed when facial asymmetry is combined, when the degree of the mandibular prognathism is severe, when chin end is protruded, when orthodontic treatment has been done after teeth extraction, and when the facial length is long.
 
 
Lower jaw surgery
Lower jaw surgery is a procedure that cuts, setback and fix the lower jaw in a new position to treat mandibular prognathism. There are two common surgical methods in treating mandibular prognathism. Those are 'sagittal split ramus osteotomy(SSRO) and 'intraoral vertical ramus osteotomy(IVRO). We recommend SSRO rather than IVRO, since the former has shortened healing periods with wider contact areas between the cut bones which leads superior bone healing, and is also better on the aspect of esthetics.
 
 
Two-jaw surgery is required in
 
  • mandibular prognathism exceeds 10mm
  • the degree of mandibular prognathism and malocclusion differ greatly
  • teeth extraction and orthodontic treatment are completed
  • open bite
  • long face

No-tie two-jaw surgery

'No-tie' two-jaw surgery is named for two-jaw surgery that does not require intermaxillary fixation(IMF) after the operation. Conventional two-jaw surgeries need intermaxillary fixation and ties the upper and lower teeth for 2~6 weeks after the operation in order to let the bones heal and achieve an union state. On the other hands, 'no-tie' two-jaw surgery is a new surgical method introduced by ID hospital which does not need any post-surgical intermaxillary fixation. Instead, a 'torque-free rigid internal fixation' technique is used to let the mandible be positioned in the exact location and achieve complete bone union.
 
 
  More comfort
  • Easy breathing: Intermaxillary fixation causes swelling inside of the nose and difficulty in breathing due to blocking the mouth. The absence of intermaxillary fixation eliminates this pain and allows the patient to breathe comfortably.
  • Enjoy your meals: The patient must eat soft food for a certain period after surgery. In the past, the patient had difficulty chewing food with their teeth tied but the new surgical procedure allows the patient to enjoy their meals without any discomfort in chewing with the mouth open.
  • Easy speaking: Intermaxillary fixation caused difficulty in speaking, but the new procedure allows the patient to speak freely without any pain or discomfort.
  Safe & clean
  • Safe breathing: Intermaxillary fixation causes nasal congestion and other breathing discomfort, which requires families and medical staff to provide intense post-surgical care. This may cause the patient to feel uncomfortable. No-tie two-jaw surgery minimizes this psychological anxiety and eliminates risks of side-effects.
  • Clean oral hygiene: Chewing food with tied teeth caused difficulty in maintaining dental hygiene for the patients. The absence of intermaxillary fixation enables patients to maintain dental hygiene in an easy way.
  Fast recovery to normal daily life.
  • The temporomandibular(TM) joint recovers fast: Intermaxillary fixation usually stiffens the TM joint which requires the patient to practice opening and closing the jaw. But the no-tie two-jaw surgery does not require intermaxillary fixation and does not cause stiffness of the TM joints.
  • Return to daily work faster: Speaking is easy because intermaxillary fixation is not needed, allowing patients to return to work faster.
 
 

Facial Contouring Surgery

If asymmetry is only on the facial contour, facial contouring surgery or simple genioplasty can seek great results instead of a two-jaw surgery.
 
V-line Surgery
The lower portion of the chin bone is excised in a T-shape and the cut piece that sticks out at the tip is removed. ID Hospital was the world’s first hospital to introduce this procedure, calling it ‘T-osteotomy’. In case the patient has facial asymmetry, V-line is formed by varying the amount of jaw bone excised at each side.
 
 
 
Volumetric mandible reduction surgery
When the patient has a wide lower jaw and facial asymmetry, Volumetric mandible reduction surgery is carried out by varying the amount of bone excision on each side of the jaw.
 
 
 
Facial Contouring Surgery
 
 
 
Genioplasty
The tip of the chin is excised and removed, thereby shortening the length of the jaw line. This procedure minimizes the damage done to the nerves but it is still a very sensitive procedure.
