- Bone grafting; stellmach-schuchardt method; bone grafting is a one-time repair of cleft lip and anterior palate fissure, ICD code is 27.6904.
- In order to promote the bony healing of the precondylar fissure and prevent the maxillary dental arch from narrowing, Stellmach (1959) and Schuchardt (1962) successively proposed bone graft surgery. However, this type of surgery is very traumatic, which may cause maxillary dysplasia, and may also result in abnormal relationships due to bone graft fixation. Therefore, some people oppose this kind of surgery, and some people have proposed the use of periosteum transplantation. It is still controversial. Anterior fissure and surgical correction.
- Bone transplant surgery is suitable for:
- 1. Cleft lip with pre-condylar fissure and maxillary canine permanent teeth have sprouted.
- 2. The relationship is basically normal, with no obvious anti-superiority.
- 1. Those who are too young and who have not changed their maxillary canine teeth.
- 2. Those who have serious mistakes, such as anterior teeth reverse, maxillary dysplasia, or maxillary hyperplasia.
- 1. Routine oral cleansing.
- 2. Bone graft materials can be prepared using autologous sacrum, mandibular precondylar external bone plate, allogeneic bone or allogeneic, heterogeneous ceramicized bone composite bone morphogenetic protein (Bone Morphogenetic Protein, BMP), etc.
- This operation is performed before the cleft lip tissue flap is sutured.
- 1.Stellmach method
- (1) In the same way as the vulva flap method, first cut both sides of the fissure, flip the mucoperiosteal flap, and close the nasal side of the fissure relative to the suture (see "vulva mucosal flap method" for details).
- (2) At the rear end of the vomeral flap, cut out a pedicle of the periosteal flap, place the small bone graft in the fissure, and then flip the pedicled periosteal flap. Both sides of the pedicle are sutured with the alveolar wound edge The suture of the anterior and lip mucosa.
- 2.Schuchardt method
- First make the anterior alveolar fissure alveolar periosteal flap, turn the two flaps on the midline suture, close the nasal side of the fissure, and then place the bone graft in the fissure of the fissure. A rectangular mucosal flap is designed in the vestibular sulcus on the affected side to cover the surface of the bone graft, and the wound margin is relatively tightly sutured.
- 1. All mucoperiosteal flaps should be sufficient to completely cover the fissures and bone graft wounds, and need to be sutured closely. The tension should not be excessive after suture.
- 2. The pedicle of vulva mucosa periosteal flap should not be too narrow.
- After bone transplantation, do the following:
- 1. Iodine-like gauze strips should be sewn in the operation area to protect the wound.
- 2. Fasting should be performed 1 to 2 days after surgery.
- 3. Routine oral care after surgery.
- 4. The suture was removed 7 days after the operation.
- Infection
- 2. The main reason for the prolapse of the bone graft is the incomplete closure of the wound, infection or necrosis of the mucosal flap.
- 3. The upper lip roll occurs mainly in the Schuchardt method, and the medial mucosal flap of the upper lip is too wide.
