What is a rib graft?
Rib grafting is a type of free graft that is used in order to reconstruct structurally compromised regions of the head, face, and neck. It involves removing a portion of the actual rib from the chest wall and using that cartilage in reconstructive procedures.
What is a cartilage graft?
Cartilage grafting is a surgical procedure that replaces damaged cartilage with healthy cartilage from a non‐weight bearing joint. Cartilage grafting is performed to correct joint deformities and restore the weight‐bearing capability of the affected joint.
What is cadaver rib cartilage?
When cadaver cartilage is used, the cartilage is harvested from the cadaver and then radiated to make sure there is no chance of any kind of transmittable disease. The cartilage is then shaped as it would be if the patient’s own cartilage was used and placed into the appropriate position.
How do you do a rib graft?
Rib cartilage harvesting is preferentially performed on the patient’s left side to facilitate a two-team approach. Marking is initiated by palpating the sternomanubrial joint, which indicates the position of the second rib. The ribs are then palpated and numbered according to their position.
What is a cartilage graft in rhinoplasty?
A cartilage graft means that your plastic surgeon will collect cartilage tissue from another part of your body, and incorporate that tissue when constructing and reshaping your nose. As mentioned above, cartilage can be found in many sites of your body.
Where do cartilage grafts come from?
Commonly, grafts are sourced from other cartilage in the nose (septal cartilage), conchal cartilage (ears), or the rib cartilage. If performed by a skilled and experienced plastic surgeon, like board-certified plastic surgeon and nose specialist Dr.
Where is costal cartilage?
The costal cartilages form part of the thoracic cage and anterior chest wall. There are ten costal cartilages bilaterally, one for each of the corresponding 1st to 10th ribs, and each of the first seven ribs forms one of the seven costochondral joints.
What is cartilage resorption?
Primary cartilage resorption is preceded by diffusion of substances which produce a change in the cartilage matrix and necrosis of adjacent chondrocytes. In some areas chondrocytes transform into, or are replaced by, bone-producing cells and osteoid is observed within the chondrocyte lacunae.
Can rib cartilage be used as an implantable graft for rhinoplasty?
Auricular cartilage, irradiated cartilage, and alloplastic materials have all been used as implantable grafts with limited success. Results:In the senior author’s experience (J.P.G.), rib cartilage has proven to be a reliable, abundant, and relatively accessible donor with which to facilitate successful secondary rhinoplasty surgery.
What determines the amount of cartilage required for a rib replacement?
The amount of cartilage required dictates whether the cartilaginous segment from one rib, one rib and a portion of another, or the entire cartilage segments of two ribs need to be har- vested. In general, one should choose the carti- laginous portion of a rib that provides a straight segment with sufficient cartilage to fabricate all grafts.
How do you choose the right rib for a rhinoplasty?
In general, one should choose the carti- laginous portion of a rib that provides a straight segment with sufficient cartilage to fabricate all grafts. It is often possible to construct all required grafts from the cartilaginous portion of a single rib.
How do you do a rib graft for a dog?
Cover wound and obtain rib graft using separate instruments. Complete donor site incision through skin, subcutaneous tissue, and rectus abdominis muscle to expose costal cartilage while carefully preserving outer perichondrium. Outline rectangular segment 1 cm longer than measured stenosis and mark.
