Autologous costal cartilage ball transplantation

Immediately after the eyeball is removed, the autologous rib cartilage ball is transplanted. After the long-term eyeball is removed, the eye socket depression can also be used as a self-body rib cage ball. Treatment of diseases: eyeball rupture, eyeball penetrating injury Indication Immediately after the eyeball is removed, the autologous rib cartilage ball is transplanted. After the long-term eyeball is removed, the eye socket depression can also be used as a self-body rib cage ball. Preoperative preparation 1, routine preoperative preparation. Conjunctival sac culture and antibiotic susceptibility test, broad-spectrum antibiotic ophthalmology was instilled into the conjunctival sac. The conjunctival sac was washed with saline before surgery. 2. The operation is performed under local anesthesia. Surgical procedure Preparation method of autogenous rib cartilage ball: The most abundant part of cartilage in human body is the costal cartilage of the sixth, seventh, eighth and ribs and their mutually connected parts. Surgery should be performed under epidural anesthesia. The rib cartilage is used as an incision, and the skin and subcutaneous tissue are cut open to the rib, and the incision is generally not less than 7 cm. Sneak separation on the upper and lower sides to fully expose the costal cartilage. The cartilage periosteum was cut in the direction of the ribs, and the periosteum of the costal cartilage was peeled up and down to reach the upper and lower edges of the ribs. The rib periosteum stripper is placed under the perichondrium of the upper and lower edges of the ribs under the perichondrium behind the costal cartilage. The costal cartilage periosteum behind the costal cartilage in the cut-out range is sufficiently peeled off. A piece of costal cartilage is cut according to the surgical requirements, usually about 7 cm long. The costal cartilage segment was removed and wrapped in saline gauze for later use. The perichondrium is sutured, and the muscles, subcutaneous tissue and skin are layered. The surface of the sterilized dressing is fixed with a wide tape according to the rib fracture treatment method to limit the lower chest to reduce postoperative discomfort. Remove the rib cartilage segment, cut into 3 pieces, one big and two small, large centered, small placed on both sides, the middle is fixed with a thin wire, so that it is spherical, slightly trimmed, cut off the corners for use. In general, the size is 17 to 20 mm, the vertical diameter is 15 to 18 mm, and the transverse diameter is 17 to 20 mm. The volume of the cartilage sphere is about 3 to 4.5 ml. Autologous costal cartilage ball transplantation: 1. Open the device. The conjunctiva was cut horizontally in the central part of the posterior wall of the conjunctival sac, and the incision was made from the medial malleolus to the iliac crest, and the subconjunctival tissue was separated to expose the fascia of 2. The patient rotates the healthy eye, and the position of each rectus muscle is recognized by the flap, and the oblique ocular fascia incision is made between the rectus muscles, and the pericardium is in each valve. Separate deep into the eye socket, loosen the adhesion, and fully expand the muscle cone cavity. Pressure to stop bleeding. 3. The assistant holds the conjunctival incision margin with tweezers and gently lifts it up. The surgeon implants the pre-prepared cartilage ball into the muscle cone cavity. 4. The eyeball fascia was sutured up and down and inside and outside, the conjunctiva was continuously sutured, and the tonic was placed in the conjunctival sac. Compression dressing.
