Modified sternocleidomastoid bipolar release and muscle Z-plasty

Modified sternocleidomastoid bipolar release and muscle Z-plasty for the correction of muscular torticollis. Congenital torticollis can be divided into congenital bony torticollis and muscular torticollis. The former is less common and the latter is more common. The cause of congenital muscular torticollis is still unclear, but it is most common when the neck is over-tracted during dystocia. More common on the right side. The hard mass of the middle and lower part of the sternocleidomastoid muscle is often reached within 2 weeks of the patient's birth, reaches the maximum extent within 2 months, and then decreases or disappears within 1 year. If it does not disappear, the muscle will permanently fibrillate and contract, causing a torticollis. Treating diseases: torticollis Indication Suitable for older children or those who have failed in the past. Contraindications Congenital bony torticollis. Preoperative preparation Prepare routinely before surgery. Surgical procedure 1. Cut off the apex of the sternocleidomastoid. Also take care to avoid damage to the accessory nerve. 2. Z-plasty of the lower end of the sternocleidomastoid muscle: a skin incision of 4.0-5.0 cm in length at the medial end of the clavicle of the sternocleidomastoid muscle and the neckline of the sternal notch, and the skin subcutaneous tissue is cut and The platysma shows the clavicular and sternal ends of the sternocleidomastoid muscle. The transverse clavicle is attached to the tendon, and the sternum segment is subjected to Z angioplasty to maintain the V shape of the sternocleidomastoid muscle. Thoroughly loosen other contracted muscles and soft tissues.
