Subjects and methods: 23 male and 59 female cases. Age ranged from 15 to 65 years, with an average of 36 years. There were 53 cases of nodular goiter, 11 cases of thyroid cyst, 8 cases of thyroid adenoma, 5 cases of primary hyperthyroidism, 2 cases of Hashimoto’s goiter, and 3 cases of microscopic thyroid cancer. There were 43 cases of unilateral nodules, 34 cases of bilateral nodules, and 7 cases without obvious nodules. The nodules were 0.5-7.5 cm in diameter, with an average of 3.4 cm. All cases were treated with a transverse cervical incision of two fingers above the sternocervical vein incision, with an average length of 4.0-6.0 cm and 5.0 cm. Layer-by-layer suturing: 1. Broad cervical muscle: interrupted sutures with No. 1 silk thread, about 0.2 cm from the edge and 1.0 cm between stitches, cut close to the knot. 2. 2. Subcutaneous fat: interrupted knot-embedding suture. If there is more fat tissue, the larger fat particles can be removed first. The suture is first entered from below the subcutaneous fat on the opposite side, and exited from above, 0.2-0.3 cm, with a little dermis, and then entered from above the same side with a little dermis, and exited from below, tying the knot below the subcutaneous fat with a distance of about 1.0 cm. The suture is best staggered with the suture of the cervical muscle layer. 3. Skin: Intradermal suturing is used. Prolene non-absorbable sutures of 3~0 are applied with assistant pressure.
