A Study of Two Types of Absorbable Surgical Sutures in the Suturing of Thyroid Surgery Incision

This study adopts a multicenter, prospective, randomized controlled design. The study population are subjects who undergo thyroid surgery. Before the surgery, subjects are randomized in 1:1:1 ratio to the investigational group 1 (using Spiral PDS Plus), investigational group 2 (using Spiral MONOCRYL Plus) and control group. See the table below for the specific suture levels, materials and techniques of each group. A blinded central imaging evaluation will be performed on the healing condition of surgical incision on Day 5‐7 post‐surgery. The subjects will be blinded to the type of suture used for wound closure.
