Modified Uniportal Periareolar Incision Versus Conventional Uniportal Video-assisted Thoracic Surgery for Pulmonary Nodules: Protocol for a Prospective, Randomized, Controlled Study

"The experimental group (patients received periareolar incision):~An arc-shaped incision was made on the lateral side of the patient's affected areola. The subcutaneous tissue was then dissociated between the lateral mammary gland and the skin to the level of the fourth intercostal space in front of the midaxillary line. The fatty tissue behind the breast was separated horizontally to expose the serratus anterior muscle, and an intercostal incision was made. The skin was pulled back throughout the procedure to expose a better surgical field and avoid damage to the mammary gland.~The control group (patients underwent an axillary incision):~For patients in the control group, an incision was made into the fourth intercostal space in the midline of the axilla, where subcutaneous tissue was separated and entered the chest."
