What is the primary purpose of suturing in flap closure?

The primary purpose of suturing in flap closure is to ensure that the tissues are properly approximated without causing tension. When sutures are placed without tension, it promotes better healing and minimizes the risk of complications such as tissue ischemia or necrosis. Properly placed sutures facilitate the natural healing process by allowing for adequate blood flow to the tissues while providing stability to the flap.

Tension on the tissue can lead to increased swelling, pain, and a higher chance of wound dehiscence, which can compromise the surgical site. Therefore, it is essential to ensure that sutures are positioned in a way that does not pull on the surrounding tissues excessively, thus allowing optimal healing conditions.

Other options may suggest methods that do not align with the best practices of suturing for flap closure. For example, placing sutures tightly could indeed cause ridging and poor blood circulation to the tissues, while inserting them only above the incision line or at incorrect angles may lead to inadequate flap adaptation or increased tissue trauma.
