Invisible lines on the skin where tension is minimal; incisions should follow these lines for better healing.

Incisions made parallel to tension lines heal faster and with better aesthetics than those made across them.

Puckered tissue at the ends of sutures when wound tension is high; minimize dog ears by following tension lines.

A technique to separate skin from underlying tissues to relieve tension during wound closure.

The process of adjusting wound edges to determine the direction of least tension before closure.

Inflatable devices used for tissue expansion before reconstruction surgery.

Injecting air or fluid into an expander over days to stretch tissue.

Sutures placed in the subdermal fascia to reduce skin tension and scarring.

Sutures that distribute tension and help close a defect by moving skin towards the center.

Sutures that prevent cutting out by spreading pressure over a larger skin area.

A standard tension-relieving suture that helps maintain closure without cutting skin.

Preferred method for large wound reconstruction over tissue expanders.

Sutures that help minimize tension on wound edges during healing.

Vertical mattress sutures usually removed by the third day after surgery.

Use unequal suture spacing; closer on convex side, wider on concave side.

Method to outline and remove redundant skin to help avoid dog ears.

A technique using 'far-near-near-far' or 'far-far-near-near' to alleviate tension.

Using padded material beneath suture loops to relieve tension.

Thin elastic skin is less likely to form dog ears compared to thick skin.

A surgical technique to reshape skin by creating a Z-shaped incision to reduce tension and aid closure.

Z-Plasty reduces the tension on wounds by reorienting the skin closure line.

The limbs of a Z-Plasty are cut at a 60° angle towards the Z's center.

Z-Plasty is usually performed ≥ 3 cm from the primary incision for effectiveness.

The tips of the Z in Z-Plasty can be rounded to prevent tissue necrosis.

Evaluate skin tension and elasticity before tumor removal to ensure proper healing post-surgery.

In tumor removal, excise the tumor and normal tissue margins based on tumor type; benign need 1 cm, malignant need 2-3 cm.

Undermining helps assess and adjust the closure techniques for skin during tumor excision.

Achieving excision inclusive of tumor, biopsy sites, and wide normal tissue margins in all dimensions.

Surgery to close defects caused by trauma, congenital issues, or tumors.

Incisions made to relieve tension on surrounding tissues during wound closure.

Tissues partly detached from a donor site and moved to cover a defect.

Transfer of a skin segment from one site to another, usually distant.

The area receiving a graft or flap, affecting healing and technique choice.

Surgical method that minimizes tissue damage and preserves blood supply.

Factors that can hinder skin blood flow include tension and rough techniques.

Method to stretch skin to reduce closure tension during surgery.

Devices used to gradually stretch the skin by inflating them.

Avoid handling traumatized skin until its circulation improves.

Healing is faster and better when incisions follow tension lines.

Close wounds to reduce tension and avoid puckering.

Separating skin from tissues to relieve tension before closure.

Align wound closure with the long axis when tension is low.

Incisions at angles to tension lines tend to gape and need more sutures.

Attachment of leeches to skin for medicinal purposes, mainly in impaired venous circulation.

Hirudo medicinalis; used for bleeding wounds due to their anticoagulant properties.

Excessive tension can lead to discomfort, necrosis, and dehiscence in sutures during healing.

Methods include undermining wound edges, selecting suture patterns, and using relief incisions.
