PATHOLOGY

Detailed explanation-1: -Healing by first intention or Primary intention healing happens when the wound edges are approximated e.g. by sutures, staples or glue. Healing by second intention or Secondary intention healing takes place when the wound edges cannot be approximated and the wound needs to heal from the bottom.

Detailed explanation-2: -Secondary intention healing (SIH) is often underutilized and has several advantages compared to primary surgical repair. Wound care is minimal, bleeding and infection are rare, and risks associated with primary closure (e.g. hematoma, suture granuloma, graft or flap failure) are non-existent.

Detailed explanation-3: -The cosmetic outcome is often acceptable to patients, particularly older men with pre-existing hair loss. Disadvantages of second intention healing of large wounds are prolonged healing time and the necessity of diligent wound care.

Detailed explanation-4: -Wounds healing by primary intention are wounds that have been closed using stiches, skin glue, staples, etc. Most surgical incisions are an example of wounds that are healed by primary intention healing. Secondary intention healing is when a wound is left open. No sutures or other materials are used to close the wound.
