What is the primary clinical consideration when choosing secondary over primary healing?

• A. Time of day
• B. Season of the year
• C. Patient age
• D. Wound size and tissue loss

Answer: (D)

Deciding between secondary and primary healing hinges on the wound’s tissue characteristics. If the wound is small, clean, and the edges can be pulled together without tension, closing it right away (primary healing) is feasible. When there is substantial tissue loss or the edges cannot be approximated, closing the wound risks trapping nonviable tissue and infection, so it’s left to heal by secondary intention. This approach allows granulation tissue to fill the defect, followed by contraction and epithelialization, though it takes longer and often leaves more scar and drainage. Other factors like time of day, season, or even age may influence overall healing speed, but they don't determine the method as much as the wound size and tissue loss.
