What is tertiary intention (delayed primary) healing?

What is tertiary intention (delayed primary) healing?

• A. The wound is immediately closed with primary closure.
• B. The wound is closed after 7-14 days to allow granulation.
• C. The wound is left open with no closure option.
• D. The wound is left open for 3-5 days to allow drainage, infection control, or edema reduction before being closed.

Answer: (D)

Tertiary intention healing, or delayed primary closure, means you don’t close the wound right away. Instead, you leave it open for a short period to allow drainage, reduce edema, and control any infection. After this initial period, the wound is closed once the tissue bed is clean and ready for closure. This approach combines the benefits of rapid wound approximation with infection control, aiming to reduce complications like abscesses or sepsis. Leaving the wound open for a brief window—about 3 to 5 days—before closing fits this pattern, because it provides time for drainage and stabilization before definitive closure. Immediate closure would be primary intention, and leaving the wound open without planning for later closure aligns more with secondary intention. A much longer delay than 3–5 days is not the typical teaching for tertiary intention.
