What type of wound closure has a faster rate of healing?

  1. Secondary intention

  2. Tertiary intention

  3. Primary intention

  4. Delayed primary intention

The correct answer is: Primary intention

Wound closure by primary intention is the process through which the edges of a wound are brought together (approximated) and secured, allowing for healing to occur directly. This method is typically utilized in surgical wounds or lacerations that can be easily closed, resulting in minimal scarring and a faster overall healing rate compared to other methods. In primary intention, the body has a more direct path to heal as it does not need to fill in a significant defect or tissue gap, thus facilitating quicker re-epithelialization and closure. The wound is maintained in a clean, approximated state, which also reduces the risk of infection that can prolong healing time. In contrast, secondary intention involves leaving the wound open, allowing it to heal from the inside out, which generally takes a longer time due to the larger amount of tissue that needs to regenerate and fill the wound space. Tertiary intention refers to wounds that are initially left open and are then closed later after a period of observation, which can delay healing further. Delayed primary intention is similar to tertiary intention, where a wound is allowed to heal for a time before being closed, which is also not as expedient in terms of healing rate. Thus, primary intention leads to the
