What is the most commonly associated injury with a Lefort I fracture?

Le Fort fractures may be associated with other injuries such as dental or alveolar ridge fractures (alveolar and palatal fractures are commonly associated with all types of Le Fort fractures and make the repair more difficult and complex), cerebrospinal fluid leaks, and severe epistaxis.

What is the maximum time a facial wound closure can be extended?

What is LeFort 2 fracture?

Definition. The Le Fort II fracture is also referred to as a pyramidal fracture. It commonly extends from the pterygoid plate through the maxilla, through the nasal orbital ethmoid area, and nasofrontal bone.

What is the golden period of wound healing?

The first 6-8 hours after a wound is called the “golden period” because clinical studies show that there are less than 105 organisms/gram tissue within that time and so the wound can be closed safely.

How long is too long to close a wound?

Your risk of infection increases the longer the wound remains open. Most wounds that require closure should be stitched, stapled, or closed with skin adhesives (also called liquid stitches) within 6 to 8 hours after the injury. Some wounds that require treatment can be closed as long as 24 hours after the injury.

Which type of suture should be used to close an infected wound?
