Large surgical defects can lead to significant suture tension upon closure despite undermining.
Herein we describe a novel and useful technique of fat plication to reduce closure tension. This
technique works best in areas with fibrous fat septae such as trunk and proximal limbs, although
some areas of the head and neck also provide adequate tissue strength. After minimal undermining,
a 3-0 polyglactin 910 suture on a PS2 needle is inserted horizontally into the fat at the most lateral
point of the undermined tissue. The needle is then guided in a horizontal arc through the fat and
fibrous septae to exit at the same level. The second throw then enters the fat on the direct opposite
edge and at the same depth (Figure 1). After exiting the fat, the suture is tied to bring the wound edges closer (Figure 2). The goal of these sutures is to close 2/3 to 3/4 of the defect width rather than in tight apposition. Full closure with this suture may place excess tension on the fibroadipose tissue. After narrowing of the adipose plane is completed, subsequent buried dermal sutures are placed
under significantly reduced tension in the plane above.
Although other closure techniques in high tension areas such as fascial plication [1] and butterfly suture [2] have been described previously, fat plication provides an additional subdermal option dependent on the presence of adequate fibrous adipose tissue. This method utilizes the abundant
fibroadipose tissue located in the trunk, proximal extremities, and lateral cheek. Areas known to have minimal fibrous septae such as hands, feet, and scalp are not good
locations for this technique. We believe that fat plication provides
at least equal efficacy in decreasing dermal and epidermal tension as
compared to other previously described methods. In addition, this
method of plication provides advantages when compared to butterfly
sutures and fascial plication. In butterfly sutures, there is a risk of
hypereversion and dimpling of the skin surface. Fascial plication is
limited by the fascia’s deep location in many areas such as the trunk
and potential pain associated with sutures that may encounter muscle
fibers. With fat plication, less undermining is required as the sutures
themselves hold more tension. We believe that fat plication provides
a secure and reliable method of supporting wound tension in many
areas.
