Suspension suture
Suspension suture
This is a niche technique designed to fix one or both edges of a defect to a deeper structure. This approach has also been referred to as a pexing suture or tacking suture, and is utilized typically in several situations. First, when repairing a defect that crosses a natural sulcus, it is important to tack down the skin overlying the sulcus so that the natural depression is not blunted, or bridged, by the repair. Second, it is used when working near cosmetic subunit boundaries and free margins, to avoid functional challenges such as ectropion and eclabium, as well as cosmetic distortion of sensitive areas such as the lip and eyebrows. It is also useful in order to fix a flap in place and minimize tension on the distal portion of the flap. Finally, this approach may also be used to prevent nasal valve collapse in the appropriate setting (Fig. 13-7).
