A dermal adhesive (or skin glue) is a glue used to close wounds in the skin as an alternative to sutures, staples, or clips. Glued closure results in less scarring and is less prone to infection than sutured or stapled closure. There is also no residual closure to remove, so follow-up visits for removal are not required.
2-Octyl cyanoacrylate is a cyanoacrylate ester typically used as a wound closure adhesive (under the brand name Dermabond). [1] It is closely related to octyl cyanoacrylate. The use of 2-octyl cyanoacrylate was approved in 1998; offered as an alternative to stitches, sutures, and or adhesive strips. [2]
Reinforced skin closures: These are sterile skin closure strips that are made of a porous, non-woven backing coated with a pressure-sensitive, hypoallergenic adhesive and reinforced with polyester filaments for added strength. They provide general wound support for increased tensile strength and finer wound edge approximation.
The closure of the wound or cut is quick (about 30 to 45 seconds) and the product has inherently some valuable bacteriostatic properties. The cosmetic outcome of the closure is comparable or generally better than an equivalent suture substitute with least amount of scarring visible after three to six months.
Topical cyanoacrylate adhesives (closely related to super glue), have been used in combination with, or as an alternative to, sutures in wound closure. The adhesive remains liquid until exposed to water or water-containing substances/tissue, after which it cures (polymerizes) and forms a bond to the underlying surface.
In the US, due to its potential to irritate the skin, the U.S. Food and Drug Administration (FDA) did not approve its use as a medical adhesive until 1998 with Dermabond (2-octyl cyanoacrylate). [8] A 1986 independent study suggests that cyanoacrylate can be safer and more functional for wound closure than traditional suturing (stitches). [9]
