Cyanoacrylates for skin closure

Cyanoacrylates (CAs) were not widely adopted for medical use until recently because of lingering concerns regarding the initial tissue toxicities of the short-chain CAs. The medium-chain CAs, primarily butyl-cyanoacrylate, have been widely used in Europe and Canada for several decades and have gone a long way in dispelling any lingering concerns about tissue toxicity. The newer, longer chain CA, octyl-2-cyanoacrylate (2-OCA), now has been approved for multiple uses in the United States and has achieved widespread acceptance by the medical and lay communities. The current authors believe that this is probably only the beginning of the use of 2-OCA and other CAs in cutaneous medicine. This article discusses the use of CAs in their original cutaneous use as glues for the repair of lacerations and incisions and in their more recent use as dressings for the treatment of abrasions and wounds.
