Ms. Corva brings up two excellent points about the article. First, the photo in the article does appear to show a poor approximation of the wound. This is a demonstration of my poor photography skills rather than the wound closure itself The left side of the wound appears to be poorly approximated but I assure you this is an effect of the photo. There is actually some oozing blood which affects the appearance of the photo.
Secondly Ms. Corva is absolutely correct when she points out that cosmetic outcome should be paramount in the consideration of wound closure technique. Especially in children, the most commonly asked questions I receive is "Will this hurt?" and "Will this scar?". Even a cursory search through the literature will reveal hundreds if not thousands of studies on the topic of scaring after wound closure. One that I found particularly helpful was in Pediatric Emergency Care (June 2002) Which specifically compared the cosmetic outcome of scalp repair in children with the use of staples versus traditional sutures. This particular study demonstrated "No significant difference" in cosmetic outcome after 1 year exam.
In fact, further research into the factors affecting outcome of laceration one would find that the actual closure of the wound is the least important part of the procedure. The most important part of the procedure is the exam, cleansing, and preparation prior to closure. Also the incredibly vascular nature of the scalp lends toward excellent healing which is why surgical staples have become so popular in this instance.
