One of the determinants of a successful surgical outcome is the perception, on the part of the patient, of the cosmesis of a scar. The use of Z-plasty is an accepted means by which to break a scar up into smaller geometric segments. In some instances, a Z-plasty is used for scar revision to elongate a scar that may be pulling. However, a study published online in JAMA Facial Plastic Surgery on April 7 mentions the lack of studies measuring the perception of these scars among the normal population after surgery.
Ratnarathorn et al designed a prospective Internet-based survey with a goal of 580 responses to give a power of 90%. The survey was distributed to a diverse sample of the US population. Using editing software, Ratnarathorn et al superimposed a mature linear scar and a mature zigzag scar onto the faces of standardized headshots from 4 individuals (2 males, 2 females). Each individual had 1 image of the linear scar and 1 image of the zigzag scars superimposed onto each of 3 anatomical areas—forehead (flat surface), cheek (convex surface), and temple (concave surface)—yielding 24 images for the respondents to assess.
A 24.5% (n=876) response rate was achieved with 3575 surveys distributed. Of the 876 respondents, 810 (92.5%) completed the survey (46.1% male, 53.9% female). Respondents were asked to rate the scars on a scale of 1 to 10 (1=normal skin; 10=worst scar imaginable).
Results were statistically significantly lower (better) for the linear scars compared to the zigzag scars in all 3 anatomic areas and across both male and female groups with a mean score of 2.9 versus 4.5 (P<.001). A multivariable regression model of respondent age, sex, educational level, and income showed no statistically significant effect on the rating of the scars.
What’s the issue?
This study highlights some interesting points. Coming from an academic practice, we oftentimes find ourselves teaching residents a variety of skin closure techniques to deal with defects from skin cancer excisions. It is both challenging and fun to design complex closures; however, we must keep in mind what is in the best interest of the patient. One of the points I try to emphasize is that we must understand that there are no true straight lines on the face. In fact, when scars from procedures appear as geometric shapes on the face, our eyes tend to be drawn to them. For this reason, it often is best to use curvilinear lines wherever possible. Ratnarathorn et al highlights that point exactly. More studies of this nature are needed to assess what is perceived as a successful outcome, by both physicians and patients.
As you follow your patients for the long-term, have you noticed that you perform more or fewer zigzag scars?
