The investigators hypothesize that everting wound edges while suturing surgical sites will result in more aesthetic scars. Additionally, we also hypothesize that small to moderate wound irregularities present at 3 months will resolve by 6 months after surgery with no intervention

Condition Intervention
Basal Cell Carcinoma
Squamous Cell Carcinoma
Procedure: Everted suture technique
Procedure: Non-everted suture technique

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Eversion in Dermatologic Surgery: Is Cosmetic Appearance Improved?

Primary Outcome Measures:
  • Everted versus non-everted suturing techniques [ Time Frame: 3 and 6 months ]
    Primary outcome measures for this study are the post operative scar width measured at 1 cm from the midline on both sides of the scar.

  • Mean score of sum of 2 blinded observers POSAS scores [ Time Frame: 3 and 6 months ]
    The mean summed total of two blinded reviewers Physician Observer Scar Assessment Scale (POSAS) scores for each side of the wound.

  • Scar measurements (height, width, length) [ Time Frame: 3 and 6 months ]
    Scar volume will be measured in centimeters on both sides of the wound

  • Scar induration [ Time Frame: 3 and 6 months ]
    Scar induration area will be measured in centimeters for both sides of the wound

  • Scar erythema [ Time Frame: 3 and 6 months ]
    Scar erythema area will be measured in centimeters for both sides of the wound

  • Wound contour irregularities [ Time Frame: 3 and 6 months ]
    Wound contour irregularities will be measured in terms of volume in cubic centimeters via a length, width and height measurement

  • Stand cone volume [ Time Frame: 3 and 6 months ]
    The volume of standing cones will be measured via length, width and height measurements in centimeters

  • Uneven edge measurement [ Time Frame: 3 and 6 months ]
    The area of uneven edges will be measured via a length x height measurement in centimeters

  • Hyperpigmentation area [ Time Frame: 3 and 6 months ]
    areas of hyperpigmentation will be measured via a length x width measurement in centimeters

Secondary Outcome Measures:
  • Infection [ Time Frame: up to 6 months ]
    Infections occurring anytime during the study period will be recorded

  • wound dehiscence [ Time Frame: up to 6 months ]
    incidence of wound infection will be recorded anytime during the study period

  • spitting sutures [ Time Frame: 3 and 6 months ]
    spitting sutures will be counted for each side of the wound at 3 and 6 months

Enrollment: 50
Study Start Date: January 2012
Study Completion Date: September 2014
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Everted suture technique
Technique that everts the skin; the edges will sit up against each other in a little peak, raised above the surrounding skin.
Procedure: Everted suture technique
Active Comparator: Non-everted suture technique
Surgical wound will be approximated such that the suture line is flat relative to the surrounding skin.
Procedure: Non-everted suture technique
