Improvement of postoperative scar appearance
Tidsramme: 3 months
|
To evaluate whether intraoperative fractionated CO₂ laser treatment of surgical wound edges improves postoperative scar appearance compared with untreated wound edges following Mohs micrographic surgery.
Evaluating the perspective of the scar from both the patient and medical professional using the Patient and Observer Scar Assessment Scale (POSAS), which evaluates scar quality.
Using a scale of 1-10, where 1 is "like normal skin" and 10 is the "worst imaginable and using verbal feedback from patients about the appearance of their scars.

Scar Appearance
Tidsramme: 3 months
|
To assess patients overall satisfaction with scar appearance.
This will be done verbally with patients stating they are "satisfied, somewhat satisfied, or not satisfied".

Physician Scar Assessments
Tidsramme: 3 months
|
A group of blinded medical professionals will assess the treated and untreated scar using several standardized assessments.
The first is the Patient and Observer Scar Assessment Scale (POSAS), which evaluates scar quality.
Using a scale of 1-10, where 1 is "like normal skin" and 10 is the "worst imaginable.
The second is the Vancouver Scar Scale (VSS).
This scale evaluates scars across 4 physical characteristics using a score range of 0-13, where 0 represents normal skin and 13 represents the most severe scarring.
Finally the third assessment is the Global Aesthetic Improvement Scale (GAIS).
This scale looks at how much better the patient looks compared to pre-surgery.
This scale uses a scoring range of 1-5, where 1 represents exceptional improvement and 5 represents worse.

Clinical Safety and Healing Outcomes.
Tidsramme: 1 week, 1 month, 3 months
|
To evaluate the safety of intraoperative fractionated CO₂ laser treatment, including healing time and complication rates.
During the follow up visits the physician will do conduct a visual assessment for presence of any infection, dehiscence, poor wound healing.
The physician will use a global assessment of 1-5 and the formal Patient and Observer Scar Assessment Scale (POSAS), which evaluates scar quality.
Using a scale of 1-10, where 1 is "like normal skin" and 10 is the "worst imaginable.
