Skin Subs vs Secondary Intention
11. mai 2026 oppdatert av: Baylor Research Institute
Skin Substitutes Versus Secondary Intention Healing After Mohs Micrographic Surgery
The purpose of this study is to compare two ways of caring for wounds after Mohs micrographic surgery (MMS) for skin cancer using skin substitutes and secondary intention healing, to determine which option leads to better healing after Mohs surgery.

Detaljert beskrivelse
This is a randomized-controlled trial comparing two ways of caring for wounds after Mohs micrographic surgery for skin cancer: skin substitutes, which are special wound-healing materials that may help wounds heal, and secondary intention healing, a common method in which wounds are allowed to heal on their own.
This research is being done because we do not yet know which option leads to better healing after Mohs surgery.
Patients will be randomized into one of two groups and receive either the skin substitute or undergo secondary intention healing.

Cosmetic Outcome Assessments
Tidsramme: 12 weeks
|
Compare cosmetic outcomes at 12 weeks between wounds treated with (1) a skin substitute and (2) secondary intention healing alone.
This will be done by a group of blinded independent reviewers using standardized photographs and 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".

Tidsramme |

Complete Wound Healing
Tidsramme: 12 weeks
|
Assess the amount of time to took for the wound to heal completely, also defined as full epithelialization.
This will be compared using a t-test model or the Mann-Whitney U tests.
A t-test model uses an standard statistic test that is used to determine if there is significant differences between two groups.
The Mann-Whitney U tests is a rank-sum test that is used to determine if there is a difference between two different groups.

12 weeks

Pain Scores
Tidsramme: 12 weeks
|
Evaluate the patient-reported pain during the first 2 weeks of healing and weekly, at follow-up visits, until wound closure.
Patients will verbally rating their pain on a scale of 1-10 where 1 is no pain and 10 is severe pain.
Patient will keep a record of their daily pain levels and share the scores at their weekly follow-up visits.
|
12 weeks
|
|
Rate of Complications
Tidsramme: 12 weeks
|
To determine the rate of complication and assess for infection, bleeding, hypergranulation, and unplanned interventions.
During the follow-up visits the physician will conduct a visual assessment for these items and will use a chi-square or Fisher's exact tests.
A Chi-Square test is a statistical tool that is used to determine if there is a different between expected and observed frequences in one or more category.
Fisher's exact test is a tool used to determine if there are non-random associations between two categorical variables.

Scar Appearance
Tidsramme: 12 weeks
|
To evaluate the patient-reported scar satisfaction by patients 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".
