Zusammenfassung: | BACKGROUNDPatients are often concerned about the cosmetic appearance of scars following Mohs micrographic surgery (MMS), including residual erythema. However, few studies have compared the cosmetic outcomes between different suturing techniques.
OBJECTIVETo compare the erythema intensity (EI) associated with interrupted sutures (IS) and continuous sutures (CS), and the degree of its reduction over time.
MATERIALS AND METHODSMohs micrographic surgery patients were randomized to have half of their defect repaired with IS and the other half with CS. Postoperatively, subjects were assessed at 1 week, 2 months, and 6 months and close-up photographs of their scars were taken. Computer-assisted image analysis was utilized to quantify the EI in each half-scar.
RESULTSThe average EI of IS was greater than that of CS by 9.3% at 1 week (p < .001) and 7.2% at 2 months (p < .021) but comparable at 6 months. These differences were clinically detectable, but EI differences resolved by 6 months in most cases. At 6 months, EI regressed by 33.5% in IS and 26.3% in CS.
CONCLUSIONContinuous sutures are associated with less erythema during early scar maturation but are comparable to IS at 6 months. These results may guide the choice of suturing technique to improve early cosmetic outcomes and overall patient satisfaction. |
