Leveling SutureApproximate—Do not StrangulateIf you are not happy with the suture, cut it out and replace with a better suture!

SUTURE, LOAD LEVELING

Keloid and other Intralesional injections

Mixture: Kenalog 10(Kenalog 10mgs/cc) and lidocaine 1:1; usually about 0.25 cc:0.25 cc.Use fine needle; 27 to 30 guage needleLuer-lock preferredInterval: usually 6-12 weeksKeloid: Do not attempt re-excision until patient has received 3 injections

Advanced Closures

Z-Plasty

Z-Plasty

Good Choice for:o Pilonidal Cyst Scar or sinuso Repair over a joint (finger)

Dog Ear Correction

Dog Ear Correction

Good Choice for:o Any repair or elective excision where you

have too much skin on one side of the repair that will immediately or ultimately result in a Dog Ear Deformity.

Single Advancement Flap

Double Advancement Flap

Single and double Advancement Flaps

Good Choice for:o Backo Thigho Abdomeno Calf, maybe

Rotation Advancement Flap

Rotation Advancement Flap

Good Choice for:NeckScalpFaceAnywhere where you have loose skin adjacent to an area that is “tight” or where there is limited skin for a flap or “good closure” without undue stress

M-Plasty

M-PlastyGood choice for:

o Scalpo Faceo Armo Leg o Footo Ankleo Almost anywhere (especially where there is limited

skin to flap)

Triple U Plasty

Triple U Continued

Triple U Conclusion

Triple U-Plasty

o Good choice for:o Noseo Necko Ear

V to Y Slide 11. Circular Defect

2. Plan triangle, using skin lines

V to Y Slide 23. Incise the triangle,

then undermine thoroughly.

4. Thin base of triangular flap to fit defect.

V to Y Slide 35. Remove triangle

6. Suture base.

V to Y Slide 47. Suture long limb.

8. Close remaining incisions.

V to Y Plasty

Good choice for:o Inferior Orbital areao Pre-auricular area

Coding & BillingCoding and billing becomes very complex for laceration repair and excisions. Important factors to list for billing personnel are:

LocationSize of lesionLength of closure or excisionSimple or intermediate repairBenign or malignant statusWhether a true skin lesion or subcutaneous tumor or deep tumor was excisedMethod of removal

Coding & Billing continuedSuture removal is included in the initial charge if the original sutures were placed by the same group of physicians. Suture removal can be billed if performed by an unassociated physician or group. Anesthetic, materials and supplies are customarily also included in the reimbursement fees. If a lesion is excised and repaired in a simple fashion (no undermining, deep sutures, flaps, or plasties), the fee for excision includes repair and suture removal.

VERTICAL MATTRESS SUTURES: VARIANTS

Far-Far/Near-NearNear-Far/Near-FarFar-Near/Near-FarNear-Far/Far-NearSpace-ObliteratingPulley or LoopHalf-Buried

Vertical Mattress: Classical, Far-Far/Near-Near

Vertical Mattress: Classical, Advantages

Everts Skin EdgesReduces Wound TensionEliminates dead spaceProvides a strong closure

Vertical Mattress: Classical, Disadvantages

Potentially StrangulatingMay compress the skin adjacent to the defect causing: scarring

focal necrosisPostoperative edemaTake a little more time

than running suture

Vertical Mattress: Near-Far/Near-Far

Near-Far/Near-Far Mattress, Vertical: Indications

Promotes Skin EversionUseful for elevating the deep tissues of a wound

Vertical Mattress: Far-Near/Near-Far

Far-Near/Near-Far Mattress, Vertical: Details

Almost identical to the Near-Far/Far-Near suture except, the knotted suture segment connects the two far points as opposed to the 2 near points.

Vertical Mattress: Near-Far/Far-Near

Near-Far/Far-Near Mattress, Vertical: Details

Described as a combination suture of traditional vertical mattress and interrupted sutureMain use where tension exists on thin skin including the eyelids and parts of the scalp.Also, creates a pulley effect which may be very helpful when significant tension exists at the time of closure

Vertical Mattress: Space-Obliterating

Space-Obliterating Mattress, Vertical: Details

Involves an additional loop within the dermisProvides a pulley effect to the closureThought to distribute tension more evenly over a larger areaGenerally work where there is considerable tension at time of closing

Vertical Mattress: Pulley or Loop

Pulley or Loop Mattress, Vertical: Details

Suture works as a PulleyProduces less tension on either of the suture strandsThus reduces pressure or impingement on the skin surfaceAlso, reckoned as a very strong closure where tension exists at time of closing

Vertical Mattress: Half-Buried

Half-Buried Mattress, Vertical: Details

Placed in a traditional far-far/near-near sequenceBut the needle does not pierce the skin surface opposite the starting pointChief Advantage: Less scarring and less likelihood of strangulationApproximates edges well, but may not relieve wound tension as wellUseful on lip, eyelid, or hairline

REVIEW SUMMARY

1. Review the Basics2. Review the options for Closure

before removal of lesion3. Make the Advanced Closure “Fit the

Site”

4. Acrostic:Corner SuturesUndermineBurow’s TrianglesExtension

5. Self-RefreshersWork on Pigs feet every 3-6 months

REVIEW SUMMARY (cont)6. Overview:

A. Vision- Visualize, in your mind, the finished product!

B. Technical- Holder yourself to ahigher standard to place every suture in the “right place”

C. Flexibility- When things don’t work out just right or look just right----make revisions then to obtain the result the best it can be.
