A Novel Tenorrhaphy Suture Technique with Tissue Engineered Collagen Graft to Repair Large Tendon Defects

Neck contracture release with matriderm collagen/elastin dermal matrix
Aims:
To demonstrate success with immediate split-skin graft application over Matriderm dermal matrix in a difficult neck contracture release.
Methods:
An aggressive neck contracture release, accompanied by complete platysmectomy, was followed by application of Matriderm, split-skin graft, Mepitel, and vacuum-assisted closure (VAC) dressing.
Results:
At VAC removal (day 7), graft take was almost complete over the dermal matrix and with minor "touch-up" were complete by day 9 postrepair. RESULTS at 4 months show graft contraction and a marked diminution of the release obtained. The results, however, are still good and the patient is very happy.
Conclusion:
Immediate grafting over a dermal matrix appears to provide a good solution, with a gentle surgical learning curve, in this difficult postburn scenario. Postrelease contraction is, however, as inevitable as with other techniques.
