Abstract
ObjectiveTo investigate the clinical efficacy of bilayer artificial dermis of tissue engineering products for repair of fingertips and nail bed defects.
MethodsFrom May 2017 to May 2019, 33 cases of 46 fingertips and nail bed defects with distal phalanx exposure were treated. After debridement, bilayer artificial dermis was used for first stage coverage and repair, but no autograft was used. Two to three weeks after the operation, the bilayer artificial dermis covering the fingertips and nail beds was vascularized to form bright red dermoid like tissue and nail bed like tissue.
ResultsAll the 33 cases (46 fingers) had good vascularization. After the vascularization of the artificial dermis covering the fingertips, the granulation tissue grew well and was naturally epithelialized, with good healing and round and full appearance. After the vascularization of the artificial dermis covering the nail bed defects, the nail bed like tissue was formed, which was smoothly connected with the original nail bed, and the nail grew well and smooth.
ConclusionCompared with the traditional methods, the bilayer artificial dermis of tissue engineering products for repair of fingertips and nail bed defects has the advantages of more simple operation, less trauma and better clinical efficacy, which is worth popularizing and applying.
