Histologic evaluation of biopsy specimens from six split-thickness skin grafts and seven pedicle flaps was made two months to 15 years after intraoral cancer reconstruction. In the transplanted skin, there was persistence of all epidermal layers with production of orthokeratin and melanin, and persistence of papillary and reticular dermis with viable hair follicles and sweat glands. The junction of epidermis and mucosa was distinguished by a strongly positive PAS staining of the mucosal epithelium. There were no differences in the observations on split-thickness grafts and pedicle flaps. After 15 years of exposure to an intraoral environment, "mucosalization" of the skin was not evident.
对6块中厚皮片和7个带蒂皮瓣进行口腔癌重建术后2个月至15年的活检标本组织学评估。在移植皮肤中，所有表皮层持续存在，有正角化蛋白和黑色素生成，乳头层和网状真皮持续存在，有存活的毛囊和汗腺。表皮与黏膜的交界处黏膜上皮PAS染色呈强阳性。中厚皮片和带蒂皮瓣的观察结果无差异。暴露于口腔环境15年后，皮肤的“黏膜化”不明显。
