Scanning Electron Microscopy of the Tracheal Epithelia. a Five days after surgery in the control group. b Five days after surgery in the inverted group. a, b The epithelium in the treated segment was denatured. Arrowheads indicate disengaging epithelial cells. c Two months after surgery in the control group. d Two months after surgery in the inverted group. c, d The ciliated epithelium was well recovered
