[Evaluation of survival of the pedicle flap by polarographic method]

The data obtained by the authors allowed the use of a polarographic study of pO2 in the pedicled graft tissue as an adjunct method of determining the graft patency. This method may be especially valuable in cases of a complicated period after suturing the graft to a defect, when considerable difficulties arise as to finding the optimum terms for a safe incision of the feeding pedicle.
