Advantages and important pointers
I have used the punch grafts in pockets technique in such wounds as an axillary wound in a dog and a wound over the nasal
bones of a dog (Figures 2A-2C). The granulation tissue pockets hold the grafts in place as they revascularize and heal. The pockets regress as the grafts
heal in place, and epithelium spreads from the grafts to provide further wound coverage.
Figure 2B. The dorsal nasal area of the dog in Figure 2A after punch grafts have been placed in pockets.
Because the granulation tissue of the pocket is the bandage for the grafts, it is necessary to have a restraint, such as an
Elizabethan collar, to prevent wound molestation as the grafts heal. If a scab forms over the grafted wound, it should not
be disturbed; it serves as a bandage. Remember, although wound closure is provided, the cosmetic appearance of the wound will
not be as good as with other forms of reconstruction.
