Description The present clinical study on reconstruction of skin defects using skin grafts was performed on nine dogs with 12 wounds, in Dept. of Surgery and Radiology, Rajendranagar, Hyderabad and Campus Veterinary Hospital, Bhoiguda, Secunderabad. Following clinical examination, the 12 wounds from nine dogs, that were unnamable to primary closure, were selected for the present study irrespective of breed, sex and age.
In these nine dogs, with twelve wounds, five wounds resulted following tumour excision and seven wounds that resulted from trauma. Out of the five dogs in which tumour excision was performed, two wounds resulted from excision of mammary tumour for which cranial epigastric axial pattern flap was used in both the dogs. One wound each resulted due to excision of a tumor on the lateral aspect of the ear pinna, tumor excision from the middle digit of the right forelimb

and tumor excision below the hock joint, for which caudal auricular axial pattern flap, pinch graft and reverse saphenous vein conduit flap respectively were used. The seven traumatic wounds were present in four dogs. One dog was operated for wounds on both the elbows, one with pinch graft and one with thoracodorsal axial pattern flap, following several unsuccessful attempts to encourage second intention healing at different hospitals. One dog was presented with a large traumatic wound on the left lateral aspect of the neck, which was treated with omocervical axial pattern flap, one dog was presented with three wounds on both the hind legs and the wounds were surgically reconstructed using pinch skin graft, partial thickness mesh skin graft and reverse saphenous vein conduit flap, and one dog was presented with circumferential degloving injury of the left fore limb and was surgically treated using thoracodorsal axial pattern flap.
For the seven traumatic wounds, the recipient bed was prepared two days prior to skin grafting surgery, by scraping off the chronic granulation tissue with a BP blade No. 11. The result was found satisfactory as the fresh granulation tissue appeared beef red in colour on the day of surgery. A general soft tissue surgery set was considered adequate, except for partial thickness mesh skin graft. A Watson’s skin graft knife was used to harvest the skin graft in this technique.
For the two dogs in which thoracodorsal axial pattern flap was employed, one flap eventually necrosed and sloughed off by the 15th post-operative day. In the other pup, the flap was well taken, but the pup was lost to follow-up. The reverse saphenous vein conduit flap employed in two dogs achieved good results, with complete epithelialization and hair growth. The results of the two dogs operated with cranial epigastric axial pattern flap was found satisfactory with no necrosis and signs of complete graft take. Caudal auricular axial pattern flap

and omocervical axial pattern flap employed in one dog each achieved complete graft take with
hair growth noticed by the 18th post-operative day.
For two dogs in which pinch grafting technique was employed, the grafted site healed
well, inspite of one or two pinch grafts floating out of the recipient bed. However, for one dog in
which pinch grafting was employed following tumour resection, the pinch grafts were lost due
to self mutilation. The partial thickness mesh skin graft used for one wound was found
satisfactory, with complete epithelialization noticed by the 30th post-operative day. For the dogs
in which a tubed pedicle was created, the tube was cut close to the body on the 10th postoperative
day.
First bandage change was performed 72 hours following skin graft surgery, and the
subsequent bandage changes were done every alternate day, except in one dog for which the
bandage was changed daily due to high exudate.
It was concluded from the present study that, skin grafting surgeries yield good results for
correction of large wounds or also following tumour excision, irrespective of the technique
employed. Prolonged post-operative care and the need for multiple surgeries may serve as a
hindrance from the owners point of view.
