Mass on lip - implantation

Credit: Moses Brennan, BVSc CertES(Orth) MRCVS, Rainbow Equine Hospital

5 x 15cm mass on the upper lip of a grey mare requiring marginal excision without causing major distortion of the lip.

2 v45-27 expanders were placed on the lateral side of the mass and one v45-27 expander was placed medially side via an incision proximal to the mass. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

The mass was resected, and the expanders removed through the same incision. The tissue was debrided using a hydrosurgical system.

The expanded tissue was used to close the resulting defect with minimal distortion of the contour of the lip.

Periocular mass

3 x 3cm pedunculated mass on the upper eyelid of a 7 year old mare with plans to remove marginally with a wedge resection and avoid distortion of the upper eyelid.

Two v45-27 expanders were placed lateral to the mass via a proximal incision. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect

Non-healing wound on dorsal cannon

5 x 15cm granulated wound over the dorsal cannon bone of a black gelding requiring closure.

6 v45-27 expanders were placed on the lateral side of the wound in two rows and three v45-27 expanders were placed on the medial side via a proximal incision. Blunt dissection of the subcutaneous tissue was used to create the pockets. A distal incision was made to facilitate dissection of the distal aspect of the pockets.

The wounds were closed with a two-layer closure.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Rectovaginal fistula - implantation

Expansion was used to create additional tissue to reconstruct a 7 x 7 cm rectovaginal fistula in a mare. Previous attempts at repairing the defect had failed as the result of wound breakdown.

Expansion was used to create additional tissue to reconstruct a 7 x 7 cm rectovaginal fistula in a mare. Previous attempts at repairing the defect had failed as the result of wound breakdown. Two v45-27 expanders were placed cranial to the fistula and one v45-27 expander was placed caudal to it via incisions in the rectal mucosa.

The wounds were closed in an interrupted pattern with a monofilament suture material. The expanders were left in place for 14 days.

The edges of the fistula were debrided from a rectal approach and the expanders removed through the same incision.

The rectal and vaginal mucosa were separated by blunt dissection beyond the expanded tissue. The expanded mucosa was then used to close the defect.

Tissue expansion is commonly used in human reconstructive surgery to grow extra skin through controlled mechanical overstretch.
