VSR 421: Regional Veterinary Surgery (2+1)

OPERATION PROCEDURE

• Make an incision about three inches long antero-inferior border of the wing of the atlas, going through the skin without making dissection  the parotid gland. Reflect the gland forward by blunt dissection of the loose connective tissue beneath it.
• Separate the areolar tissue, digastricas, stylo-maxillary and occipito-styloid muscle until the pale lining of the pouch is visible. Grasp a fold of the guttural pouch membrane with an artery forceps and incise it .
• Enlarge the opening thus made with the fingers or the jaws of a forceps and the interior of the pouch will then be quite visible. Evacuate the contents which may be entirely liquid or partly solid in the form of chestnut-like bodies called chondroids.
• To provide better drainage,  a counter opening is made  in the center of Viborg’s triangle.  This is defined as the tendon of sternomaxillaris muscle, the sub maxillary vein  and the caudal border of the vertical ramus of the mandible.
• Pass a stout metal sound into the pouch and make it bulge the skin in the center of the triangle. Keep this opening patent for a few days by inserting a strip of gauze through it and the upper opening.
• The surgical wound heals by granulation.
