The use of a sling suture for ventral orbital stabilization after inferior orbitectomy in three dogs.

OBJECTIVE

To describe a novel surgical technique for the ventral stabilization of the orbit after inferior orbitectomy by using a sling suture and report outcomes in three dogs.

ANIMALS: A 7-year-old male neutered Swiss shepherd, a 4-year-old female neutered golden retriever and a 9-year-old female neutered Rhodesian ridgeback.

STUDY

DESIGN

Short case series.

METHODS

All dogs presented with caudal unilateral maxillary masses. Surgical resection necessitated a caudal maxillectomy and inferior orbitectomy with a combined dorsolateral and intraoral approach. A sling suture was used to support the globe. A nylon suture was placed rostrally through the osteotomized maxilla and caudally through the osteotomized zygomatic arch via predrilled holes. The suture was tightened until the position of the globe subjectively appeared normal and was secured with a surgeon's knot. The periorbita was secured over the nylon suture with poliglecaprone suture material in a simple interrupted or continuous pattern. The surgical approach was routinely closed.

RESULTS

Follow-up ranged from 7 to 63 days. The surgical wounds healed uneventfully, and no postoperative complications associated with the stabilization technique were noted. No orbital deviation was noted and the zygomatic regions appeared subjectively symmetrical.

CONCLUSION

The nylon sling suture provided a quick, easy, safe and effective technique to stabilize the ventral orbit during a combined maxillectomy and orbitectomy in dogs.
