Medial Orbital Reconstruction After Removal of Multilobular Osteochondrosarcoma (MLO) in a Dog.

Abstract

<h4>Objective</h4>To describe a medial orbital reconstruction using titanium mesh after surgical excision of a multilobular osteochondrosarcoma (MLO) in a dog.<h4>Study design</h4>Case report.<h4>Methods</h4>A 9-year-old, castrated, male Siberian Husky was treated for left orbital MLO causing left enophthalmia and lateral displacement of the left globe. A surgical excision was completed, with preservation of the globe. The medial orbit was reconstructed with titanium mesh.<h4>Results</h4>The patient recovered uneventfully. Histopathology confirmed MLO, grade II with complete excision. At the 2-week follow-up, there was persistent mild enophthalmia, but the patient was asymptomatic. No thoracic metastasis, local recurrence or enophthalmia was noted at the 6 months recheck.<h4>Conclusion</h4>The use of titanium mesh restored the medial orbit and provided excellent functional and cosmetic outcomes. No major complications were noted up to 6 months postoperatively.<h4>Clinical significance</h4>Titanium mesh can be used to reconstruct the medial aspect of the orbit in dogs.
