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

OBJECTIVE

To describe a medial orbital reconstruction using titanium mesh after surgical excision of a multilobular osteochondrosarcoma (MLO) in a dog.

STUDY

DESIGN

Case report.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

CLINICAL SIGNIFICANCE: Titanium mesh can be used to reconstruct the medial aspect of the orbit in dogs.
