Abstract
Intranasal tumors in dogs are rare neoplastic diseases with obvious clinical signs, such as epistaxis, nasal congestion, and facial deformity. Radiation therapy is the treatment of choice but is not always accessible due to geographical location, logistics, or financial constraints. Other treatments may not be used because of various restrictions. We performed transnasal intranasal tumor volume reduction in 2 dogs with intranasal tumors; 1 dog had an adenocarcinoma and the other had a fibrosarcoma. In both cases, improvement in the quality of life (QOL), including reduced clinical signs and increased activity, was observed ~1 wk after treatment. No obvious complications were associated with this treatment. Although tumor recurrence was noted in both cases, this treatment could be applied multiple times. In conclusion, transnasal nasal tumor volume reduction is a palliative method that contributes to improvement of clinical signs and QOL. Key clinical message: We report palliative treatment of intranasal tumors in dogs. The treatment described in this report is available to most veterinarians and helps improve the QOL of dogs with nasal tumors, including improving respiratory status.
