RESUMO
OBJECTIVE: To report reconstruction of a defect of the nasal plane and the rostral dorsum of the nose in a dog using a nasal rotation flap with Burow's triangles. STUDY DESIGN: Clinical report. ANIMALS: Mixed-breed dog (1.5 years, 8.6 kg). METHODS: A nasal defect caused by chronic granulomatous inflammation and involving the lateral nasal plane and adjacent rostral nasal dorsum in a dog was reconstructed and closed using a unilateral nasal rotation flap incorporating dorsal nasal plane tissue, with excision of Burow's triangles. RESULTS: The modified unilateral nasal rotation flap was effective in closing a defect of the rostral nasal dorsum. Incorporation of dorsal nasal plane tissue in the flap allowed for a cosmetic reconstruction of the lateral nasal plane defect (wing of nostril). CONCLUSIONS: Skin defects on the rostral dorsum of the nose and defects of the nasal plane in dogs can be closed and/or reconstructed using nasal rotation flaps incorporating nasal plane tissue.
