Injecting ethmoid hemotoma with 10% buffered formalin (image)

With the use of an injection needle the ethmoid hematoma was penetrated and infused with 40cc of formalin until it became turgid. The animal will be rechecked in 2 weeks and have the procedure performed again if needed. We may have to perform this procedure 2 to 8 times at 2 week intervals depending on the mass size.
