In this case, the hamster kept scratching his left ear and came in for surgery on Oct 9, 2013. From my observation, I told the husband that the ear might need to be cut off. Dr Daniel handled the surgery and removed the wart, putting in two 4/0 nylon stitches. Sedation with Zoletil IM. The hamster woke up 30 minutes later. Image of him on a "mouse" was taken 15 minutes after surgery.
Will the hamster still scratch his left ear? There are 2 stitches. As each vet has his or her own approach to surgery, I would not say my approach would be the better. In my approach, I would excise the wart and used KMnO4 powder to cauterise the wound. Or I would use electro-cautery. That would mean no stitches which could irritate the hamster again and would need removal in 10 days' time.
