Ok guys I brought in a Rhino Iguana he needs some work.. He's underweight, has a bad attitude... And a damaged ear.

On his left ear the bottom tissue is all there but it is loose/tissue is broken off on about 1/4th of the ear drum tissue. I was advised to put some neosporin on there to keep it from being infected and wait for it to naturally heal.. so far it has not. Its vet time but does anyone else have any ideas (just incase I run into this again in the future?).
