More toxic than active infection?

Usual referral centre dogmatic nonsense. Next.

I was informed at a Dick White Referral Centre CPD course that anything is potentially toxic once into the wrong side of the ear drum. ? Any medications can be harmful there. I think that sterile saline is the safest option to flush out as much pathogenic organisms or debris s possible. However, being a fungus, does Malassezia not thrive best in damp donditions? If so how does one dry the area both effectively and safely?

[as a mini-tangent] How common is bedlington liver disease these days since genetic testing?

Another vote for topical antifungals then cortavance

I find Recicort to be useful to prevent recurrences if there's primary allergic skin disease. It has the usual contraindication with ruptured tympanic membranes, but I don't think it is specifically thought to be ototoxic.

Wasn't around in my day. how does the potency compare with other topical Csteroids?

Doesn't the patient mind being aurally sprayed?

Local Csteroids depressed production of sebum and the growth of malasezzia so the problem went away [with concurrent ear mite treatment usually!!]

It sounds as if this animal has the traditional allergic scenario??

I would tend to agree, I have found that Apoquel and Cytopoint often don't completely control ear lesions in dogs with allergic skin disease, and I have used Cortavance Spray in the ears once or twice a week with good results.

We always understood that malasezzia was a commensal which overgrows parallel to the amount of sebum [in an allergic or irritated ear canal].

For what it's worth, which I allow is not very much, I have used clotrimazole in many an ear with ruptured tympanum, have even infused it (as part of mixed medicament) into the middle ear, without adverse effect.

Whereas chlorhexidine is notoriously ototoxic.

I can't find where I have it written, so only going by memory, but I understood that the canesten solution is ok to use if TM not intact. The data sheet for humans mentions it is particularly useful for otitis externa and middle ear infections.

I think there may be a genetic test for Bedlingtons re risk of hepatopathy if considering systemic azole.

Vetruus said " reports of it being used in dogs with ruptured TM, without issues" but isn't licensed.

They said, definitely don't use in cats with suspected TM rupture.

I believe that Otodine is safe to use in the case of a ruptured ear drum and is indicated to treat malassezia and staph infections. May be worth speaking to Vetruus about it.

[/quote]ah, that's the second time I have heard that...we are awaiting a reply from vetruus so I will up date the thread.

You could have read my mind, because I was going to ask a similar question today

Our son had ear drums torn for 19 years. They never healed and it is only now that they have been surgically patched that they will hopefully remain so. My understanding from an ENT surgeon friend is that many simply don't heal. So how can we expect a dogs to fix and I was going to ask, how many dogs ear drums do actually heal
