Abstract

PICO question

In dogs with aural haematomas does draining and injecting corticosteroids versus drainage alone reduce the risk of recurrence?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

Three papers were critically reviewed, a retrospective multi-centre cohort study, a randomised case control trial and an observational survey

Strength of evidence

Weak

Outcomes reported

Drainage alone at daily or weekly frequency consistently resulted in aural haematoma (AH) recurrence and lack of resolution. Corticosteroid instillation alongside drainage reduced the risk of rapid recurrence for AHs, across both the cohort and the case control studies, provided drainage was frequent

Conclusion

The strength of evidence for local steroid instillation was weak given the type of studies reviewed, alongside small sample sizes and variations in treatment protocol. However, consistently drainage alone appears an insufficient means of addressing AHs in dogs.

In cases where frequent drainage was the chosen treatment option, the addition of local corticosteroid application appeared to improve the outcome compared to drainage alone.

However, as systemic treatment was often employed alongside local corticosteroid instillation, success cannot necessarily be attributed solely to local treatment. Larger, randomised control trials would be required to assess the effect of each individual intervention providing clearer evidence for the most effective medical protocol for treating aural haematomas in dogs

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
