Treatment of canine aural hematoma with an indwelling drain

Aural hematomas in 9 dogs were managed by manual expression through stab incisions in the pinna and placement of indwelling silicone rubber drains, without compression bandaging. The drains were well tolerated. Seromas developed in 2 ears when the drains were removed at 7 and 10 days, but the seromas resolved when the drains were replaced. Healing without deformation of the pinna was obtained when the drains were maintained 13 to 28 days.
