Incisional drainage involves creation of a linear or S-shaped incision with sutures or stents, biopsy punch incisions, or carbon dioxide laser incisions (Henderson & Horne 1993, Dye et al. Drainage techniques including teat cannula, Penrose drain combined with corticosteroids or closed-suction drain have been described (Wilson 1983, Kagan 1983, Joyce 1994, Swaim & Bradley 1996, Pavletic 2015). There are various treatment options for aural haematomas, including needle aspiration with local infusion of corticosteroids, tube drainage or incisional drainage.
#AURAL HEMATOMA DOG SKIN#
Treatment objectives of aural haematomas include identification and control of the underlying cause, provision of adequate drainage and elimination of the space between the skin and the cartilage of the pinna (Lanz & Wood 2004). If the haematoma is left untreated secondary fibrosis and contraction will result in permanent distortion of the pinna. Blood accumulation occurs following separation of the skin of the pinna from the underlying cartilage or within the subperichondral space (Larsen 1968, Dubielzig et al. However, some animals with aural haematomas show no signs of underlying ear disease. Although the exact cause remains unclear, different mechanisms are implicated, including trauma from head shaking and ear scratching secondary to otitis externa, autoimmune disease, other immunological factors or skin hypersensitivity (Wilson 1983, Dubielzig et al. No signs of haematoma were reported after a follow-up time of 3.5 years for dogs and 4.5 years for cats.Īural haematomas are blood collections affecting the concave surface of the pinna and are more commonly seen in dogs than in cats (Lanz & Wood 2004, MacPhail 2016). Cosmetic outcome of the pinna was rated by the owners as good in 26 dogs and 2 cats, as average in 20 dogs and 3 cats and as poor in 3 dogs. Mild pinna thickening or poor ear carriage was diagnosed in 16 dogs and 2 cats. Those animals were treated with placement of a new Penrose tube. Recurrence of haematoma following Penrose removal was reported in 7 dogs and 1 cat. or dermatophytes was diagnosed in 11 dogs and 1 cat.

Otitis externa was diagnosed in 23 dogs and 3 cats and skin disease including atopic dermatitis or pruritic dermatitis, associated with Sarcoptes scabiei, fleas, Malassezia spp.

Mean age of the dogs and the cats was 7.6 and 5 years respectively. The medical records of 53 dogs and cats with aural haematoma treated with Penrose drainage were retrospectively reviewed.
