![]() ![]() Seven days after surgery, the sutures were removed and Happy was closely monitored for any signs of reappearance of the haematoma. This solution contains 2% acetic acid and 2% boric acid, which has antibacterial and antifungal properties. Both of Happy's ears were cleaned with an acetic acid-based ear cleaning solution ( MalAcetic®) every 2 days.Chlorpheniramine at 4mg twice per day, by mouth, for 7 days, to reduce irritation.Itraconazole at 5 mg/kg once per day, by mouth, for 4 weeks, to treat the Malassezia spp overgrowth.Carprofen (NSAID) was given at 4 mg/kg once per day, by mouth, for 5 days.To discourage the subcutaneous tissues from refilling with fluid, several vertical sutures were placed either side of the surgical wound on the medial aspect of the ear using monofilament non-absorbable material.Īfter the surgery, a bandage was applied to the ear an Elizabethan collar was also fitted to minimise the likelihood of further trauma. Fluid and blood clots were removed completely. (An 'S' shaped incision can be made as an alternative). An incision was created down the length of the concave (medial) aspect of the pinna (Figure 4). The patient was anaesthetised and the ear aseptically prepped for surgery. ![]() At this point, a surgical intervention was required. Unfortunately, the haematoma had reappeared the next day. Once the fluid was drained, a bandage was used to apply mild pressure on the pinna, to discourage further bleeding. It is important to maintain sterile conditions by cleaning the skin with antiseptic solution beforehand and wearing clean gloves, in order to prevent introducing infection. Initially, the aural hematoma was managed medically by draining the subcutaneous blood using a large gauge needle and a 20 ml syringe. Inset, right: high power image of the stained Malassezia spp. Inset, left: an illustration to show the shape of a Malassezia yeast. Malassezia pachydermatis are characterised by their appearance under a microscope as little 'snowmen' with a small circle on top of a larger circle (Figure 3).įigure 3 - Malassezia organisms are visible (circle), as well as numerous bacteria on this stained cytological smear of the ear canal. The cytology result showed a significant overgrowth of Malassezia pachydermatis organisms in the affect ear canal, which were suspected to be the cause of the irritation and inflammation. The sample material was transferred to a microscope slide and stained using 'Diff-Quick'. Diagnostic work upĪ swab of Happy's ears was taken for cytology. The vets working on this case suspected that the underlying cause was most likely to be irritation from infection and/or parasites due to the presence of the malodourous material in the external ear canal. Once identified, it is important to address the underlying pathology, as well as the aural haematoma, in order to reduce the likelihood of recurrence. chronic haematoma, ceruminous gland hyperplasia) ![]() Chronic pathological changes to the ear (e.g. ![]()
