self-trauma to the pinna by scratching or head shaking
Otitis Externa is the usual predisposition for an aural hematoma. What is the primary reason in dogs for Otitis Externa?
allergies
Otitis Externa is the usual predisposition for an aural hematoma. What is the primary reason in cats for Otitis Externa?
ear mites
Medical management of an aural hematoma…
is ideally suited for early onset or small hematomas
consists of aspirating the blood and infusing with a steroid
entails placing a drainage system
After incising and drainage of the aural hematoma why is plastic tubing placed on either side of the incision line and suture passed through it?
The plastic tubing allows for even pressure to be placed on either side of the incision site without the suture digging into the tissue.
What would be a result of an untreated aural hematoma?
fluid eventually will be resorbed
fibrosis would occur contraction of the pinna “cauliflower contracture”
Why is bandaging of the ear important in post-operative care of an aural hematoma patient?
It helps to decrease swelling, discharge and trauma
What is the preferred way to prevent recurrence of an aural hematoma?
diagnose and treat the underlying cause for the otitis externa

Chronic otitis externa
Pinna hyperplasic
Congenital anomaly
Which of the following structures surround the area of surgery for a lateral ear canal resection and could be compromised?
facial nerve
Which of the following is / are TRUE when prepping for a lateral ear canal resection?
a four quadrant drapping system is employed
Povidone Iodine may be a choice for surgical prep of a lateral ear canal resection because…
diluted it is not ototoxic
Which instrument is best for incising the cartilage of the lateral ear canal?
Serrated straight mayo scissors
The transverse surgical closure of a resected lateral ear canal removal surgery is…
ventral to the horizontal ear canal opening
Which of the following suture material would be best to suture the skin to the cartilage of a lateral ear canal resection?
Polypropylene
Which of the following is / are a cause for failure of the lateral ear canal resection surgery to be “curative”?
herpes virus infection
Common outcome to untreated entropion is / are…
Corneal ulceration
Corneal hyperpigmentation
Visual defects
The patient undergoing an entropion repair is placed in…
lateral recumbency
Povidone Iodine may be a choice for surgical prep of an entropion surgery because…
diluted it is not traumatic to the eye
Entropion surgery requires…
removal of a section of skin to reverse inward rolling of the eyelid
most patient to be 6 to 12 months of age for adult facial maturity
an ophthalmic surgical pack
The surgical technique for ventral entropion correction is…
Holtz-Celsus technique
Initial incision for a ventral entropion repair is performed with a scalpel blade. Removal of the skin is dissecting with…
tenotomy scissors
Post-surgical site care for entropion surgery includes…
ophthalmic antibiotics
Which of the following is / are TRUE in regards to a prolapsed gland of the nictitans?
The nictitating membrane aids in the removal of dirt and particles from the eye
the gland of the nictitans secretes about 30% of tears produced
removal of the gland of the nictitans can result in KCS (keratoconjunctivitis siccs) “dry eye”.
