Head & Neck Flashcards
Aural Hematoma: Cats or dogs or both
Dogs> Cats
Aural Hematoma: Cx
Head shaking; Enlarged and inflammed ear
Aural Hematoma: Common presentation
Dogs shaking their heads; Have an underlying condition
Aural Hematoma: etiology
Inflammation causes skin to separate from cartilage; blood accumulates in cavity; fibrosis
Aural Hematoma: Dx
C/S and apperance
Aural Hematoma: Treatment
Treat underlying condition - atopy, otitis; Sx cx: Serpentine cut of partial thickness and staggered sutures
Aural Hematoma: Prognosis
Mostly resolves
Inflammatory polyp: Cats or dogs or both
Cats > Dogs
Inflammatory polyp: Cx
Head shaking; Otitis externa; Otitis media; Nasal discharge; Snoring (stertor); Reverse sneezing; Sneezing
Inflammatory polyp: Common presentation
Young cats (1.5 yo average); Horner’s Syndrome; Vestibular disease; Chronic otitis media
Inflammatory polyp: Classic lesion
Pedunculated: non-neoplastic mass in ear canal and nasopharynx; must check to see w/ tympanium; Nasopharyngeal polyp: Soft palate
Inflammatory polyp: Dx
Imaging: CT; Endoscope; Histopath
Inflammatory polyp: Treatment
Simple traction/avulsion + NSAIDs; Open SX removal via ventral bullae osteotomy (Cats have a mid-ear septum that you need to break; you don’t fuck around with the external ear)
Inflammatory polyp: Complications
Horner’s Syndrome; Vestibular disease; Deafness; Wound drainage/hemorrhage; Vasoglossal nerve damage; Chronic otitis media
End Stage Otitis Externa: Cats or dogs or both
Dog > Cats
End Stage Otitis Externa: Cx
External ear hyperplastic, mineralized and stenotic; +/- discharge; Animal feels pain upon opening mouth; Check all LNs
End Stage Otitis Externa: Common presentation
Dog with chronic ear infection
End Stage Otitis Externa: Classic lesion
Bulla can change and inflammation can affect the TMJ; Chronic infection could transform into neoplasia
End Stage Otitis Externa: Dx
Allaergy assessment; Neoplasia staging; FNA; Head CT
End Stage Otitis Externa: Treatment
Zepp; Vertical Canal Ablation; TECA-BO (Sx of choice)
End Stage Otitis Externa: Prognosis and complication
Zepp (Ongoing otitis externa; lack of patency); Vertical Canal Ablation (stenosis, infection, dehisce); TECA-BO (recurrent deep infection)
Zepp
Removes small tumor in the horizontal canal
Vertical Canal Ablation
Use to treat disease located exclusively in vertical canal (need imaging)
TECA-BO (Total Ear Canal Ablation and Lateral Bullae Osteotomy)
Surgery of choice; Used for irreversible ear disease or severe compromise of the ear canal; extremely painful so pre, peri and post-op pain management is essential
Sialocele: Cats or dogs or both
Dogs > Cats
Sialocele: Cx
Swelling in the cranioventral cervical region; Acute or chronic onset
Sialocele: Common presentation
Daschunds commonly develop Sialoceles
