Otic surgery Flashcards
List 5 indications for ear surgery
trauma
aural haematoma
neoplasia
certain cases with chronic otitis externa
chronic otitis media
Describe how to treat aural haematomas
lost of options including drainage and suturing , instillation with glucocorticoids, placement of indwelling drain
BUT need to manage the underlying cause of the ear irritation
List 3 possible complications of aural haematoma
Cosmetic alterations
Recurrence of haematoma
Pinna necrosis
List 2 indications of lateral wall resection of the ear
neoplasia of the lateral wall of the vertical canal
rarely in management of otitis media- allows flushing and drainage of bulla
when will a lateral wall resection of the ear fail
if there is chronic, irreversible, hyperplastic changes to the luminal epithelium
List 5 complications of lateral wall resection of the ear canal
post-op pain
incisional dehiscence
persistent otitis externa
Persistent, unrecognised otitis media
Failure to provide adequate drainage of the horizontal canal
List 2 indications of vertical ear canal ablation
vertical canal only diseased
neoplastic disease and polyps restricted to the vertical ear canal
List 5 possible complications of vertical canal ablation
Postoperative pain/discomfort
Incisional dehiscence
Persistent otitis externa
Persistent, unrecognised otitis media
Stenosis of horizontal canal
List 2 surgical options to manage chronic otitis externa/ media
Total ear canal ablation and lateral bulla osteotomy (TECA BO)
Ventral bulla osteotomy (VBO)
List 4 indications for a total ear canal ablation (bulla osteotomy)
chronic otitis externa associated with irreversible hyperplastic changes in luminal epithelium
Failure of more conservative surgery to alleviate otitis externa or media
Neoplasia of the external ear canal
Otitis media
List 8 possible complications of TECA BO
Postoperative pain/discomfort
Deafness
Incisional dehiscence
Facial nerve paralysis
Vestibular disturbances
Haemorrhage
Horner’s syndrome
Recurrence/abscess formation
List the classic features of Horners syndrome
Anisocoria with ipsilateral miosis
Ptosis of the upper eyelid
Narrowing of the palpebral fissure
Enophthalmos
Protrusion of the third eyelid
List 3 indications of vental bulla osteotomy
In cases with middle ear disease and the following:
Cases in which a TECA is not required
Certain brachycephalic breeds of dog
Often used in the cat
List 8 pontential complications of VBO - ventral bulla osteotomy
Postoperative pain/discomfort
Deafness
Incisional dehiscence
Facial nerve paralysis
Vestibular disturbances
Haemorrhage
Horner’s syndrome
Recurrence/abscess formation
what is a cholesteatoma
Slowly enlarging, cystic lesions within the middle ear cavity
