Questions
• Do you trim the cartilage?
• How do you close the laceration?
• How will you dress it?
Ear Lacerations
• Anatomy
– auricle (pinna) – modified horn shaped structure
composed of elastic cartilage covered by skin –
converges onto the external auditory meatus (canal)
– Cartilage is avascular and needs blood supply from
overlying skin and perichondrium
– earlobe
• with blunt forces ensure no ruptured TM
Ears Lacerations
management
•
Debride non-viable skin and cartilage
•
Ensure enough skin to completely cover cartilage
–
•
can trim up to 5 mm of cartilage while avoiding major
cosmetic defect
“Through and through” lacerations - 3 layer closure
1.
Approximate cartilage edges
•
•
•
4-0, 5-0 absorbable suture
Include both anterior and posterior perichondrium in suture or
sutures will pull through cartilage
Use the folds of pinna as landmarks
2. Repair posterior skin
•
5-0 non-absorbable suture
3. Repair anterior surface
•
•
•
5-0, 6-0 non-absorbable suture
Use landmarks
Ensure edges of free rim are everted to avoid “notching”
•
NB: Some ENT’s advocate suturing all three layers
together
•
All repaired ears should be enclosed in a compression
dressing
•
Consider antibiotics for heavily contaminated wounds
Case 2
• 16 year old wrestler
– Head slammed on floor
during training
– Not wearing protective
headgear
• Diagnosis?
• Management?
Source: NEJM 1996: 335(6)
Cauliflower Ear
subchondral hematoma
• Bridging vessels between perichondrium and cartilage are
torn
• Hematoma stimulates cartilage growth in overlying
perichondrium  “cauliflower”
• Perfect hemostasis to prevent permanent damage
• Refer all but most simple hematomas to plastics or ENT
• Compression dressing
Management
• Small hematoma
– Needle drainage (22G) and close observation
• Large hematoma
– I&D (use landmarks to hide incision)
– Suction or curettage to remove hematoma
– Compression dressing x 4-7 days
– Close ENT follow-up
Cauliflower Ear
CASE 3
• 26 year old male
–
–
–
–
Just returned from diving holiday in the Caribbean
Right ear itchy x 1 week
Now c/o right ear pain and moderate discharge
Normal hearing
• O/E
– VSSA
– Ear canal erythematous and edematous with some cloudy
discharge.
– TM moderately red, but not bulging
– Patient very tender when you press on his tragus
Acute Otitis Externa
• What are the most common pathogens?
– Pseudomonas
– S. aureus
• Treatment
– Cleansing
• Tap water, vinegar
– Topical antibiotics
• Generally aminoglycoside/steroid, fluoroquinolone/steroid
combination
– Systemic antibiotics
• May be necessary in severe cases, particularly if also cellulitis
• Severe cases
– Wicking (cotton, gauze)
– Allows medication to penetrate into the
auditory canal
– Should be left in 2-3 days
• Suppose your patient is an elderly
diabetic. What complication are you
concerned about?
• Malignant otitis externa
– Osteomyelitis of the skull base
– pseudomonas
the nose
Case 4
• 24 year old male
– Drunk
– Was minding his own business when
somebody punched him in the face
– Now moderate epistaxis and crooked nose
Nasal Fracture
diagnosis
• History
– “Have you broken your nose before?”
– “does your nose look normal to you?”
– Breathing difficulty
• Physical examination
–
–
–
–
–
Crepitus, hypermotility, edema, tenderness, deformity
Depressed, laterally angulated, comminuted
if mechanism severe look for other injuries
epistaxis
septal hematoma

To x-ray or not to x-ray ….
• Clayton M, et al. The role of radiography
in the management of nasal fractures. J.
Laryngol Otol. 1986: 100:797-801.
– 54 patients
– Prospective clinical & radiological assessment
& examination under anaesthesia
– X-rays did not change management
• Delacey et al (1977)
– 100 ED patients with nasal fractures
– Compared normal x-rays to those of patients
with clinical fractures
– No diagnostic utility of x-rays because of high
incidence of “bony abnormalities”
• Mayell et al (1973)
– 107 patients with nasal fractures
– Negative or positive x-rays did not change
management or reduction decisions
The bottom line
If the nose looks good
…and breaths good
You don’t need x-rays
Remember, you have a week to fix it
So what are you going to do about it?
Treatment
• Primary goals
– Restore function
– Cosmetic
• Consider early reduction if
– patient presents before onset of soft tissue edema
– or … severe fracture causing airway problems
• After edema, best to wait 3-4 days for reevaluation
• Closed reduction under local anaesthesia
possible up to 10 days (less in kids)
• F/U within a week
– ENT or plastics
– To ensure acceptable cosmetic result once
edema subsided
Closed reduction
• Anaesthesia
– 4% cocaine for intranasal anaesthesia
– Regional blocks with 1% lidocaine with epi
• Supratrochlear nerve
• Infraorbital nerve
• Nasal dorsum
Good job with the fracture …now
you look in the nose and see…
Septal hematoma
Septal hematoma
• Bulge of nasal mucosa
• Same colour as mucosa
• Prone to infection
– Results in abscess and cartilage
necrosis
• I&D with L-shaped incision
• Pack nose to prevent
•
reaccumulation
Close ENT follow-up

Epistaxis: Systemic Factors
• MM
• Hemodialysis
• Nutritional deficiences
• Medications: ASA, NSAIDs, warfarin,
chloramphenicol, carbenicillin,
dipyridamole

Anterior Epistaxis – 90-95%
• Septal wall
• Kiesselbach’s area
– External carotid
• Sphenopalatine artery
– Internal carotid
• Anterior ethmoidal artery
Slide courtesy of Dr. Anita Hui
Posterior Epistaxis – 5-10%
• Lateral wall
• Both internal & external
carotid
• “Woodruff’s plexus”
– Arterial and venous plexus
– Most common site of
posterior epistaxis
Slide courtesy of Dr. Anita Hui
Epistaxis: Management
• ABC’s
– Airway
– Resp distress
– hypotension
• Correct underlying problem
– CBC, coags
•
•
•
•
Pressure
Ice
Morphine, other medications
Cauterization: chemical (Ag
Nitrate), electrical
Slide courtesy of Dr. Anita Hui
• Large clots in right nare with ++ oozing
• You ask patient to blow their nose
• Oozing site visualized
• Now what?
Nasal anaesthesia
• Cocaine 4%
• 2% lidocaine with epinephrine
• 1:1 mixture of 4% lidocaine and 1:1000
epinephrine
• Cautery
– Silver nitrate
– Bilateral cautery contraindicated – septal
perforation
• Anterior nasal packing
– Absorbable packing materials
• Polysporin/vaseline ointment
• Gelfoam, Surgicel
• Addition of hemostatic agents such as Avitene,
Thrombostat, Amicar
Slide courtesy of Dr. Anita Hui
• Do you pack both sides?
– No good evidence
– Some ENT’s say to pack both sides if using
vaseline-gauze pack because it relies on
pressure and is likely to deviate septum
– Both sides not necessary with Merocel as it
functions mostly by providing matrix for clot
formation
• How long do you leave anterior pack in?
– 48-72 hours
Now suppose
• Blood coming from both nares
• Lots going down back of throat
• No anterior source of blood seen
• Diagnosis?
• Management?
• Disposition?
Management of refractory epistaxis
• Greater palatine foramen block
• Laser photocoagulation (Arg, Nd:YAG)
• Angiographic embolization
• Surgical ligation

– Sensitivity 91%
– Specificity 80%
• CT
How are you going to treat it?
Needle Aspiration
vs
Incision & Drainage
• 3 RCTs

aspiration vs incision and drainage. Arch Otolaryngol Head Neck Surg
1987;113:984-6
– Endpoint = return to normal diet
– Initial success
• 95% - Needle
• 100% - I&D
Stringer, et al. A randomized trial for outpatient
management of peritonsillar abscess. Arch
Otolaryngol Head Neck Surg 1988; 114:296
• N=52
• 93% success needle aspiration
• 92% success I&D
• NB: No statistical analysis of P-values
reported
– Numbers analyzed showed insignificant result
Maharaj et al. Management of peritonsillar
abscess. J Laryngol Otol 1991;105:743-5.
• RCT
• Success
– Needle = 87%
– I&D = 90%
• No statistical analysis done
– However numbers analyzed show no
significant difference
Needle Aspiration
• Anesthesia with topical +/- sc
lidocaine
• 18 - 22 gauge needle
– Aspirate area of greatest
fluctuance
– Tonsil itself not aspirated (pus is
in peritonsillar space)
– Aim medially (avoid carotid)
– Look for pus in superior, middle,
and inferior poles
Incision and Drainage
• Consider I&D if
aspiration positive
– Guarded #11 scalpel
– Aim at area of greatest
fluctuance
– Don’t aim laterally!
– Break loculations with
blunt instrument
Disposition
• Admission vs discharge
• Abx
– IV vs oral
– PCN, 2nd 3rd generation cephalosporin, clindamycin
• Referral for tonsillectomy
– If other indications for tonsillectomy
– Following 2 PTA’s
Case 7
• 5 year old girl
– Tonsillectomy 7 days ago for recurrent
tonsillitis
– Benign post-operative course thus far
– Now brisk bleeding from mouth x 30 minutes
– O/E: 120 85/60 pale spitting up blood
Posttonsillectomy hemorrhage
• 4300 cases/year in US
• 1-5% of cases
• When do they occur?
– Primary - <24 hours
• Related to surgical technique, hemostasis
– Secondary - >24 hours
• 5-10 days
• Sloughing of surgical eschar
• Tonsillar blood supply
– 5 arteries
• Ascending pharyngeal
• Ascending palatine
• Anterior tonsillar branch of lingual artery
• Inferior tonsillar branch of facial artery
• Superior tonsillar branch of the descending
palatine artery
• Tonsilloadenoidectomy (TA)

Post-tonsillectomy bleed
management
• The usual ABC’s
• A & B – head up and forward
• C – fluid resuscitation, group & screen
Post-tonsillectomy bleed
management
• Post-tonsillectomy bleed tray
• Remove clot with suction
– allows vessels to contract
• Pack bleeding site with epinephrine soaked pads
• Bipolar cautery if bleeding site visualized
• Call ENT surgeon – to OR if necessary
