H/L, labyrinthitis, CN VII palsy
TM ANATOMY
• P/E
• TM
• Normal: pars flaccida, malleus, light reflex, moves with insufflation
CLINICAL

anterior light reflex), no movement
OTITIS MEDIA
OTITIS MEDIA - GUIDELINES

middle-ear inflammation and MEE.
2. The presence of MEE that is indicated by any of the
following:

 b. Limited or absent mobility of the tympanic membrane
 c. Air fluid level behind the tympanic membrane
 d. Otorrhea
OTITIS MEDIA
• 3. Signs or symptoms of middle-ear inflammation as indicated
by either

Nasal Anatomy
Etiology
Management of Anterior Bleeds
Management of Posterior Bleeds
QUESTION
• What are the arteries which are involved in anterior
epistaxis (ie. Kiesselbach’s Plexus)?(5)
EPISTAXIS
• Most cases in children although bimodal distribution
• Anterior ~90% of cases in Kiesselbach’s Plexus
• ant. ethmoid, sphenopalatine, greater palatine, superior labial arteries
• Posterior Epistaxis from posterior branch sphenopalatine
artery
NASAL ANATOMY
EPISTAXIS
• Causes
•
•
•
•
•
TRAUMA – self, assault, surgical
Mucosal – URTI, allergies, cold/dry weather
Bleeding diatheses
Etc.
Hypertension – NOT a cause of bleeding but may worsen active
bleeding
EPISTAXIS
• Preparation, proper equipment and an organized step-wise
approach will be the key to success or…
MANAGEMENT - ANTERIOR
•
•
•
•
•
•
Clear clots
Apply pressure for 15-20 min with clips – over septum!!!
With nose parallel to ground use nasal speculum
Use headlight or assistant for light source
Suction as necessary
Check  if continued bleeding…
MANAGEMENT - ANTERIOR
• Apply pledgets soaked in:
• Lidocaine w/ Epi
• Cocaine
• Xylometazoline (Otrivin)

Re-examine  if bleeding persists…
MANAGEMENT - ANTERIOR
• If light or no bleeding but identify source
• Silver Nitrate
• Outside to inside
• Avoid on both sides of septum
• Re-examine  if bleeding persists…
MANAGEMENT - ANTERIOR
• Nasal Packing
• Nasal Packing with Vaseline gauze
• Nasal Tampon/Rhino-Rocket – 8 or 10cm sizes
• May need bilateral packs
*warn patient that Nasal tampon insertion will be painful for about 10 seconds
MANAGEMENT - ANTERIOR
• If success leave packing in for 48hrs, consider antibiotic
prophylaxis
• Prevention: avoid blowing nose, picking, closed mouth
sneezing, apply Polysporin cream
• If STILL bleeding
• Consider posterior bleed
MANAGEMENT - POSTERIOR
• Commercial Balloon Cather – Epistat
• Foley Catheter
• Prophylaxis with Keflex/Clavulin
• ENT consultation
MANAGEMENT
• If all of above fails time to call ENT
• In case of massive, life threatening bleed
•
•
•
•
•
ABC’s
Establish Advanced A/W
Nasal Packing
Fluids/Blood Products – PRBC’s, FFP, Plts, PCC
call ENT/IR/Vascular
SUMMARY
• AOM is common – be aware of treatment
guidelines and rare complications including
mastoiditis
• OE is very painful but quite benign, be aware of
NOE as a complication
• Have an approach to the patient with epistaxis,
consider posterior bleed if unable to achieve
hemostasis with above techniques
