Overview
• Otologic Disorders
• Nasal Disorders
• Facial, Oral and Pharyngeal Infections
• Airway Obstruction
Otologic DisordersAnatomy
• Auricle
• Ear canal
• Tympanic membrane
• Middle ear and mastoid disorders
• Inner Ear
Traumatic Disorders of the Auricle• Hematoma
- cartilaginous necrosis
- drain, antibiotics, bulky ear dressing close follow up
• Lacerations - single layer closure, pick up perichondrium, bulky ear dressing
Use posterior auricular block for anesthesia
Aspiration of Auricular Hematoma
Auricle• Chondritis - Cellulitis ?- infectious, difficult to treat
because poor blood supply, cover S. Aureus and pseudomonas
- extra care in diabetics
- inflammatory causes related to seronegative arthritis at times indistinguishable from infection usually the ear lobe is spared
Otitis Externa• Infection and inflammation
caused by bacteria (pseudomonas, staph), and fungi
- treat with antibiotic-steroid drops
- use wick for tight canals
- diabetics can get malignant otitis externa (defined by the presence of granulation tissue)
Foreign Bodies in Ear Canal
• Usually put in by patient, some bugs fly in
• kill bugs with mineral oil, or lidocaine
• remove with forceps, suction or tissue adhesive
Tympanic Membrane Perforation• Hard to see – Hx of drainage• Usually from middle ear pressure
secondary to fluid or barotrauma• Sometimes from external trauma• most heal uneventfully but all need
otology follow-up • perfs with vertigo and facial nerve
involvement need immediate referral• treat with antibiotics• drops controversial but indicated for
purulent discharge (avoid gentamycin drops)
Middle Ear• Serous Otitis Media - Eustachian
tube dysfunction - treat with decongestants, decompressive maneuvers
• Otitis Media - infection of middle ear effusion - viral and bacteria
• Mastoiditis - Venous connection with brain, need aggressive treatment (can lead to brain abcess or meningitis)
Inner Ear
• peripheral vertigo (vestibulopathy)
BPV, labyrhinthitis
• - acute onset, no central signs, usually young, horizontal nystagmus
• Meniere’s - vertigo, sensorineural hearing loss, tinnitus
• Treatment
- valium, fluids, rest, manipulation for BPV
The Nose
• Vascular Supply
- Anterior - branches of internal carotid
- Posterior - distal branches of external carotid
EpistaxisAnterior
• 90% (Little’s Area) Kisselbach’s plexus - usually children, young adults
Etiologies• Trauma, epistaxis digitorum• Winter Syndrome, Allergies• Irritants - cocaine, sprays• Pregnancy
EpistaxisPosterior
• 10% of all epistaxis - usually in the elderly
• Etiologies
• Coagulopathy
• Atherosclerosis
• Neoplasm
• Hypertension (debatable)
EpistaxisManagement
• Pain meds, lower BP, calm patient
• Prepare ! (gown, mask, suction, speculum, meds and packing ready)
• Evacuate clots
• Topical vasoconstrictor and anesthetic
• Identify source
EpistaxisManagement
• Anterior Sites- Pressure +/- cautery
and/or tamponade
- all packs require antibiotic prophylaxis
EpistaxisPosterior Packing
• Need analgesia and sedation
• require admission and 02 saturation monitoring
EpistaxisComplications
• severe bleeding
• hypoxia, hypercarbia
• sinusitis, otitis media
• necrosis of the columella or nasal ala
7th Nerve Palsy• Most cases are idiopathic
- link to HSV
- no proof steroids or antivirals are effective, but many advocate
• Consider Lyme’s Disease in edemic areas
• Surgical decompression indicated in the rare patient not improving by 2 weeks and ENOG out > 90%
Facial InfectionsSinusitis
• Signs and symptoms- H/A, facial pain in sinus
distribution- purulent yellow-green
rhinorrhea- fever- CT more sensitive than plain
films• Causative Organisms- gram positives and H. flu
(acute)- anaerobes, gram neg (chronic)
Facial InfectionsSinusitis
• Treatmentacute - amoxil, septrachronic - amoxil-clavulinic acid,
clindamycin, quinolonesdecongestants, analgesia, heat
• Complicationsethmoid sinusitis - orbital cellulits and
abcessfrontal sinusitis - may erode bone
(Potts Puffy Tumor, Brain Abcess)
Facial Cellulitis
• Most common strept and staph,
• Rarely H.Flu• Can progress rapidly
Parotiditis• Usually viral
-paramyxovirus• Bacterial
- elderly, immunosuppressed
- associated with dehydration
- cover - Staph, anaerobes
Pharyngitis
• Irritants
-reflux, trauma, gases
• Viruses
- EBV, adenovirus
• Bacterial
-GABHS, mycoplasma, gonorrhea, diptheria
Peritonsillar Abcess
• Complication of suppurative tonsillitis
• Inferior - medial displacement of tonsil and uvula
• dysphagia, ear pain, muffled voice, fever, trismus
• Treatment
- Antibiotics, I&D, +/-steroids
EpiglottitisClinical Picture
• Older children and adults• decrease incidence in children
secondary to HIB vaccine• Onset rapid, patients look toxic• prefer to sit, muffled voice,
dysphagia, drooling, restlessness
Epiglottitis
• Avoid agitation
• Direct visualization if patient allows
• soft tissue of neck
- thumb print, valecula sign
• Prepare for emergent airway, best achieved in a controlled setting
• Unasyn, +/- steroids
EpiglottitisEpiglottitis
Retropharyngeal Abcess• Anterior to prevertebral space
and posterior to pharynx• Usually in children under 4
(lymphoid tissue in space)• pain, dysphagia, dyspnea, fever• swelling of retropharyngeal
space on lateral x-ray• Complications - mediastinitis
Masticator - Parapharyngeal Space Infection
• Infection of the lower molars invade masticator space
• Swelling, pain fever, TRISMUS
• Treatment
IV antibiotics (PCN or Clindamycin)
ENT admission
ANUGAcute Necrotizing Ulcerative Gingivitis
• Bacterial infection causing an acute necrotizing, destructive disease of periodontium
• Treatment
- oral rinses
- antibiotics (PCN, clindamycin, tetracycline)
Ludwigs Angina• Rapidly progressive cellulitis of the
floor of the mouth• usually in elderly debilitated
patients and precipitated by dental procedures
• massive swelling with impending airway obstruction
• Treatment
ICU, antibiotics, airway management
Angioedema• Ocassionally life
threatening• Heriditary and related
to ACE inhibitors• Antihistamines,
steroids and doxepin
Airway Obstruction
• Aphonia - complete upper airway
• Stridor - incomplete upper airway
• Wheezing - incomplete lower airway
• Loss of breath sounds- complete lower airway
