McMaster University POS 2009 ENT EMERGENCIES McMaster University POS 2009
Overview ENT Ears = Otologic Nose = Rhinologic Throat = Oral/Pharyngeal/Laryngeal Infections Facial injuries Airway Obstruction
Otologic Anatomy Auricle Ear canal Tympanic membrane Middle ear & mastoid Inner Ear
Trauma of the Auricle Subperichondrial Hematoma Shear force trauma Perichondrium lifted & bleeds Drain before cartilaginous necrosis Leave drain, Abx, bolster dressing, monitor/24hrs “Cauliflower” ear asymmetric cartilage formation the presence of a hematoma has been found to stimulate new and often asymmetric cartilage to form
Aspiration of Auricular Hematoma
Middle Ear Mastoiditis Venous connection with brain, need aggressive treatment (can lead to brain abscess or meningitis)
Epistaxis 90% (Little’s Area) Kiesselbach’s plexus - usually children, young adults 10% of all epistaxis - usually in the elderly
Nasal Septum
Lateral Wall
Epistaxis Management Pain meds, lower BP, calm patient Prepare ! (gown, mask, suction, speculum, meds and packing ready) Evacuate clots Topical vasoconstrictor and anesthetic Identify source
Epistaxis Management Anterior Sites - Pressure +/- cautery and/or tamponade - all packs require antibiotic prophylaxis
Epistaxis Posterior Packing Need analgesia and sedation require admission and 02 saturation monitoring
Epistaxis Complications severe bleeding hypoxia, hypercarbia sinusitis, otitis media necrosis of the columella or nasal ala
Parotitis Usually viral -paramyxovirus Bacterial - elderly, immunosuppressed associated with dehydration Management cover - Staph, anaerobes Hydrate Sialogogues Warm compresses Pain control
Peritonsillar Abscess Cellulitis of the space behind tonsillar capsule extending onto soft palate leading to abscess. The pus is located between the tonsillar bed and the capsule anterosuperior to the anterior pillar. Complication from acute/chronic tonsillitis vs. Weber’s gland Unilateral Most common 10-30 years old
Left Peritonsillar Abscess
Left Peritonsillar Abcess
Left Peritonsillar Abscess
CT-SCAN peritonsillar abscess
Peritonsillar Abcess Inferior - medial displacement of tonsil and uvula dysphagia, ear pain, muffled voice, fever, trismus Group A strep, Strep pyogenes, Staph aureus, H. influenzae, Anaerobes Treatment - Antibiotics (clinda), I&D, +/-steroids
Epiglottitis Clinical Picture Acute inflammation causing swelling of the SupraGlottic structures of the larynx Older children & 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 Prepare for emergent airway, best achieved in a controlled setting Unasyn, +/- steroids
Soft tissue X-ray of neck Anterior-posterior view is normal Lateral view: ***THUMB PRINT*** swelling epiglottis/ary epiglottic folds fullness of the valleculae ballooned hypopharyx assess the retropharyngeal space
Epiglottitis
Acute epiglottitis: swan neck
Management In Children: Brought in the operating room Be ready to Intubate Have a rigid Bronchoscope ready Have the Tracheostomy tray opened ***All need to be intubated to secure the airway due to the smaller airway in the child.***
Management In Adult: All need to be admitted ICU or Step-down Unit Intubation only if compromise airway Continuous O2 sat monitoring Daily examination of their larynx
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 --****Normal prevertebral soft tissue thickness at C2 is 7 mm. At C6 the thickness is 14 mm for children and 22 mm for adults. -*** soft tissue >50% of width of cervical vertebral body must be investigated -****Normal prevertebral soft tissue thickness at C2 is 7 mm. At C6 the thickness is 14 mm for children and 22 mm for adults.
Deep Neck Space Infection
Ludwig’s Angina Rapid bilaterally spreading cellulitis/inflammation with possible abscess formation of superior compartment of the suprahyoid space: Submandibular, sublingual, submental spaces usually in elderly debilitated patients and precipitated by dental procedures massive swelling with impending airway obstruction
Ludwig Angina Infectious Spread
Ludwig’s Angina Etiology: typically from an odontogenic infection mandibular 2nd or 3rd molar streptococcus, oral anaerobes
Clinical presentation Very tender swelling under mandible + floor mouth Usually little or no fluctuance Severe trismus, drooling of saliva Gross swelling, elevation, displacement of tongue Tachypnea and dyspnea may happen Danger of upper airway obstruction + death
Ludwig angina: swelling
Ludwig angina: trismus
Management ABC’s Awake intubation vs tracheostomy if needed Admit ICU or stepdown unless the airway is totally safe (02 sat monitoring) Drain the abscess I.V. ATB: penicillin, clindamycin, flagyl
Angioedema Ocassionally life threatening Acquired Hereditary -IgE mediated: vasodilation and increased vascular permeability (ie. insect bites, food, etc) -not IgE mediated (ie. ace inhibitors) Hereditary Tx: O2, anti-histamine, steroids, epinephrine Consider intubation/trach
Airway Obstruction All the previously mentioned airway issues can eventually obstruct the patient: Note: Aphonia - complete upper airway Stridor - incomplete upper airway Wheezing - incomplete lower airway Loss of breath sounds- complete lower airway
Airway Management A good rule of thumb about a tracheotomy is if you think about it, you probably should do it. If you need a surgical airway then a cricothyrotomy is the way to go
Complications of acute sinusitis Orbital: preseptal:periorbital cellulitis postseptal: orbital cellulitis subperiosteal abscess orbital abscess Intracranial: meningitis brain abscess cavernous sinus thrombosis Osteomyelitis frontal bone: Pott’s Puffy tumor
Periorbital cellulitis
Orbital cellulitis
Subperiostal orbital abscess
Cavernous sinus thrombosis Absence of valves in the orbital veins allows the blood to flow to the cavernous sinus Rapidly progressive chemosis, ophthalmoplegia Severe retinal engorgement High fever Prostation May progress to vision loss, meningitis, death
Intracranial complications Headache Fever N/V Focal neurological deficits Lethargy Nuchal rigidity Deterioration of level consciousness
Management of Complications of Acute Sinusitis ENT, opht, ID, & neurosx consult CT , MRI I.V. ATB usually prolonged course Drainage of any abscess Orbital decompression if visual acuity decreased Heparinization (Cavernous Sinus Thrombosis)
Questions and Answers
Question? You are seeing a 50 yr old male in the ER for query epiglottitis? During your physical exam the patient stops making any airway sounds, turns blue, grasping at neck & collapses in bed. How do you manage this patient? A) immediately place a chest tube b/c patient most likely has a tension pnemothorax B) immediately place an oxygen mask on patient at fi02 100% C) immediately call for surgeon on call to come place a tracheostomy tube D) immediately perform a cricothyrotomy E) immediately call for a CXR and place a central line

Question? Regarding tracheostomies, the following facts are true except: tracheostomies are commonly indicated for long term ventilation or airway protection swallowing problems are fairly common in patients with tracheostomies an appropriately placed tracheostomy with its cuff inflated virtually eliminates the risk of aspiration tracheostomies should be placed at the level of the second or third cartilaginous ring a tracheo-innominate fistula may occur with tracheostomies placed too low in the trachea
Question? What is the most common cause of death in patients with tracheostomies. Increased aspiration Tube falling out Bleeding Tube becoming obstructed Infection

Question? To avoid the complications of tracheostomy: Which of the following are True? a tracheostomy tube of appropriate size, length and curvature must be used two tracheal rings must be removed judicious suctioning to avoid aspiration of blood during the procedure the skin must be closed tightly around the tracheostomy tube

Question? In a patient requiring a cuffed tracheostomy tube for prolonged closed ventilation, tracheal injury can be best prevented by? Frequent cuff deflation. Use of a non-reactive cuff. Use of an alternating double cuff tube. Use of a wide cuff. Use of a minimal cuff volume to effect adequate seal.
