B. Quinn, MD February 25, 1998INTRODUCTION: INTRODUCTION Life-threatening infections - rare Influence of antibiotics Lack of systemic signs and Sx ImmunosupressionANATOMIC CONSIDERATIONS: ANATOMIC CONSIDERATIONS Teeth, tonsils Polymicrobial infections 10:1 anaerobes Pathways of spread fascial planes intracranial periorbitalDEEP NECK SPACE INFECTIONS: DEEP NECK SPACE INFECTIONS Usually odontogenic young, healthy, delayed Tx Cervical Fascial Layers Superficial fascia Deep fascia superficial (investing) middle(visceral) deep (prevertebral and alar layers)SUBMANDIBULAR SPACE: SUBMANDIBULAR SPACE 1836 - Wilhelm Von Ludwig implies bilateral involvement boundaries Hyoid to FOM Ant/lat - mandible Mylohyoid “sling” bucopharyngeal gapLUDWIG’S ANGINA: LUDWIG’S ANGINA dysphagia, drooling, muffled voice “woody” induration, no fluctuance Treatment airway control IV ABX Surgical drainageLATERAL PHARYNGEAL SPACE: LATERAL PHARYNGEAL SPACE Inverted cone - hyoid to base of skull Pre-styloid compartment fat, lymph nodes, muscle Post-styloid carotid, IJ, CN IX - XII pain, fever, neck swelling, ?trismusLATERAL PHARYNGEAL SPACE: LATERAL PHARYNGEAL SPACE Ominous signs Horners, bleeding, CN palsies, mediastinitis Treatment Surgical drainage IV ABX jugular vein thrombosis RETROPHARYNGEAL SPACE: RETROPHARYNGEAL SPACE Retropharyngeal space between alar layer and sup. constrictors extends to sup mediastinum Danger space between alar and prevertebral layers diaphragm prevertebral space down to coccyxMASTICATOR SPACE: MASTICATOR SPACE Pterygoids, masseter, temporalis m. Comm w/ temporal space superiorly Trismus! CT can direct surgical approachPERITONSILLAR ABSCESS: PERITONSILLAR ABSCESS Areolar tissue bound by sup. constrictors Rarely life-threatening but can spread Serial aspiration vs I and DNECROTIZING FASCIITIS: NECROTIZING FASCIITIS Synergistic, polymicrobial infection Sup layer of deep fascia Determining necrosis is Key gas, crepitance, failure to respond to ABX Treatment IV ABX Radical surgical debridementACUTE EPIGLOTTITIS: ACUTE EPIGLOTTITIS Now rare in children “Hot potato” voice, drooling, fever No FILMS - go to OR! no fiberoptic exam bronch, trach equipment ready change to nasotracheal tube MUCORMYCOSIS: MUCORMYCOSIS Progressive, invasive fungal infection Severe DM or immunocompromised Black necrotic lesions of nose or palate Radical surgical debridement to bleeding Broad, nonseptate hyphae, right angles AmphoterribleCOMPLICATIONS OF SINUSITIS: COMPLICATIONS OF SINUSITIS Parameningeal, periorbital location Frontoethmoid sinuses frontal lobe abscess, meningitis, subdural empyema Sphenoid sinuses Sup orbital fissure, cavernous sinus Sx of increased intracranial pressureOTOLOGIC COMPLICATIONS: OTOLOGIC COMPLICATIONS Involve middle or posterior fossa Epidural abscess>meningitis>brain abscess Warning signs early - malodorous discharge, fever, HA late - facial paralysis., vertigo Multiple complications are common Malignant otitis externa You do not have the permission to view this presentation.
