Antibiotics to Consider for Rx of Sinusitis Complications ƒ  Ceftriaxone 1 gm IV q 12h ƒ  Cefotaxime 2 gm IV q 4h ƒ  Ceftizoxime 4 gm IV q 8h + metronidazole 30 mg/Kg/d ƒ  Ampicillin / sulbactam 3 gm IV q 6h ƒ  Vancomycin 500 mg q 6h + aztreonam 1 gm q 8h or chloramphenicol ( for PCN - allergic patients) 18
  19. 19. Acute Mastoiditis ƒ  Uncommon now due to antibiotic use for otitis media ƒ  Most common causative bug is Strep pneumoniae ƒ  Rx is IV antibiotics, myringotomy, & drainage ƒ  Mastoidectomy for resistant or complicated cases ƒ  Related serious problem is Necrotizing External Otitis (or “Malignant External Otitis”) ƒ Usually caused by Pseudomonas ƒ Requires IV antibiotics for 4 weeks and radical surgical debridement 19
  20. 20. Source Undetermined Source Undetermined Child with acute mastoiditis from concurrent otitis media 20
  21. 21. Acute Chondritis ƒ  Can be complication of ear piercing ƒ  Most commonly caused by Pseudomonas but can be due to Strep or Staph ƒ  Requires IV antibiotics ƒ  Also needs incision, drainage, and pressure dressing if abscess present 21
  22. 22. Patients with acute chondritis Source undetermined 22
  23. 23. Mucormycosis ƒ  An aggressive opportunistic fungal infection usually with Mucor or Rhizopus ƒ  Occurs in immunocompromised and poorly controlled diabetic patients ƒ  Mortality 30 to 70 % ƒ  Requires IV and topical amphotericin B and aggressive surgical debridement 23
  24. 24. Source Undetermined Source Undetermined 24
  25. 25. Source undetermined 25

  27. 27. Peritonsillar Abscess ƒ  Complication of acute tonsillitis ƒ  Unilateral peritonsillar and soft palate swelling with uvular deviation ƒ  Most commonly caused by Strep species but can be polymicrobial ƒ  Usually have trismus, drooling, muffled “hot potato” voice ƒ  May need CT to r/o parapharyngeal abscess ƒ  Requires antibiotics, needle aspiration, and later interval tonsillectomy 27
  28. 28. Appearance of peritonsillar abscess Image sources undetermined 28

  30. 30. Retropharyngeal and Parapharyngeal Abscesses ƒ  Sx are neck swelling, fever, dysphagia, muffled voice, neck hyperextension ƒ  Due to suppuration of retro- or parapharyngeal lymph nodes, or direct trauma ƒ  Requires CT scan to delineate extent of abscess, IV antibiotics, surgical drainage, and sometimes airway protection with intubation 30
  31. 31. Plain film of retropharyngeal abscess Source undetermined 31
  32. 32. Another plain film of retropharyngeal abscess Source undetermined 32
  33. 33. Source undetermined Parapharyngeal abscess on CT 33
  34. 34. Parapharyngeal abscess (note endotracheal tube in place) 34 Source undetermined
  35. 35. Ludwig’s Angina ƒ The most common neck space infection ƒ Is a rapidly swelling cellulitis (+/- abscess) of the sublingual and submaxillary spaces, usually arising from molar and premolar tooth root infections ; usually polymicrobial infection including anerobes ƒ Most patients are toxic, severely ill, dehydrated ƒ Risk of airway obstruction due to upward tongue swelling ƒ Need CT to delineate any abscess present ƒ Rx: tracheostomy, IV antibiotics, incision and drainage of the neck, excision of source teeth 35
  36. 36. Kulkarni et. al., Wikimedia Commons Patient with Ludwig’s angina (note typical brawny swelling of the submandibular area) 36
  37. 37. Vincent’s Angina ƒ An acute necrotizing infection of the pharynx and/or tonsils caused by a combination of fusiform bacilli and spirochetes (the same organisms that cause acute gingivostomatitis or “trench mouth” ƒ May have fever, lymphadenopathy, and metallic taste ƒ Need CT to look for gas and if any associated abscess in the soft tissues ƒ Rx : IV penicillin and/or clindamycin, surgical debridement of necrotic tissue 37
  38. 38. Source undetermined Acute necrotizing ulcerative gingivitis 38
  39. 39. Acute Epiglottitis ƒ  Due to HiB vaccine, is now rare (I’ve never seen a case in my entire career) ƒ  Most cases now are in men age 40 to 60 ƒ  Usually caused by Hemophilus sp. and Strep pneumoniae ƒ  Adult mortality reportedly 7 % ƒ  Most patients febrile, toxic, drooling, muffled voice ƒ  Need CT to r/o parapharyngeal abscess ƒ  Rx : IV ceftriaxone, +/- airway control 39

  42. 42. Source undetermined CT scan of same patient as on prior slide ; note column of air around the epiglottis (E) ; the right side of the epiglottis is more swollen than the left ; hypoattenuation at “A” is suggestive of 42 early abscess
  43. 43. E.N.T. Emergencies Related to Sepsis : Lecture Summary ƒ Maintain low threshold for workup with facial CT, particularly in immunocompromised patients ƒ Start IV antibiotics early ƒ Don’t forget routine resuscitative measures (such as IV fluid bolus) and blood cultures in febrile or toxic patients ƒ Early consultation with your friendly otolaryngologist ƒ May require additional consults to neurosurgery or ophthalmology ƒ Use consultant to decide if pre-operative needle aspirates for culture 43
