(BMJ)—A 3-year-old girl with leukocyte adhesion deficiency type 1 presented with pain and drainage in her R ear. Exam: tender erythema in R postauricular region; ear canal obstructed by granulation tissue. Pseudomonas aeruginosa identified from ear swabs and blood cultures. Despite tx with IV ceftazidime and vancomycin + daily topical ofloxacin, R facial paralysis developed 5 days after admission. What’s the dx?
Sarcoidosis
Squamous cell carcinoma of ear canal
Malignant otitis externa
Ramsay Hunt syndrome
Cerebellopontine angle tumor
You are correct. CT scan of the temporal bone showed erosion in the mastoid tegmen, confirming dx of malignant otitis externa (MOE). MOE occasionally occurs in children w/ compromised host defenses. Unrelenting otalgia, markedly elevated acute-phase reactants, evidence of bone destruction on CT, and increased uptake in gallium-67 (on scintigraphy) should alert the clinician to MOE. Facial paralysis develops earlier and more frequently in pediatric cases. After 8wk of parenteral amikacin and meropenem, simple mastoidectomy at day 10, daily cleansing, and adjuvant hyperbaric oxygen at days 21-46, the pt’s sx improved, including partial recovery of facial nerve function 8wk after surgery.
