Earlier this week we shared a post about our approach to ear cytology. Today, meet the patient behind that slide: little Milo.
Milo was referred to us for chronic right sided otitis. On presentation he was extremely painful – too sore to allow even a basic otoscopic exam. He was shaking his head, yelping on touch, and clearly distressed. Given the severity, he was admitted for a CBCT scan and video otoscopy.
The imaging and otoscopy findings explained everything. The ear canal was swollen and ulcerated, with active discharge and a slimy, adherent exudate coating the walls. The tympanic membrane was not visible initially due to inflammation and debris, once clean we could see that it was intact. Cytology confirmed Malassezia within a biofilm – a key contributor to recurrent, treatment resistant flare ups.
A few interesting points from Milo’s case:
• Biofilm involvement likely contributed to his rapid relapse as biofilms can protect organisms from topical therapy.
• His CBCT showed no middle ear involvement, reinforcing the value of advanced imaging in differentiating external canal disease from otitis media.
• The degree of ulceration seen on video otoscopy highlights how easily chronic otitis can progress when flare ups aren’t fully resolved.
• Pain on presentation was a useful clinical indicator of deeper pathology – a reminder that behavioural signs often correlate strongly with canal pathology.
Milo has now started a targeted treatment plan based on his cytology and endoscopic findings. We’ll be reviewing him in two weeks to monitor healing, reassess comfort, and ensure we’re preventing further chronic change.
