Deep Ear Cleaning in Companion Animals

Deep ear cleaning is a critical in-clinic procedure for pets suffering from chronic otitis externa, excessive cerumen buildup, or recurrent ear infections. Unlike routine ear cleaning performed by pet owners at home, professional deep ear cleaning allows veterinarians to thoroughly remove hardened wax, debris, and biofilm, improving treatment efficacy and preventing chronic complications.

When is Deep Ear Cleaning Necessary? 

  • Severe cerumen impaction – When hardened ear wax obstructs the ear canal, leading to inflammation and secondary infections. 
  • Otitis externa with excessive debris – Accumulation of infectious material, bacteria, and yeast, reducing medication penetration. 
  • Chronic or recurrent infections – When previous treatments fail due to biofilm formation or persistent pathogens. 
  • Preparation for otitis treatment – Removing debris improves the effectiveness of topical antibiotics and antifungals. 

  • Aural hematomas or pain from trapped debris – Reducing irritation and inflammation in dogs prone to ear disease. 

Step-by-Step Deep Ear Cleaning Procedure 

  1. Patient Assessment & Cytology – Examine the ear canal with an otoscope and perform cytology to identify the presence of bacteria, yeast, mites, or inflammatory cells. 
  2. Application of Ceruminolytic Agent – Use a ceruminolytic ear cleaner like to soften hardened wax and debris for easier removal. 
  3. Gentle Massage & Wax Dissolution – Massage the ear canal base to help break down cerumen and impacted material. 
  4. Flushing & Suctioning – Use sterile saline or a veterinary ear irrigation system to flush out softened debris, followed by suctioning for deeper cleaning.
  5. Final Examination & Medication Application – After drying the ear canal, apply topicals and other treatments if applicable.
