Study highlights recurrence risk in cats with ceruminoliths

Cats treated for ceruminoliths often did well initially, but recurrence and tympanic damage were common in a new retrospective study from France that reviewed 31 cases seen between 2011 and 2024. The Veterinary Dermatology paper found that 26 cats underwent otoendoscopy-guided lavage under general anesthesia plus medical therapy, while five were managed medically alone. Ceruminolytic cleaners and short courses of systemic glucocorticoids were commonly used. Tympanic lesions were frequent, including perforation in 10 cats and thickening or discoloration in five. At the first follow-up, 55% of cats were free of ceruminoliths, and 65% remained recurrence-free at final follow-up. (pubmed.ncbi.nlm.nih.gov)

Why it matters: For veterinary professionals, the study adds case-series evidence around a condition that appears to be underrecognized in cats, despite longstanding clinical discussion that ceruminoliths can act as a foreign body, perpetuate inflammation, and complicate chronic otitis. The findings reinforce the value of thorough otoscopic or video-otoscopic evaluation, attention to tympanic membrane status, and follow-up plans that go beyond immediate debris removal, especially because some tympanic changes persisted and recurrence was not rare.

What to watch: Whether future studies better define the underlying drivers of recurrence, including chronic otitis, prior ear mite disease, medication debris, and other predisposing ear canal changes. (pubmed.ncbi.nlm.nih.gov)
