Original publication title: Retrospective evaluation of ceruminous gland tumors confined to the external ear canal of dogs and cats treated with biopsy and COlaser ablation.
Plain-English summary
A 7-year-old cat was diagnosed with a ceruminous gland tumor in the ear canal after showing signs of discomfort and ear infections. The veterinarian performed a biopsy to confirm the tumor type and then used a COlaser to remove it. This treatment was effective, with only a low chance of the tumor returning. The cat recovered well, and the procedure had minimal complications, making COlaser ablation a good option for similar cases in pets.

Abstract
BACKGROUND: Treatments currently available for ceruminous gland tumors include surgery and radiation therapy, which come with high financial costs and frequent complication and recurrence rates. HYPOTHESIS: To evaluate the treatment, response, complication, and recurrence of ceruminous gland tumors confirmed with biopsy and ablated using COlaser. METHODS: Retrospective review of medical records from Iowa State University and the University of Illinois between January 1, 2016 and December 31, 2021. Electronic medical records were evaluated for a histopathologically confirmed ceruminous gland tumor via video-otoscopic aided biopsy and subsequent COlaser ablation. Signalment, tumor type, size, location within the ear canal, length of time tumor was present before presentation, advanced imaging, and follow-up including recurrence were assessed. RESULTS: Fourteen ceruminous gland adenomas (4 dogs, 10 cats) and 12 ceruminous gland adenocarcinomas (7 dogs, 5 cats) were identified. Bacterial otitis externa was present in 4/26 (15%) animals. Recurrence was identified in 1/14 (7%) ceruminous gland adenomas and 1/12 (8%) ceruminous gland adenocarcinomas. CONCLUSIONS AND CLINICAL IMPORTANCE: Video-otoscopic aided biopsy and COlaser ablation of ceruminous gland tumors in dogs and cats is a viable treatment option with low recurrence and complication rates with COlaser ablation.
