Summary
Para-aural abscessation in dogs can indicate ear canal separation, often linked to trauma. Surgical intervention, including total ear canal ablation, successfully treated these cases.
Area of Science:
- Veterinary Surgery
- Canine Otology
Background:
- Para-aural abscessation in dogs presents a diagnostic challenge.
- Trauma is a potential cause of external ear canal pathology.
Observation:
- Preoperative suspicion of ear canal separation was based on trauma history, physical exam findings, and radiography.
- Physical examination revealed minimally inflamed ear canals with abrupt endings.
- Radiographic evidence suggested discontinuity of the ear canals and concurrent otitis media.
Findings:
- Surgical exploration confirmed disruptions of the external ear canals in all three dogs.
- All dogs were diagnosed with concurrent otitis media via radiography.
- Surgical treatment involved total ear canal ablation and lateral bulla osteotomy.
Implications:
- Total ear canal ablation and lateral bulla osteotomy are effective treatments for para-aural abscessation secondary to ear canal disruption.
- Early diagnosis and surgical intervention are crucial for successful outcomes in complex ear canal diseases.
- This case series highlights the importance of considering ear canal trauma in dogs presenting with para-aural abscesses.
