UNILATERAL CONGENITAL-MALFORMATION OF THE MEATUS ACUSTICUS EXTERNUS IN A DOG

A 4 month old male Rottweiler was diagnosed with an unilateral atresia of the external meatus. No other abnormalities were seen. The accumul ation of cellular and sebaceous debris caused an inflammation in the a tretic ear canal. The tympanic membrane was intact and there was no in volvement of the middle ear or the bulla. The first surgery to reconst ruct the external meatus failed because the anastomosis stenosed. In a second procedure the anular cartilage was sutured to the skin. One ye ar after the last surgical treatment the dog is doing well.
