Investigation on ear diseases in dogs and application of lateral ear canal resection technique for external otitis treatment

Abstract

The survey was conducted on 5.166 dogs at three veterinary clinics in Ho Chi Minh City from July to October 2018 and evaluated the efficiency of “Lateral Ear Canal Resection (LECR)” technique on 12 experimental dogs and 2 real cases (one case presented narrow ear canal and one case suffered with otitis due to the excessive and deep-in-canal hair growth). The study aimed to provide background information about ear diseases in dogs and apply LECR technique in clinical ear disease’s treatment. The studied result indicated that there were 168 dogs presented ear diseases, accounting for 3.25% in the total of surveyed dogs. The prevalence of ear diseases in the exotic dog breeds was higher than that of the indigenous dogs (p < 0.05). The incidence of this disease increased gradually by the dog age group, reaching the highest infection rate in the dog group at over 24 months old (p < 0.01). The ear shape was also affected to the ear disease infection. The dogs with flapped ears were considerably infected with the ear diseases with higher infection rate in comparison to the erected ones (p < 0.05).
