The study was aimed to surgically treat the buffaloes suffering from chronic otorrhoea. It was a prospective clinical study with a compilation of case reports. The study investigated 8 adult buffaloes suffering from chronic otorrhoea associated with accumulation of calcified pus in the horizontal ear canal. These 8 buffaloes were refractory to ear canal flushing and medicinal treatment. Resection of the lateral ear canal was carried out under sedation using inj. xylazine 0.025 mg/Kg or inj. midazolam 0.2 mg/Kg, intravenously and local infiltration anaesthesia (2% lignocaine hydrochloride). Majority of buffaloes recovered uneventfully within 2 weeks; one buffalo took 5 to 6 weeks for complete recovery. The surgical technique was found to be a simple, clinically relevant, and feasible under field settings. This communication recommends surgical resection of the lateral ear canal for the treatment of chronic otorrhoea in buffaloes to remove the calcified pus accumulated in the horizontal canal and to facilitate drainage in clinical cases of otorrhoea refractory to ear canal flushing and / or conservative medicinal treatment.
