Diphtheroid necrotic laryngitis in three calves - diagnostic procedure, therapy and post-operative development.

Diphtheroid necrotic inflammation of the larynx in calves in its advanced stage mostly requires surgical therapy. Diagnostic procedure, surgery and post-operative care were described for three calves (aged 3-8 weeks). The clinical diagnosis was confirmed by laryngoscopy. In all three cases, a laryngotomy with resection of necrotic tissue was performed. After surgery two calves showed complications (tracheal stricture, mucosal hyperplasia). Both were cured in further surgery. In cases of post-operative complications, further surgical intervention can be very promising.
