Purulent discharge from the right ear was also observed; diagnostic imaging was consistent with otitis media and otitis externa. <jats:italic>Yokenella regensburgei<\/jats:italic> was repeatedly cultured from the site. Clinical signs resolved with topical antibiotic therapy; however, recrudesced following cessation of antibiotics. A total ear canal ablation and lateral bulla osteotomy was performed, followed by an extended period of systemic antibiotic therapy. Mild facial nerve paresis was observed for 4\u2009weeks postoperatively and resolved spontaneously. The koala remained clinically healthy for the 6\u2009months it was monitored following release.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Total ear canal ablation combined with lateral bulla osteotomy appears to be an appropriate surgical intervention for otitis media combined with otitis externa refractory to medical management in the koala. Transient postoperative facial nerve paresis is a possible complication, as documented in other species. To the authors' knowledge this is the first case of <jats:italic>Yokenella regensburgei<\/jats:italic> infection outside of humans and American alligators (<jats:italic>Alligator mississippiensis<\/jats:italic>);
