ABSTRACT Tuberculous otitis media (TOM) is rare inENT department, and is frequently misdiagnosed as otitis media. Thus early systemic treatment is very important forTOM. We reported a case report withTOM to highlight development of the disease and difficulties in clinical treatment in late stage ofTOM. Implantation of ossified and eroded cochlea poses many unique challenges to both the surgeon and programming team. With thorough preparation and complete knowledge about characters of specific issues, implantation would be performed successfully, and patients with ossified cochlear could benefit from cochlear implantation.
