[Ankylosis of the stapes by post-inflammatory osteogenesis (or syndrome of Coyle Shea Jr). Report of two cases (author's transl)].

Ankylosis of the stapes by post-inflammatory osteogenesis (syndrome of Coyle Shea Jr) is a pathologic entity still not well known, often confounded with otosclerosis. If surgical treatment is the same as for otosclerosis (stopedectomy, platinectomy, veinous graft and piston), the prognosis is not the same and a great carefulness is necessary, as well in operatory indications as in operatory procedure itself.
