Department of Anatomy, University of Reims As Hitier et al. point out, another helpful tool in deciding Champagne-Ardenne on the surgical strategy is the peroperative evaluation by the surgeon of the ossicular chain mobility. The outcome France of this procedure has been reported in 13 of 18 reviewed cases, and a stapes footplate ankyloses is reported in 12 of Vincent Patron, M.D., M.Sc. 13 evaluated cases.
