Reparative granuloma seen in cases of gold piston implantation after stapes surgery for otosclerosis

Reparative granuloma following stapes surgery

“…However certain studies have estimated the incidence upto 1.3% [4] to 1.8% [5]. We noted incidence of 0.06% (2 out of 3600).…”

“…Also the type of prosthesis used does not appear to change the phenomenon. Tefl on [6], wire-tefl on [7], stainless steel [7] and gold piston [4] implantation are all mentioned along with reparative granuloma. Thus type of prosthesis and graft does not appear to infl uence the formation of reparative granuloma.…”

Passive and active middle ear implants

“…However the compatibility of gold in the middle ear is the subject of controversy: whilst Pusalkar and Steinbach [47] were able to observe in a total of 102 patients only two with an extrusion after 3 years, other research groups reported a considerably higher rate of extrusion of up to 19% [48]. After initially favourable results [49], [50], gold piston implantations in otosclerosis surgery were also seen increasingly critically [51], as material incompatibility with a formation of repair granulomas is assumed [6], [52]. Today, gold plays a subordinate role and has been increasingly replaced by titanium [53].…”

“…They found no evidence of infection. Tange and colleagues (Tange et al 2002) reviewed 475 stapes surgeries where a pure gold prosthesis was used. They found that in their series the incidence of reparative granuloma was 1.5%.…”
