Revision ossiculoplasty decision

After eradication of cholesteatoma, a dry ear has an intact mobile tympanic graft, absent malleus and stapes superstructure, a mobile stapes footplate, an aerated middle ear and a 35 dB conductive gap. Which reconstruction is anatomically appropriate?

CHOOSE ONE ANSWER

Best of five

  1. A. A partial ossicular replacement prosthesis seated on the footplate
  2. B. Malleovestibulopexy with a piston through the footplate
  3. C. Revision tympanoplasty without ossicular reconstruction
  4. D. Bone-conduction implantation without discussing ossiculoplasty
  5. E. A total ossicular replacement prosthesis from tympanic membrane graft to the mobile stapes footplate
ANSWER AND REASONING

E. A total ossicular replacement prosthesis from tympanic membrane graft to the mobile stapes footplate

With no stapes superstructure and a mobile footplate, a total prosthesis couples the reconstructed drum to the footplate; stability, cartilage protection and ventilation determine outcome.

Why every option is right or wrong

A. A partial ossicular replacement prosthesis seated on the footplate: A PORP requires an intact stapes superstructure; seating it directly on the footplate is mechanically inappropriate.

B. Malleovestibulopexy with a piston through the footplate: Opening a mobile footplate introduces inner-ear risk and is not indicated for post-cholesteatoma ossicular discontinuity.

C. Revision tympanoplasty without ossicular reconstruction: The graft is intact and mobile; this would not bridge the demonstrated conductive defect.

D. Bone-conduction implantation without discussing ossiculoplasty: Bone-conduction rehabilitation is an alternative, but favourable middle-ear conditions and a mobile footplate make TORP reconstruction a reasonable anatomical choice.

E. A total ossicular replacement prosthesis from tympanic membrane graft to the mobile stapes footplate: With no stapes superstructure and a mobile footplate, a total prosthesis couples the reconstructed drum to the footplate; stability, cartilage protection and ventilation determine outcome.

What if the scenario changed?

If the footplate were fixed or the middle ear repeatedly retracted and poorly aerated, prosthetic reconstruction would be less favourable and bone-conduction options should be discussed.
