Anatomical and functional reconstruction of old radical mastoidectomy cavities by obliteration tympanoplasty.
One hundred and seventeen patients who had previous radical mastoidectomies, atticotomies or Bondy operations were operated on between 1973 and 1984. An open technique with obliteration and traction meatoplasty was used in one stage in 19 ears (normal mucosa in mesotympanum) and in 2 stages in 98 ears (poor mesotympanum which needed to be dissected and covered with silastic sheeting). The second stage was performed 12 to 18 months later. Closure of the tympanic membrane was achieved in 93% of ears at the first stage. In 6 ears out of 81 second stages, residual cholesteatoma was found in the mesotympanum. No residual cholesteatoma was subsequently observed behind the flap but only 4 ears were checked behind the flap at the second stage. An air-bone gap within 20 dB was achieved in 85% of ears if the stapes was intact and surgery was performed in one stage, and in 55% of ears of the stapes was intact and surgery performed in 2 stages. If the crura were missing, an air-bone gap within 20 dB was achieved in 57% of ears in 2 stages.
