Middle ear gas generation in myringoplasties.
No Gelfoam was used to support the vein in 10 simple underlay vein graft myringoplasties. Computed tomographic studies 24 hours postoperatively showed gas filling 75% to 100% of the middle ears in three ears. The epitympanum and mastoid were also evaluated. Apparently, in some ears the middle ear generates gas in the immediate postoperative period to support fresh vein grafts.
