Bilateral simultaneous hearing preservation mastoidectomy in otogenic meningitis.

Bilateral simultaneous hearing conservation mastoidectomy has not been previously documented. We present our experience with this procedure. Three patients with pyogenic meningitis secondary to bilateral unsafe ears had hearing preservation surgeries of both ears in a single sitting. Although ear surgery carries risk of inner ear damage, in our series there was no deterioration of inner ear function in the 6 ears operated on. The air conduction threshold improved in 3 (50%) of the ears. When meningitis results from bilateral otogenic foci as in our series, simultaneous mastoidectomy in both ears may be the preferred method of treatment to eradicate the source of infection.
