Recurrent frontal sinusitis complicating orbital decompression in Graves' disease.

An unusual case of recurrent frontal sinusitis with abscess formation secondary to orbital decompression for Graves' disease is described. The infection was refractory to antibiotics treatment, external drainage and the sinus obliteration procedure. Since the sinus outflow was obstructed by prolapsing tissue following excessive removal of the orbital walls, sinus re-aeration by supporting the prolapsed tissue with a silastic sheet and stenting the sinus drainage tract was attempted. This led to a complete resolution of the infection with an excellent long-term result.
