Refractory sphenoid wing osteomyelitis as a complication of orbital decompression.

Osteomyelitis of the sphenoid wing is a rare clinical entity that can result in significant morbidity due to cranio-orbital infection. This entity has never previously been described as a complication of orbital decompression. An elderly patient developed relapsing orbital cellulitis and cranio-orbital abscesses following orbital decompression. Multiple attempts at incision and drainage with extended antibiotic therapy failed to eliminate the infection. The patient's clinical course was indicative of sphenoid osteomyelitis at the prior decompression site. A combined craniotomy-orbitotomy with debridement of the involved portion of the sphenoid resulted in resolution of the patient's clinical symptoms. Surgeons should be aware of the possibility of this rare infection following any surgery in which bone is structurally modified or removed, including orbital decompression.
