Descending necrotizing mediastinitis: a complication of dental implant surgery.

Abstract

The placement of osseointegrated dental implants is considered a minimally invasive procedure with a low complication rate. Reported complications include local trauma to neurovascular structures, mandible fractures, sinusitis, and localized gingivitis. Major life-threatening complications are extremely rare. Severe infection has not been reported in a review of the English literature. Case study. We present a case of life-threatening deep neck space infection resulting in descending necrotizing mediastinitis following osseointegrated dental implant placement. Treatment included intravenous antibiotics, aggressive neck debridement, and removal of the infected dental implants. Severe infection can result from the placement of dental implants. Principles of treatment include antibiotics, surgical drainage and debridement, and careful assessment and removal of the involved implants.
