下顎智歯抜歯時に生じた皮下気腫・縦隔気腫の２例

Abstract

Two cases of subcutaneous and mediastinal emphysema caused by removal of lower third molars with an air turbine are reported. Case 1: A 25-year-old woman was referred to our hospital immediately after removal of a left lower third molar with an air turbine. She complained of bilateral swelling of the cheeks and submandibular regions and slight dyspnea. A computed tomographic (CT) scan revealed aerodermectasia from the left submandibular region to the right temporal region and bilateral cervical region. The CT scan also showed mediastinal emphysema. The patient was hospitalized and given a drip intravenous infusion of antibiotics for 3 days. Recovery was uneventful. Case 2: A 32-year-old woman complained of bilateral swelling of the cheeks at the time of extraction of the left lower third molar with an air turbine. She was referred to our hospital for further evaluation. A CT scan revealed aerodermectasia from the left submandibular region to the left temporal and bilateral cervical regions, associated with mediastinal emphysema. Antibiotics were administered by intravenous drip infusion for 3 days, and she recovered.
