Subcutaneous Emphysema Secondary to Dental Procedure-Case Report

Subcutaneous emphysema of the head and neck region secondary to dental procedures is uncommon and typically associated with high-pressure dental devices, such as air-driven handpieces or air-water syringes. Differential diagnosis for pneumoparotitis and necrotizing fasciitis is crucial. Treatment of subcutaneous emphysema focuses on prophylactic antibiotics and the prevention of respiratory and cardiac complications. The accumulated air is typically absorbed spontaneously within 2 weeks, without complications or morbidity. However, severe complications such as airway compression or infection along the fascial plane have been documented. We report the case of an 82-year-old man who developed extensive subcutaneous emphysema of the head and neck region following a dental procedure. After hospitalization and the administration of intravenous antibiotics for 7 days, the patient's swelling decreased and had resolved by 2 weeks after discharge.

本部經歷1名82歲男性於牙科診所接受處置後，導致頭頸部廣泛性皮下氣腫，其住院接受廣效性抗生素7天後恢復良好且顯著消腫。出院後持續追蹤1個月，皮下氣腫完全消失。皮下氣腫是指空氣或其他氣體聚積在皮下軟組織，很少發生在一般牙科處置後，與高速氣鑽式手機或水氣槍噴頭相關，治療以維持呼吸道暢通與預防性抗生素為主，需要與腮腺氣腫及頭頸部壞死性筋膜炎做鑑別診斷，皮下氣腫通常兩週內會自行吸收且預後良好，但嚴重者可能造成呼吸道壓迫或併發感染症。由於牙科處置後皮下氣腫在文獻少見，可能有危及生命的併發症，特此提出報告。
