阻生齒拔除手術致皮下氣腫－病例報告

皮下氣腫泛指氣體不正常地出現於皮下組織。由於皮下氣腫易與其它導致顏面部腫脹的成因混淆，且皮下氣腫可能引起嚴重併發症，並造成生命危險，因此牙醫師應早期鑑別診斷，並積極預防併發症產生。皮下氣腫在牙科治療中是少見的併發症，多發生在使用氣動高速手機進行拔牙手術的案例，也常在治療下顎後牙時出現。本病例報告提出拔除下顎第三大臼齒時，因牙科高速手機故障而造成皮下氣腫。因本病例之術式、器械、治療位置皆為牙科治療中伴有皮下氣腫併發症之常見因子，故提出報告及相關文獻回顧。

Subcutaneous emphysema is an abnormal appearance of gas in the subcutaneous tissue. Because subcutaneous emphysema may be easily confused with other facial swelling causes and lead to severe complications and life-threatening situations, dentists should make an early differential diagnosis and prevent the complications actively. Subcutaneous emphysema is an uncommon complication in dental treatments but could occur in teeth extraction using air-driven handpieces and posterior mandible teeth extraction. In this case report, we describe a case of subcutaneous emphysema caused by the failure of the high-speed handpiece during the removal of the third molar of the lower jaw. We present this report and review related literature because the surgical procedures, instruments, and treatment location, in this case, are common factors associated with the complication of subcutaneous emphysema in dental treatment.
