Abstract

Background Subcutaneous emphysema related to dental procedures is well documented in literature. It usually occurs during or within minutes to hours after dental treatment and can be easily diagnosed by the presence of crepitus on palpation. Although it is self-limiting, it can develop to potentially life-threatening complications. Case presentation To the authors knowledge, this is the first report documenting the development of subcutaneous emphysema in a 22-year-old Egyptian female during lower surgical gingival depigmentation using NSK high speed, air driven handpiece operated at 0.25 MPa. Sudden swelling developed involving the right side of the face and immediate diagnosis of subcutaneous emphysema was made on the basis of the presence of crepitus during palpation of the swollen area. Intraoral examination revealed small tissue laceration of the loosely attached alveolar mucosa through which the pressurized air might have passed into the fascial spaces. Complete resolution of the swelling occurred after 7 days without further complications. Conclusion Straightforward surgical procedures, such as gingival depigmentation, can be complicated by the development of subcutaneous emphysema. The crucial role of dentists is to be aware of its signs and to immediately diagnose and manage it to avoid further complication.
