Camouflaging Facial Emphysema, as is defined in this paper, is the result of a simple technique used by the patient to deform his face in order to prevent recognition at a police identity parade. The patient performs two punctures in the mucosa at the rear of the upper lip and, after several Valsalva manoeuvres, manages to deform his face in less than 15 min by inducing subcutaneous facial emphysema. The examination shows an accumulation of air in the face, with no laterocervical, mediastinal or thoracic affectations. The swelling is primarily observed in the eyelids and the orbital and zygomatic regions, whereas it is less prominent in other areas of the face. Patients therefore manage to avoid recognition in properly conducted police identity parades. Only isolated cases of self-induced facial emphysema have been reported to date among psychiatric patients and prison inmates. However, the facial emphysema herein described exhibits specific characteristics of significant medical, deontological, social, police-related, and legal implications.
伪装面部皮下气肿，如本文所述，是患者为了在警方的身份辨认中避免被认出来而采用的一种简单技术，导致的结果。患者在上唇黏膜后部做两个穿刺，然后进行几次瓦尔萨尔瓦动作，在不到 15 分钟的时间内成功地通过皮下面部气肿使面部变形。检查显示面部有空气积聚，没有颈侧、纵隔或胸部影响。肿胀主要发生在眼睑和眶周及颧骨区域，而在面部的其他区域则不太明显。因此，患者可以在警方进行的适当身份辨认中避免被认出。迄今为止，只有在精神科患者和监狱囚犯中报告了少数几例自我诱导的面部皮下气肿病例。然而，此处描述的面部皮下气肿具有重要的医学、道德、社会、警察相关和法律影响的特定特征。
