“…Diagnosis of subcutaneous emphysema is important because, if unnoticed, it can lead to various complications, such as pressure on the orbit, which can cause blindness [ 9 , 13 ], compression of the upper airway that sometimes requires intubation of the patient [ 1 , 3 , 14 ], and nerve compression (such as that of the recurrent laryngeal nerve) that causes vocal cord paresis [ 1 ]. Furthermore, subcutaneous emphysema may extend to the thorax, causing pneumopericardium [ 19 , 20 ] or pneumomediastinum [ 1 , 3 , 8 , 10 – 12 , 14 – 17 , 19 – 28 ]. Pressurized air can rupture the mediastinal pleura and cause pneumothorax [ 11 , 19 , 26 ].…”
