Introduction:
Etiology of head-and-neck emphysema is mainly infectious (cellulitis) or traumatic (rupture of the aerodigestive tract mucosa, usually in the larynx and trachea).
Case Report:
We report a case of head-and-neck and mediastinal emphysema due to oral hyperpressure inducing parotid acini rupture. The aim is to highlight the importance of precise interview of patient and family so as to identify this mechanism.
Discussion:
Pneumoparotid is a rare cause of swelling induced by insufflation into Stensen's duct. This reflux is caused by intra-oral hyperpressure, and can cause extensive subcutaneous emphysema induced by capsule rupture. The disorder is common in players of wind instruments and glass-blowers. Positive diagnosis is based on focused interview, looking for trigger factors, and on imaging assessment. Evolution is reported to be spontaneously favorable with simple antibiotherapy. Patient education is the best means of limiting recurrence.
Conclusion:
In case of cervical emphysema, it is important to determine the mechanism of onset and explore for pneumoparotid on CT, so as to adapt treatment and prevent possible recurrence.

Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
