Pneumomediastinum and subcutaneous emphysema of the neck and thorax can occur exceptionally following a dental procedure. A case is described of acute subcutaneous emphysema of the lateral region of the neck and thorax associated with pneumomediastinum during a dental extraction with an air and water cooled turbine burn drill.

Mediastinal and subcutaneous emphysema have been reported as a consequence of deliberate manipulations of the breathing pattern producing a Valsalva-like maneuver in healthy subjects. We present a case of pneumomediastinum, pneumothorax and subcutaneous emphysema occurring in a normal volunteer after repeated measurements of the PEmax.

Severe subcutaneous emphysema following arthroscopy of the shoulder developed in a 62-year-old man. It subsequently evolved into pneumomediastinum with respiratory distress, but the patient recovered spontaneously. To our knowledge, this constitutes the first report of pneumomediastinum caused by subcutaneous emphysema in the shoulder.

A 66-year-old woman developed massive subcutaneous emphysema following intubation. Acute thoracic restriction developed resulting in life-threatening respiratory acidosis. The patient could not be ventilated with conventional means. A tracheostomy was performed to decompress the chest and mediastinum with rapid resolution following. Although ventilatory failure from subcutaneous emphysema is ve...

Subcutaneous emphysema (SCE) mimicking diaphragmatic hernia on X-ray is hitherto unreported and this case has been presented with the aim to alert the clinician about this unusual presentation of SCE to avert undue panic and initiate appropriate evaluation and management. This case also reemphasizes the importance of a thorough clinical examination, which probably could have revealed the subcut...

Subcutaneous emphysema is a rare complication in oral surgery. In most cases, it resolves spontaneously. However, air might disperse into deeper facial spaces causing life-threatening complications such as compression of the tracheobronchial tree or the development of pneumomediastinum. Moreover, microorganisms might spread from the oral cavity into deeper spaces. Hence, rapid diagnosis of subc...

Introduction. Thoracic subcutaneous emphysema may be caused by various pathologies. In mechanically ventilated patients, timely diagnostic workup is particularly important, as the presence of subcutaneous surgical emphysema may indicate pneumothorax, representing a risk factor for the development of life threatening tension pneumothorax. Thoracic ultrasound is of proven value for the detection ...

ly. Physical examination showed that the patient could freely uplift his head for more than 5 s, and had a strong handshake with the normal train-of-four ratio. Although snoring persisted, the patient could not tolerate oropharyngeal airway. Marked subcutaneous crepitus was now obvious, especially in the area of the cheek, neck, chest, abdomen, and limbs. Subcutaneous emphysema was apparent. Af...

Subcutaneous emphysema in the head and neck is a well known clinical condition. It is an uncommon clinical complication of dental treatment caused by forceful injection of air into the loose connective tissue below the dermal layer. The trapped air is often limited by subcutaneous space in the head and neck. This paper presents a clinical case in which subcutaneous emphysema developed immediate...

and was discharged after 8 days. Colonoscopy is a common and safe diagnostic and curative procedure. The incidence of perforation is 0.19 to 0.21% and usually happens after therapeutic procedures.1 Sigmoid colon is frequently involved. Pneumomediastinum and subcutaneous emphysema occurs in exceptional cases.2 The choice to perform conservative treatment or endoscopic clipping3-5 is determined b...
