Subcutaneous cervicofacial, mediastinal emphysemas are complications associated with head and neck surgery, trauma, infectious processes, tooth extraction. Drill cooling stream and dental syringe air ject are the sources of high pressure air that may enter exposed soft tissue. Since the introduction of the high-speed air turbine drill in the 1960s, The incidence of iatrogenic subcutaneous emphysema has increased. Most cases begin to resolve after 2 to 3 days and residual swelling is usually minimal at the end of 7 to 10 days. Surgical approach is not advised because it is likely to be ineffective. The differential diagnosis of neck swelling after dental procedure includes hematoma, cellulitis, angioedema, allergic reaction, subcutaneous emphysema. We report a rare case of patient with subcutaneous cervicofacial emphysema and mediastinal emphysema secondary to third molar extraction.

Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully recovered after eight days of conservative treatment. The cause of this case was the penetration of high-pressure air through the gingival sulcus, which had a weakened gingival attachment. This case indicated that dentists should be careful to prevent subcutaneous emphysema during common dental treatments using a high-speed hand piece and gingival retraction cord.

Subcutaneous emphysema and pneumomediastinum is a relatively uncommon phenomenon. It may occur secondary to dental treatment using high-speed air turbine handpieces, especially after extraction of tooth. Subcutaneous emphysema is often limited only to the areas of head and neck, but also can involve deeper structures. Thorough examination and conservative treatment of these problems are essential in preventing life-threatening complications such as airway obstruction and mediastinitis. The subject of this report is a 57-year-old woman with subcutaneous emphysema and pneumomediastinum during the extraction of maxillary third molar using high-speed air turbine handpiece. If there isn't any appropriate measure, severe complications may occur. Therefore it is important to be well-informed of proper diagnosis and treatment. This article shall present a case report with literature review.

Infantile lobar emphysema is a pulmonary hyperinflation state that has the clinical features of an air block syndrome characterized by bronchial cartilaginous abnormalities or unknown origin. Left upper lobe was affected in most of the reported infantile lobar emphysema. Infantile lobar emphyema is divided into two categories. e.g., congenital and acquired. We have experienced a case of left lower lobe involved infantile lobar emphysema which had undergone left pneumonectomy. She had progressive signs of tension accompanied by mediastinal displacement, ventilatory and circulatory failure in infant period. Because of the combined left upper lobe hypoplasia, left pneumonectomy was performed. And there was no cartiliginous abnormality in pathologic finding. This is the first domestic case which was affected in the lower lobe and successful surgical repaired.

Subcutaneous emphysema is a benign condition following trauma (pneumothorax and oropharyngeal), cervical or thoracic procedures, and mediastinal infection. However, severe subcutaneous emphysema may be related to serious complications such as respiratory failure, airway compromise, and tension- related phenomena. Many alternative therapies have been tried to treat patients with this condition. We report our experience with vacuum-assisted closure therapy for treating patients with severe subcutaneous emphysema.

The coronavirus disease 2019 (COVID-19) pneumonia is a recent outbreak in mainland China and has rapidly spread to multiple countries worldwide. Pulmonary parenchymal opacities are often observed during chest radiography. Currently, few cases have reported the complications of severe COVID-19 pneumonia. We report a case where serial follow-up chest computed tomography revealed progression of pulmonary lesions into confluent bilateral consolidation with lower lung predominance, thereby confirming COVID-19 pneumonia. Furthermore, complications such as mediastinal emphysema, giant bulla, and pneumothorax were also observed during the course of the disease.

Video-assisted thoracic surgery[VATS] has recently evolved as an alternative to thoracotomy for several thoracic disorders. Between March 1993 and September 1993, 42 patients underwent VATS at Gil General Hospital. They were diagnosed as spontaneous pneumothorax in 34[81.0%], mediastinal mass in 5, congenital lobar emphysema in 1, traumatic hemothorax in 1, and sarcoidosis in 1. For pneumothorax, wedge resection of bullae or blebs was done in 18 patients, wedge resection and limited parietal pleulectomy in 13, and only pleulectomy in 2. And excision for mediastinal mass in 5, hematoma evacuation for chronic hemothorax in 1, biopsies of mediastinal lymph node and lung for confirming sarcoidosis in 1, and lobectomy of left upper lobe for congenital lobar emphysema in the child of 12 years. The period of chest tube drainage and postoperative hospitalization averaged 3.8 days [range, 1 to 11 days] and 5.9 days [range, 2 to 18 days]. Three complications occurred in 3 patients with pneumothorax [7.1%, 2 recurrent pneumothorax and 1 postoperative bleeding], and the conversion to open thoracotomy was done in 1 due to massive air leak. The causes of postoperative air leak were speculated and the techniques for saving expensive Endo-GIA staplers are described in this paper. VATS is safe and offers the benefits of reduced postoperative pain and rapid recovery. Our experience indicates a markedly expanded role for VATS in the diagnosis and treatment of various thoracic diseases.

The objective is to review a case of pneumoparotitis and to discuss how knowledge of this unique presentation is important when making differential diagnoses in emergency medicine. A patient with recurrent subcutaneous emphysema of the head and neck is reviewed. Stenson's duct demonstrated purulent discharge. Physical examination revealed palpable crepitance of the head and neck. Fiberoptic laryngoscopy and barium esophagram were normal. Computed tomography demonstrated left pneumoparotitis and subcutaneous emphysema from the scalp to the clavicles. This is an unusual presentation of pneumoparotitis and malingering. Emergency physicians should be aware of pneumoparotitis and its presentation when creating a differential diagnosis for pneumomediastinum, which includes more life-threatening diagnoses such as airway or esophageal injuries.

A miniature pinscher and two Maltese dogs were present with dyspnea, and radiography and computed tomography (CT) were performed. All dogs were diagnosed with giant bullous emphysema of the massive, hyperexpanded, and hypoattenuating bulla causing contralateral mediastinal shift. Giant bullous emphysema, the rarest form of bullous lung disease, is defined as a bulla that fills more than 30% of the hemithorax, and multi-detector CT scanning could provide the useful information to confirm a diagnosis of giant bullous emphysema in older dogs. The radiographic and computed tomographic features for giant bullous emphysema were described.
