Introduction: Subcutaneous and mediastinal emphysema is a rare complication after tonsillectomy. This case presentation and literature review summarizes the existing literature on this unusual complication.  Materials and Methods: This study presents a case of a 21-year-old man who developed a cervical subcutaneous emphysema 6 days after tonsillectomy, whereby conservative treatment produced sp...

Cervicofacial subcutaneous emphysema is a rare complication of dental procedures with an air turbine or syringe, and dentists and oral surgeons sometimes encounter mediastinal emphysema following the presentation of extensive subcutaneous emphysema. Most emphysema occurs incidentally during tooth extraction, restorative treatment, or endodontic treatment, with only a few cases reported of cervi...

OBJECTIVE To evaluate the difference in the clinical features of mediastinal emphysema as classified into three groups based on etiology; patients in whom it was spontaneous with unknown etiology (A group), those in whom it was secondary to bronchial asthma (B group), and those in whom it was secondary with other respiratory diseases (C group). PATIENTS Forty-three cases (45 episodes) with me...

Mediastinal emphysema is a status of gas retention in mediastinum, usually caused by airway system injury or esophagus rupture. Healthy people without trauma and basic disease emerging unexplained mediastinal emphysema are called idiopathic mediastinal emphysema. While tension pneumomediastinum is an exceptional and potentially lethal condition, the increased intramediastinal pressure with a se...

PURPOSE To report a rare case of periorbital emphysema concurrent with cervicofacial and mediastinal emphysema in an elderly woman who underwent upper gastrointestinal endoscopy for chronic liver disease. CASE REPORT An elderly woman with decompensated chronic liver disease presented with features of periorbital, facial, and mediastinal emphysema, characterized with crepitant swelling over th...

background: congenital lobar emphysema, also called infantile lobar emphysema, is a respiratory disease that occurs in infants when air enters the lungs and cannot leave easily. it results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress. in this study, we present a case of endobronchial polyp mimicking congenital lobar emphysema. case presentati...

Subcutaneous cervical and mediastinal emphysema usually can occurs as a result of surgery or trauma. Spontaneous cervical subcutaneous emphysema and pneumomediastinum, occurring in the absence of previous disorders or provocating factors, is very rare. The following case report of spontaneous cervical and mediastinal emphysema is assumed to be the first of its kind in Korea. The patient has bee...
