Perforation of the cervical esophagus in the course of attempted intubation of the trachea is a very rare accident, or at least rarely reported. Over the past 11 years, 12 patients ranging in age from 44 to 72 years were treated in our unit. If suspected, esophageal perforation is easy to diagnose when intubation has been difficult or when the patient complains of dysphagia and neck pain. Subcutaneous cervical emphysema appears early. All the patients who were operated upon early made an uneventful and prompt recovery. In those subjected to delayed operation (more than 12 hours) or nonoperative treatment, the mortality rate was 56 percent and recovery was achieved only after long and difficult treatment.

Although a rare complication of labor, subcutaneous emphysema and pneumomediastinum (Hamman's syndrome) must be considered in the parturient complaining of chest or neck pain, dysphagia, or shortness of breath. With conservative management, the prognosis is favorable. The case presented is the first of Hamman's syndrome complicating the labor of a twin gestation. The pathophysiology, symptoms, and management guidelines for the syndrome are reviewed.

Four cases of acute laryngeal fracture that demonstrate the history and clinical findings characteristic of blunt laryngotracheal trauma are presented. Symptoms in these patients included shortness of breath, neck pain, dysphasia, dysphonia, and hemoptysis. Physical examination findings suggesting acute laryngeal injury included pain on palpation of neck, swelling or edema of the neck, subcutaneous emphysema, and loss of landmarks in the neck. All four patients were admitted to the surgical intensive care unit and had the diagnosis of laryngeal fracture confirmed at laryngoscopy. Airway obstruction is a potential complication in all patients sustaining blunt laryngotracheal trauma. Early diagnosis and management may lead to a good outcome, as with these four patients.

Spontaneous pneumomediastinum, or Hamman's syndrome, is a rare condition which may present with the symptoms of chest pain, dyspnoea, dysphagia, or neck pain. The signs of subcutaneous emphysema and Hamman's crunch (the presence of a crepitance sound that varies with the heartbeat on auscultation of the precordium) are usually present. A case of this syndrome occurring in an elderly patient with none of the recognised risk factors is presented.

Pneumomediastinum (spontaneous, iatrogenic and traumatic) is a relatively uncommon infrequently reported entity. The most common cause is the rupture of marginal pulmonary alveoli, allowing bubbles of air to dissect along the vascular sheaths and connective tissue planes to the mediastinum. Rupture of the trachea or thoracic traumas are other causes of pneumomediastinum. The most common presenting complaint was retrosternal pain, dyspnea, dysphagia, weakness and neck pain. Physical finding revealed: subcutaneous emphysema extended to face, chest or neck, and Hamman's sign. Chest X-ray was made in all cases and diagnosis was completed with chest CT scan and tracheoscopy. We present our series of 34 PM between January 1.1993 to July 31.1995 and discuss about etiology, diagnosis and treatment of this entity.

The purpose of this study was to determine the possible causes, clinical findings, and associated complications of pneumomediastinum in children. Medical records from January 1985 to December 1994 were retrospectively reviewed at Children's Hospital Medical Center of Akron using International Classification of Diseases, ninth revision, codes to identify cases of pneumomediastinum. The medical causes, nontraumatic and noniatrogenic, of pneumomediastinum were studied; intubated or trauma patients and patients having undergone procedures were excluded. Neonates were also excluded. Twenty-nine cases of pneumomediastinum were identified. Two patients (7%) had recurrent pneumomediastinum. Only the first episode of pneumomediastinum was included in the data analysis. Twenty males (69%) and nine females (31%) were affected. The most common medical causes of pneumomediastinum were asthma exacerbations (17/59%) and infections (8/28%). Over the 10-year period, the prevalence of pneumomediastinum in children with asthma exacerbations was 0.2% (21/10,472); 1% (1/126) in children with airway foreign bodies and 0.2% (1/351) in children with esophageal foreign bodies. The most common signs and symptoms were subcutaneous emphysema (22/76%), sore throat or neck pain (11/38%), and Hamman's crunch (3/10%). The most common complication was pneumothorax with small pneumothoraces in 2 patients (7%) and a tension pneumothorax in 1 asthmatic with recurrent pneumomediastinum. Patients without sore throat or neck pain and patients admitted to the intensive care unit had greater hospital lengths of stay. Pneumomediastinum appears to be uncommon in children. The most common medical causes were asthma and infections. The most common signs and symptoms were subcutaneous emphysema, sore throat or neck pain, and Hamman's crunch. The most common complication was pneumothorax. The clinical significance of pneumomediastinum is its cause and association with significant complications.

We describe a 42-year-old man with dermatomyositis and interstitial lung disease who presented with anterior neck pain and dyspnoea. Chest radiographs showed subcutaneous emphysema, pneumomediastinum and diffuse reticulonodular infiltration in both lungs. After the administration of high doses of prednisolone, an improvement of pulmonary function and respiratory symptoms was observed but the pneumomediastinum persists 12 months after diagnosis, and without any complication. We review the cases that have been reported thus far of pneumomediastinum associated with dermatomyositis and discuss the possible mechanisms involved. We conclude that pneumomediastinum is not an uncommon complication of dermatomyositis and that its aetiopathogenesis remains very unclear.

Spontaneous cervical emphysema and pneumomediastinum, occurring in the absence of previous disorders or provocating factors, is very rare. The predominant symptoms are retroesternal pain, dyspnea, dysphagia and neck pain. The diagnosis is established radiologically. The evolution is generally good and conservative therapy leads to recovery in most patients. We present an unusual case of pneumomediastinum, cervical and retropharyngeal emphysema that spread to cavum; the suspected symptom was voice alteration as reported by the parents.

Spontaneous pneumomediastinum (SPM) is an uncommon disease defined as a non-traumatic presence of free air in the mediastinum, without underlying disease. We present a 13-year- old boy who was previously in a perfect health, who was presented with subcutaneous cervical emphysema, dysphagia, chest and neck pain. The chest roentgenogram revealed the presence of subcutaneous emphysema without any other abnormal findings. A computer tomography (CT) scan was obtained, and this confirmed the existence of subcutaneous cervical emphysema and also the presence of pneumomediastinum. The child's progress was uneventful and after 6 days he was discharged from the hospital in excellent clinical condition. We propose that chest CT is useful, in less obvious cases of SPM, to detect the free air in the mediastinum and probably SPM is underdiagnosed in clinical practice in the young people.

Cervicofacial emphysema and pneumomediastinum are rarely observed sequelae of surgical intervention in the upper aerodigestive tract. It is a potentially life-threatening condition but the majority of cases are self-limiting and benign. Symptoms include chest pain, neck pain, dyspnea and odynophagia. A case occurring after adenotonsillar surgery in a 7-year-old child is presented. This report highlights this unusual complication and its potential to delay the postoperative recovery following adenotonsillectomy.
