1/37. subcutaneous emphysema and pneumomediastinum after dental extraction.Pneumomediastinum, pneumothorax, and subcutaneous emphysema can occur occasionally after a surgical procedure. Facial swelling is a common complication of dental management. The occurrence of subcutaneous emphysema, pneumothorax, and pneumomediastinum after dental procedures is rare. We present a case with subcutaneous emphysema of the upper chest, neck, chin, and pneumomediastinum after a tooth extraction and discuss the possible mechanism of subcutaneous emphysema. To prevent these complications during dental procedures, dental hand pieces that have air coolant and turbines that exhaust air in the surgical field should not be used.- - - - - - - - - - ranking = 1keywords = tract (Clic here for more details about this article) |
2/37. Surgical emphysema and pneumomediastinum complicating dental extraction.Subcutaneous and mediastinal emphysema is a rare complication of dental extraction and the use of air turbines has often been implicated. We describe a case which highlights a serious complication of the use of an air rotor for the removal of a right second mandibular molar.- - - - - - - - - - ranking = 1keywords = tract (Clic here for more details about this article) |
3/37. Computed tomography of emphysema following tooth extraction.Subcutaneous and tissue space emphysema following surgical extraction of mandibular third molars is a rare and serious complication of dental surgery. Recognition of mediastinal emphysema following surgical extraction is difficult because there are no absolute clinical symptoms and signs. We present two cases of emphysema following extraction of a lower third molar and discuss the contribution of CT to the early recognition of the presence and spatial migration of air and to clinical management.- - - - - - - - - - ranking = 1.4keywords = tract (Clic here for more details about this article) |
4/37. Bilateral pneumothorax with extensive subcutaneous emphysema manifested during third molar surgery. A case report.This report describes a case of bilateral pneumothorax with extensive subcutaneous emphysema in a 45-year-old man that occurred during surgery to extract the left lower third molar, performed with the use of an air turbine dental handpiece. Computed tomographic scanning showed severe subcutaneous emphysema extending bilaterally from the cervicofacial region and the deep anatomic spaces (including the pterygomandibular, parapharyngeal, retropharyngeal, and deep temporal spaces) to the anterior wall of the chest. Furthermore, bilateral pneumothorax and pneumomediastinum were present. In our patient, air dissection was probably caused by pressurized air being forced through the operating site into the surrounding connective tissue.- - - - - - - - - - ranking = 0.2keywords = tract (Clic here for more details about this article) |
5/37. Plastic bronchitis mimicking foreign body aspiration that needs a specific diagnostic procedure.OBJECTIVE: To report two children admitted to our emergency department with respiratory failure, one for status asthmaticus with pneumomediastinum and requiring mechanical ventilation and the other for high suspicion of foreign body aspiration. INTERVENTIONS: bronchoscopy revealed obstructive plugs and permitted their extraction and their identification as bronchial casts after the immersion in normal saline. Allergy was suspected in the first one, and Hemophilus influenzae infection was present in the second. The outcome was favorable. CONCLUSIONS: Plastic bronchitis is an infrequent cause of acute life-threatening respiratory failure that can mimic foreign body aspiration or status asthmaticus. Bronchoscopic extraction must be performed urgently in the case of severe obstruction. This entity is probably underestimated as the casts with their specific ramifications are difficult to recognize. We recommend the immersion in normal saline of all plugs discovered in children with predisposing diseases mainly represented by infections, allergy, acute chest syndrome, and congenital cardiopathies.- - - - - - - - - - ranking = 0.4keywords = tract (Clic here for more details about this article) |
6/37. pneumoperitoneum without perforation of the gastrointestinal tract.pneumoperitoneum (PP) is usually the result of perforation of the gastrointestinal (GI) tract with associated peritonitis. However, other rare causes, including spontaneous PP incidental to intrathoracic, intra-abdominal, gynecologic, and miscellaneous other origins not associated with a perforated GI tract have been described in the literature. Six cases of PP without any perforated GI tract are reported. Three patients with generalized peritonitis underwent exploratory laparotomy or laparoscopy when clinical examinations suggested an acute abdomen. At surgical procedure, perforated pyometra, perforated liver abscess and a ruptured necrotic lesion of a liver metastasis were documented in these patients, respectively. We also saw 3 PP patients not associated with peritonitis. Two patients with PP caused by pneumatosis cystoides intestinalis were encountered, 1 was managed conservatively and the other received diagnostic laparoscopy. A patient in whom pneumomediastinum and pneumoretroperitoneum were accompanied by PP caused by an alveolar rupture based on decreased pulmonary compliance due to malnutrition was managed conservatively. The history of the patient and knowledge of the less frequent causes of PP can possibly contribute towards refraining from exploratory laparotomy in the absence of peritonitis.- - - - - - - - - - ranking = 8.2905255126382keywords = gastrointestinal tract, tract (Clic here for more details about this article) |
7/37. Massive subcutaneous emphysema following routine endotracheal intubation.Upper aerodigestive tract injury after endotracheal intubation is a rare but serious complication. The case of a 57-year-old female, who developed extensive neck and pneumomediastinum following a knee arthroscopy under general anaesthesia, is presented. Possible mechanisms of injury and management options are discussed.- - - - - - - - - - ranking = 0.2keywords = tract (Clic here for more details about this article) |
8/37. Pneumomediastinum due to intractable hiccup as the presenting symptom of multiple sclerosis.Pneumomediastinum and subcutaneous emphysema generally occurs following trauma to the esophagus or lung. It also occurs spontaneously in such situations of elevating intra-thoracic pressure as asthma, excessive coughing or forceful straining. We report here on the rare case of a man who experienced the signs of pneumomediastinum and subcutaneous emphysema after a prolonged bout of intractable hiccup as the initial presenting symptoms of multiple sclerosis.- - - - - - - - - - ranking = 1keywords = tract (Clic here for more details about this article) |
9/37. Cervicofacial emphysema and pneumomediastinum following pediatric adenotonsillectomy: a rare complication.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.- - - - - - - - - - ranking = 0.2keywords = tract (Clic here for more details about this article) |
10/37. Cervicofacial, retropharyngeal and mediastinal emphysema: a complication of orbital fracture.Retropharyngeal and mediastinal emphysema is associated with traumatic aerodigestive tract injury, and may be associated with potentially severe and even life-threatening complications. Retropharyngeal emphysema or pneumomediastinum, in the absence of severe trauma to the visceral organs, is rare following facial fractures. We report a case of extensive subcutaneous emphysema extending to the retropharyngeal space and mediastinum following an orbitozygomatic fracture.- - - - - - - - - - ranking = 0.2keywords = tract (Clic here for more details about this article) |
