Tracheobronchial ruptures are rare but potentially lifethreatening events. We report on the case of a 34-year-old suicidal unrestrained car driver, who developed subcutaneous and mediastinal emphysema and right-sided haematothorax following blunt thoracic trauma. Fibreoptical inspection of the tracheobronchial system revealed a rupture (approximately 2 cm in length) of the pars membranacea of the trachea ending shortly above the carina. CT-scan confirmed the diagnosis of mediastinal emphysema, tracheal rupture and, in addition, left-sided pulmonary contusion. A repair of the tracheal tear was performed by right-sided thoracotomy using a double-lumen tube. The left-sided double-lumen tube was used postoperatively to achieve respirator ventilation with low pressure on the tracheal lumen and on the suture of the tracheal tear. On the other hand, sufficient airway pressure with PEEP for the left lung showing contusion could be provided, using the endobronchial tube. The postperative course was without complications. The patient was on respiratory support for three days due to his-pulmonary contusion. Following final endoscopic control of the trachea he was discharged from the ICU one week after the trauma. The clinical and radiological signs of tracheobronchial ruptures are discussed (respiratory distress, haemoptysis, cyanosis, localised pain, hoarseness, coughing, dysphagia, stridor, subcutaneous emphysema and pneumothorax, tension pneumothorax, mediastinal emphysema). Fibreoptic bronchoscopy is the present gold standard for confirming the diagnosis. The surgical and anaesthesiological approach to the management of tracheobronchial ruptures is described reviewing the current literature.

Percutaneous dilatational tracheostomy (PDT) is being increasingly used. Concerns have been raised as to its safety, especially when it is done at the bedside. A prospective evaluation was conducted of 100 consecutive, unselected critically ill patients with PDT. The mean intensive care unit (ICU) stay before PDT was 12 days. One surgeon performed PDT alone (5 cases) or assisted residents (95 cases) in all operations; 84 were performed at the ICU bedside. Only the first six patients were taken to the operating room solely for tracheostomy. A modified technique was used: (1) the endotracheal tube was left in place during sequential dilations; (2) dilators were inserted in a 60-degree cephalad orientation to the skin and directed caudally after penetration of the anterior tracheal wall; (3) a digit was inserted through the tracheal opening to guide withdrawal of the endotracheal tube to the level of the vocal cords; and (4) size 8 tracheostomy cannulas were inserted over 28F dilators. The average time from skin incision to insertion of the tracheostomy tube was 12 minutes (< 10 minutes, 41 patients; 10 to 15 minutes, 37 patients; > 15 minutes, 22 patients). Sixty-five percent had unfavorable anatomic conditions due to spinal precautions or diffuse neck edema. Postoperative complications occurred in four patients; surgical emphysema after tracheal lacerations in three, cannula dislodgment in one. All complications were successfully managed without an operation by tube exchange (n = 3) or observation (n = 1); there was no procedure-related mortality. Forty patients were available for long-term follow-up (6-18 months after tracheostomy) by telephone; one had persistent hoarseness without respiratory difficulty. We concluded that bedside PDT is safe and easy to teach when performed with a technique that ensures correct instrumentation.

External laryngeal trauma is rare, accounting for less than 1% of all trauma cases seen at major centers. We report the case of a man who experienced multiple injuries, including an external laryngeal trauma. The primary signs and symptoms of his laryngeal trauma were hoarseness, hemoptysis, the loss of his laryngeal prominence (Adam's apple), neck tenderness, traumatic emphysema in the neck, and a small penetrating wound to the right of the laryngeal prominence. The patient underwent immediate tracheostomy and surgical exploration. On long-term followup, his voice quality and airway patency improved. This case illustrates the importance of rapid identification and early management of laryngotracheal trauma in a patient with multiple injuries.

During 8-year period 14 patients were treated for laryngotracheal trauma complex (8 of them with blunt injury and 6 with penetrating injury). The most common signs and symptoms were respiratory distress in 85.6%(12 patients), subcutaneous emphysema in 85.6% (12 patients) hoarseness or dysphonia in 64.3%(9 patients) and hemoptysis in 64.3% (9 patients). Tracheostomy was preferred for airway control and was required in 100% of the patients. Laryngotracheal plasty in 9 patients (6 patients within 6-48 hour after injury, 3 patients in 3-8 day after injury). Long-term airway quality was measured in 11 patients (for 2-4 year follow-up): A grade in 5 patients, B in 4 patients, and C in 2 patients.

A retrospective study of 35 patients with acute external laryngeal injury who were treated at Maharaj Nakorn Chiang Mai Hospital from January 1989 to 1998 was done. Eighty-six per cent of the patients with blunt trauma had been injured from a motor vehicle accident and the rest had a penetrating injury from a stab wound. The frequent signs and symptoms were hoarseness, skin contusion, pain and subcutaneous emphysema. The severity of the injury was classified into minor and major groups. There were 2 patients in the minor group and 33 in the major group. Both patients in the minor injury group had good result from conservative treatment. All patients in the major injury group, except one with left vocal cord paralysis, required surgical management. No airway problem was found in any patient and only one patient had unintelligible voice after treatment. Twenty-three per cent had minor complications and responded well to conventional treatment. Early diagnosis and proper management gave the best outcome of the patient's airway and voice.

Traumatic airway injuries are rare in children, partly due to their unique anatomy. The larynx is well protected from direct blows behind the mandibular arch, and only a small portion of the trachea is unprotected above the manubrium due to the relatively short neck. Furthermore, the tracheobronchial tree is less prone to injuries as compared with adults due to its elasticity. A high index of suspicion is thus needed to adequately diagnose and manage pediatric airway injuries. Laryngotracheal injuries in particular may present with discreet initial symptoms that if undiagnosed may rapidly progress to loss of airway. The most important signs of laryngeal injury include hoarseness and subcutaneous emphysema. Tracheobronchial injuries often present with dramatic symptoms, the most common being pneumothorax, which does not resolve after placement of chest tube, or large persistent air leaks. Endoscopy is mandatory on suspicion of injury to the larynx, trachea, or bronchi. CT scan may be helpful in determining the extent of injury to the larynx. Correct management of the airway in laryngotracheal injuries has a direct impact on morbidity and mortality. Endotracheal intubation over a flexible bronchoscope during spontaneous ventilation and in halothane anesthesia is the method of choice in children, but it should be performed in the operating room with the possibility of emergency tracheotomy. Cricothyroidotomy should be avoided in all laryngotracheal injuries because this method may aggravate the injury. Most laryngotracheal injuries in children can be conservatively managed. Extensive injuries, including displaced fractures of the cartilage, injuries to the recurrent nerves, and laryngotracheal separation, require surgical intervention. Injuries to bronchi and the thoracic trachea that do not cause a persistent air leak, and where the lungs expand completely after insertion of chest tubes, may be managed conservatively. All other injuries to the tracheobronchial tree should be repaired surgically as soon as feasible. Induction of anesthesia and opening of the chest may make ventilation difficult and are best managed by selective intubation of the contralateral lung. Long-term outcome after laryngeal, tracheal, and bronchial injuries in children, if managed swiftly and accurately, is usually excellent unless other injuries are present. The final result is improved by early recognition and early surgical intervention. These children need to be followed endoscopically for months and sometimes years in order to diagnose and treat stenoses as soon as they occur. Long-term pulmonary function has been shown to be excellent. Children with bilateral recurrent nerve paralysis may not fully recover voice or airway.

Congenital lobar emphysema (CLE) is characterized by overdistension and air-trapping in the affected lobe, and is one of the causes of infantile respiratory distress. In this report, we review our 27 years of experience with 30 CLE patients. Patients' medical records were evaluated with regard to age, clinical presentation, diagnostic methods, associated diseases, treatment, histopathologic findings, and final clinical and laboratory findings at the end of a long-term period. The mean age of 30 patients (18 male) at diagnosis was 4.9 +/- 6.7 months (range, 2 days-2.5 years). Tachypnea, dyspnea, cough, cyanosis, wheezing, hoarseness, and decreased breath sounds on the affected side were the main symptoms and clinical findings. On chest X-rays, emphysema was seen in all patients; shift/herniation to the opposite lung, atelectasis, and pneumothorax were observed in 16, 5, and 2 cases, respectively. Computerized tomography of the thorax was performed in 16 cases and revealed emphysema at affected lobe/lobes in all, a shift/herniation to the opposite side in 12 cases, and atelectasis of neighbor lobe/lobes in 7 cases. All 8 patients who had perfusion scintigraphy showed reduced perfusion in the affected lobe. Narrowed and flaccid bronchi were detected in one patient by using flexible bronchoscopy. Blood gas analysis was performed in 11 patients, and hypoxia and hypercarbia were revealed in 9 and 7 of these patients, respectively. The most common affected lobe was the left upper lobe (57%), followed by the right upper lobe (30%) and right middle lobe (27%). Two lobes were involved in 4 patients. Associated abnormalities were observed in 5 patients. Twenty-one patients underwent lobectomy; 9 were followed conservatively. Ages at diagnosis were significantly younger in surgically treated patients. Emphysema was detected in all pathological specimens, with an additional bronchial cartilage deficiency in 2 patients. In the surgically treated group, 2 patients died and 2 patients were lost to follow-up. In the conservatively treated group, one patient was lost to follow-up. Mean follow-up duration of all patients was 63.2 +/- 56.2 months (range, 1-209 months). At follow-up visits, all patients were doing well. In surgically treated patients, chest X-rays were normal (9 cases), or showed hyperlucency on the operated side (6 cases) or chronic changes in the operation area (2 cases). Hyperexpansion in the affected lobe was found to be reduced in all cases in the conservatively treated group.

In Canada, endoscopic resection using a CO(2) laser has been generally ignored as a treatment option. In this article, we present an introductory analysis of our clinical experience with the CO(2) laser at the QEII Health Sciences Centre in Halifax, Nova Scotia. Outcomes from a cohort of 36 patients with glottic cancer staged as Cis-T2 (7 Cis, 17 T1, 12 T2) who underwent endoscopic resection using a CO(2) laser between January 2002 and June 2005 were studied retrospectively. The mean follow-up was 16.2 months (range 0-41 months). At the time of the study, no patient had died of laryngeal disease, one patient had died of another disease, and one patient was lost to follow-up. There had been three recurrences in the cohort: two local recurrences and one recurrence in a regional lymph node. After salvage, all patients with recurrences were disease free at the time of the study. There were three postoperative complications in the cohort: one postoperative myocardial infarction, one case of respiratory distress postextubation, and one case of subcutaneous emphysema. The average time for the procedure was 0.97 hours (range 0.25-2.75 hours). The average postoperative length of stay was 1.2 days (range 0-12 days). Of 35 cases with follow-up, 60% had no reported problems with voice in their last visit and 11% reported consistent hoarseness or weakness. Although our oncologic results do require more follow-up, based on our positive experience thus far, we believe that endoscopic management of glottic cancer is a treatment option that may be underused in the Canadian health care system.

A previously healthy 16-year-old boy presented to the Emergency Department with a 2-day history of hoarseness, sore throat, and chest tightness. The physical examination was significant for diffuse neck and chest subcutaneous emphysema. A computed tomography (CT) scan of the neck and chest revealed pneumomediastinum after a plain chest X-ray study failed to uncover this finding. The patient reported that 5 days before presentation he forcefully inhaled helium gas directly from multiple party balloons in an attempt to alter his voice. The patient fully recovered over the next 2 days. Spontaneous pneumomediastinum developed in this patient with no underlying lung disease, presumably from air leakage secondary to the excessive elevation of intra-thoracic pressure due to repetitive inhalation of helium gas. Spontaneous pneumomediastinum remains largely underdiagnosed clinically, especially in young, healthy patients.

The larynx and surrounding soft tissues are vulnerable to injury during athletics despite protective equipment and rule modifications. Laryngeal injuries are uncommon but potentially fatal conditions that pose risks to the voice, airway, and esophagus of athletes who sustain blunt or penetrating neck trauma. Common symptoms and signs of laryngeal trauma include hoarseness, dyspnea, hemoptysis, dysphonia, respiratory distress, anterior neck tenderness, subcutaneous emphysema, and loss of normal laryngeal architecture. Diagnostic evaluation includes plain radiographs, computed tomography, and fibroscopic endoscopy. Most athletes with laryngeal injuries will require surgical treatment to restore normal regional anatomy and vocal quality. Less severe injuries may be treated with close observation, serial endoscopy, medications, and vocal rest.
