OBJECTIVES/HYPOTHESIS: Cricoid fracture is a serious concern for balloon dilatation in airway stenosis. Furthermore, there are no studies examining tracheal rupture in balloon dilatation of stenotic segments. The aim of this study was to evaluate the effect of supramaximal pressures of balloons on the cricoid and tracheal rings. STUDY DESIGN: Prospective cadaveric study. METHODS: Seven cadaveric laryngotracheal complexes of normal adults with intact cricothyroid membranes were acquired...

Genetic resistance or susceptibility to infectious diseases has been largely associated with the avian major histocompatibility complex (MHC) genes. Our goal was to determine resistance and susceptibility of MHC B haplotype in congenic and inbred chicken lines in order to establish a resistant-susceptible model. Eight congenic lines (253/B18, 254/B15, 330/B21, 312/B24, 331/B2, 335/B19, 336/B21, and 342/BO), two inbred lines (003/B17 and 077/B19), and three commercial lines (white leghorn, brown layers, and broilers) were used in two experiments...

The avian coronavirus infectious bronchitis virus (IBV) S1 subunit of the spike (S) glycoprotein mediates viral attachment to host cells and the S2 subunit is responsible for membrane fusion. Using IBV Arkansas-type (Ark) S protein histochemistry, we show that extension of S1 with the S2 ectodomain improves binding to chicken tissues. Although the S1 subunit is the major inducer of neutralizing antibodies, vaccination with S1 protein has been shown to confer inadequate protection against challenge. The demonstrated contribution of S2 ectodomain to binding to chicken tissues suggests that vaccination with the ectodomain might improve protection compared to vaccination with S1 alone...

We describe the management of posterior trachea tears after blunt neck trauma in two children. The first, a 5 year-old boy who fell off his scooter, causing a 1.0cm tear in the membranous cervical trachea, was managed conservatively with 5 days of intubation. The second, a 12 year-old girl who fell on her bicycle, causing a 4.0cm tear in the membranous thoracic trachea, was repaired with thoracoscopic techniques. The presumed mechanism may be expansion of the U-shaped cartilage with tear of the membranous trachea...

Surgical emphysema secondary to tracheal tear is a rare but serious complication after thyroidectomy. It is usually resolved by conservative management; but in case of compromised airway, early airway control and surgical intervention is required. This is the case report of a 52-year woman diagnosed as thyroid carcinoma, who developed rapidly progressive surgical emphysema involving head and upper thorax, following total thyroidectomy, in post anesthesia care unit (PACU). The complication was related to tracheal tear occurring during excision of huge thyroid mass, encroaching trachea...

Iatrogenic tracheal rupture (ITR) represents a life-threatening condition requiring prompt diagnosis, management, and treatment. The management of ITR is challenging, and treatment options depend on tear location, size, injury extent, and the patient's respiratory status. Although this complication has been extensively reported in published literature, the best evidence practice, for the management, requires clarification. In this review, the authors focused on the establishment of a differential diagnosis and the potential mechanism of the injury, the decision-making process, and the therapeutic approaches...

During bronchoscopically guided percutaneous dilatational tracheostomy, a 71-year-old woman suffered a long-stretched tear to the posterior tracheal wall. The injury was suspected to be caused by blunt trauma during dilation or cannula insertion, possibly aggravated by vigorous cuff inflation. Since the defect ended just 0.5 cm proximal to the main carina, placing a cuffed endotracheal tube beyond the injury was not an option. However, we decided for a conservative treatment approach by placing a cuffed endotracheal tube under bronchoscopic visualization in direct proximity to the cranial end of the laceration...

Endobronchial stent placement is a novel therapy for treatment of iatrogenic tracheal tears. A review of the available literature shows surgery and long-term intubation being the established treatment strategy. We describe the case of a 64-year-old woman with a tracheal rupture following endotracheal intubation for routine surgery. Pneumo-mediastinum and chest pain were the predominant symptoms. She was treated with a covered self-expandable metal stent that closed the tear and led to immediate symptom relief...

BACKGROUND: Blunt injuries to the cervical trachea remain rare but present unique and challenging clinical scenarios for prehospital providers. These injuries depend on prehospital providers either definitively securing the injured airway or bridging the patient to a treatment facility that can mobilize the necessary resources. CASE SUMMARY: The case presented here involves a clothesline injury to a pediatric patient that resulted in complete tracheal transection and partial esophageal transection...

Iatrogenic tracheal laceration is a known complication of emergent endotracheal intubation. Patients with tracheal laceration present a therapeutic challenge. There is no established standard treatment approach in this patient population. Interventions reported include conservative management, stent placement, or surgery. We present our experience of tracheal tears in patients with respiratory failure successfully managed with polyurethane-covered nitinol stent, including three cases of postintubation and one case of postsurgical tracheostomy tracheal injury...

Ideal speech restoration remains a difficult challenge for patients undergoing laryngectomy so far. Our aim was to explore the feasibility of neoglottic reconstruction with sternohyoid muscles on upper-tracheal orifice after total laryngectomy which can obtain relatively ideal voice rehabilitation. Fifteen male patients are laryngectomized, of whom eight with standard total laryngectomy and seven underwent nonstandard total laryngectomy with epiglottis conserved. After laryngectomy, the upper margin of the anterior hypopharyngeal mucosa (postcricoid mucosa) was stitched to the posterior margin of upper-tracheal orifice and a triangle-shaped neoglottis on upper-tracheal orifice was reconstructed using bilateral sternohyoid muscles near the hyoid bone which were sutured to the posterior wall and bilateral of upper-tracheal orifice...

Direct injury to airway is a rare event and also a challenge to anaesthesiologist and surgeon. We present a case report of open tracheal injury with right pneumothorax in a young male following assault with a sharp weapon. In spite of a chest tube in situ, the patient came with collapse of one lung and tachypnoea which required surgical exploration. Lower airway was evaluated by fibre-optic bronchoscopy through the open tracheal wound while he was awake and tracheal tube was passed over the bronchoscope. There was no vascular or oesophageal injury detected...

BACKGROUND: In recent years, there has been a shift in airway management with the use of cuffed endotracheal tubes (ETT) in pediatric patients. While the use of a syringe to deflate the cuff is generally recommended, anecdotal observations suggest that some healthcare practitioners tear off the pilot balloon from ETT to deflate the cuff. This study was conducted to estimate the residual volume in the cuff when the pilot balloon is torn off for deflation. METHOD: The in vitro study was conducted in three phases...

Various surgical approaches may be employed for esophageal resection. Major airway injuries due to transhiatal esophagectomy include vertical tears in the membranous trachea. Tracheal injury is an uncommon but potentially fatal complication. This article describes the technique to repair the posterior membranous tracheal tear, extended just over the carina through a transcervical-transsternal approach, thereby avoiding a second thoracotomy. Six patients with posterior membranous tracheal injury underwent this procedure...
