Idiopathic progressive subglottic stenosis is a rare cause of tracheal narrowing. Partial cricotracheal resection and anastomosis can cure idiopathic stenosis, even if some patients may require multiple interventions and experience voice and swallowing deterioration. We investigated risk factors for retreatment and assessed the impact of crico-tracheal resection on functional parameters. We conducted a retrospective multicentric study on 44 female patients (mean age 52.6 ± 13.1 years) affected by idiopathic stenosis and treated by crico-tracheal resection between 2002 and 2016...

Objective: To investigate the effect of different cryoablation time on tracheal traumatic granulation formation and its mechanism. Methods: A total of 32 rabbits were randomly assigned into four groups (A-D). Group A underwent tracheotomy alone. Group B, C and D received intra-tracheal brush rubbing to establish airway granulation model. Group C and D underwent 30 s and 2-minute cryoablation respectively. Tracheal specimens of all groups were collected to examine pathological changes using HE staining. Levels of transforming growth factor beta 1 (TGF-β(1)) and CD34 in tracheal granulation were evaluated using immunohistochemistry (IHC) and real-time quantitative reverse transcription polymerase chain reaction (RT-qCR)...

Postintubation tracheal stenosis (PITS) is an iatrogenic complication seen increasingly often as the number of intensive care unit (ICU) bed multiply, the indications for endotracheal intubation expand and disease awareness rises. PITS has a clinical severity spectrum ranging from asymptomatic cases to patients requiring urgent interventional procedures. It should therefore always be considered in the differential diagnosis in patients with a history of intubation who present with the complaint of difficult breathing...

Tracheostomy is a common procedure for long-term airway management. Although the overall complication rate is greater than 50%, the incidence of serious complications is low. These serious complications can, however, lead to significant morbidity and mortality and it is incumbent on the emergency provider to be prepared to deal with such tracheostomy-related emergencies. The greatest life threats to the tracheostomy patient are decannulation, obstruction, and hemorrhage. Other important but lower-acuity complications include tracheoesophageal fistula formation, tracheal stenosis, infection, and tracheocutaneous fistula formation...

The purpose of this study was to evaluate whether the prior implantation of a 3D-printed polycaprolactone (PCL) artificial trachea in the omentum is beneficial for revascularization of the scaffold and reduces associated complications in the reconstruction of a circumferential tracheal defect. Ten New Zealand rabbits were divided into 2 groups: (1) PCL-OC group (PCL scaffold cultured in omentum for 2 weeks before transplantation) and (2) PCL group. In the PCL-OC group, newly formed connective tissue completely covered the luminal surface of the scaffold with mild inflammation at 2 weeks postoperatively; a minor degree of stenosis was noted at 8 weeks postoperatively...

Idiopathic subglottic stenosis (ISS) is defined as the narrowing of the upper airway without any known cause. A 40-year-old female was referred to our hospital with the complaint of exacerbation of dyspnea causing difficulty in going out. Chest computed tomography (CT) scan and bronchoscopy revealed subglottic tracheal stenosis with a luminal diameter of 5 mm at the narrowest part. Tracheal mucosa of the stenotic lesion was smooth, and the patient had no previous medical history. Subglottic tracheal resection of the stenotic lesion and reconstruction were performed...

Transcatheter aortic valve replacement (TAVR) is an alternative to traditional surgery in patients considered to be at high or intermediate risk for open surgical repair of aortic stenosis. Despite its overall safety and efficacy, TAVR is associated with potentially serious complications including major vascular injury. Tracheal compression resulting from vascular pathology has been previously reported; however, airway compromise secondary to vascular injury during TAVR has not been described. We report a case of airway compression and respiratory compromise resulting from injury to the right subclavian artery during TAVR...

The aim of this study was to evaluate a novel composite material for tracheal reconstruction in an ovine model. A polymer containing various forms of carbon fibers (roving, woven, and nonwoven fabric) impregnated with polysulfone (PSU) was used to create cylindrical tracheal implants, 3 cm in length and 2.5 cm in diameter. Each implant, reinforced with five rings made of PSU-impregnated carbon-fiber roving, had three external layers made of carbon-fiber woven fabric and the inner layer formed of carbon-fiber nonwoven fabric...

Tracheal stenosis may occur secondary to trauma, tumors, infections, and inflammatory and iatrogenic diseases. Patients with tracheal stenosis must be evaluated carefully and require comprehensive preoperative examination, including pulmonary function tests and radiographic studies. Two male patients (one 18 years of age and the other 46 years of age) with tracheal stenosis were scheduled for tracheal resection and reconstruction. They were given different modes of anesthesia (with and without intubation). Fiberoptic intubation was selected in the 18-year patient, and non-intubation was selected in 46-year patient...

In suspension microlaryngoscopy, the endotracheal tube, which hampers the vision of the subglottic plane, may disturb the surgery. Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) provides effective aventilatory mass flow under deep sedation and seems an interesting approach to operate without endotracheal tube. The objective is to evaluate the indications, the technique and the failures of THRIVE in laryngeal surgery. This prospective study included 19 patients over the age of 18, that overwent laryngeal surgery under laryngosuspension...

A 16-month old female was referred to our practice for laryngotracheal reconstruction (LTR) for acquired subglottic stenosis (SGS) diagnosed at 4 weeks of age due to prolonged intubation. She has a history of open thoracic repair of congenital tracheoesophageal fistula that was complicated by a pneumothorax and phrenic nerve paralysis. We performed a variation of an anterior and posterior cricoid split LTR with tracheal stenting in order to avoid risks of pulmonary morbidity from costochondral cartilage harvesting...
