We have developed the algorithm for the choice of the surgical strategy for the treatment of chronic post-traumatic laryngeal stenosis with the purpose of enhancing the effectiveness of the management of the patients presenting with this condition. The proposed approach envisages obtaining anthropometric characteristics of the patients, determination of the type of his (her) neck and constitution, construction of the regressive models of the clinically significant laryngometric parameters based on the results of the clinical observations including the dimensions of the glottal fissure and the position of the vocal folds, calculations of the size of the autotransplant and the length of the T-shaped tube based on the results of the mathematical analysis of the anthropo- and organometric characteristics of the concrete patient, the laryngoplastic and prosthetic treatment of the newly formed laryngo-tracheal passage...

Cut throat injuries are one of the emergency conditions managed by ENT specialists. If not treated in time, they may lead to death. Prevention of these complications depends on immediate resuscitation by securing the airway by tracheostomy or intubation, prompt control of hemorrhage and blood replacement. The present study was conducted to study the sociodemographic profile of patients of cut throat injury, motives behind cut throat injury, site and depth of the injury, treatment given at our hospital and outcome...

INTRODUCTION: The segmentation and skeletonisation of images via computed tomography (CT) airway lumen volumetry provide a new perspective regarding the incorporation of this technique in medical practice. Our aim was to quantify morphological changes in the large airways of patients with acromegaly through CT and, secondarily, to correlate these findings with hormone levels and pulmonary function testing (PFT) parameters. METHODS: This was a cross-sectional study in which 28 non-smoker patients with acromegaly and 15 control subjects underwent CT analysis of airway lumen volumetry with subsequent image segmentation and skeletonisation...

Tracheobronchial tuberculosis (TBTB) is reported in approximately 10% to 39% of the patients with pulmonary tuberculosis. It is defined as the tubercle infection of the trachea and or bronchi. Due to its non-specific presentation, insidious onset and normal chest radiography in about 10-20% of the patients, the diagnosis is delayed. Bronchoscopy is the most definite method of diagnosis which provides adequate specimens for microbiological and histopathological diagnosis. Tracheobronchial stenosis is one of the most common long term complications of TBTB resulting in significant morbidity...

A 62-year-old woman visited our hospital because of dysphagia. She was diagnosed with upper-middle esophageal type 4 cancer, which was 9 cm in length, according to the results of endoscopy. Squamous cell carcinoma was demonstrated using endoscopic biopsy. A CT scan revealed that the tumor had directly invaded into the trachea(cT4). Chemoradiotherapy(CRT) (5-FU and CDDP with 50 Gy of radiation)was administered. Although CT after CRT resulted in shrinkage of the tumor and no further tracheal invasion, esophageal stenosis remained...

Kosaku Maeda
Pediatric airway surgery is a challenging field in pediatric surgery. Laryngotracheal stenosis has a variety of congenital and acquired conditions that require precise assessment and tailored treatment for each individual patient. About 90% of acquired conditions are represented by subglottic stenosis (SGS) resulting as a complication of tracheal intubation. Congenital tracheal stenosis (CTS) is a rare and life-threatening malformation, usually associated with complete tracheal rings along a variable length of the trachea...

Zehra Hatipoglu, Mediha Turktan, Alper Avci
The trachea and bronchus surgery is generally performed due to stenosis, traumatic injury, foreign body and tumors. Preoperative evaluation and anesthesia management are very important issues because of higher mortality and morbidity rates. Patients may be asymptomatic, but airway difficulties, hypoxia, stridor, cough, hemoptysis are common conditions in these patient population. The collaboration between the surgeon and the anesthesiologist is very substantial and necessary. Anesthetic techniques include various applications such as one lung ventilation, fiberoptic intubation, jet ventilation, and apneic oxygenation, general anesthesia with or without neuromuscular blockade...

Benign tracheal stenosis is situation that occurs usually after stress is applied to a certain area in the trachea during the intubation of a patient or inflammation caused during an infection. In the current case report we will present a 65-year-old man with a benign tracheal stenosis due to a 15-day intubation with a high pressure and low volume intubation tube. Current methodology was applied in his case with an excellent result with a 1-year follow up. Cryotherapy, electrocautery-knife, balloon dilation and semi-rigid bronchoscopic technique were applied...

BACKGROUND: Reconstruction of long-segment tracheal defects can be challenging and a suitable tracheal substitute remains lacking. We sought to create a bioengineered tracheal graft to repair such lesions using acellullar bovine dermis extracellular matrix (ECM) and male human mesenchymal stem cells (hMSCs) and implant it in a porcine model. METHODS: hMSCs were seeded on the ECM and incubated for 1 week with chondrogenic factors. An anterior 4 cm × 3 cm defect was surgically created in the trachea of 4-week-old female Yorkshire pigs...

Surgery is the preferred treatment modality for benign tracheal stenosis. Interventional bronchoscopy is used as a bridge to surgery or in instances when surgery is not feasible or has failed. Stenosis in the subglottic trachea is particularly a treatment challenge, in view of its proximity to the vocal cords. Herein, we describe a patient with complete tracheal stenosis in the subglottic region, which developed after prolonged intubation and mechanical ventilation. The patient developed recurrent stenosis despite multiple surgical and endoscopic procedures...

CONCLUSION: Tight fixation of the artificial trachea is important for epithelialization and tracheal stenosis. OBJECTIVE: The authors have developed an artificial trachea and have used it for tracheal reconstruction. Although various studies on tracheal reconstruction have been conducted, no studies have examined the effect of artificial tracheal fixation on tracheal stenosis and regeneration. Therefore, the purpose of the present study was to evaluate the effect of artificial tracheal fixation...

Congenital lung agenesis is an extremely rare condition with an estimated prevalence of 34 in 1,000,000 live births. It is often associated with other congenital malformations of the skeletal, cardiovascular, urogenital, and gastrointestinal systems. We discuss the case of a 5-month-old who presented with increasing stridor over 1 month. Imaging revealed right lung agenesis, complete dextromalposition of heart, and compression of distal trachea. An intrathoracic saline tissue expander was placed which marked improved distal tracheal stenosis...

BACKGROUND: Bare metal stents may cause complications like fibrous encapsulation, granulation and tracheal stenosis. We investigated the behaviour of three commercially available stents in vivo (rabbits) and in vitro (coculture of those stents with epithelial and fibroblast cell lines). Also, we investigated whether development of tracheal stenosis could be predicted by any biological marker. MATERIALS AND METHODS: The tracheae of 30 rabbits were implanted with either nitinol stents, with or without paclitaxel elution, or a cobalt-based stent...

One of the major problems in end-stage bronchotracheal cancer is stenosis of the upper airways, either due to luminal ingrowth of the tumor or mucus plugging. Airway stents that suppress tumor ingrowth and sustain mucociliary transport can alleviate these problems in end-stage bronchial cancer. We evaluated different types of polymeric covers for a tissue engineered airway stent. The distinguishing feature of this stent concept is that respiratory epithelial cells can grow on the luminal surface of the stent which facilitates mucociliary clearance...
