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...

A 59-year-old man presented to the emergency department with a chief complaint of sore throat after swallowing sodium picosulfate/magnesium citrate powder for bowel preparation, without first dissolving it in water. The initial evaluation showed significant mucosal injury involving the oral cavity, pharynx, and epiglottis. Endotracheal intubation was performed for airway protection in the emergency department, because the mucosal swelling resulted in upper airway compromise. After conservative treatment in the intensive care unit, he underwent tracheostomy because stenosis of the supraglottic and subglottic areas was not relieved...

IMPORTANCE: The etiology of recurrent croup is often anatomic. Currently there is no set criteria for determining who should undergo diagnostic bronchoscopy and which patients are at most risk for having a clinically significant finding. Few studies have addressed these questions. OBJECTIVE: To identify risk factors for clinically significant findings on bronchoscopy in children with recurrent croup and the frequency of bronchoscopy findings in general. DATA SOURCES: PUBMED, Ovid MEDLINE, EMBASE...

It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis. Airflow velocity changes at the anterior midline of the vocal folds were synchronized with subglottal pressure changes during each phonation cycle...

OBJECTIVES: Awake Flexible Tracheobronchoscopy (FTB) is an alternative to rigid bronchoscopy or sedated flexible bronchoscopy and allows an awake examination of the tracheobronchial tree. We hypothesized that the ability to perform office bronchoscopy as the need arises during a clinic visit would lead to a high rate of previously undiagnosed and clinically relevant findings. This study reports the rate and nature of such findings for this procedure at our institution. STUDY DESIGN: Retrospective chart review...

Procedure of intubation of children is different to intubation in adults and requires specific considerations. Before intubation management of difficult airway problems should be anticipated. Risk of developing hypoxia is common in children usually due to a reduced apnea tolerance and demands skill of the medical team. Due to soft tissues of the upper airways and the V-shaped epiglottis several laryngoscopes are available. Attention should be kept on a physiological subglottic stenosis, which determines the size of the endotracheal tube...

Idiopathic subglottic stenosis is a disease characterized by slow, progressive scarring and constriction of the subglottic airway. It almost always occurs in females between the 3rd and 5th decade of life. Symptoms are frequently misinterpreted as asthma and patients are referred for endoscopic evaluation only when asthma medications fail to alleviate their symptoms. Treatment options can be divided into endoscopic and open surgical techniques. Microlaryngoscopic scar reduction by laser followed by balloon dilation usually delivers good short-term results...

Recurrent tracheoesophageal fistula (TEF) is still difficult to diagnose and repair. In almost all cases, recurrence appears relatively soon after the primary surgery. We herein describe a case of recurrent TEF that appeared 10 years after the primary repair. At 2 years of age, the patient suffered from mental retardation due to encephalitis and developed a hiatus hernia with gastro-esophageal reflux. He underwent the repair of a hiatus hernia and fundoplication at 3 years of age. However, the hiatus hernia recurred 6 months after the operation...

OBJECTIVE: To determine if the results of routine spirometry and flow volume loops (Pulmonary Function Tests (PFTs)) can be used to distinguish Paradoxic Vocal Fold Movement Disorder (PVFMD) from Subglottic Stenosis (SGS). METHODS: PFT records and medical history of 49 patients with diagnosis of PVFMD and 39 patients with SGS were compared. Groups were then subdivided to compare PFTs in patients with and without smoking history or lung disease. RESULTS: Peak expiratory flow rate (PEFR) and Expiratory Disproportion Index (ratio of forced expiratory volume in 1 second (FEV1) over PEFR (FEV1/PEFR)) were both significantly different between patients with SGS and those with PVFMD (p<0...
