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...

INTRODUCTION: Individuals with idiopathic subglottic stenosis (SGS) are at risk for voice disorders prior to and following surgical management. This study examined the nature and severity of voice disorders in patients with SGS before and after a revised cricotracheal resection (CTR) procedure designed to minimize adverse effects on voice function. METHOD: Eleven women with idiopathic SGS provided presurgical and postsurgical audio recordings. Voice Handicap Index (VHI) scores were also collected...

The respiratory system is a central part of voice production, but for phonation neither the underlying functional relations between diaphragm (DPH) and rib cage (RC), nor differences to normal breathing are yet understood. This study aims to compare respiratory dynamics in phonation and breathing via dynamic MRI of the lung. Images of the breathing apparatus of 6 professional singers were captured in a 1.5T MRI system in supine position during vital capacity breathing and maximal long sustained phonation at 3 different pitches and loudness conditions...

We describe a case where a patient presented with acute angiotensin-converting enzyme inhibitor (ACE-I) induced angioedema without signs or symptoms of upper airway edema beyond lip swelling. Point-of-care ultrasound (POCUS) was used as an initial diagnostic test and identified left-sided subglottic upper airway edema that was immediately confirmed with indirect fiberoptic laryngoscopy. ACE-I induced angioedema and the historical use of ultrasound in evaluation of the upper airway is briefly discussed. To our knowledge, POCUS has not been used to identify acute upper airway edema in the emergency setting...

A parametric study was conducted using the numerical technique that coupled a three-dimensional continuum vocal fold model with a one-dimensional Bernoulli flow model to investigate the effect of vocal fold vertical stiffness variation on voice production. Vertical stiffness gradient was defined as the ratio of the inferior-superior stiffness difference to the mean stiffness and was introduced in the cover layer. The results showed that increasing the vertical stiffness gradient would increase the peak flow rate and sound intensity and decrease the open quotient and threshold pressure...

Localized tracheobronchial amyloidosis is a rare disease that results from submucosal deposition of insoluble amyloid proteins in the large airways. Amyloidosis affecting the larynx and subglottic space typically results in unilateral, nodular vocal cord infiltration. It rarely can present with bilateral vocal cord involvement and can progress to lifethreatening respiratory failure due to upper airway obstruction. In these patients, typical treatment modalities such as CO2 laser ablation are often ineffectual...

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...

We examined the impact of expiratory muscle strength training on maximum expiratory pressure, cough spirometry, and disease progression in a 71-year-old male with amyotrophic lateral sclerosis. Maximum expiratory pressure declined 9% over an 8-week sham training period, but subsequently improved by 102% following 8 weeks of expiratory muscle strength training. Improvements in cough spirometry and mitigated disease progression were also observed post expiratory muscle strength training. Improvements in maximum expiratory pressures were maintained 6 months following expiratory muscle strength training and were 79% higher than baseline data obtained 301 days prior...

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...
