Abstract Corticosteroid-eluting endotracheal tubes (ETTs) were developed and employed in a swine laryngotracheal injury model to maintain airway patency provide localized drug delivery inhibit fibrotic scarring. Polycaprolactone (PCL) fibers with or without dexamethasone electrospun onto the ETT surface PCL-only coated ETTs placed native airways of 18 Yorkshire swine. Regular dexamethasone-PCL another injured by inner laryngeal mucosal abrasion. All groups evaluated after 3, 7 14 days (n =...
Importance Airway stenosis is a rare but debilitating disorder that significantly degrades the quality of life in affected patients. Treatments are primarily surgical, and disease management lacks established medical therapies. The North American Collaborative held its third symposium at Johns Hopkins Hospital Baltimore, Maryland, on April 15, 2024, focused strategies to advance care these proceedings summarize discussion trial design airway resulting consensus regarding clinical end points...
Inhalation injuries, caused by exposure to extreme heat and chemical irritants, lead complications with speaking, swallowing, breathing. This study investigates the effects of thermal injury endotracheal tube (ETT) placement on airway microbiome inflammatory response. A secondary aim is assess impact localized dexamethasone delivery via a drug-eluting ETT reduce laryngeal scarring. was developed in swine administering heated air (150°C-160°C) under endoscopic visualization. Following injury,...
This study investigates a novel light-activated implant system designed for injectable, dose-controlled, sustained drug delivery. The was developed by incorporating drug-releasing liposomes into biodegradable polymeric capsule. release kinetics from the at 0, 1, and 2 min of light activation were determined in vitro using tissue mimic with varying depths. A pulsed near-infrared laser 1064 nm, connected to an optical fiber, used as source. dexamethasone sodium phosphate (DSP) tunable...
Background: The term ‘laryngopharyngeal reflux’ (‘LPR’) is frequently applied to aerodigestive symptoms despite lack of objective reflux evidence. This initiative aimed develop a modern care paradigm for LPR supported by otolaryngology and gastroenterology disciplines. Methods: A 28-member international inter-disciplinary working group developed practical statements within the following domains: definition/terminology, initial diagnostic evaluation, monitoring, therapeutic trials, behavioral...
Abstract Upper airway stenosis is a potentially life-threatening condition involving the narrowing of airway. In more severe cases, may be accompanied by stridor, type disordered breathing caused turbulent airflow. Patients with have higher risk failure and additional precautions must taken before medical interventions like intubation. However, stridor are often misdiagnosed as other respiratory conditions asthma/wheezing, worsening outcomes. This report presents unified dataset containing...
Endotracheal Tubes (ETTs) maintain and secure a patent airway; however, prolonged intubation often results in unintended injury to the mucosal epithelium inflammatory sequelae which complicate recovery. ETT design materials used have yet adapt address associated complications. In this study, composite coating of electrospun polycaprolactone (PCL) fibers embedded four-arm polyethylene glycol acrylate matrix (4APEGA) is developed transform from mechanical device dual-purpose capable delivering...
Three laryngeal models were used to investigate the aerodynamic and elastic properties of vocal fold vibration: cadaveric human, excised canine, synthetic silicone folds. The aim was compare characteristics these enhance our understanding phonatory mechanisms. Flow medial glottal wall geometry acquired via particle image velocimetry. Elastic assessed from force-displacement tests. Relatively, human larynges had higher fundamental frequency values, while canine exhibited greater flow rates....
Ulnar head arthroplasty has been an emerging alternative for salvage of resection at the distal radioulnar joint (DRUJ) since early 1990s. Recently, it offered initially treating painful arthrosis or instability DRUJ. This follow-up study reports a surgeon's experience DRUJ disorders with ulnar arthroplasty. Twenty-two wrists in 20 patients (11 females, 9 males), 6 no prior wrist procedures were treated between 1995 and 2006 either Herbert-Martin (Martin Medizin-Technik, Tuttingen, Germany)...
Hospital readmissions are an important metric of quality and safety. This study seeks to characterize the relationship between obstructive sleep apnea (OSA). A better understanding this could be utilized develop preventative measures reduce readmission rates.A retrospective review patients discharged over a 24-month period Department Defense hospital was conducted. Medical records provided demographic data, presence OSA comorbid diseases, whether occurred within 30 days discharge....
This study employs validated cough assessment tools to prospectively determine the impact of tramadol on severity and quality life in subjects with neurogenic cough. The was a prospective case series planned data collection at tertiary care academic medical center laryngology practice. Sixteen consecutive collected completed pre- posttreatment tools, index (CSI) Leicester Cough Questionnaire (LCQ). All reported least some improvement their symptoms. In Wilcoxon signed rank test that compared...
Objectives/Hypothesis Quantification of clinical outcomes after vocal fold (VF) interventions is challenging with current technology. High‐speed digital imaging and optical coherence tomography (OCT) excised larynges assess intact laryngeal function, but do not provide critical biomechanical information. We developed a protocol to quantify tissue properties in intact, VFs using dynamic nanomechanical analysis (nano‐DMA) obtain precise the micrometer scale. Study Design Experimental animal...
Abstract Objective This study aimed to investigate the impact of implant’s vertical location during Type 1 Thyroplasty (T1T) on acoustics and glottal aerodynamics using excised canine larynx model, providing insights into optimal technique for treating unilateral vocal fold paralysis (UVFP). Methods Measurements were conducted in six larynges Silastic implants. Two implant locations, infraglottal, tested each at low high subglottal pressure levels. Acoustic intraglottal flow velocity field...
Purpose: The aim of this study was to explore the gap between need for gender-affirming voice and communication services (GAVCS) insurance coverage within one state. Method: An electronic, cross-sectional survey transgender/gender-diverse (TGD) adults assessed incidence cost barriers GAVCS. Then, policies from 22 major insurers were reviewed using a web-based search telephone inquiries. Finally, tool developed clinicians share available GAVCS by insurer. Results: Over half (53%) 115...
A preponderance of literature supports the safety office-based flexible endoscopic procedures upper aerodigestive tract; however, until recently there were no data regarding hemodynamic stability during these procedures. recent study showed intraprocedure changes in patients' parameters, raising concern that perhaps patients should be monitored The aim our was to determine whether physiologically significant alterations vital signs occur procedures.We performed a retrospective review 100...
Objectives/Hypothesis To describe the distribution of recurrent respiratory papillomatosis (RRP) lesions across 21 laryngeal anatomic regions in previously untreated patients at initial presentation to provide insight regarding natural history RRP. Study Design Multi‐institutional, retrospective case series. Methods Initial laryngoscopic examination videos 83 with adult‐onset RRP were reviewed. Papilloma locations recorded using a 21‐region schematic. Multivariate analyses by subsite...
