OBJECTIVE: To evaluate the safety and efficacy of endoscopic treatment of subglottic stenosis with flexible bronchoscopy via laryngeal mask airway (LMA) approach. METHODS: The records of all patients who underwent endoscopic surgery for subglottic stenosis (SGS) from November 2019 to January 2023 at an academic medical center were reviewed with attention to demographics, patient comorbidities, airway stenosis characteristics, operative time details, surgical complications, and post-operative course...

INTRODUCTION: Flexible bronchoscopy (FB) and bronchoalveolar lavage (BAL) are frequently performed in children with known or suspected aspiration, however, the additive value of FB in conjunction with direct laryngoscopy and rigid bronchoscopy (DLB) has not been previously quantified. This study details the common endoscopic/cytological findings and associated management impact of FB and BAL in pediatric Aerodigestive patients undergoing combined airway evaluation (FB and DLB) for oropharyngeal dysphagia...

We aimed to clarify the long-term outcomes and prognosis of vocal cord paralysis (VCP) after cardiothoracic surgery in infants as well as the usefulness of laryngeal ultrasound (LUS) as screening for VCP. Overall, 967 infants aged 1-year-old or younger who underwent cardiothoracic surgery between 2008 and 2022 were included in this study. We divided the patients into two groups based on the period on whether they underwent screening without or with LUS and compared the incidence of VCP between the groups. There were no differences in the patients' preoperative characteristics between the two periods, whereas the incidence of VCP was significantly higher in period 2 than in period 1 (11...

PURPOSE: Laryngeal surgeries using a flexible nasopharyngoscope equipped with an operative channel has gained popularity, with gradual increase in the variety of interventional office-based procedures, under local anesthesia. The purpose of this study is to analyze the tolerance of such procedures. MATERIALS AND METHODS: Retrospective cohort study. 337 cases were performed during 2 years. We collected the following data: type of pathology, type of procedure and modalities of anesthesia, adverse events...

Vascular anomalies of the head and neck frequently involve the upper aerodigestive tract and can cause some level of airway obstruction. It is important to fully evaluate the extent of a lesion and resultant functional impairment with a flexible fiberoptic laryngoscopy. Treating these lesions is difficult and considering how to manage the airway during a procedure is critical. A multidisciplinary approach should be used for airway management with alternative intubation plans established prior to induction of anesthesia...

INTRODUCTION: Obstructive sleep apnea (OSA) is highly prevalent in infants with laryngomalacia (LM). Previous studies have reported high rates of persistent OSA following supraglottoplasty (SGP). The objective of this study is to describe the findings on drug-induced sleep endoscopy (DISE) in infants with LM. METHODS: A retrospective review was performed including infants (12.5 months of age or less) with LM who underwent DISE along with direct laryngoscopy and bronchoscopy (DLB)...

The aim of our study is to analyze the efficacy of nasal septal cartilage as cap-graft in laryngo-tracheoplasty in cases of Laryngotracheal stenosis. This was a prospective observational study carried out at a tertiary care hospital from March 2020 to March 2023. Total 8 patients who underwent laryngo-tracheoplasty using nasal septal cartilage as anterior Cap-graft were included in the study. Detailed history and clinical evaluation followed by diagnostic Flexible Fiber-optic Laryngoscopy and radiological investigations were done for all patients with post operative follow up for at least 1 year...

BACKGROUND: Children with aerodigestive dysfunction often undergo triple endoscopy (flexible bronchoscopy, rigid direct laryngoscopy and bronchoscopy, and esophagogastroduodenoscopy) for diagnostic evaluation as well as screening prior to airway reconstruction. Prevalence and risk factors for eosinophilic esophagitis (EoE) in this population are poorly understood. METHODS: A retrospective chart review was performed for pediatric patients, aged 0-21 years, who received a triple endoscopy with biopsy from January 1, 2015, to December 31, 2019, at the Children's Hospital at Montefiore (CHAM)...

Tracheobronchopathia osteochondroplastica (TBPO) is a rare and benign idiopathic disease of the tracheobronchial tree, characterized by osseous, and/or cartilaginous submucosal nodules involving the anterior and lateral walls of the airways with sparing of the posterior wall. We present a case of a 51-year-old non-smoker female, presenting with a 2-year history of gradually enlarging anterior neck mass with foreign body sensation, frequent throat clearing, and occasional hoarseness. She was initially diagnosed with recurrent respiratory papillomatosis due to the presence of nodules on flexible laryngoscopy...

PURPOSE: Supraglottic compression is thought to underlie vocal effort in patients with primary muscle tension dysphonia (pMTD). However, the relationship between supraglottic compression and vocal effort in this clinical population remains unclear. Gold standard laryngoscopic assessment metrics for supraglottic compression are also lacking. The goals of this study were to identify metrics proposed in the literature that could distinguish patients diagnosed with pMTD from typical voice users and determine their relationships to the vocal effort...

BACKGROUND: Recently, tracheal narrowing has been recognized as a significant comorbid condition in patients with Morquio A, also known as mucopolysaccharidosis IVA.
