Article Synopsis
  • The study investigates airway management techniques and demographic data of patients with congenital tracheal stenosis (CTS) during preoperative, intraoperative, and postoperative periods, based on a review of patient charts from a pediatric medical center from 2001 to 2018.
  • Out of 148 patients analyzed, the majority had congenital tracheal rings as the cause of their CTS, with a median age of 9 months at surgery and most experiencing 50% to 80% stenosis.
  • Findings emphasize the importance of coordinated airway management between surgical and anesthesia teams during slide tracheoplasty, which is shown to be an effective treatment for CTS.

Article Synopsis
  • The study aimed to analyze the incidence and predictors of pediatric patients with tracheostomies who continue into adulthood with their tracheostomies.
  • Researchers reviewed data from 663 pediatric tracheostomy patients treated between 2009 and 2022, finding that 15.5% were alive at age 18 or older, with specific outcomes related to mortality and decannulation.
  • Key predictors for maintaining a tracheostomy into adulthood included older age at placement and severe neurocognitive disabilities, suggesting a need for specialized transition programs for these patients.

Objectives: The objective of this study is to determine the time to ventilator liberation and decannulation after tracheostomy placement in children with bronchopulmonary dysplasia (BPD) and pulmonary hypertension.

Methods: A prospective cohort study included all children (<18 years old) who underwent tracheostomy between 2015 and 2021 with or without a diagnosis of BPD. The primary outcomes were time to ventilator liberation, tracheostomy decannulation, or death with tracheostomy in place.

Objectives: Posterior glottic diastasis (PGD) is an underappreciated etiology of dysphonia in patients with prior airway reconstruction or prolonged intubation. In endoscopic posterior cricoid reduction (ePCR), cricoid is removed to minimize the posterior glottic gap. Dynamic voice computed tomography (DVCT) permits visualization of the posterior glottis, estimating the amount of cricoid to be removed.

Objectives: To determine whether long-term outcomes after pediatric tracheostomy are impacted by neighborhood socioeconomic disadvantage.

Methods: A prospective cohort of children with tracheostomies was followed at an academic pediatric hospital between 2015 and 2020. Patients were grouped into low or high socioeconomic disadvantage using their neighborhood area deprivation index (ADI).

Objective: Pediatric tracheostomy patients disproportionately experience hearing loss and are at risk for delayed identification due to their medical complexity. Nonetheless, protocols to monitor hearing in these children are lacking. This quality improvement (QI) initiative aimed to increase the rates of audiometric testing within 12 months of pediatric tracheostomy placement.

Objectives: To examine the relationship between neighborhood-level advantage and severe obstructive sleep apnea (OSA) in children.

Methods: A retrospective case-control study was conducted on 249 children who underwent adenotonsillectomy and had full-night polysomnography conducted within 6 months prior. Patients were divided into more or less socioeconomically disadvantaged groups using a validated measure, the area deprivation index (ADI).

Objectives: To determine how initial postoperative airway endoscopy findings after stent removal predict successful decannulation in children undergoing double-staged laryngotracheoplasty (dsLTP). Secondary objectives assessed timing of decannulation and number of endoscopic interventions needed after dsLTP.

Methods: A case series with chart review included children who underwent dsLTP at a tertiary children's hospital between 2008 and 2021.

Objectives: Bronchial anomalies are rare but challenging conditions to treat in children, encompassing a variety of structural abnormalities that could compromise airway patency. This includes complete rings, absent cartilage, traumatic avulsions, bronchoesophageal fistulas, and cartilaginous sleeves. The objective of this study is to describe the characteristics and outcomes of a series of pediatric cases of bronchial anomalies that were treated by slide tracheobronchoplasty.

Objective: To determine survival among critically ill children when caregivers decline tracheostomy placement.

Study Design: Retrospective cohort.

Methods: All children (<18 years) obtaining a pre-tracheostomy consultation at a tertiary children's hospital between 2016 and 2021 were included.

Importance: The American Academy of Otolaryngology-Head and Neck Surgery Foundation has recommended yearly surgeon self-monitoring of posttonsillectomy bleeding rates. However, the predicted distribution of rates to guide this monitoring remain unexplored.

Objective: To use a national cohort of children to estimate the probability of bleeding after pediatric tonsillectomy to guide surgeons in self-monitoring of this event.

The objective of this work is to examine the feasibility of revision endoscopic posterior costal cartilage graft (EPCCG) placement for posterior glottic stenosis (PGS) and bilateral vocal fold immobility (BVFI). Revision and primary cases were compared with respect to decannulation rates, and it was hypothesized that there would be no difference in outcomes. Twenty-one patients met inclusion criteria (14 primary, 7 revision).

Objective: To determine the impact of a child with a tracheostomy on caregiver quality of life.

Methods: A repeated cross-sectional analysis included families with tracheostomy-dependent children between 2019 and 2021. Caregivers were surveyed using the PedsQL™ Family Impact Module with assessments at tracheostomy placement and during ambulatory office visits.

Advances in neonatal and pediatric critical care have resulted in a growing population of medically complex children with a tracheostomy. These children are vulnerable to adverse events from underlying comorbidities, risks of tracheostomy, equipment malfunction, and caregiver inexperience. Multidisciplinary tracheostomy teams have emerged as effective initiatives to address these patient safety concerns.

Objectives: To determine the rate of surgical site infections (SSI) after pediatric open airway reconstruction using a nationwide database.

Study Design: Cross-sectional study of the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-P) Database.

Methods: The ACS NSQIP-P was queried for open airway surgeries between 2013 and 2019 determining postoperative SSI and wound dehiscence with a random sample of non-airway cases serving as a control group.
