Objective: This study aims to determine the percentage of infants with neonatal intensive care unit (NICU) stay >5 days and passed newborn hearing screening (NBHS) who complete recommended audiology follow-up and who have sensorineural hearing loss (SNHL) detected on rescreen by 9 months of age.

Methods: A chart review was conducted of patients at a tertiary children's hospital born July 2020 to August 2023. Patients with NICU stay >5 days and completed NBHS were included (n = 929).

Background: Sternal wounds following cardiothoracic surgery are a challenging surgical problem, and pectoralis muscle flaps are a mainstay for reconstruction. Multiple variations of this strategy exist, and this study seeks to characterize key decision factors and patient outcomes to increase accessibility of this technique to surgeons.

Materials And Methods: This is a retrospective cohort study of adult sternal wound patients at a tertiary referral center between 2010-2020.

Facial reanimation surgery using a free functional gracilis muscle transfer is the standard of care in long-standing facial paralysis. Surgical revision rates are high, with most directed toward flap debulking and improving contour. During the index surgery, the muscle can be thinned extensively to potentially avoid revisions, but there is concern for injuring the neurovascular pedicle or weakening contractility.

Background: Our purpose was to determine if non-opioid pain control is safe and effective in the treatment of pain following intracapsular adenotonsillectomy (T&A).

Methods: A randomized, open-label, controlled trial of children ages 3-17 undergoing intracapsular T&A was conducted at a tertiary children's hospital April 2021-May 2023. Exclusions were concomitant procedures, Down syndrome, coagulopathy, craniofacial anomalies, and current opioid use.

Objective: Preserving residual hearing following cochlear implantation (CI) improves outcomes and allows patients to use electrical and acoustic stimulation. Hearing preservation and minimizing intracochlear trauma during implantation have become key areas of research and device development in recent years. This meta-analysis evaluated whether patient characteristics or surgical methodology impact hearing preservation postpediatric CI.

Purpose: To examine the audiometric outcomes of a footplate shoe (FPS) in total ossicular chain reconstruction prostheses (TORP) compared to TORP without shoe.

Materials And Methods: Retrospective cohort study of patients who underwent TORP from 2010 to 2021 at a tertiary children's hospital. Patients without audiograms or unknown FPS status were excluded.

High-velocity traumatic amputations of the proximal upper extremity are devastating to the patient and represent an extreme surgical challenge to the treatment team. The hand surgeon must simultaneously battle devascularization with timely microvascular anastomosis, gross contamination with meticulous debridement, and amputation with stable fixation. In restoring a functional extremity, many of these goals are in contention with each other.

Objectives: Tinnitus is a common otologic complaint which can range from bothersome to debilitating. Imaging is frequently utilized to rule out tumors, fractures, and other causes but can also cause significant medical and economic burden for patients. Furthermore, the pediatric population may require sedation for imaging.

Article Synopsis
  • Nerve transfers can help restore function in patients with severe ulnar neuropathy, and a new technique called the super-turbocharged end-to-side (STETS) transfer has been developed to connect the abductor digiti minimi (ADM) nerve to the ulnar motor nerve for better recovery.
  • A retrospective study involving 50 patients from 2020 to 2022 showed that those who underwent the STETS transfer experienced significant improvements in hand function and quality of life, measured through DASH scores and first dorsal interosseous muscle strength.
  • The results indicate that the STETS method may lead to better outcomes than traditional nerve transfers, suggesting the need for further research to confirm these

The ability to smile is impaired in patients with facial palsy, and objective parameters assessing smile symmetry to guide treatment are not well elucidated. This study seeks to identify objective facial measurements that relate smile recognition, perception of smile asymmetry, and perceived emotions from photographs of individuals with asymmetrical smiles compared with control photographs of individuals without smile asymmetry as measured by a photograph analysis application. Fifty-six photographs of smiles were categorized using objective perioral morphometric measurements (Emotrics).

Objective: The objective of the study is to evaluate the outcomes of surgical management options for cholesteatoma using a national database.

Study Design: Database analysis of the Pediatric Health Information System database to identify children undergoing surgical intervention for cholesteatoma from October 2015 to December 2022.

Methods: Patients were categorized by initial surgical modality: tympanoplasty (TM), tympanoplasty with canal wall-up tympanomastoidectomy (TM-CWU), and tympanoplasty with canal wall-down tympanomastoidectomy (TM-CWD).

Background: Deoxycholic acid (ATX-101) is a drug administered by subcutaneous injection for local fat reduction. However, ATX-101 treatment has been reported to cause marginal mandibular nerve injury with noticeable functional deficits when targeting submental fat. As a cytolytic agent with some selectivity for adipocytes, ATX-101 may damage the lipid-rich myelin surrounding peripheral nerves.

Introduction: This study investigates the intersection of ballistic injuries, geography, and Area Deprivation Index (ADI). We hypothesized that both ADI and geography are correlated with incidence of upper extremity ballistic injuries. Further, we characterize and compare 2 distinct upper extremity gunshot injury populations presenting to our institution: those sustaining violent ballistic injuries and those who suffer an accidental, self-inflicted injury.

Surgery remains the mainstay of cholesteatoma management. Through advancement in technique and technology, the available surgical approaches have expanded to include not only the traditional procedures, but also endoscopic procedures, canal wall reconstruction procedures, mastoid obliteration, and retrograde mastoidotomy. Selection of management technique will depend on disease characteristics, patient factors, and surgeon preference.

Article Synopsis
  • PFAPA syndrome is a common recurring fever condition in children, and tonsillectomy is explored as a treatment, raising concerns about potential postoperative fever which may complicate diagnosis.
  • A study conducted on PFAPA patients who had tonsillectomy from 2013 to 2022 found that only 1.6% experienced immediate postoperative fever, indicating low risk.
  • The findings suggest that tonsillectomy does not increase the likelihood of postoperative fever in PFAPA patients, which could impact treatment management strategies.

Activated lung ILC2s produce large quantities of IL-5 and IL-13 that contribute to eosinophilic inflammation and mucus production following respiratory syncytial virus infection (RSV). The current understanding of ILC2 activation during RSV infection, is that ILC2s are activated by alarmins, including IL-33, released from airway epithelial cells in response to viral-mediated damage. Thus, high levels of RSV neutralizing maternal antibody generated from maternal immunization would be expected to reduce IL-33 production and mitigate ILC2 activation.

Objective: Utilizing a novel histopathological scoring system and subglottic stenosis (SGS) rabbit model, we aimed to compare degrees of inflammation and severity of narrowing in the subglottis between two minimally invasive therapeutic modalities: endoscopic balloon dilation (EBD) alone versus EBD with placement of a bioabsorbable ultra-high ductility magnesium (UHD-Mg) alloy stent.

Methods: SGS was induced endoscopically via microsuspension laryngoscopy in 23 New Zealand white rabbits. The control group (n = 11) underwent EBD alone, the study arm (n = 12) underwent EBD with implantation of bioabsorbable UHD-Mg alloy stents.
