Objective: To discuss the role of laryngotracheal reconstruction (LTR) in granular cell tumor (GCT) and to highlight the importance and seriousness of GCT in pediatric airway cases.
Methods: A historical literature review was performed and a GCT case from the University of Miami Pediatric Otolaryngology Clinic is presented to highlight the role of LTR in the treatment of GCT.
Results: A case of a GCT of the laryngotracheal airway is reported and the management is discussed. Histological discussion and a review of the literature are included regarding GCT. This case is the third reported in the English literature of two synchronous GCT lesions of the upper airway repaired with a laryngotracheal reconstruction.
Conclusions: In the authors' experience once conservative management consisting of endoscopic debulking has failed the treatment of choice for GCTs of the pediatric airway that are unresectable is a single stage laryngotracheal reconstruction with negative frozen section pathology to assure total wide local excision.

In this study, we examined the correlation between anatomical dimensions, spray administration parameters, pressure drop across 40 pediatric nasal cavities, and in vitro posterior drug delivery (PDD) using Nasacort ALLERGY 24HR and FLONASE SENSIMIST nasal suspensions sprays, with different nozzle and actuation designs. The importance of each parameter and their interaction in the outcome (PDD) was evaluated. To do so, initially we measured anatomical and administration-related parameters, and the pressure drop of each cavity.

Exposure to influenza A virus (IAV), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) is well-known to increase the risk of pneumonia in humans. Type I interferon (IFN-I) is a hallmark response to acute viral infections, and alveolar macrophages (AMs) constitute the first line of airway defense against opportunistic bacteria. Our study reveals that virus-induced IFN-I receptor (IFNAR1) signaling directly impairs AM-dependent antibacterial protection.

Asthma, a widespread chronic inflammatory disease can contribute to different degrees of lung function damage. The objective of this study is to explore the potential effects of nitric oxide synthase (NOS) inhibitors in asthma using mice model induced by ovalbumin (OVA). BALB/c mice were treated with OVA to establish an asthma model.

Background And Aim: Tonsil-surgery is a common treatment for tonsillitis and upper-airway obstruction. Health benefits are a key point of clinical concern. Aim: To evaluate health benefits 6-months after pediatric tonsil-surgery and to examine the influence of the perioperative period on health-related quality of life (HRQoL).

Oral and maxillofacial diagnostic imaging is of paramount importance in dental clinical diagnosis, treatment planning, and follow-up procedures. Periapical radiographic examination and numerous panoramic systems are used in routine clinical dental practice. Cone beam CT is widely used and currently the method of choice in oral and maxillofacial implantology, endodontics, maxillofacial surgery, periodontics, degenerative temporomandibular joint disease, orthodontics, airway studies, sleep disorders, and forensic dentistry.
