Epiglottis anomaly associated with Pierre Robin sequence (PRS) is a rare occurrence. To the knowledge of the authors, this is the first reported case of epiglottic anomaly associated with PRS. Doctors should remain aware of this atypical presentation in a PRS patient, and the presented case highlights the clinical challenges that must be met to ensure effective treatment of the defect in terms of compromised respiration, swallowing and feeding.
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.
OBJECTIVE: To characterize the histopathologic characteristics of the cricoarytenoid joint (CAJ) as a means to understand the mechanisms of vocal cord fixation in children after prolonged intubation. DESIGN: Histologic analysis of laryngeal specimens obtained from infants who had died secondary to various causes and who had been intubated from 1 to 30 days. MAIN OUTCOME MEASURE: Histopathologic characteristics of CAJ. RESULTS: Laryngeal specimens from infants who had been intubated for prolonged periods of time demonstrated evidence of hemorrhage, infection, inflammation, and fibrosis within the CAJ. Furthermore, a statistical correlation was found between the length of intubation and the presence of these histologic abnormalities. CONCLUSIONS: To our knowledge, this is the first study to demonstrate histologic changes in the CAJ in laryngeal specimens of children who have been intubated for prolonged periods of time. Such histological changes in the CAJ could explain the mechanism of vocal cord immobility in children after intubation.
