Sialolithiasis is an uncommon condition of unclear etiology. This study represents an initial attempt to quantify the prevalence of smoking and diuretic therapy in a population of patients with sialolithiasis.

Airway hemangiomas can be a life-threatening complication of PHACE syndrome. At our institution, 52% of all PHACE subjects were diagnosed with airway hemangiomas. Early detection of airway involvement is paramount. Given the high rates of airway hemangiomas, we recommend performing direct laryngoscopy and bronchoscopy in all PHACE patients with respiratory symptoms. We recommend having a low threshold for airway evaluation in asymptomatic PHACE patients, especially those who will not be otherwise started on propranolol.

Rationale: Subglottic edema and acquired subglottic stenosis are potentially airway-compromising sequelae in neonates following endotracheal intubation. At present, no imaging modality is capable of in vivo diagnosis of subepithelial airway wall pathology as signs of intubation-related injury.Objectives: To use Fourier domain long-range optical coherence tomography (LR-OCT) to acquire micrometer-resolution images of the airway wall of intubated neonates in a neonatal intensive care unit setting and to analyze images for histopathology and airway wall thickness.Methods: LR-OCT of the neonatal laryngotracheal airway was performed a total of 94 times on 72 subjects (age, 1-175 d; total intubation, 1-104 d). LR-OCT images of the airway wall were analyzed in MATLAB. Medical records were reviewed retrospectively for extubation outcome. Measurements and Main Results:Backward stepwise regression analysis demonstrated a statistically significant association between log(duration of intubation) and both laryngeal (P , 0.001; multiple r 2 = 0.44) and subglottic (P , 0.001; multiple r 2 = 0.55) airway wall thickness. Subjects with positive histopathology on LR-OCT images had a higher likelihood of extubation failure (odds ratio, 5.9; P = 0.007). Longer intubation time was found to be significantly associated with extubation failure.Conclusions: LR-OCT allows for high-resolution evaluation and measurement of the airway wall in intubated neonates. Our data demonstrate a positive correlation between laryngeal and subglottic wall thickness and duration of intubation, suggestive of progressive soft tissue injury. LR-OCT may ultimately aid in the early diagnosis of postintubation subglottic injury and help reduce the incidences of failed extubation caused by subglottic edema or acquired subglottic stenosis in neonates.Clinical trial registered with www.clinicaltrials.gov (NCT 00544427).

Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidencebased review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. Results: The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. Conclusion:This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.

Objectives 1) To assess the current status of pediatric intracapsular tonsillectomy in the United States, and 2) To apply lessons from the scientific literature and adoption of surgical innovation to predict future trends in pediatric intracapsular tonsillectomy. Methods This was a cross‐sectional survey study and literature review. An anonymous survey was sent to all members of the American Society of Pediatric Otolaryngology (ASPO) to determine current practices in pediatric tonsillectomy. Statistical analysis was performed to compare differences in individuals who perform intracapsular tonsillectomy as opposed to extracapsular tonsillectomy. A literature analysis of the adoption of new technological advancements and innovative surgical techniques was then performed. Results The survey was sent to 540 pediatric otolaryngologists with a response rate of 42%. Of all respondents, 20% currently perform intracapsular tonsillectomy. The primary reason cited for not performing the procedure was concern for tonsillar regrowth. Time in practice, practice setting, and fellowship status was not associated with an increased incidence of intracapsular tonsillectomy. Conclusions Only 20% of pediatric otolaryngologist respondents in the United States perform intracapsular tonsillectomy. Based on the documented advantages of intracapsular tonsillectomy over extracapsular tonsillectomy and an analysis of adoption of novel surgical techniques, we predict a paradigm shift in the specialty toward intracapsular tonsillectomy.
