Foreign body Swallows with Airway Affection in Pediatrics.

Aims: The current work aimed at evaluating how FBI can cause respiratory distress and stridor as well as their severity according to age, gender, lodgment site, and type of the object. Factors influencing morbidity and mortality among studied patients will be deliberated as well.

Methods: It is a hospital-based descriptive study where all children between birth and 16 years of age who were admitted to Sohag University Hospital, Egypt from January 1st, 2018, to December 31st, 2020, for FBs removal were analyzed.

Internal Hypopharyngeal Cyst: A Review of Literature.

Detailed information on the hypopharyngeal cyst presentation, terminology, classification, diagnosis, management, and possible complication is scarce though it would lead to life-threatening symptoms. This review article, therefore, meticulously presents and analyzes the majority of the pertaining literature. In this context, a particular emphasis has been placed on the embryological development of the branchial arches while discussing each entity that would improve the current understanding of different pharyngeal cyst's pathologies.

A branchial cyst of the pyriform fossa transoral laser resection: a case report.

Pyriform sinus malformations represent rare third and fourth branchial anomalies. Fistulae at the latter site were initially described and make up less than 1 % of all brachial anomalies. They may be discovered incidentally, or may present as a neck mass with recurrent infection, dysphagia, or airway compromise, and can be an unusual cause of dysphonia in infant and children.

Localization and regulation of aquaporins in the murine larynx.

Conclusion: Expression of aquaporins (AQPs) in the vocal folds and the parasympathetic regulation of AQPs in the laryngeal glands may be important for controlling laryngeal secretion and vocal fold hydration. These findings are thought to be an initial step towards understanding potential mechanisms of water flow through the vocal fold surface.

Objectives: Lubrication of the vocal folds is important for phonation and laryngeal defense.
