Saccular cyst is a rare lesion of larynx causing respiratory obstruction and stridor in neonates and infants. Herein we present a case of a 4 year old who presented to us with intermittent respiratory distress and stridor. Fibreoptic bronchoscopy showed the presence of saccular cyst overhanging the anterior part of right vocal cord. Endoscopic marsupialization of cyst is done using laryngeal microdebrider with stripping of cyst lining. Saccular cyst should be considered in the differential diagnosis of children presenting with intermittent stridor.

Gastric choristoma (GC) is a relatively common congenital condition characterized by the presence of heterotopic gastric tissue outside the bounds of the gastric cavity. Although GCs may occur anywhere along the alimentary tract, they rarely occur in the hypopharynx. Hypopharyngeal GCs often declare themselves clinically during the neonatal period with life-threatening obstructive respiratory symptoms and/or feeding difficulty. We present a case of GC of the posterior pharyngeal wall manifesting as progressive dysphagia with failure to thrive and intermittent stridor.

In this report we describe a 3-year-old patient who had hypocalcemia caused by pseudohypoparathyroidism and who had intermittent inspiratory stridor, retractions, and dyspnea. We propose that the symptoms were intermittent because he periodically hyperventilated. This hyperventilation induced transient drops of his already low serum calcium level and caused laryngismus. We review the mechanisms by which hypocalcemia causes laryngeal tetany
