Hypoharyngeal perforation with production of an esophageal pseudodiverticulum in the newborn is reviewed. Two new cases are reported and the clinical signs, very similar to those of tracheoesophageal fistula with esophageal artresia, commented upon. The radiological findings of the lesion are discussed, and hints on conservative treatment, advanced.
