“…The principal papers on the more serious form of palatal palsy, which apparently does not recover in the early months, are those by Cohen (1955), Worster-Drought (1956), Graham (1964), and Ardran et al (1965). Cohen (1955), in his paper on congenital dysphagia, described five groups of cases: (a) cortical atrophy, hypoplasia, or agenesis (3 cases: one with spastic quadriplegia, one mentally defective child with isolated bulbar palsy, one defective child with paralysis of the cervical sympathetic and an anomalous right subclavian artery); (b) familial autonomic dysfunction (Riley, 1957, 2 cases); (c) familial paralysis of palate (1 case); (d) amyotonia congenita (1 case); (e) neurogenic oesophageal dysfunction (6 cases: cardiospasm, short oesophagus with spasm, Pierre Robin syndrome with chalasia, tracheo-oesophageal fistula, short oesophagus with hiatus hernia, and a child with atresia of the right ear, paralysis of the facial nerve, inspiratory stridor, hoarseness, and an oesophageal pouch).…”
