title: Use of cephalometry in diagnosing resonance disorders.
abstract: A comparative cephalometric study of the oronasopharyngeal dimensions was carried out on 20 patients with normal speech, 20 patients with nasality and 22 patients with cleft palate speech, with the help of cephalometric landmarks given by Proffit and McGlove, Proffit et al., and Ricketts. The data obtained were subjected to statistical analysis, to determine whether there were any significant changes in oronasopharyngeal dimension between the various groups. It was concluded from the obtained data that there was an increase in the width and depth of the nasopharynx, with a consequential increase in the pharyngeal cavity volume in patients with cleft palate speech when compared with patients who had normal speech and those who had nasality.
