A method for palatography has been described for patients to be helped by the Plastic Surgeons and the Speech Therapists. Information about the anatomical and physiological conditions of the soft palate is given. The examination was done on 50 patients to study velo-pharyngeal closure in adults and in children, during normal position, in various types of phonations and while blowing. The examination is a simple one, without requiring any special equipment or special techniques; it is helpful in the diagnosis and management of cleft palate abnormalities. It is specially recommended in cases where surgery is contemplated or speech therapy is in progress. The following are the conclusions from this Preliminary Report.
- 1The soft palate exhibits an oscillary movement during velo-pharyngeal closure, and does not remain continuously in contact with the pharyngeal wall.
- 2With different sounds, the degree of elevation of the soft palate is different.
- 3There is no relation between the length of the soft palate and pharyngeal depth.
- 4During phonation, the elevation of the soft palate varies inversely with its length; it is also related to the age.
- 5The posterior pharyngeal ridge is a compensatory response, found in individuals with cleft palate, helping in velopharyngeal closure.
