Abstract

In assessing portal function, we have to use both direct and indirect objective methods. Among the direct measures of endoscopic. radiological and ultrasound studies the endoscopic examination may be more reasonable one.
Surgeons seem to be well aware of wide variety of ways to treat velopharyngeal incompetence.
It is more complex problem to lead normal speech in cleft palate patients with distorted speech, because it includes not only physiological and anatomical prerequisites but also habitual and environmental factors. On the aspect of anatomical and physiological factors the size of port plays an important role to achieve normal port function in surgery of pharyngeal f lap.
Even skillful surgeons could have been experienced occasionally inappropriate portal function following secondary surgery.
In this case. the patient had complained about speech disturbance and hypernasality despite of previous pharyngeal flap operation for velopharyngeal incompetence. The nasend - oscopic examination revealed marked discrepancy in size between the right and left lateral ports.
We had applied a newly designed surgical procedure, bilateral muco-salpingopharyngeal muscle transfer, to correct the size discrepancy of lateral ports.
Although further evaluation and follow-up study with accumulation of cases are necessary to reach a conclusion, the objective evaluation assessed by nasendoscopic, aerodynamic and articulatory tests were good enough to recommend trial of this procedure to the patients with uncontrolled velopharyngeal incompetence following pharyngeal flap operation.
