[Esophageal insufflation test in secondary voice reconstruction].
OBJECTIVE
To restore the alaryengeal patients' enunciation function, reduce operative trauma, increase the accuracy of detecting the success of secondary voice restoration and evaluate objectively the practical clinical significance of esophageal insufflation test.


METHODS
Esophageal insufflation test and secondary voice restoration were done for 45 alaryngeal patients, especially those with negative results of esophageal insufflation tests.


RESULTS
It showed that the success rate of voice rehabilitation in patients with negative insufflation test but no intact pharyngeal constrictor was 94.7%(36/38), in those with positive insufflation test was 100%(7/7) uniformly. The postoperative pronounciation performance was better than that at the test time.


CONCLUSIONS
Esophageal insufflation test is a useful procedure in predicting the postoperative pronunciation, but could be influenced by many factors, so it can not be used as the only test for estimating the postoperative pronunciation.
