Abstract
|
|
|
The purpose of this study was to evaluate hypernasality, nasal air emission, glottal stop, articulation disorder in patients with velopharyngeal incompetency (V. P. I.) and to analyze speech improvement after pharyngoplasty.
In this study 61 patietns with velopharyngeal incompetency were tested, and in patents with pharyngoplasty speech problems before pharyngoplasty were compared with those after pharyngoplasty.
@ES The results obtained are as follows:
@EN 1. There are few speech problems in pronouncing the vowel sounds.
2. There are many spech problems in pronouncing the pressure sounds and few speech problems in non-pressure sounds.
3. Speech problems in patients with cleft palate are influence not by anatomical defect but by severity of velopharyngeal incompetence after palatorrhaphy.
4. Operation methods which decrease the valopharygeal incompetence must be considered for reducing the speech problems.
5. Among the 61 cases with V. P. I. 19 cases (31%) showed nasal air emission and 24 cases (39%) showed glotal stop.
6. Pharyngoplasty is of benefit to primary precipitating components such as hypernasality, nasal air emission but of no benefit to secondary compensating compont such as glottal stop.
7. There was no signifference in speech improvement between pre-and post-pharyngoplasty (p<0.05).
