Abstract
OBJECTIVE:

The effects of the genioglossal
muscle advancement on phonetic quality of speech were studied analyzing
the acoustic features of vowel sounds.

STUDY DESIGN AND SETTING:

The
study group consisted of 5 men suffering from partial upper airway
obstruction during sleep. To prevent tongue base collapse, genioglossal
muscle advancement was made with chin osteotomy without hyoid myotomy
and suspension. The speech material consisted of 8 vowels produced in
sentence context repeated 10 times before the operation, and 10 days and
6 weeks after the operation. The acoustic features of vowels were
analyzed.

RESULTS:

The operation had no significant
effects on vowel quality. Only for 2 of the subjects the pitches changed
systematically due to the operation.

CONCLUSION:

According
to the acoustic analysis, genioglossal muscle advancement with chin
osteotomy has no effects on vowel production. Some short-term changes
were observed, but these changes were highly individual.

SIGNIFICANCE:

The operation seems to have no potential to change vowel production.
