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\u00a0days and 6 weeks after the operation. The acoustic features of vowels were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>The operation had no significant effects on vowel quality.
