The
anatomy of oral cavity in Down syndrome is characterized
by hypotonic macroglossia, small oral cavity, and
narrow palate wjth high-arch shape. Because of such
characteristjcs, patients show diffjcu'ty
in articulationlresonance and phonation.
They a'so suffer from respiratory diffjculty due
to narrow upper respiratory tract which is exaggerated
by hypertrophied tonsil and adenoid. So far we operated
on l00 children with Down syndrome for partial glossectomy
in average volume of 4.6 cc. We analyzed the results
by means of questjonnajres and speech test with
multi-speech model 3700 program before and after
the operation. After partial gIossectomy, we observed
that they ould close their lips comfortably, and
rt can mjtigate the stigma of Down syndrome. We
ould also observe the improvement in voice quality,
pitch, resonance and articula-tion. Through paired
t-test using SAS, we analyzed value of Fl, F2-Fl,
and changes of fundarTkntal frequency(Fo).After
partial glossectomy, anteriorty positioned tongue
of Down patients became significantly smaller in
size and be located posteriorly.
