Abstract:
OBJECTIVETo observe the mobility of levator veli palatini muscle during speech in patients with repaired cleft palate and cleft lip.
METHODSMRI of the levator veli palatini muscle was taken during speech and breathing in three groups of patients: control group (cleft lip only, 8 cases), velopharyngeal incompetence (VPI) group (7 cases), velopharyngeal competence (VPC) group (10 cases). The length and the angle of the levator veli palatini muscle were compared.
RESULTSThe changes of the length and the angle during speech were not significantly different among the three groups (P > 0.05). The ratio of length changes when speaking "a", "i", and "m" are (13.5 ± 11.7)%, (11.1 ± 10.8)%, (8.2 ± 14.3)%. Mean angle of pronouncing "a", "i", and "m" are [(43.18 ± 4.984)°, (43.08 ± 4.879)°, (39.48 ± 5.046)°]. The levator veli palatini muscle contracted progressively form "m", "i", to "a".
CONCLUSIONSThe mobility of the levator veli palatini muscle in patients with repaired cleft palate and cleft lip only is basically the same.
