OBJECTIVES: This study aims to investigate the incidence and severity of obstructive sleep apnea (OSA) in cleft patients with velopharyngeal insufficiency (VPI) after pharyngeal flap surgery (PFS) and explore the influence of operation age. METHODS: A retrospective study was conducted in 82 cleft patients after PFS. The patients were divided into two groups according to their age at the time of surgery. The incidence and severity of OSA were assessed at least 1.2 years (mean 6.0 years) postoperatively by polysomnography (PSG). RESULTS: The incidence rates of OSA were 20% in the adult group and 31% in the child group. No significant difference was found between the two groups ( CONCLUSIONS Some patients still have OSA average of 6.0 years after PFS, and operation ageis unrelated to the incidence and severity of OSA.

OBJECTIVETo study the Chinese intelligibility of patients with velopharyngeal incompetence (VPI).

METHODS100 patients with VPI and 32 normal students were selected for this study. Of 10 patients, 15 with cleft palate, 21 with congenital velopharyngeal incompetence, 56 with post-palatoplasty VPI and 8 with post-pharyngoplasty VPI. Chinese intelligibility was measured by three speech pathologists and relation between degree of abnormal articulation and Chinese intelligibility were studied.

RESULTSChinese intelligibility of the controls was 99.0% and the patients with VPI were 35.2%. Of the patients, the cleft palate was 19.9%, the congenital velopharyngeal incompetence was 32.8%, the post-palatoplasty VPI was 40.3% and the post-pharyngoplasty VPI was 35.2%. The data showed obvious difference among the controls and sub-types of VPI (P < 0.01).

CONCLUSIONS(1) Chinese intelligibility of VPI accompanied with hypernasality is worse. (2) Of misarticulation of VPI, the cleft palate is the worst, in turn the others are the congenital velopharyngeal incompetence, the post-pharyngoplasty VPI and the post-palatoplasty VPI.

OBJECTIVETo evaluate the velopharyngeal status of cleft palate patients after operation in silent mode by visual analog scale.

METHODSA total of 82 patients with cleft lip and palate after operation were examined by nasopharyngeal fiber endoscopy with 11 voice samples. The velopharyngeal status was evaluated by three experienced experts using qualitative method and visual analog scale (VAS) method in silent mode. The Spearman correlation relationship was analyzed between VAS value and qualitative grade. The VAS value range of 10 non-nasal consonant voice samples was divided according to qualitative classification.

RESULTSVAS values could accurately reflect the outcome of the qualitative classification. The poorer the velopharyngeal status was, the lower the VAS value, and vice versa. The whole effectiveness of value range was greater than 70%.

CONCLUSIONSVAS values can accurately reflect the outcome of the qualitative classification about velopharyngeal function, and VAS value grading velopharyngeal status is reliable. This study proposed VAS values range standards for different velopharyngeal qualitative classification.

OBJECTIVETo analyze the formant frequency of vowels in the sequence therapy of patient with cleft palate.

METHODSThe formant frequency of vowels [a], [e], [i], [u] of normal children and postoperative patients with and without speech therapy was measured and analyzed by VS-99.

RESULTS1. The mean value of F1, F2, F3 of [a] did not show significant difference among the three groups (P > 0.05). 2. The difference of mean value of [e] was significant between control group and pre-speech-therapy group, and between pre-speech-therapy and post-speech-therapy group (P < 0.05), but no significant difference was found between post-speech-therapy and control group(P > 0.05). The mean value of the formant in post-speech-therapy was higher than that of pre-speech-therapy. 3. The difference of mean value of [i] was significant between pre-speech-therapy and post-speech-therapy (P < 0.05), the mean value of F2, F3 in post-speech-therapy group decreased significantly compared with control (P < 0.05). 4. The difference of mean value of [u] showed significance between pre-speech-therapy and post-speech-therapy (P < 0.05), while the differences among other groups were insignificant (P > 0.05).

CONCLUSIONSurgical repair of cleft palate cannot make all patients obtain perfect Velopharyngeal competence (VPC), while speech therapy can improve patient's pronunciation. Speech spectrum analysis can judge the effect of cleft palate therapy objectively.
