Refinement of velopharyngoplasty in patients with cleft palate by covering the pharyngeal flap with nasal mucosa from the velum.

The velopharyngoplasty performed using the popular Sanvenero-Rosselli method improves the speech quality of patients with cleft palate suffering from persistent velopharyngeal insufficiency despite successful closure of the hard and soft palates. However, often a relatively narrow pharyngeal bridge results due to healing not only by granulation and scar contraction, but also due to the insertion of the inferior tip of the flap into a narrow bed. Elevation of two velar flaps with nasal mucosa to cover the exposed muscular undersurface of the pharyngeal flap produces a broader recipient bed into which the pharyngeal flap can be spread. The speech quality of 27 patients treated with this modified method (group B) was compared with that of 27 patients without this modification (group A). Eight weeks after velopharyngoplasty (followed by uneventful wound healing) the speech quality of group B was significantly better than that of group A (p<0.03 MannWhitney U-test). This difference was even more evident when comparing the preoperative with the postoperative speech quality (p<0.005). Thus, covering the exposed muscular layer of the pharyngeal flap with nasal mucosa of the velum is an important modification of velopharyngoplasty for the improvement of speech quality.

[Speech improvement with velopharyngoplasty in patients with lip-jaw-palate clefts].

BACKGROUND: Despite successful closure of the hard and soft palate and intensive speech therapy a velopharyngeal insufficiency is not completely avoidable in each case of cleft palate. An improvement by velopharyngoplasty should be possible. PATIENTS AND METHODS: Two hundred and ninety patients suffering from cleft palate were examined before and one year after velopharyngoplasty according to Sanvenero-Rosselli. Four main symptoms of the affected speech were assessed: changes of the resonance, inappropriate nasal air emission, articulary disorders (deviations from articulation areas), and non-physiological facial expression during speaking, each divided into three grades. Afterwards, the complete speech quality was classified. RESULTS: Assessing the symptoms separately and summarised the therapy including velopharyngoplasty was suitable to improve the speech quality in 83.1% of the cases, resulting in a widely unaffected speech. The improvement was greater in younger patients undergoing operation (Gamma-test, p < 0.001). But the final results were independent from age due to poorer initial situation in younger patients (Gamma-test, p < 0.001). CONCLUSIONS: The velopharyngoplasty is an important method for repair of velopharyngeal insufficiency in patients with cleft palate. In each individual case it is necessary to consider carefully if and when this operation should be performed. An intensive interdisciplinary co-operation of all specialists involved in the treatment is indispensable.

Unilateral cleft lip and palate. Relationship between morphology of the dentition and functional parameters of the tongue.

The relationship between orthodontic and logopedic findings was evaluated with statistical contingency analysis. The investigation was focused on selected dentomorphologic parameters and oral function/malfunction of 100 patients between 3 and 7 years of age with unilateral cleft lip and palate. For further classification into contingency tables "normal" and "abnormal" attributes were defined. Interdependencies between observed findings and their probable frequencies were calculated and represented in diagrams by means of statistical parameters such as the contingency coefficient. Scatterplots of the calculated coefficients showed a characteristic pattern corresponding to clinical experience. While overjet and transversal occlusion are strongly associated with oral functions, overbite tends not to be associated with oral functions. The contingency coefficient calculated from sagittal and transversal orthodontically relevant conditions of occlusion and incorrect tongue position as well as incorrect swallowing tends to be stronger than that of "abnormal" morphologic parameters and an incorrect tongue position during speech. The longitudinal study of lip position and the 3 investigated morphologic parameters revealed strongly associated contingency coefficients.

[Early education of children with clefts with special regard to logopedics].

UNLABELLED: Necessity for early education: --general early education goal, contents, methods and forms of organization, --special early education--rehabilitative logopaedics goal, contents, methods and forms of organization incoherent logopaedic care coherent logopaedic care instruction of parents and co-operation with nurseries and nursery schools to realize early education. CONCLUSIONS: realization of the rehabilitative-paedagogical early education of the cleft child.
