[Primary and secondary care of cleft lip and palate in the lip-palate center in Bruxelles].

Since 1987, we chose a neonatal repair of the cleft lip and nose and closure of the cleft palate at 3 months of age. Ventilation tubes are systematically inserted in the drums at time of palatoplasty. Alveolar clefts are grafted when canine erupts. Secondary correction, which might be early, are scheduled according to functional, aesthetic or psychological demands. A interdisciplinary follow-up by a stable and united team is essential for an adequate management of sequels.

A child with signs of developmental apraxia of speech with whom a palatal lift prosthesis was used to manage palatal dysfunction.

A client is described who exhibited a large number of characteristics consistent with developmental apraxia of speech (DAS). The exhibited symptoms included excessive nasal resonance and nasal emission of air due to velopharyngeal port dysfunction, for which successful management was achieved by use of a palatal lift prosthesis. The results of the client's use of the lift, in conjunction with her speech and language remedial programming, is presented.

[Velopharyngeal closure in adolescents after repair of cleft lip, jaw, palate or isolated cleft palate].

We examined two groups of teenagers (between 13 and 21 years of age) who had been surgically treated as small children for congenital cheilognathouranoschisis or cleft palate. A group of 62 teenagers had been treated by the Dept. of Orthodontics at the University of Erlangen-Nuremberg, the other group of 61 by the Dept. of Orthodontics at the University of Rostock. There were differences between the two departments in sequence and time of the surgical closure as well as in the frequence of velopharyngoplasties. The velopharyngeal closure was examined in all patients by means of a flexible fibre endoscope which was pushed forward endonasally up to the choanae. Simultaneously we judged the audibility of the nasal perflation while pronouncing /k/. A residual gap during articulation of /k/ with clearly audible or alternately clearly and discreetly audible nasal perflation was noted in 8 subjects in Erlangen and 14 subjects in Rostock. In subjects whose velum moved only anterior-posteriorly, closure was likely to be less good than in those with a circular closing mechanism of velum and lateral and/or posterior parts of the pharyngeal musculature. In rare cases we found a good velopharyngeal closure in spite of a large gap between the velum and the posterior pharyngeal wall at rest. This was the case when the velum moved more against the upper than the posterior wall of the nasopharynx. Velopharynxplasty did not reduce nasal airflow in case of insufficient function of the velar muscles. Differences in the mode of velopharyngeal closure might be due to statistically significant regional differences in skull structure.(ABSTRACT TRUNCATED AT 250 WORDS)

[Ear manifestations in adolescents after closure of lip-jaw-palate- or isolated palatal clefts].

We examined two groups of teenagers who had been surgically treated as small children for cleft palate. Most patients were between 13 and 21 years of age. One group had been looked after by the Dept. of Orthodontics at the University of Erlangen-Nürnberg, the other by the Dept. of Orthodontics at the University of Rostock. There were differences in sequence and time of the surgical closure between the two departments. Additionally, 60% of the people treated in Rostock had a velopharyngoplastic, which was rarely the case in Erlangen. In both groups only a few patients had been seen by an ENT-doctor regularly. Only some patients had been previously treated with tubes. There was one patient in each group with a bilateral, most likely genetically determined, sensorineural hearing loss. In Erlangen we examined 66 teenagers (132 ears). Six ears had been previously treated with one or more tympanoplasties. 10 ears needed further treatment due to a seromucotympanon, adhesions, perforations of the ear drum, suspicion of cholesteatoma or insufficient improvement of hearing after previous tympanoplasty. Another 18 ears showed signs of former inflammations. The control group in Rostock included 63 patients (i.e. 126 ears). 14 of the ears examined had undergone one or more tympanoplasties previously. 13 other ears needed further treatment for seromucotympanon, adhesions, perforations of the ear drum, insufficient improvement of hearing after tympanoplasty or cholesteatoma. Residuals due to prior inflammations were found in another 26 ears. Possible reasons for the different occurrence of middle ear problems in both groups are discussed.

Von Langenbeck or Wardill procedures for primary palatal repair in patients with isolated cleft palate--speech results.

Sixty-six patients operated on for isolated cleft palate were evaluated as adults, and their speech was assessed clinically. Forty-four had undergone a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at the age of 18 months. Speech was judged subjectively by the patients themselves, and perceptual assessment was made by three speech pathologists. The remaining speech problems, mainly hypernasality, were moderate or severe in 7 (16%) of the patients in the von Langenbeck group, and in 7 (32%) in the Wardill group. On the other hand, the patients in the Wardill group had fewer fistulas closed, and fewer velopharyngoplasties. There were no significant differences between the two methods regarding speech in adulthood. The Wardill method produced significantly more scar tissue clinically, which carries the potential risk of inhibition of facial growth. The present speech results will therefore be weighed against the outcome of maxillofacial growth for these patients.

Adult skeletal profile in isolated cleft palate: a comparison of the von Langenbeck and Wardill procedures for primary repair of the palate.

Sixty-four adult patients operated on for isolated cleft palate were evaluated with regard to facial skeletal morphology using conventional radio-cephalometry. Dental occlusion was assessed clinically. Forty-two had had a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at 18 months. The mean error of the method was 0.7 degree for angular, and 0.9 mm for linear, measurements. The group with clefts had less maxillary prognathism (s-n-ss), more maxillary inclination (NSL/NL), more retroclined lower incisors (ILI/ML), and shorter total and upper facial heights (n-gn, n-sp) compared with the reference group. Multiple regression analysis was used to evaluate differences between the two treatment regimens. Explanatory variables in addition to surgical technique were sex, severity of cleft, and presence of a velopharyngeal flap. Only one variable, lower incisor inclination (ILI/ML), was different for the two regimens. Ten (24%) in the von Langenbeck group had a lateral cross-bite compared with one (5%) in the Wardill group. Other variables in a multivariate regression analysis were affected by sex and severity of cleft to various degrees. This study showed no obvious differences in facial skeletal morphology that could be attributed to surgical technique. Factors other than technique, including sex, age, and severity of cleft merit attention.

Functional results with the team care of cleft lip and palate patients in Bergen, Norway. The Bergen Cleft Palate-Craniofacial Team, Norway.

There is international consensus about some fundamental elements concerning treatment of cleft lip and palate (CLP): (1) multidisciplinary teamwork, (2) centralization, (3) team continuity, (4) long-term treatment planning (from birth to adulthood), (5) documentation, (6) evaluation, (7) follow-up studies, (8) research and (9) quality assurance. Every year 120-140 children are born with CLP in Norway (2 per 1,000 live births). For more than four decades the treatment of CLP has been centralized to the University Clinics in Oslo and Bergen. The cost of treatment as well as the travel expenditures for patients born with facial clefts are paid by the Norwegian government (social security). In a speech study of 180 6-year-old children with CLP/CP first operated in Bergen during 1973-1981, normal resonance was found in 76.7% of the children, moderate hypernasality in 11.7%, while 11.6% had marked hypernasality.

Myofibroblasts in palatal wound healing: prospects for the reduction of wound contraction after cleft palate repair.

The surgical closure of orofacial clefts is considered to impair maxillary growth and dento-alveolar development. Wound contraction and subsequent scar tissue formation, during healing of these surgical wounds, contribute largely to these growth disturbances. The potential to minimize wound contraction and subsequent scarring by clinical interventions depends on the surgeon's knowledge of the events responsible for these phenomena. Fibroblasts initiate wound contraction, but proto-myofibroblasts and mature myofibroblasts are by far the most important cells in this process. Myofibroblasts are characterized by their cytoskeleton, which contains alpha-smooth-muscle actin. Additionally, their contractile apparatus contains bundles of actin microfilaments and associated contractile proteins, such as non-muscle myosin. This contractile apparatus is thought to be the major force-generating element involved in wound contraction. After closure of the wound, the myofibroblasts disappear by apoptosis, and a less cellular scar is formed. A reduction of contraction and scarring might be obtained by inhibition of myofibroblast differentiation, stimulation of their de-differentiation, stimulation of myofibroblast apoptosis, or impairment of myofibroblast function. In this review, we will discuss all of these possibilities, which ultimately may lead to a better outcome of cleft palate surgery.

Speech results following late palatal surgery in previously unoperated Sri Lankan adolescents with cleft palate.

The speech of 18 Sinhala speaking patients over 11 years of age with previously unrepaired palatal clefts is presented preoperatively, 8 months postoperatively, and after two brief courses of speech therapy (8 and 12 months postoperatively). Speech was usually severely disordered in the unoperated patient. The postoperative results show that speech often remains disordered following surgery, but there is the potential for change in some patients when supported by intensive goal directed therapy.

Sri Lankan cleft lip and palate study model analysis: clefts of the secondary palate.

The study models of a group of adult Sri Lankan patients with clefts of the secondary palate were investigated. Tooth-size and arch-dimension comparisons were made with a comparable control group. Significant differences were found between the cleft and control groups in tooth sizes, chord lengths, and arch widths. The cleft group dimensions were generally smaller than those of the control group. Overjets were larger in the cleft group.

[Tooth development in children with cleft lip and palate. An international inquiry into unilateral cleft lip, jaw and palate].

In a cross-sectional study of 106 European children with unilateral complete cleft lip, alveolus and palate ranging from 10 to 15 years of age, dental maturity was determined using orthopantomograms. The method and standards (the 50th percentile line) of Demirjian were used. The study shows a significant delay of dental maturity in both male and female cleft-affected patients. This delay in tooth development supports Van Limborgh's theory that the origin of clefts is due to the delayed growth and development of parts of the dentofacial area.

Results of multidisciplinary management of bilateral cleft lip and palate at the Iowa Cleft Palate Center.

Bilateral cleft of the lip and palate is by many standards the most complex and severe form of the defect. The complexity and severity of the defect require an unusual degree of cooperation among all specialists and especially between the surgeon and the orthodontist. There are no published findings that we know about in which comprehensive data from a number of disciplines are reported for the same group of bilateral cleft patients. Fifty randomly selected patients with bilateral complete clefts were examined by the Iowa team and two orthodontists from other institutions. The evaluations revealed that a large number of patients over the age of 10 have multiple residual problems requiring further treatment. Only 23 percent of the older patients studied were judged to have had treatment completed by the surgeon, speech pathologist, and orthodontist. It is very difficult to state whether the results obtained by our team can be considered satisfactory because there are no comparable studies that have attempted to evaluate the same parameters in multidisciplinary management.

Feeding infants with cleft lip, cleft palate, or cleft lip and palate.

In assessing 143 infants with cleft lip and palate, we found feeding problems to vary with the patients' anatomic lesion. Effective feeding techniques were identified by first assessing the infant's ability to generate negative intraoral pressure and to move the tongue against the nipple and then by matching these deficits to appropriate feeding devices.

[Association of ectodermal dysplasia, cleft of the lip palate and "scrubbing-brush hair". Its situation in "D. E. F. syndromes" (ectodermal dysplasia, cleft of the lip and/or palate (author's transl)].

The "D. E. F.-syndromes" consist of ectodermal dysplasia, cleft of the lip and/or palate (fente labiale et/ou palatine). This group includes the A. E. C.- and the E. E. C.-syndromes. We are reporting two cases of D. E. F.-syndrome, in which there was a very particular hair dysplasia, which we named "scrubbing-brush hair". The first case was a boy. The disease was probably transmitted on the dominant autosomal mode. The ectodermal dysplasia was of hypohidrotic type. The second case was also observed in a boy. There was no similar genetic abnormality in the family. The ectodermal dysplasia was of hidrotic types. The embryological findings account for the association between the ectodermal dysplasia and the medial dysraphia of the face.

Comparison of the cognitive palatability assessment protocol and the two-pan test for use in assessing palatability of two similar foods in dogs.

OBJECTIVE: To compare preferences of dogs for 2 similar foods by use of 2 distinct methods (the cognitive palatability assessment protocol [CPAP] and the 2-pan test). ANIMALS: 13 Beagles. PROCEDURE: 6 dogs were trained in a 3-choice object-discrimination-learning task in which their nonpreferred objects were associated with a reward of a lamb-based or chicken-based food. The number of choices for each object was used to determine food preferences. Preference of the same foods was also assessed by use of a 2-pan test in which all 13 dogs were provided the 2 foods in identical bowls. The amount of each food consumed in 10 minutes was used to determine food preference. RESULTS: All dogs had a noticeable preference for the chicken-based food during the CPAP. Once established, preferences remained consistent and were not affected by satiety. The 2-pan test identified a preference for the chicken-based food in dogs with previous exposure to the food but only a weak and nonsignificant preference for the same food in dogs without previous exposure. Food preferences in the 2-pan test varied considerably. Total food consumption and the ability to detect a preference were reduced when dogs were fed prior to testing. CONCLUSIONS AND CLINICAL RELEVANCE: The CPAP provides a reliable measure of food preference that requires few test subjects. The 2-pan test reveals similar preferences but with variability in data that requires larger numbers of subjects and is susceptible to effects from prior exposure and feeding of the test foods to the subjects.

Image analysis of lateral velopharyngeal closure in repaired cleft palates and normal palates.

We have undertaken the design and testing of a system for making measurements of velopharyngeal function from lateral videofluoroscopic images based upon standard equipment found in any cleft clinic. The uncertainties in the measurements have been found to be acceptably low and, in conjunction with other measurement techniques, the system has made a valuable contribution to the assessment of velopharyngeal function. Additional measurements using this system are presently being developed.
