OBJECTIVE: The goal of this study was to gather information from mothers’ of children born with orofacial clefts (OFC) in order to more accurately describe their early feeding experiences, from the time of diagnosis through the first six months of life. METHODS: We surveyed mother’s whose babies with OFC were treated at Seattle Children’s Hospital (SCH) Craniofacial Clinic and were born on or after 1/1/2013 through 12/31/2016. Survey questions were geared toward understanding overall difficulty with feeding, access to supplies for feeding, and methods and duration of any breast milk feeding. RESULTS: Eighty-two percent of mothers wanted to exclusively breastfeed for the first 16 weeks prior to the OFC diagnosis, of which 79% attempted breastfeeding and 74% attempted any breast milk feeding. Donor milk was used in 18% of mothers and 41% supplemented with formula in the delivery hospital. The majority of women were knowledgeable about facts of breastfeeding and 41% reported they received information from a lactation specialist in their delivery hospital. The level of stress reported by mothers stayed relatively the same over first 4 weeks of life and dropped by 16 weeks. The majority of women who used a breast pump pumped for 0 to 20 minutes in first week and then 0 to 30 minutes between weeks 4 to 16. Thirty percent of mothers reported receiving information specifically from a craniofacial nurse and craniofacial pediatrician before delivery and 36% reported receiving information from a craniofacial nurse and craniofacial pediatrician after their birth hospital stay. CONCLUSION: Initial study results of feeding practices, knowledge of breast milk feeding, and feeding experiences of mothers with babies born with OFCs show that most mother’s intended to exclusively breastfeed prior to their birth and that the majority of women were reasonably informed about the benefits of breastfeeding. We also found that after the delivery of their child with an OFC more mothers reported having difficulty with feeding and wanted to provide breast milk longer than they were able to do so. Once the data collection is complete the survey data will be stratified for prenatal versus postnatal diagnosis and also when a breast pump was obtained. This information and additional data will be collected from a second phase of the study, which is a medical chart abstraction to look at the child’s demographics and growth chart data for the first six months of life.

Este trabalho teve como objetivo analisar os casos com fissura de palato submucosa (FPSM) acompanhados no HRAC/USP, no período de 1984 a 2004, verificando a distribuição destes casos de acordo com a idade e conduta adotada na consulta inicial e; se a conduta inicialmente adotada manteve-se ou necessitou ser reconsiderada. Foram analisados 1.260 prontuários de pacientes FPSM, sendo excluídos 175 que apresentavam quadros sindrômicos e, portanto, a amostra final constou de 1.085 pacientes, de ambos os gêneros e procedentes das diferentes regiões do país, os quais foram distribuídos em 5 grupos etários de acordo com idade na época da consulta inicial: menores de 3 anos, de 4 a 6 anos, de 7 a 12 anos, de 13 a 17 anos e acima de 18 anos. A análise evidenciou 557 (51,33%) casos com FPSM isolada e 528 (48,67%) com FPSM associada à fissura labial, sendo os mesmos analisados de acordo com a conduta inicial adotada: acompanhamento, fonoterapia, prótese de palato ou cirurgia, respeitando-se os grupos etários definidos. Após a análise dos casos com fissura de palato submucosa acompanhados no HRAC/USP, no período de 1984 a 2004, concluiu-se que: quanto à distribuição dos casos de acordo com a conduta definida na consulta inicial, na FPSM isolada predominou a indicação para cirurgia nas idades acima de 4 anos e acompanhamento nas idades abaixo de 3 anos e, na FPSM associada à fissura labial predominou a conduta acompanhamento; Quanto à manutenção ou reconsideração da conduta inicial, dos casos indicados para acompanhamento, na FPSM isolada, a maioria dos casos alterou a conduta para cirurgia e na FPSM associada à fissura labial, a maioria manteve a conduta inicial; daqueles indicados para fonoterapia, na FPSM isolada, predominou manter a conduta inicial nas idades menores de 3 anos e de 7 a 12 anos e alterar a conduta para cirurgia nas idades de 4 a 6 anos e de 13 a 17 anos e, nos casos com FPSM associada à fissura labial, a maioria manteve a conduta inicial; dos casos indicados para prótese de palato, na FPSM isolada, a maioria dos casos entre 4 e 6 anos alterou a conduta para cirurgia, houve equilíbrio entre manter a conduta inicial e alterar para cirurgia na faixa etária de 7 a 12 anos e houve manutenção da conduta inicial na faixa etária maior de 18 anos, não ocorrendo casos com FPSM associada à fissura labial, já, dos casos indicados para cirurgia, tanto na FPSM isolada quanto na FPSM e associada à fissura labial prevaleceu à conduta inicial. / This study analyzed the patients with submucous cleft palate (SMCP) assisted at HRAC/USP during the period 1984 to 2004, checking the distribution of these cases according to age range, approach adopted at the initial consultation, and if the approach initially adopted was maintained or reconsidered. A total of 1,260 records of patients with SMCP were analyzed; 175 were excluded due to the association with syndromes, leading to a final sample of 1,085 patients, of both genders and from different regions of the country, which were distributed into 5 age groups according to the age rage upon initial consultation: younger than 3 years, 4 to 6 years, 7 to 12 years, 13 to 17 years, and older than 18 years. The analysis revealed 557 (51.33%) cases with isolated SMCP and 528 (48.67%) cases with SMCP associated with cleft lip. These cases were analyzed according to the initial approach adopted: follow-up, speech therapy, speech prosthesis, or surgery, according to the aforementioned age groups. The following could be concluded: with regard to the initial approach, for patients with isolated SMCP, there was predominance of indication for surgery at the ages above 4 years and follow-up for patients younger than 3 years, whereas in cases with SMCP associated with cleft lip there was predominance of follow-up. Concerning the maintenance or reconsideration of the initial approach, among the cases with isolated SMCP indicated for follow-up, in most cases the approach was altered to surgery, whereas the initial approach was mostly maintained for individuals with SMCP associated with cleft lip. Among individuals with isolated SMCP with indication for speech therapy, there was predominance of maintenance of the initial approach for patients younger than 3 years and aged 7 to 12 years, with maintenance of the initial approach for patients aged 4 to 6 years and 13 to 17 years, with predominance of maintenance of the initial approach for patients with SMCP. In relation to the cases with isolated SMCP with indication for speech prosthesis, the approach was altered to surgery in most cases aged 4 to 6 years; there was similar proportion between maintaining the initial approach and altering to surgery at the age range 7 to 12 years; and the initial approach was maintained for patients older than 18 years; there were no cases of SMCP with cleft lip under this indication. Contrarily, among the cases with indication for surgery, the initial approach was maintained for individuals with both isolated SMCP and SMCP with cleft lip.

Os efeitos das cirurgias primárias sobre os arcos dentários vêm sendo objeto de estudo ao longo do tempo. O presente estudo se propõe a avaliar a relação oclusal dos arcos dentários de pacientes com fissura transforame incisivo unilateral submetidos à cirurgia de lábio e palato mole no primeiro tempo e palato duro no segundo tempo por meio de modelos de estudo documentados em pacientes portadores de fissura transforame incisivo unilateral em uma fase mais tardia. Para a avaliação das arcadas utilizou-se o índice oclusal de Goslon (Mars et al 1987) em uma amostra de 42 modelos de gesso de pacientes com idade entre 15 e 19 anos que reparam o palato mole aos 6 meses e o palato duro aos 40 meses. O objetivo dos índices consiste em facilitar o prognóstico e a aplicação de protocolos terapêuticos no tratamento dos pacientes com fissuras de lábio e palato. Em relação aos resultados, a distribuição do Índice oclusal de Goslon foi 42,86% dos pacientes no grupo 1 (G1), 19,05% no grupo 2 (G2), 16,67% no grupo 3 (G3), 7,14% no grupo 4 (G4) e 14,29% no grupo (G5). Para os escores agrupados do índice de Goslon, 61,90 % dos pacientes foram classificados nos grupos 1 e 2 (G1+G2) demonstrando uma relação interarcos satisfatória e 21,43% foram categorizados nos grupos 4 e 5 (G4+G5), considerando uma pobre relação interarcos. / The purpose of this work was to evaluate the outcomes of the application of delayed hard palate closure treatment protocol on the dental arch on a sample of Brazilian patients aging 15 to 19 years old. The sample comprised 42 patients with UCLP, on the permanent dentition, aging 15 to 19 years old, treated with the referred protocol. The mean age of closure was 6 (±3.15) and 40 (±36.07) months for soft and hard palate respectively. Dental casts were obtained and analyzed by a single calibrated (kappa > .71) examiner. Dental arch relationships were accessed on the by applying the Goslon Yardstick, which has been proved to be a useful method for longitudinal assessment of dental arch relationship. The frequencies of each Goslon Yardstick score were described in order to evaluate long-term treatment results on these patients. The distribution of the cases into their assigned Goslon Yardstick scores showed 18 (42.86%) cases on group 1, 8 (19.05%) cases on group 2, 7 (16.67%) cases on group 3, 3 (7.14%) cases on group 4 and 6 (14.29%) cases on group 5. In evaluating the results described, it was possible to conclude that long-term results of delayed hard palate closure treatment protocol for UCLP regarding dental arch relationships were satisfactory on the studied sample: 61.9% of the patients showed excellent or good arch relationship (G1+G2) while 21.43% were classified as having poor or very poor arch relationship (G4+G5).

Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients. Methods: The experimental group (EG) was composed of 25 patients with unilateral and complete cleft lip and palate (9 males and 15 females) with a mean age of 10.6 years. The control group (CG) comprised of 27 patients without cleft lip and palate (14 males and 13 females) with a mean age of 9.1 years. Dental models of the maxillary dental arch were obtained immediately preexpansion (T1) and 6 months post-expansion (T2) at the time of appliance removal. Digital dental models were obtained using the 3Shape R700 3D laser scanner (3Shape A/S, Copenhagen, Denmark). Transversal widths, arch perimeter, arch length, palatal depth, palatal volume, canine and posterior tooth inclination were digitally measured. Paired t-test was used to perform interphase comparisons and independent t-test to perform intergroup comparisons (p<0.05). Results: In the experimental group, the expansion produced a ignificant increase of all maxillary transverse measurements, palatal volume, arch perimeter and palatal depth while decreased the arch length. RME caused a buccal tip of posterior teeth in patients with UCLP. No differences were observed between experimental and control groups for all the measurements performed except for the intermolar distance (6-6), which showed a greater increase in patients with cleft. Conclusion: Rapid maxillary expansion showed similar dentoalveolar effects in children with UCLP and without oral clefts. / Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients.

Os objetivos do presente estudo foram: 1) mensurar e descrever as medidas de extensão e espessura do véu palatino e da profundidade da nasofaringe em indivíduos com fissura transforame unilateral operada (FTU) que apresentavam disfunção velofaríngea (DVF); 2) calcular e descrever a razão entre a profundidade da nasofaringe e a extensão do véu palatino; 3) comparar as medidas encontradas para os indivíduos deste estudo com as normas descritas por SUBTELNY (1957); 4) comparar as medidas encontradas entre os sexos masculino e feminino; 5) comparar as medidas encontradas para os indivíduos que receberam palatoplastia com procedimento de Furlow (FW) com as medidas daqueles que receberam procedimento de Von Langenbeck (VL); 6) correlacionar as medidas encontradas com as idades dos indivíduos. A casuística foi constituída de 30 indivíduos com FTU e DVF, sendo 15 meninas e 15 meninos, com média de idade de 6 anos e 11 meses. Desses 30, 10 tiveram o palato operado pela técnica de FW e 20 pela de VL, entre as idades de 9 e 18 meses. Para definição da conduta para correção da DVF, todos os indivíduos foram submetidos ao exame de videofluoroscopia. Uma imagem em tomada lateral do MVF em repouso fisiológico foi selecionada e editada em um DVD para análise e mensuração das estruturas velofaríngeas de interesse. Três fonoaudiólogas experientes em videofluoroscopia realizaram as mensurações. Os resultados indicaram média de 27,4 mm para as medidas de extensão do véu palatino, de 9,7 mm para as de espessura do véu palatino, de 22,7 mm para as de profundidade da nasofaringe e de 0,86 para a razão entre a profundidade da nasofaringe e a extensão do véu palatino. Comparando os resultados do presente estudo com os de Subtelny (1957) diferença significante foi encontrada para as medidas da espessura do véu palatino, da profundidade da nasofaringe e da razão entre a profundidade da nasofaringe e a extensão do véu palatino. Os resultados também demonstraram diferença significante entre a média das medidas de extensão do véu palatino nos sexos masculino e feminino. Não houve diferença significante entre a média das medidas das estruturas avaliadas para os indivíduos operados pela técnica de FW nem pelos operados pela VL. Não houve correlação significante entre a variável idade e as medidas obtidas. / The objectives of the present study were: 1) to measure and to describe length and thickness of the velum and depth of nasopharynx for individuals with unilateral operated cleft lip and palate (UCLP) with velopharyngeal dysfunction (VPD); 2) to calculate and describe the depth of nasopharynx to velar length ratio (D/L); 3) to compare measures found for the individuals in this study with the norms described by Subtelny (1957) for normal individuals; 4) to compare the measures between males and females; 5) to compare the measures between individuals who received palatoplasty with the Furlow (FW) procedure to those who received the Von Langenbeck (VL) procedure; 6) correlate measures between different ages. The sample included 30 individuals with UCLP and VPD, 15 girls and 15 boys, with mean age of 6y11m. Ten individuals had palatoplasty with FW procedure and 20 with VL, between the ages of 9 and 18 months. For identifying best procedure for correcting VPD all individuals were submitted to videofluoroscopy assessment. A lateral view of the velopharyngeal mechanism during rest was selected and edited into a DVD, for analysis and measurement of the velopharyngeal structures of interest. Three speech-language pathologists experienced in videofluoroscopic assessment obtained all measures studied. The results revealed a mean velar length of 27.4 mm; mean velar thickness of 9.7 mm; mean depth of nasopharynx of 22.7 mm; D/L of 0.86. Comparing these results to Subtelny\'s (1957) a significant difference was found for measures of velar thickness, depth of nasopharynx velar length and D/L. Significant difference was found between males and females only for velar length. No significant differences were found between different techniques for palatoplasty. There was no significant correlation between age and the measurements obtained.
