For this select group of patients with immature skeleton, rhBMP-2 therapy resulted in satisfactory bone healing and reduced morbidity compared with traditional iliac crest bone grafting.
The amount of formed bone in the periosteoplasty group was insufficient. There was no difference among the bone graft and rhBMP-2 therapy considering the parameters analyzed.
Background. To reduce morbidity to cleft patients, new approaches have been developed and here, we report for the first time the use of deciduous dental pulp stem cells (DDPSC) associated with a hydroxyapatite-collagen sponge (Bio-Oss Collagen® 250 mg, Geistlich) for closing alveolar defects during secondary dental eruption, further comparing these results to historical controls. Methods. Six patients, aged 8 to 12, were selected. Autologous DDPSC were isolated from each patient, then associated with the biomaterial and this bone tissue engineered set was used to fill the alveolar defect. Computed tomography was performed to assess both preoperative and 6- and 12-month postoperative outcomes. Overall morbidity was recorded. Historical controls consisted of sixteen patients previously selected and randomly assigned to group one (rhBMP-2) or group two (iliac crest bone graft). Results. DDPSC could be isolated and characterized as mesenchymal stem cells. Progressive alveolar bone union has occurred in all patients. Similarly to group two 75.4%, SD±4.0, p>0.999, but statistically different from group one (59.6%, SD±9.9, p=0.001), completion of the defect with 75.6% (SD±4.8) of bone filling was detected 6 months postoperatively. Dental eruption routinely occurred in 66.7% of patients. No complications were detected, in comparison to significant swelling in 37.5% of group one patients and significant donor site pain in 87.5% of group two. Conclusion. For this selected group of patients, DDPSC therapy resulted in satisfactory bone healing with excellent feasibility and safety, which adds significantly to the prospect of stem cell use in clinical settings.

Avaliação comparativa e evolutiva dos protocolos de atendimento dos pacientes fissuradosComparative and evolutive evaluation of attendance protocols of patients with clef lip and palate RESUMO Introdução: Os protocolos de atendimento multiprofissional são tentativas para obtenção dos melhores resultados estéticos e funcionais possíveis no tratamento dos pacientes fissurados. Objetivo: Este estudo tem por objetivo analisar comparativamente os resultados obtidos no primeiro e no segundo ano após a implantação do protocolo de atendimento multiprofissional, buscando evidenciar as diferenças significativas encontradas após maior tempo de experiên-cia desta padronização terapêutica. Método: Estudo prospectivo, 102 pacientes portadores de fissura labiopalatina foram operados no período de 12 meses, conforme protocolo pré-determinado. Os resultados obtidos foram analisados e comparados com os encontrados no ano de 2008. Resultados: O número de pacientes atendidos e cirurgias realizadas aumentou 13%. Oito categorias cirúrgicas foram relatadas, palatoplastia (35,18%) foi a mais realizada, seguida por queiloplastia (unilateral e bilateral), mantendo o mesmo padrão de distribuição. Os procedimentos secundários persistiram com altos índices (aproximadamente 30%), porém o número de complicações diminuiu (nenhuma fístula). Conclusão: A padronização do tratamento dos pacientes fissurados demonstrou melhora nos resultados encontrados, mesmo em curto período de tempo. Entretanto, análises sistemáticas dos anos seguintes serão realizadas com o intuito de obter melhores parâmetros para o tratamento ideal.Descritores: Fissura palatina. Fenda labial.

SUMMARY Introduction: Multidisciplinary Attendance Protocols are attempts for attainment of the best aesthetic and functional results in the treatment of the patients with cleft lip and palate. Objectives: The present study aims to realize a comparative analysis of the outcomes found in the first and second years after the institution of the multidisciplinary attendance protocol. Methods: Prospective study, 102 patients with cleft lip and palate were operated in a 12 months period, submitted to a treatment following a pre-determined protocol. The outcomes were analyzed e compared with those results found in 2008. Results: The number of patients assisted and procedures increased 13%. Eight surgical categories were related, palate repair (35.18%) was the most utilized one, followed by lip repair (unilateral and bilateral), keeping the same distribution pattern. Secondary procedures had persisted with high rates (approximately 30%), however the number of complications decreased (no fistulae). Conclusion: The standardization of the treatment demonstrated improvement in the found results, even in short period of time. However, systematic analysis of the following years will be realized with intention to get better parameters for the ideal treatment.Descriptors: Cleft palate. Cleft lip. Practice guideline.
