“…14 The Anatomical Subunit Approximation for unilateral cleft lip repair was described in 2005 15 and has been characterized as a "hybrid" technique. 12 The design includes multiple landmarks with the intention of approximating incisions along the borders of anatomical subunits. 15 Although the technique has gained popularity, 16 the experience using this approach has yet to be described by other surgeons.…”

“…3,4 Millard's rotation advancement 5 and its modifications [6][7][8] involve a "cut-as-you-go" approach that can be prone to surgeon ability and experience and has been criticized for producing short lips when used for wide clefts. [9][10][11] The TennisonRandall repair is more geometric and is thought to be easier to learn 12 and more suitable for wide clefts 13 ; however, the resultant scar inevitably crosses natural contours. 14 The Anatomical Subunit Approximation for unilateral cleft lip repair was described in 2005 15 and has been characterized as a "hybrid" technique.…”

“…Since 1957, when the technique of rotation and advancement described by Ralph Millard, the most widely used for cleft lip correction 20 , to correct cleft nose deformity has become mandatory for the treatment. This procedure is useful to repair unilateral cleft lip, with reconstruction of the nasal floor, cupid bow and correction of columellar angle 21 .…”

Objetivo avaliar a mudança do ângulo columelar que ocorre após cirurgia de correção para fissura labial. Métodos o estudo foi observacional de caráter descritivo e de corte transversal. Foram avaliadas crianças no primeiro e segundo ano de vida, portadoras de fissura labial unilateral de ambos os sexos, que foram submetidas a cirurgia para correção da fissura. A pesquisa teve um total de 11 crianças participantes. Foi examinada a região nasal e lábio superior da criança e identificados os pontos antropométricos pronasal, subnasal e glabela. Em seguida, foi realizada fotografia para análise fotogramétrica. Foram realizadas fotos no preoperatório e cerca de 4 meses após a cirurgia. As imagens obtidas por fotogrametria foram avaliadas com o programa gráfico Image J,por meio de ferramentas de estudo angular. Resultados a média da medida dos ângulos no pré-operatório foi de 55,41 graus; a média no pós foi de 78,80 graus, percebendo-se uma aproximação ao plano vertical (p<0,0001). Pacientes com fissura lábio-palatina apresentaram variação de 32 graus quando comparadas as medidas pré e pós-operatórias, enquanto que nos pacientes com fissura pré-foramen incompleta e pré-foramen completa foram menores (0,75 e 25 graus respectivamente). Conclusão ocorre verticalização do ângulo columelar após cirurgia de correção da fissura labial. Os pacientes que apresentam maior modificação do ângulo são, justamente, aquelas que apresentam diagnóstico relacionado a deformidades mais complexas.

“…24,25,26,27 LeMesurier described the quadrangular flap and Tennison described the triangular flap as reliable methods for decreasing vertical lip contracture in unilateral cleft lip repair. 24,28 The primary advantage of geometric repair techniques for cleft lip is that they provide a reproducible method of lip repair.…”

The palatal shelves are initially separated by the developing tongue. Growth of the mandible is associated with inferior displacement of the tongue, which allows the palatal shelves to migrate superiorly and assume a horizontal orientation. The "shelf elevating force" that causes the upward motion of the shelves is believed to be mediated by a process involving mesenchymal proliferation and growth factor-induced changes in local extracellular matrix, including hydration of hyaluronic acid in the tips of the shelves. 5,6 If fetal development and mandibular growth do not proceed normally, the tongue does not descend and the palatal shelves cannot migrate superiorly and medially, despite the shelf elevating force. The resulting malformation can result in the Pierre Robin sequence (micrognathia, relative macroglossia, and U-shaped cleft palate) (Fig. 68.3). 7 Fig. 68.1 The developing human face at 5.5 weeks of gestational age. The primary palate is formed by fusion of the paired medial nasal prominences (a). The lateral nasal prominence (b) becomes the nasal ala. The maxillary process (c) forms the upper lip segments lateral to the philtrum. The mandibular process (d) becomes the mandible.This document was downloaded for personal use only.
