Filter by:Investigators aim to evaluate the influence of cleft surgery on the tissue microcirculation of the palate with a non-invasive measurement.
Early neonatal cheiloplasty is modified surgery protocol applied in the first week of newborn's life used for treating orofacial cleft patients. This prospective study analyzes the effects of early neonatal cheiloplasty on the growth and development of maxilla and palate during the observed period of one year.
Using separate prospective cohorts of patients who have lip revision and lip repair surgery, the objective of this clinical trial is to both qualitatively and quantitatively assess how surgeons integrate the objective measures and visual aids of the Intervention with the systematic subjective assessment in order to determine decisions surgery.
Despite significant progress made in identification on numerous genes and gene pathways critical for craniofacial development, several approaches, ie mutation screening of specific candidates, association studies and even genome-wide scans have largely failed to reveal the molecular basis of NS human clefting
Evaluation of the effect of botulinum toxin type-A injection prior to surgical correction of complete unilateral cleftlip repair by modified millard cheiloplasty
We seek to compare biochemically and histologically the nasal cartilage and ear in the newborn cleft lip and slot carrier in order to improve the quality of care and patient comfort after surgery of cheilorhinoplasty which is the primary treatment slots . The concentration of hyaluronic acid as well as in type 1 collagen and 3 are assayed by immunohistochemistry and study of mRNA and then they are compared according to the type of cartilage. This comparison is done on nasal cartilage samples and atrial newborns holders of cleft lip and operated in the neonatal period. Given the difficulty and constraint of time it takes to reach the 20 subjects of our study , we will also add to our population the stillborn babies before 25SA and newborns who die before the age of 28 days and having had an autopsy.
Le Fort I osteotomy is often used in orthognathic surgery for patients to solve midface retrusion. It is known that post-surgical stability of Le Fort I osteotomy can be influenced by single jaw or bimaxillary procedures, fixation techniques or interpositional grafting. In patients with cleft lip and palate, the postoperative instability of Le Fort I osteotomy can be even worse due to scar tissue resulted from palate surgery. Segmental LeFort I osteotomy is another useful surgical modifications that can be easily done through the alveolar cleft. It is performed to allow the correction of differences in the occlusal planes, correction of transverse discrepancy or to facilitate an optimal occlusion. The most important benefits is that the alveolar cleft in patients who have not had alveolar bone graft surgery or failed to have successful result can be narrow down or even closed by approximation of two separating alveolar segments. However, there are limited previous studies comparing the stability of segmental versus one-piece Le Fort I osteotomy especially in patients with cleft. It is our aim to investigate whether one-piece Le Fort I osteotomy or segmental Le Fort I osteotomy can provide a better stability after surgery.
The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.
Botulinum toxin type A (Botox; Allergan, Inc., Irvine, Calif) is widely used for facial rejuvenation and many other medical indications. It induces chemodenervation through its action on the presynaptic neuron, preventing release of acetylcholine, which leads to functional denervation of striated muscle for 2 to 6 months after injection. The use of botulinum toxin injection to reduce the facial scar is logical because this could reduce the tensile distracting force of the upper lip caused by the orbicularis oris muscle pull. Tollefson has demonstrate that botulinum toxin injection has decrease lip tension after primary lip repair in 3 children at 3-6 months of age The main aim of this randomized trial is to compare whether post-operative peri-surgical-injection of botulinum toxin into bilateral orbicularis oris muscles can improve scar formation for both primary and secondary cleft lip surgery.
The primary objective of this clinical trial is to assess the influence of orthognathic surgery on facial soft tissue, such as changes (volume, linear, angular) of facial hard and soft tissue, in three dimensions, so enabling the setup of 3D normative value tables.
