Primary Palatoplasty in Pediatric Patients - A Retrospective Review of Surgical Outcomes
Cleft LipCleft PalateChildren who are born with cleft palate need surgery in order to correct the problem. The surgery is needed because the defect allows food to leak into the nose. It also causes the patient to be unable to speak correctly, producing a problematic nasal sound. Sometimes the first surgery does not completely correct the problem and a second surgery is needed. Looking at the records of patients who have had corrective surgeries done in the past would allow the surgeons to improve their success rate and reduce the need for secondary surgeries. It would also create greater patient safety and reduce cost for families.
Estimation of the Carrier Frequency and Incidence of Smith-Lemli-Opitz Syndrome in African Americans...
Smith-Lemli-Opitz SyndromeRSH/Smith-Lemli-Opitz syndrome (SLOS) is one that causes mental retardation. It is common in the Caucasian population but rare in African American and African black populations. It has been shown that SLOS is caused by a specific defect in DHCR7, an enzyme used in cholesterol metabolism. Studies have already been done to determine the frequency of the SLOS-causing mutations in various geographic Caucasian populations. This study will investigate the frequency of the DHCR7 mutations in the African American population. If the frequency observed suggests that SLOS cases are not being identified in this ethnic group, the study will provide the rationale for future studies to identify these patients. The sample size will be 1,600. The study population will consist of archived biological specimens in the form of newborn screening blood spots from two newborn screening centers, one in Maryland and one in Pennsylvania. Subjects will be of African American ethnicity, including blacks of African, Caribbean, and Central American descent. Genomic DNA will be extracted from blood spots and screened for the six common SLOS mutations. If SLOS syndrome is found, followup will be attempted for the Maryland samples (the Pennsylvania samples will be totally anonymous).
Study of Smith-Lemli-Opitz Syndrome
Smith-Lemli-Opitz SyndromeSmith-Lemli-Opitz Syndrome (SLOS) is a genetic disorder (autosomal recessive) caused by an abnormality in the production of cholesterol. The disorder can occur in both a "mild" or "severe" form. SLOS is associated with multiple birth defects and mental retardation. Some of the birth defects include; abnormal facial features, poor muscle tone, poor growth, shortened life span, and abnormalities of the heart, lungs, brain, gastrointestinal tract, limbs, genitalia, and kidneys. There is no known cure for SLOS but recently patients have been treated with increased amounts of cholesterol in their diet. The cholesterol in a persons diet is unable to correct the abnormalities in the patient's organs, but researchers hope it will improve growth failure and mental retardation. This study was developed to answer questions about the causes and complications of SLOS, as well as the effectiveness of cholesterol treatment. The study will enroll patients diagnosed with SLOS, and their mothers. The objectives of the study will be to address the following questions: <TAB> What is the prognosis / natural history of the demyelination in the nervous system of patients with SLOS? <TAB> Do patients with SLOS have other problems concerning the function of their endocrine systems? <TAB>What are the genetic make-ups of patients with SLOS? <TAB>Can further studies of cholesterol metabolism and genetic testing, using SLOS fibroblasts, increase the understanding of SLOS?<TAB>
Relational Development in Children With Cleft Lips and Palates: Influence of the Waiting Period...
Cleft PalateThe treatment of patients suffering from cleft lip(s) with or without a cleft palate (CL/P) is multidisciplinary. The careful consideration of concerned families during the repetitive appointments required by these treatments show the importance of the psychological context and of the harmonious structuring of the parents-child relationships on the child's development. Yet the birth of a child affected by CL/P is a particularly stressing and traumatising event for the parents. The investigators' prospective, multidisciplinary and multi-centred research project aims to assess the psychological perceptions of parents of children affected by CL/P over the year following the birth and analyse the child's degree of psychological suffering as well as the parents-child relationships. The time of the first surgical intervention varies amongst the treatment centres. The investigators listed four centres that intervene at different times according to the more or less long waiting times between the child's birth and this first surgical intervention. The results obtained for each group will be compared to one another and according to two sub-groups: parents who found out about the CL/P through embryo diagnosis and those who found out at their child's birth. The mental and psychological dimension due to the malformation and its correction will be analysed in the parents group (importance of the prenatal diagnosis, relational development with the child, self-esteem, quality of life) but also in the child (likely distress and withdrawal symptoms).
Using of Acellular Dermal Matrix in Cleft Palatal Fistula and Compare With Use of Conchal Cartolage...
Cleft PalateThe fact that still exist is which method for repairing of secondary cleft palatal fistula is the best. This study will have shown whether using of Acellular dermal Matrix decreased the fistula formation versus using Conchal Cartilage during secondary fistula. Among studies that published, they have not consensus for using acellular dermal matrix. Most of the questions are about cost effectiveness, time that surgery and rehabilitation need and patient risk ( risk of transmission disease from other human tissue )
Feasibility and Performance of Virtual Software for Virtual Bone Graft Planning in Cleft Patients...
Cleft Palate ChildrenObjective: The investigators aim to compare the licensed Brainlab Iplan® software, considered the gold standard, to the 3D slicers and Blender freeware for the segmentation of the unilateral cleft defect, as well as the creation of individual 3D template for development of the bone graft. Study design Retrospective, pilot study Patients presenting at the division of maxillofacial surgery at the AZ Sint-Jan Brugge-Oostende av (Belgium) or the 1st department of pediatrics at the USemmelweis (Hungary) for bone graft surgery of the unilateral cleft receive a complete routine work-up, including a cone-beam CT (CBCT). A single surgeon will run all the virtual planning steps with both the licensed software and the freeware. Timing of the four major steps will be measured with a digital chronometer (http://www.online-stopwatch.com/download-stopwatch/). Ten children, 5 Belgian patients and 5 Hungarian patients, that already had a work-up and surgery for a unilateral cleft requiring a bone graft, will be planned. This based on the preoperative CBCT that is already present, by using both the licensed software and free software. The investigator will register patients' age, gender and cleft size and register the required time to complete the different planning steps, as well as list the number of actions to complete the planning, and the occurrence of software bugs. In addition, the learning effect will be examined through comparison of the different cases planned by the same surgeon. All patients will be planned twice with an interval of two weeks in order to measure intra-observer reliability. Moreover, a second surgeon will also plan the 10 cases to measure inter-observer reliability. Main study endpoints The investigators hypothesize that the licensed software is more user-friendly, ensuring a significant shorter overall treatment planning time to create a model for accurate bone transfer from the iliac crest to the jawbone.

Optic Nerve Sheath Diameter Measurement in Cleft Palate Repair
Cleft PalateThe aim of this study is to evaluate the effect of the Boyle-Davis mouth opener, which is routinely used in cleft palate surgery, on intracranial pressure by USG-guided optic nerve sheath diameter measurement, which is a non-invasive method with proven effectiveness and reliability in recent years.
Postoperative Analgesic Effects of Infraorbital Nerve Block in Cleft Palate Surgery
PainPostoperativeCleft palate repair is a common surgery in children.. As such children with cleft palate tend to have a compromised airway due to associated congenital anomalies like Pierre Robin syndrome, Treacher Collins syndrome etc. After surgical correction of cleft palate, they are more prone to develop post-operative respiratory difficulty due to narrowed airway, increased secretion, pain and sedation caused by opioids. Hence, regional block, using local anesthetics, becomes a good option in this surgery. The supremacy of bilateral infraorital block using levo bupivacaine over intravenous fentanyl as well as over peri-incisional infiltration in has been shown .Levobupivacaine was developed after Ropivaciane was noted to be associated with less no of adverse events.. Ropivacaine has been used for peripheral block in children for surgical pain. Though the use of Levobupivacaine in regional blocks in facial surgeries has been well established, studies are still needed to establish its supremacy over Ropivacaine in cleft palate surgeries
