View clinical trials related to Cleft Lip and Palate.
Filter by:Bilateral cleft lip and palate neonates will be randomly assigned to one of two groups: (gp1 presurgical Naso-alveolar molding (NAM) using Grayson method, gp 2 computer aided design NAM (CAD/NAM). The aim of the study is to compare between short term clinical effects of both interventions as regards alveolar alignment, nasal esthetics and interlabial gap.
The aim of this trial is to figure out the efficiency of modified Grayson NAM on parents' satisfaction, nasal esthetics, interlabial gap and maxillary arch changes. NAM might improve and facilitate the surgical procedure after lip closure. This might decrease the need of further interventions to improve esthetics and function of CLP patients. This trial will help the patients and practitioners in taking the decision of inclusion of NAM in the CLP treatment protocol as a mandatory step or skip a useless procedure with all of its burden.
Patients with cleft lip and palate frequently develop Class III (Cl III) malocclusions or underbites following early cleft repair surgeries. This clinical trial compares the current standard of care for treating the Cl III malocclusion, orthognathic (jaw) surgery after pubertal growth (16-21 years), with an alternative orthopedic approach to protract the maxilla during adolescence (11-14 years). At Children's Hospital Los Angeles(CHLA), early adolescents with cleft lip and palate and Cl III malocclusion are offered an alternative non-surgical approach to correct the malocclusion called "maxillary protraction". Prior to age 14, the maxillary sutures have not fused and can be mobilized by alternating weekly expansion and constriction with a rapid palatal expander (RPE), thereby allowing the upper jaw (maxilla) to be pulled forward (protracted) to correct the underbite. This prospective parallel cohort study will assess the patients undergoing treatment for the Cl III malocclusion by either orthognathic surgery or maxillary protraction at four data collection time points during treatment. The data includes digitized study models, photographs and radiographs, quality of life surveys (SF12, YQOL), parent surveys (ASEBA), treatment cost, periodontal measurements and treatment complications. The study design is a descriptive cohort study that examines the success of treatment (% not requiring a second surgery), the dental and skeletal changes associated with treatment, the stability of treatment and the behavioural/adaptive factors (ASEBA) that contribute to success and lack of success for each treatment. The primary trial will be conducted at Children's Hospital Los Angeles and a pilot study to confirm translation to different settings will be conducted at Seattle Children's Hospital.
The aim of this study is to perform the bone tissue engineering to reconstruct the alveolar bone defect in cleft lip and palate patients using mesenchymal stem cells from deciduous dental pulp associated with a collagen and hydroxyapatite biomaterial (Geistlich Bio-Oss®) through prospective qualitative and quantitative analysis of bone neoformation.
Cleft lip and palate patients normally present with a sunken face due to collapse in the middle part of the face and inability of the upper and lower teeth to meet during chewing. This situation constitutes a serious aesthetic and mastication problem. A single surgical operation known as orthognathic surgery was traditionally performed to move the upper jaw forward to a more normal position and allow chewing function to be regained. However, due to scar tissue from the original surgical repair of the cleft palate, this procedure is known to be unstable causing bone to rapidly go back to its original position. A new concept of moving the upper jaw bone gradually by 1mm per day using a special device attached to the bone called distraction osteogenesis was established in 1996. Animal studies have shown that this technique can produce stable results with minimal relapse. The feasibility of correcting cleft deformities by gradual distraction has been confirmed by our own clinical studies. The aim of this study (which is the first of its kind) is to conduct a prospective randomized controlled study and compare the treatment outcomes of the current standard (orthognathic surgery) with distraction osteogenesis (gradual bone movement). The objectives focus on four aspects: morbidity, stability, speech function and psychological impact. The results from this study will clarify several clinical dilemmas in decision making when choosing whether to use orthognathic surgery or distraction osteogenesis in the treatment of cleft lip and palate patients. In addition, it will also inform our multidisciplinary research team to improve the total care of the cleft lip and palate patients. Gradual bone distraction of the midface in cleft palate patients is more stable, less detrimental to speech, and no more troublesome to the patient than conventional osteotomy and bone transposition (orthognathic surgery).
The purpose of this study is to determine whether secondary (revision) surgery to the lip in patients with cleft lip and palate is effective in improving lip function and appearance.
