Filter by:The purpose of this study is to compare types of and risk factors for cleft lip and palate in a Guatemalan population to a United States population.
The 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.
The purpose of this study is to investigate the change in intraocular pressure according to the neck extension during palatoplasty in pediatric patients.
This is a prospective observational cohort study of consecutive patients with cleft lip and palate deformity undergoing cleft repair at the Institute of Mother and Child in Warsaw. Cleft morphology will be captured with photo and intraoral camera before routine surgery at around 8 months. Furthermore, wound healing at 3 months postoperative will be assessed.
Trainees' experience in cleft surgery is limited due to the high-risk nature of the surgery and centralization of cleft care. Simulations allow trainees to learn complex surgical skills whilst ensuring patient safety. Existing cleft surgical simulators are over-simplified or prohibitively expensive. We developed and tested a high-fidelity yet cost-effective simulator for cleft palate repair. Skeletal elements were obtained through high-resolution scanning of a pathologic specimen, 3D printed and then molded in plastic. Soft tissue components were formed through molding layers of silicone. 26 UK specialty trainees performed a vomerine mucosal flap and intra-velar veloplasty in a one-hour workshop. Pre- and post-simulation questionnaires assessing cleft knowledge and surgical confidence were compared for statistical significance.
Observational study about children with cleft palate from surgery to pre-adolescence :Description of language development and hearing profile.
to study the benefical audiological and/or otological effect by mordified restoration of tensor veli palatini in cleft palate repair compared to traditional Langenbeck's repair and merely levator veli palatini restoration.
: Cleft palate is a congenital deformity caused by abnormal facial development during intra-uterine life. Worldwide, the prevalence of cleft lip/palate is about 1:1000 live births. The levator vela palatini muscles are malpositioned sagittally, running postero-anteriorly and inserted onto the posterior edge of the hard palate in cleft palate patients . This configuration prevents the muscle from exerting its upward, backward, and lateral pull. Various modalities have been described with major refinements over the past 30 years. Gradually, cleft surgeons began to appreciate the importance of dissection and retro-positioning of the levator muscle on improving speech outcomes. Furlow was the first to describe the palatoplasty technique, in which the levator muscle is dissected and freely released from its abnormal position and retro-positioned in a Z-plasty lengthening technique without dissection on the hard palate. However , among the problems that have been raised concerning the Furlow palatoplasty is the limitation of the procedure in wide clefts. Furthermore, the possibility of higher fistula rate associated with the technique. These considerations have led to modified palatal lengthening by buccinator myomucosal flaps which is this study working on.
Patients treated with Maxillofacial Prosthesis have loss of maxillary and/or mandibular substances. Few data are available on quality of life of these patients and its association with some of their socio-demographic, medical and clinical characteristics.
Objective: 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.
