Active clinical trials for "Congenital Abnormalities"

In this study, The investigators aims to evaluate the efficacy and safety of topical hyaluronic acid nanoparticles as a novel nanodermatological tool in periocular rejuvenation as a replacement approach of invasive dermal filler injections.

Research studies continues to attempt testing modifications to refine the treatment protocols through computer assisted design or computer-generated surgical Wafer splints, have greatly revolutionized the incorporation of digital imaging and 3D design in Orthognathic surgery. Integrating computer guided technology in orthognathic surgery aims to to simplify workup and reduce surgical errors, eliminate occlusal discrepancy, increase the realignment accuracy of the distal segments according to the preoperative plan. Implementing a waferless technique raised the question of efficiency versus the use of occlusal wafers and whether it has a significant measurable effect on the surgical outcome and objectives. Rationale for conducting this study is to assess the difference between the effect of computer guided waferless technique and computer guided technique with occlusal wafer on accuracy of postoperative occlusion and condylar position. .

The objectives of this study and registry are to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty. Management may include interventional therapy (with endovascular procedures, neurosurgery, or radiotherapy, alone or in combination) or conservative management. The trial has been designed to test a) whether medical management or interventional therapy will reduce the risk of death or debilitating stroke (due to hemorrhage or infarction) by an absolute magnitude of about 15% (over 10 years) for unruptured AVMs (from 30% to 15%); and, b) to test if endovascular treatment can improve the safety and efficacy of surgery or radiation therapy by at least 10% (80% to 90%). As for the nested trial on the role of embolization in the treatment of Brain AVMs by other means: the pre-surgical or pre-radiosurgery embolization of cerebral AVMs can decrease the number of treatment failures from 20% to 10%. In addition,embolization of cerebral AVMs can be accomplished with an acceptable risk, defined as permanent disabling neurological complications of 8%.

To evaluate the efficacy of Rapamycin in extended cervicofacial lymphatic malformations in pediatric patients. Rapamycin is administered oral for a 6 month period. The success rate is determined by volume reduction superior to 1/5e of the initial volume measured by MRI, impact on QOL and reduction of bleeding in case of mucosal involvement.

This study evaluates the efficacy of the AuryzoN devices in the ear and nose reconstruction surgeries, both in terms of operative time and overall quality of reconstruction. Research participants will undergo reconstruction either using the AuryzoN device or through current methods (traditional manual processing) at the discretion of their surgeon prior to the start of surgery.

KHE and TA are rare tumors and some of the cases may lead to life-threatening complications including Kasabach-Merritt Phenomenon. Typically treated with steroids and vincristine, a majority of the cases do not have good prognosis. Complex vascular malformations are always managed by surgery,sclerotherapy and embolization therapy. While many of the cases still lead to complications such as disfigurement, chronic pain, recurrent infections, coagulopathies. Different medical centers are exploring new therapy for these tough problems. This study is plotted to determine the efficacy and safety of rapamycin monotherapy in KHE/TA and complex vascular malformations in pediatric patients.

This clinical trial is to verify the safety and effectiveness of the Non-adhesive Liquid Embolic System(NALES) produced by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd. in the process of clinical use to support the application of the National Medical Products Administration ( NMPA) product registration approval.

This study evaluates the safety and efficacy of PTX-022 (sirolimus) Topical Gel 3.9% w/w in the treatment of Microcystic Lymphatic Malformations. The participant will receive 3 months of PTX-022 treatment by the end of the study.

Low-level laser therapy (LLLT) is a well-studied technique that has been shown to improve recovery time and reduce pain and swelling in patients undergoing surgery, including orthognathic surgery, and has no known negative effects. This study will use two groups with patients randomly assigned to either the study group, receiving LLLT, or one receiving a placebo treatment, after they have lower jaw surgery. Measurements will be taken at 24 hours, 1 week, 2 week, 3 week, 4 week, 5 week, and 6 week post-op exams to check pain, swelling and nerve function, and the two groups will be compared to see if the LLLT group has any difference

In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.
