OBJECTIVE To evaluate the effect of infant orthopedics (IO) on facial appearance of 54 patients with unilateral cleft lip and palate (UCLP), aged 4 and 6 years. DESIGN Prospective two-arm randomized controlled clinical trial in three Cleft Palate Centers in the Netherlands (Dutchcleft-trial). INTERVENTIONS Patients were divided randomly into two groups.(More)
Over the past decade, three-dimensional (3-D) imaging has been developed to such a stage of perfection and to such a level of interactive selective imaging of specific anatomic and pathologic structures that craniofacial surgeons can now use this technique effectively in the planning of complicated reconstructive surgery. In addition, modeling techniques(More)
Children with syndromal craniofacial synostosis have a high risk for obstructive sleep apnea syndrome. Early diagnosis and treatment can relieve symptoms and morbidity. Little is known about the development and natural history of obstructive sleep apnea syndrome through life. The aim of this study was to investigate our experience of clinical history and(More)
The aesthetic results of craniofacial surgery for trigonocephaly were evaluated by a panel assessment using a scoring system based on deformities typical for this type of craniosynostosis. In this retrospective study pre-and postoperative photographs of 45 patients were scored for items typical for trigonocephaly: shape of the forehead, hypotelorism, and(More)
One aim of this study was to assess right-left differences in the volume of masticatory muscles in controls so as to be able to distinguish between normal variations and pathological differences. The other aim was to compare the masticatory muscle volume of the nonaffected side of hemifacial microsomia patients with the smaller side of controls so as to(More)
A craniofacial team is functioning since 15 years in Sophia's Children Hospital and Dijkzigt Hospital. An intensive-care unit and a anaesthesist specialised in children is imperative for proper functioning of the team. An overview of the most common Craniofacial malformation is given, the operative technique of craniosynostosis described and the(More)
Isolated synostosis of the frontosphenoidal suture is very rare and difficult to diagnose. Little has been reported on the clinical presentation and fetal development of this suture. To understand the development of the frontosphenoidal suture and the outcome of its synostosis. We studied the normal fetal development of the frontosphenoidal suture in dry(More)
The aim of this study was to evaluate mandibular distraction therapy by three-dimensional (3-D) computed tomography (CT) imaging so as to be able to improve the treatment results. The study group consisted of eight children (3 male and 5 female) with hemifacial microsomia. For each child, CT scans of the head were available (Pro Speed S Fast Spiral scanner;(More)
An alternative method for fixation of soft tissue in the face, such as the medial and lateral canthus and free flaps, and for reconstruction of the nasolabial fold is presented, using the micro Mitek Anchor. The insertion of a bone anchor requires only a limited dissection, and the point of insertion can be determined accurately. These advantages are(More)
BACKGROUND Analgesic acetaminophen (INN, paracetamol) plasma concentrations after major surgery in neonates and infants have not yet been established in the literature. We therefore conducted a study in our intensive care unit. METHODS Forty children, mean (standard deviation) age, 10.3 (2.3) months, received 20 mg/kg acetaminophen either orally (n = 20)(More)
