Surgically Assisted Rapid Maxillary Expansion: surgical and orthodontic aspects

The scope of this thesis is to shed more light, from a number of perspectives, on surgically assisted rapid maxillary expansion (SARME). The primary questions this thesis set out to answer were; ‘is there a difference in stability between bone-borne and tooth-borne distraction?’ and ‘can a relationship be found between segmental maxillary tipping, relapse, and the mode of distraction?’ Secondary questions were; ‘what is the influence of surgically assisted rapid maxillary expansion on the nasal airway and the nasalance of speech?’ and ‘what is the effect of surgically assisted rapid maxillary expansion on the upper facial appearance?’ The thesis is divided into five Parts. Part I consists of the general introduction, a review of the literature on SARME (Chapter 1). No consensus could be found regarding the surgical technique, the type of distractor used (tooth-borne or bone-borne), the existence, cause and amount of relapse, and whether or not overcorrection is necessary. Furthermore, relapse is widely recognized yet poorly explicated. A wide variety of techniques and methods to correct transverse maxillary hypoplasia is currently used without underlying scientific basis

Dental anomalies in craniofacial microsomia: A systematic review

Objective: To provide an overview on the prevalence and types of dental anomalies in patients with craniofacial microsomia (CFM). Eligibility criteria: Inclusion criteria were CFM and dental anomalies. The following data were extracted: number of patients, methodology, mean age, sex, affected side, severity of mandibular hypoplasia, dentition stage and dental

The potential for prevention of dementia across two decades: The prospective, population-based Rotterdam Study

Background: Cardiovascular factors and low education are important risk factors of dementia. We provide contemporary estimates of the proportion of dementia cases that could be prevented if modifiable risk factors were eliminated, i.e., population attributable risk (PAR). Furthermore, we studied whether the PAR has changed across the last two decades. Methods: We included 7,003 participants of the original cohort (starting in 1990) and 2,953 participants of the extended cohort (starting in 2000) of the Rotterdam Study. Both cohorts were followed for dementia until ten years after baseline. We calculated the PAR of overweight, hypertension, diabetes mellitus, cholesterol, smoking, and education. Additionally, we assessed the PAR of stroke, coronary heart disease, heart failure, and atrial fibrillation. We calculated the PAR for each risk factor separately and the combined PAR taking into account the interaction of risk factors. Results: During 57,996 person-years, 624 participants of the original cohort developed dementia, and during 26,177 person-years, 145 participants of the extended cohort developed dementia. The combined PAR in the original cohort was 0.23 (95 % CI, 0.05-0.62). The PAR in the extended cohort was slightly higher at 0.30 (95 % CI, 0.06-0.76). The combined PAR including cardiovascular diseases was 0.25 (95 % CI, 0.07-0.62) in the original cohort and 0.33 (95 % CI, 0.07-0.77) in the extended cohort. Conclusions: A substantial part of dementia cases could be prevented if modifiable risk factors would be eliminated. Although prevention and treatment options of cardiovascular risk factors and diseases have improved, the preventive potential for dementia has not declined over the last two decades

Parenting children with a cleft lip with or without palate or a visible infantile hemangioma: A cross-sectional study of distress and parenting stress

Objective: Parents of children with a medical condition and a visible difference can experience challenging situations. We evaluated distress and parenting stress in parents of children with a cleft lip with or without cleft palate (CL +/- P) or a visible infantile hemangioma (IH). Setting: This cross-sectional study took place in an academic medical hospital in Rotterdam, the Netherlands. Participants: Three-hundred nine parents (mean age = 40.30, 56.00% mothers) of children with CL +/- P and 91 parents (mean age = 36.40, 58.24% mothers) of children with IH. Main Outcome Measures: The Dutch version of the Parenting Stress Index - Short Form and the subscales Anxiety, Depression, and Hostility of the Symptom Checklist - 90. Results: One sample t tests and mixed linear modeling were used. On average, parents of children with CL +/- P and of children with IH showed significantly lower parenting stress compared to normative data. Anxiety was significantly lower in parents of children with CL +/- P than that in the norm group. Visibility of the condition was not related to distress or parenting stress. Child behavioral problems were positively related to parenting stress, depression, and hostility. Conclusions: Parents of children with CL +/- P and IH report less distress and parenting stress compared to the norm. On average, these parents seem well adjusted. A practical implication is to monitor parents of children with behavioral problems.Stress and Psychopatholog

Ocular and adnexal anomalies in craniofacial microsomia: a systematic review

Ocular anomalies may occur in craniofacial microsomia (CFM). The aim of this systematic review was to review the literature on ocular anomalies and their incidence, in order to estimate the need for ophthalmological screening in CFM patients. Online databases were searched, and data on the number of patients, type and incidence of ocular anomalies, and visual acuity were extracted. Four subgroups of ocular and adnexal anomalies were identified, to provide an overview of the different anomalies. Twenty-five papers analysing 1419 patients in total were included. Ocular anomalies were documented in 6.7–100% of patients. The most reported type I ocular anomalies were eyelid coloboma, lipodermoids, and orbital dystopia. The most reported type II ocular anomalies were epibulbar dermoid, microphthalmia, and anophthalmia. Ptosis

Management and outcomes of obstructive sleep apnea in children with Robin sequence, a cross-sectional study

Objective: The objective of this cross-sectional study is to assess the prevalence, course, and management of obstructive sleep apnea (OSA) in children with Robin sequence (RS) aged 1–18 years. Materials and methods: A cross-sectional study was conducted in 63 children aged 1 to18 years with RS. Patient data were collected on baseline characteristics and management. OSA was evaluated by polysomnography. Results: Sixty-three children with RS were included (median age 8.0 years) and divided into two groups based on the initial treatment: prone positioning or respiratory support. Respiratory support was more often indicated in children with a non-isolated RS (p < 0.05). At cross section, in the prone positioning group (n = 32), one child was diagnosed with OSA. In the respiratory support group (n = 31), 13 children (42 %) had respiratory problems of whom 10 needed respiratory support. Conclusions: Between the age of 1 and 18 years, almost one out of four children with RS still has respiratory problems. Children with RS, who can be treated with prone positioning only as an infant, are not likely to develop obstructive airway problems at a later age. In contrast, children who need respiratory support early after birth are at risk of continuing or re-developing OSA after the age of 1 year. Clinical relevance: This study shows that those who need respiratory support at an early age need careful monitoring until adulthood
