Obstructive respiratory stress and feeding difficulties in infants with Robin sequence (RS) may result in poor weight gain or loss. Following failure of conservative treatment, surgical options include mandibular distraction osteogenesis (MDO) and tongue-lip adhesion (TLA). Whilst both techniques have demonstrated to improve airway patency and feeding behavior, an advantage of either in restoring weight growth remains unknown.

Objective: Heterogeneity in both nomenclature and diagnostic criteria has hindered the interpretation of research into the congenital condition most widely known as (Pierre) Robin syndrome or sequence. In 2009, the discussion regarding its diagnosis and nosology was reopened to converge on a uniform eponym and standard set of diagnostic criteria. The objective of this study was to assess the impact of this debate.

Background: Traditional open corrective surgery for isolated sagittal synostosis entails significant blood loss, transfusion rates, morbidity, and a lengthy hospitalization. Minimally invasive strip craniectomy (MISC) was introduced to avoid the disadvantages of open techniques.

Objectives: The aim of the study was, first, to compare the anesthesia practice in MISC and open extended strip craniectomy (OESC), and, second, to evaluate the incidence of perioperative complications in both surgical procedures.

Objectives: Partial tooth agenesis is frequently observed in Robin sequence. Tooth anomalies are increasingly considered as an extended phenotype of the cleft palate population. The study objective was to compare the prevalence and patterns of tooth agenesis in a group of patients with non-syndromic Robin sequence (ns-RS) and a group with non-syndromic cleft palate (ns-CP).

Robin sequence (RS) can be defined as the combination of micrognathia and upper airway obstruction/glossoptosis causing neonatal respiratory problems, with or without a cleft palate and either isolated or non-isolated. Pathogenesis varies widely. We hypothesize that optimal treatment depends on pathogenesis and therefore patients should be stratified according to diagnosis.

The birth prevalence of Robin sequence (RS) is frequently cited to be 1 in 8,500 to 14,000 live births (range: 7,1-11,8 per 100.000), which is based on just a few epidemiological studies. The objective of this study is to contribute to the limited knowledge of the epidemiology of RS by determining the frequency of RS in a cleft palate (CP) population and the estimated birth prevalence in live births in the Netherlands, using distinct diagnostic criteria.

Objectives: Initial approaches to and treatments of infants with Robin sequence (RS) is diverse and inconsistent. The care of these sometimes critically ill infants involves many different medical specialties, which can make the decision process complex and difficult. To optimize the care of infants with RS, we present our institution's approach and a review of the current literature.

Article Synopsis
  • The study aimed to determine the infant mortality rate (IMR) for Dutch patients with isolated oral clefts and those with clefts associated with other malformations, analyzing specific cleft types and causes of death.
  • A review of patient charts from 1997 to 2011 revealed an overall IMR of 2.09% for oral clefts, significantly higher than the general Dutch IMR of 0.45%.
  • The high IMR was mainly attributed to associated congenital malformations, highlighting the need for thorough medical assessments and consultations upon diagnosis of oral clefts.

Background: In Europe there have been few detailed reports on the clinical characteristics of microtia patient populations. The objective of the present study is to contribute to our insight of microtia in Europe by examining the Dutch microtia population treated in the University Medical Center Utrecht (UMCU) with regards to its clinical features and associated anomalies. In addition, an overview of the literature is provided for thorough comparison.
