CATCH syndrome, caused by a microdelection in chromosome 22, is characterized by cleft palate and cardiac anomalies. The majority of these children also have learning difficulties or speech and language deficits. These problems are often due to the dysmorphology of the articulatory system. In the present study, the duration of auditory sensory memory, which(More)
OBJECTIVE Up to 46% of individuals with oral clefts suffer from language-learning disabilities. The degree of these disabilities varies according to cleft type. The pathogenesis of cognitive malfunctioning or its relationship with cleft type is not known. We investigated persistence of auditory short-term memory (STM) that is implicitly involved in(More)
Our recent study demonstrated with the brain's automatic change-detection response, the mismatch negativity (MMN) of the event-related potentials (ERPs), that the duration of auditory sensory memory is significantly shorter in school-age children with CATCH syndrome than in healthy age-matched controls. One of the characteristic symptoms of this syndrome,(More)
INTRODUCTION This study was designed to determine the incidence of Chiari malformation (CM) in nonsyndromic single suture craniosynostosis (N-SSSC). MATERIALS AND METHODS A retrospective analysis of brain magnetic resonance imaging (MRI) studies of children undergoing craniofacial surgery during 1 January, 2004-31 March, 2009 in Cleft Palate and(More)
OBJECTIVES Our recent studies have demonstrated that the brain's automatic change-detection response, the mismatch negativity (MMN) of the event-related brain potential (ERP), is significantly attenuated in school-age children with CATCH syndrome and in children of the same age with cleft palate but without the CATCH syndrome. Among other problems, various(More)
It is suspected that the developmental delay in school-aged children diagnosed as infants suffering from plagiocephaly is caused by the modification of the skull form. To detect possible cognitive impairment in these children, we examined auditory ERPs to tones in infant patients. The infants with plagiocephaly exhibited smaller amplitudes of the P150 and(More)
Language and learning disabilities occur in almost half of individuals with oral clefts. The characteristics of these cognitive dysfunctions vary according to the cleft type, and the mechanisms underlying the relation between cleft type, cognitive dysfunction, and cleft-caused middle-ear disease are unknown. This study investigates preattentive auditory(More)
Children with nonsyndromic oral clefts and with the CATCH 22 syndrome (acronym for cardiac defects, abnormal faces, thymus hypoplasia, clefts, and hypocalcemia) display a range of language and learning disabilities, the neurofunctional bases of which are not yet understood. This review summarizes recent event-related brain potential (ERP) studies on central(More)
Maxillary advancement may result in movement of the posterior border of the hard palate with its soft palate attachment, which may cause impairment of velopharyngeal (VP) function. We examined VP function before and after Le Fort I osteotomy in 15 cleft lip and palate patients. The extent of maxillary advancement was measured by means of standard(More)
PURPOSE Craniosynostosis may lead to reduced intracranial volume (ICV) and disturb normal brain growth and development. Thus, ICV is an important parameter with respect to the surgical outcome. Current methods for ICV determination from computed tomography (CT) images have drawbacks. The aim of this study was to investigate the performance of the novel(More)
