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)
To study the occurrence and type of misarticulations in dental consonants /r/, /s/ and /l/ 280 (115 girls, 165 boys) 6-year-old cleft children were examined by 1 of the 2 experienced speech pathologists of the cleft team. The patients included 82 children with isolated cleft palate (CP), 82 with cleft lip with (34) or without (48) cleft alveolus [CL(A)], 85(More)
The present study deals with various factors affecting speech, particularly its resonance, in patients with isolated cleft palate. For that purpose a method to evaluate hypernasality was developed. The degree of hypernasality was assessed in terms of hypernasality indexes by means of a modified cul-de-sac hypernasality test. The phonetic content of the test(More)
The aim of this study was to examine whether maxillary and mandibular dental arch width, length, and palatal height dimensions are associated with the occurrence of misarticulations (phonetic or phonologic errors) in the dental consonants /r/, /s/, and /1/ in different cleft types and sexes. The subjects were 263 (109 girls, 154 boys) 6-year-old(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)

This study compares 30 cleft lip and palate (CLP), 55 cleft palate (CP) and 28 cleft lip (CL) children in terms of descriptive speech data, nasalance data and the frequency of secondary surgery performed on patients. The CLP children had less hypernasality and audible nasal air emissions than CP children. The groups were equal with respect to articulation(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)
OBJECTIVE To characterise the activation of the contra- and ipsilateral primary somatosensory cortex (SI) after tactile stimulation of the face. METHODS Trigeminal somatosensory evoked magnetic fields (TSEFs) were recorded after tactile stimulation of the lower lip, cheek, chin and forehead in 11 healthy subjects. The responses were determined visually(More)
