[Subjective and objective hearing test results for children with orofacial clefts]. / Audiometrische Daten subjektiver und objektiver Hörprüfungen bei Kindern mit orofazialen Spaltbildungen--eine prospektive Längsschnittuntersuchung.

OBJECTIVE: The hearing status of children with orofacial clefts was analysed using objective hearing tests over an average of 38.7 months following soft palate closure. We investigated the influence of: timing of closure, type of cleft, importance of grommets insertion and concomitant craniofacial syndromes such as Pierre Robin (PRS). MATERIAL AND METHODS: 70 children were selected for prospective audiometric testing twice yearly. RESULTS: The average age at surgical closure was 8.3 months. More than half had PRS, but their hearing levels were not significantly different from those who did not. Neither did cleft type or timing of closure seem to have any influence. The portion of children with a hearing level better than 30 dB increased after repair from 38.6% to 81.4%--significant at 0.001 and remained stable more than 24 months later. In the group of children with concomitant grommets insertion, it was also found that also more than 80% achieved longstanding normal hearing. CONCLUSIONS: There is no long lasting hearing loss which has any relevance to speech. The only intervention of any consequence is insertion of pressure equalising/tympanostomy tubes (grommets) in cases of primary palatal clefts when hearing is substantially impaired at the time of soft palate closure.

Auditory cortex activation is modulated by emotion: a functional near-infrared spectroscopy (fNIRS) study.

Visual emotional stimuli evoke enhanced activation in early visual cortex areas which may help organisms to quickly detect biologically salient cues and initiate appropriate approach or avoidance behavior. Functional neuroimaging evidence for the modulation of other sensory modalities by emotion is scarce. Therefore, the aim of the present study was to test whether sensory facilitation by emotional cues can also be found in the auditory domain. We recorded auditory brain activation with functional near-infrared-spectroscopy (fNIRS), a non-invasive and silent neuroimaging technique, while participants were listening to standardized pleasant, unpleasant, and neutral sounds selected from the International Affective Digitized Sound System (IADS). Pleasant and unpleasant sounds led to increased auditory cortex activation as compared to neutral sounds. This is the first study to suggest that the enhanced activation of sensory areas in response to complex emotional stimuli is apparently not restricted to the visual domain but is also evident in the auditory domain.
