Method A crossover, double-blinded study was conducted for 12 weeks. Twelve adult participants were randomly assigned to two groups. During the first 6-week test interval, one group continued to use their everyday FSP strategy, whereas the other group was upgraded to the FS4 strategy. In the second 6-week interval, the two groups switched coding strategies. Speech perception was measured at the end of each test interval with the Oldenburg Sentence Test and the Göttingen Sentence Test. Participants completed the Speech, Spatial and Qualities of Hearing Scale at the end of each test interval and a simple preference test at the end of the study. Results There was no significant difference in speech perception test results obtained wit...

Doch kann man mit einem CI auch Tauchen und Fliegen? Halten das operierte Ohr sowie das Implantat selbst den ausgeprägten Druckveränderungen stand? Bisher gibt es keine klaren Empfehlungen und sehr wenig Literatur über die Risiken des Gerätetauchens sowie des Fliegens mit CI. Material und Methoden In einer hypo-/hyperbaren Druckkammer wurden Menschen mit einem CI einem Druckprofil mit Phasen des Druckanstiegs sowie Phasen des Druckabfalls ausgesetzt, sodass zunächst ein Flug und dann ein Tauchgang simuliert wurden. Sowohl vor als auch nach der Druckkammermessung erfolgten eine Ohrmikroskopie sowie eine Messung der Impedanzen des Cochlea-Implantats. Zusätzlich füllte jeder Patient einen symptombezogenen Fragebogen vor sowie nach der Druckkammermessung aus. Ergebnisse In der Druck...

This has important consequences for speech recognition when several talkers speak simultaneously. This examination considered the comparison of clear speech and noise-vocoded sentences as maskers. For the speech maskers it could be shown that good CI performers are able to benefit from F0 differences between target and masker. This was due to the fact that a F0 difference of 80 Hz significantly reduced target-masker confusions, an effect that was slightly more pronounced in bimodal than in bilateral users.

The genetic forms are subdivided into syndromic and non-syndromic types, and show different inheritance patterns with a strong preponderance of autosomal-recessive forms. To date, only a single locus for non-syndromic autosomal-dominant AS/AN (AUNA1) has been reported in a single family, in which a non-coding DIAPH3 mutation was subsequently described as causative. Materials and Methods: Here, we report detailed clinical data on a large German AS/AN family with slowly progressive postlingual hearing loss. Affected family members developed their first symptoms in their second decade. Moderate hearing loss in the fourth decade then progressed to profound hearing impairment in older family members. Comprehensive audiological and neurological tests were performed in the affected family members. Genetic tes...

Over the last 20 years, several CCDDs have been identified as neurodevelopmental disorders that are caused by mutations of genes involved in brain and cranial nerve development, e.g. KIF21A and TUBB3 that each plays a pivotal role for microtubule function. In a five-generation pedigree, we identified a heterozygous mutation of TUBB6, a gene encoding a class V tubulin which has not been linked to a human hereditary disease so far. The missense mutation (p.Phe394Ser) affects an amino acid residue highly conserved in evolution, and co-segregates with a phenotype characterized by congenital non-progressive bilateral facial palsy and congenital velopharyngeal dysfunction presenting with varying degrees of hypomimia, rhinophonia, impaired gag reflex and bilateral ptosis. Expression of the mutated protein in yeast led to an impaired viability compared to wildtype cells when exposed to the microtubule-poison benomyl. Our findings enlarge the spectrum of tubulinopathies and emphasize that mutations of TUBB6 should be considered in patients with congenital non-progressive facial palsy. Further studies are needed to verify whether this phenotype is indeed part of the CCDD spectrum.

Method Single words and sentences were manipulated using isolated or combined F0 and VTL cues. Using an 11-point rating scale, CI recipients and listeners with normal hearing rated the maleness/femaleness of the corresponding voice. Results Speaker gender ratings for combined F0 and VTL modifications were similar across all stimulus types in both CI recipients and listeners with normal hearing, although the CI recipients showed a somewhat larger ambiguity. In contrast to listeners with normal hearing, F0-VTL and F0-only modifications revealed similar ratings in the CI recipients when using words as stimuli. However, when sentences were used, a difference was found between F0-VTL–based and F0-based ratings. Modifying VTL cues alone did not affect ratings in ...

A tool for preoperative assessment would be helpful for counseling parents. This study evaluates the outcome after CI in children with AS/AN and with sensorineural hearing loss (SNHL), and correlates it with the preoperative ECochG results in order to find specific parameters of prognostic value. The improvement of auditory behavior after CI was retrospectively assessed using the LittlEARS questionnaire and quantified in a score (LS). This score was correlated with the CAP/SP ratio in the preoperative ECochG. The score was further correlated with the patient's age six months following CI. Nine children with AS/AN were compared to nine children with SNHL. Both groups showed a significant improvement in LS following CI. There was a significant positive correlation between the CAP/SP ratio and the improvement in LS in all children. The correlation between age and LS was significantly negative in the SNHL group and positive in the AS/AN group. All children with AS/AN and SNHL benefit to a similar extent from CI. The preoperatively assessed CAP/SP ratio has a prognostic value for the development of auditory behavior following CI.

They can occur at any point along the migratory path of the thyroid gland anlage until the 2nd or 3rd decade of life. The usual symptoms leading to the diagnosis are painless midline neck masses orfistulas. Despite their close proximity, the cysts normally do not affect the larynx. We report on the eighth case mentioned in the world literature of a thyroglossal duct cyst invading the larynx in a 62-year-old patient. Preoperatively, the voice of the patient sounded metallic, and the frequency of the voice field was reduced. Postoperatively, the voice onset was physiological, and the voice increased by an octave in the higher frequencies. The intonation of the voice was steady. The analysis of formants of the vowels "a" and "i" showed that the fourth formant of the vowel "i" was lower in frequency postoperatively.

Die Routineuntersuchung ist völlig unauffällig, der Versuch den Knaben altersentsprechende Worte mit „K“ nachsprechen zu lassen, schlägt fehl. Aus der Tasche der Mutter ragt eine Cola-Flasche hervor. Möglicherweise mag das Kind Coca Cola? Also lautet die nächste Frage: „Sag bitte einmal Cola“. Der Junge, zuvor in Abwehrhaltung mit Stirnfalte, geballten Fäusten, leicht gesenktem Kopf, verändert seine Physiognomie innerhalb von Sekunden: er blickt auf und sagt kurz und knapp: „Light“.

Cross-sectional study in university tertiary referral centers and at hearing aid dispensers. Verbal communication performance was assessed by the Functioning after Pediatric Cochlear Implantation (FAPCI) instrument. The FAPCI was administered to 38 parents of children using CIs and 62 parents of children with HAs. According to the WHO classification, children with HAs were categorized into three groups (mild-moderate-severe hearing loss). Analysis of variance (ANOVA) was performed on the FAPCI scores, with study group, hearing age (i.e., device experience), and age at hearing intervention as sources of variation. ANOVA showed that hearing age and study group significantly contribute to the FAPCI outcome. In all study groups except the children with mild hearing loss, FAPCI scores increased alongside growing experience with the devices. Children with mild hearing loss using HAs showed higher scores than those with severe hearing loss or implanted children. There were no significant differences between the children with CIs and the children with moderate or severe hearing loss using HAs. Real-world verbal communication abilities of children with CIs are similar to those of children with moderate-to-severe hearing loss using amplification. Because hearing age significantly influences performance, children with moderate-to-severe hearing loss using HAs and implanted children catch up with children with mild hearing loss at a hearing age of approximately 3 years.

The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant...

However, it can still complicate trauma to the respiratory and digestive tracts, including operative procedures. A patient with cervicofacial actinomycosis commonly gives a history of recent dental manipulation which usually, involves extraction of a mandibular molar. The common initial symptoms of infection--such as, sudden onset of cervicofacial pain, swelling, erythema, edema and suppuration--can be absent. Infection due to actinomyces is a well-known mimic of malignancy is clinical, radiological and pathological findings. In the case described a 65-year-old man had a mass in his right parotid area. Because of its painless rapid growth with infiltration of the mandible as demonstrated by clinical findings and CT and MRI scans, we established an initial diagnosis of salivary gland malignancy. Salivary gland biopsy then revealed a histological picture of infection due to actinomyces. Therapy was initiated with intrav...

Prospective observational multicenter study. Thirty-six patients with BVFP underwent transoral surgery using standard surgical procedures to unilaterally widen the glottic area. Postoperative adverse events (AEs) including severe adverse events (SAEs) were registered continuously. Pre- and 6-month postoperative evaluations included the 6-Minute Walk Test, the 36-Item Short Form Health Survey (SF-36), the Glasgow Benefit Inventory, the 12-Item Voice Handicap Index (VHI-12), and a Fiberoptic Endoscopic Evaluation of Swallowing graded according to the Penetration-Aspiration-Scale. The patients underwent posterior cordotomy, partial arytenoidectomy, or permanent laterofixation as single procedures or in combination. Forty-seven percent of the patients had postoperative AEs. Dyspnea was the most frequent AE (45%). In 40% of AEs, the events were severe (SAEs), and 72.5% were related to the study intervention. Revision surgery leading to prolonged hospitalization or rehospitalization was necessary in nine cases (25%). Laterofixation was correlated to a decreased risk of AEs (P = 0.042). Six months after surgery, a significant improvement was seen in the SF-domains: Physical component score (P = 0.008), physical functioning (P = 0.001), physical role (P = 0.031), and vitality (P = 0.032). Concerning the voice handicap, only the VHI-12 physical subscore showed a decrease (P = 0.005). The total score and other VHI-12 subscores did not change significantly (all P > 0.05). BCVP patients profit from modern transoral surgery for unilateral glottic widening; quality of life is improved; and the voice is preserved. Nevertheless, postoperative complications are frequent. 2b. Laryngoscope, 2015.
