Objectives: Cepstral measures have mainly been evaluated by studies conducted on dysphonic and healthy adults, and many of these studies have reported the advantages of using cepstral measures for the evaluation of dysphonia however there is a paucity regarding to the cepstral analyses' results in dysphonic children. In this present study, it is hypothesized that cepstral peak prominence (CPP) and some other parameters of cepstral analysis would differ in children with vocal nodules when compared with the same parameters of cepstral analysis of healthy children.

The design of cell-based therapies for vocal fold tissue engineering requires an understanding of how cells adapt to the dynamic mechanical forces found in the larynx. Our objective was to compare mechanotransductive processes in therapeutic cell candidates (mesenchymal stromal cells from adipose tissue and bone marrow, AT-MSC and BM-MSC) to native cells (vocal fold fibroblasts-VFF) in the context of vibratory strain. A bioreactor was used to expose VFF, AT-MSC, and BM-MSC to axial tensile strain and vibration at human physiological levels. Read More

Alternative mathematical models predict differences in how animals adjust the timing of their calls. Differences can be measured as the effect of the timing of a conspecific call on the rate and period of calling of a focal animal, and the lag between the two. Here, I test these alternative hypotheses by tapping into harbor seals' (Phoca vitulina) mechanisms for spontaneous timing. Read More

Objectives/hypothesis: The aim of this study was to analyze the phoniatric and respiratory outcomes of a subset of bilateral vocal cord paralysis (BVCP) patients who were all treated with unilateral endoscopic arytenoid abduction lateropexy (EAAL). EAAL is a nondestructive, minimally invasive glottis widening operation, which does not damage either the surgically treated or the contralateral vocal cord. Therefore, it does not impair the regeneration potential of the recurrent laryngeal nerve. Read More

Objective: The transcricothyroid (CT) membrane approach is a good option for office-based vocal fold injection (VFI). However, because the needle tip is invisible during injection using the CT approach, precise localization requires a high level of experience, and mastering this approach involves a steep learning curve. To overcome current limitations, we conceptualized a novel technique: real-time light-guided VFI (RL-VFI), which enables simultaneous VFI under direct visualization of the lighted needle tip.

Additionally, spontaneous reinnervation of the larynx after recurrent laryngeal nerve (RLN) injury is often disorganized, resulting in subpar function. This study investigates use of tissue-engineered cartilage and motor endplate-expressing (MEE) tissue-engineered skeletal muscle implants for laryngeal reconstruction and the promotion of organized reinnervation after RLN injury.

Listeners remember vocal melodies better than instrumental melodies, but the origins of the effect are unclear. One explanation for the 'voice advantage' is that general perceptual mechanisms enhance processing of conspecific signals. An alternative possibility is that the voice, by virtue of its expressiveness in pitch, simply provides more musical information to the listener. Read More

Clinical tests of cochlear implant (CI) outcomes in sentence recognition cannot fully reflect CI users' self-reported quality of life (QoL). Here, vocal emotion recognition scores, speech reception thresholds (SRTs), and demographic factors were tested as predictors of QoL scores assessed with the Nijmegen Cochlear Implant Questionnaire in postlingually deafened adult CI users. After correction for multiple comparisons, vocal emotion recognition scores were significantly correlated with QoL scores in all subdomains (social interaction, self-esteem, etc. Read More

Procedural skill learning requires iterative comparisons between feedback of self-generated motor output and a goal sensorimotor pattern. In juvenile songbirds, neural representations of both self-generated behaviors (each bird's own immature song) and the goal motor pattern (each bird's adult tutor song) are essential for vocal learning, yet little is known about how these behaviorally relevant stimuli are encoded. We made extracellular recordings during song playback in anesthetized juvenile and adult zebra finches ( Taeniopygia guttata) in adjacent cortical regions RA (robust nucleus of the arcopallium), AId (dorsal intermediate arcopallium), and RA-cup, each of which is well-situated to integrate auditory-vocal information: RA is a motor cortical region that drives vocal output, AId is an adjoining cortical region whose projections converge with basal ganglia loops for song learning in the dorsal thalamus, and RA-cup surrounds RA and receives inputs from primary and secondary auditory cortex.

Near total laryngectomy (NTL) is a safe alternative to total laryngectomy in salvaging lateralized radiation failures.

Background: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures.
Methods: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL.
Results: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage.
