Vibratory source, vocal quality and fundamental frequency following pediatric laryngotracheal reconstruction

Perceptual Evaluation of Severe Pediatric Voice Disorders: Rater Reliability Using the Consensus Auditory Perceptual Evaluation of Voice

“…These estimates are all considered moderate to strong, but these findings depart from the authors' previous work and others reported in the literature. 19,22 An inverse relationship between roughness and breathiness has been documented, 10 and is attributed to presumed physiological correlates (breathinessglottal insufficiency; roughness-laryngeal hyperfunction or tissue change) that tend not to coexist. Likewise, the anatomic changes associated with this population yield voice qualities that can be extremely breathy with little to no vibratory sound source or extremely rough as in ventricular phonation.…”

“…Anatomic alterations can include scarred and off-level vocal folds, anterior commissure blunting, prolapsed arytenoids, restricted or fixed cricoarytenoid joint mobility or paralyzed vocal folds, and altered supraglottic structures. 22,[24][25][26][27] Figure 3 depicts laryngeal changes commonly observed in this population. To date, the relationship between specific number and type of surgeries and resulting voice outcomes remain unclear, but is the central focus of our ongoing research.…”

“…[20][21][22] To date, only one study systematically examined the reliability of expert perceptual ratings of voice in children using the CAPE-V. Krival et al 22 examined the relationship of vibratory source, vocal quality, and fundamental frequency (F 0 ) in a small cohort of children post-laryngotracheal reconstruction (LTR). Perceptual ratings provided by three experienced raters were collected for 16 participants with variable laryngeal vibratory sources (eg, glottic, supraglottic, mixed).…”

Management of oral feeding in children undergoing airway reconstruction

“…[2][3][4][5] Recently, several studies have begun to characterize voice outcome following laryngotracheal reconstruction (LTR). [6][7][8][9] Many children who undergo LTR present with dysphagia preoperatively and some may develop it postoperatively. 10 We routinely screen our patients for swallowing difficulties before performing LTR.…”

Voice Abnormalities at School Age in Children Born Extremely Preterm

“…Voice outcomes in studies of children intubated in the neonatal period have so far been limited to those undergoing laryngeal reconstruction for recognized airway complications [20][21][22] or after surgical ligation of the PDA, 23 and to extremely low birth weight (ELBW) infants at 12 months of corrected age. 19 Mild voice abnormalities, such as breathiness and roughness, are common inyoungchildrenbecause ofvocaloveruse in childhood.…”
