Pediatric Voice Disorders

Objective: The vibratory source for voicing in children with dysphonia is classified into three categories including a glottal vibratory source (GVS) observed in those with vocal lesions or hyperfunction; supraglottal vibratory sources (SGV

Pediatric dysphonia can be categorized by the vibratory source used for voicing: the glottal vibratory source (GVS) and supraglottal vibratory source (SGVS). While voice quality assessment is integral to clinical voice care, there is limite

Objective: As with adult voices, the reliability of Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) appears to vary widely for pediatric voices, especially for supraglottal voice sources (SGVS). The current study compared the rel

Objective: The role of pitch perception in the assessment of pediatric dysphonia remains underexplored. Aperiodicity associated with severe dysphonia poses a vexing problem for conventional measurement methods that rely on signal periodicit

Purpose: Severe dysphonia in children often poses a challenge for conventional acoustic measurement methods due to the high degree of aperiodicity, which can result in invalid or unreliable measures. Signal typing can support the validity o

Voice disorders are best assessed by examining vocal fold dynamics in connected speech. This can be achieved using flexible laryngeal high-speed videoendoscopy (HSV), which enables us to study vocal fold mechanics with high temporal details

Objective: To provide data on the measurable vocal fold vibratory differences in children with and without vocal fold lesions using high-speed videoendoscopy. Design: Prospective study, 24 participants (8 healthy; 16 with lesions) between t

Objective: This study proposes a new computational framework for automated spatial segmentation of the vocal fold edges in high-speed videoendoscopy (HSV) data during connected speech. This spatio-temporal analytic representation of the voc

Investigating the phonatory processes in connected speech from high-speed videoendoscopy (HSV) demands the accurate detection of the vocal fold edges during vibration. The present paper proposes a new spatio-temporal technique to automatica

The design specifications and experimental characteristics of a newly developed laser-projection transnasal flexible endoscope coupled with a high-speed videoendoscopy system are provided. The hardware and software design of the proposed sy

Objectives: To assess correlations between age group and functional, physical, emotional, and talkativeness domains of the pediatric Voice Handicap Index (pVHI) in pediatric cohorts with and without benign bilateral vocal fold lesions (BVFL

We performed a retrospective review to compare a subjective parental proxy-derived voice handicap survey to an observer-derived method of measuring voice perturbation in children who have undergone airway reconstruction. The main outcome me

Objectives: Post airway reconstruction dysphonia (PARD) is common and has a significant effect on the quality of life of patients. Vocal fold injection augmentation (VFIA) is one treatment that can be used to improve glottic insufficiency i

Introduction: Dynamic voice computerized tomography (DVCT) is a novel technique that provides additional information to characterize laryngeal function for patients with complex airway history that may alter surgical decisions. The goal of

Objectives To compare the ability of the dynamic voice computed tomography (CT) scan to characterize laryngeal function in airway reconstruction patients vs bedside endoscopic nasopharyngolaryngoscopy and videolaryngostroboscopy. Study Desi

Voice quality has emerged as an additional long-term outcome measure for patients with a history of airway surgery. The goal of this study was to evaluate the impact of preoperative voice assessment on the surgical management of patients wh

Objectives/Hypothesis: The male singing voice through puberty undergoes many changes that present challenges for the singer and choral director. The purpose of this study was to discuss the endoscopic findings seen in prepubescent choir sin

Background/Objectives: Vocal changes in the male singing voice associated with puberty are variable and often unpredictable resulting in challenges for the singer and the choral director. Limited knowledge regarding the physiologic changes
