OBJECTIVES/HYPOTHESIS: Optical coherence tomography (OCT) is a promising technology to noninvasively assess vocal fold microanatomy. The goal of this study was to develop a methodology using OCT to identify quantifiable markers of vocal fold development. STUDY DESIGN: In vivo study. METHODS: A two-step process was developed to reproducibly image the midmembranous vocal fold edge of 10 patients younger than 2 years and 10 patients between 11 and 16 years of age using OCT...

Objective: 1) Evaluate normal pediatric voice frequency and perturbation measures with Voice Evaluation Suite (VES) and the Multi Dimensional Voice Program (MDVP). 2) Determine consistency of these measures over time. 3) Understand which measures might be most useful for evaluating children with voice disorders. Method: Prospective, longitudinal study of normal voices of 50 children aged 4 to 17 years. Two tests of sustained utterances from each child were evaluated by 2 computerized voice analysis programs for frequency and perturbation...

IMPORTANCE: Paradoxical vocal fold motion (PVFM) affects almost 1 million adolescents in the United States. However, to date, no disease-specific objective measure exists to assess symptom severity and response to treatment in adolescents with exercise-induced PVFM. OBJECTIVES: To validate the Dyspnea Index (DI) quality-of-life instrument (previously validated for adults with breathing disorders) in children aged 12 to 18 years with exercise-induced PVFM and to determine the minimum significant DI change corresponding to patient-reported or caregiver-reported improvement or worsening of symptoms...

IMPORTANCE: Few studies have evaluated the pediatric voice objectively using acoustic measurements. Furthermore, consistency of these measurements across time, particularly for continuous speech, has not been evaluated. OBJECTIVES: (1) To evaluate normal pediatric voice frequency and perturbation using both time-based and frequency-based acoustic measurements, and (2) to determine if continuous speech samples facilitate increased recording stability. DESIGN Prospective, longitudinal study...

PURPOSE OF REVIEW: Historically, information gained from the treatment of unilateral true vocal cord paralysis (UVCP) in adults was the same used to treat children. Today, there is a growing body of literature aimed specifically at the treatment of this condition in children. It is an area of growing interest as UVCP can significantly impact a child's quality of life. RECENT FINDINGS: Children with UVCP may present with stridor, dysphonia, aspiration, feeding difficulties, or a combination of these symptoms...

Pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) has been primarily described in the neurology and psychiatry literature. The symptoms of this syndrome typically are a range of obsessive compulsive disorders and neuromuscular tics. The otolaryngologist occasionally becomes involved with these children when it is deemed that chronic tonsil infections are the source. We report here on a child diagnosed with PANDAS who presented with severe ventricular hyperfunction and adductor spasmodic dysphonia...

OBJECTIVE: To validate the Pediatric Voice-Related Quality-of-Life (PVRQOL) survey, which was designed to assess voice changes over time in the pediatric population. DESIGN: Prospective longitudinal study. SETTING: Outpatient pediatric otolaryngology office practice. PARTICIPANTS: One hundred twenty parents of children aged 2 through 18 years having a variety of otolaryngological diagnoses including disorders that affect the voice...

OBJECTIVE: Laryngo-stroboscopy remains as the clinical gold standard for assessing properties of the glottal phonatory and valvular function. This includes deficits of closure as well as mucosal wave irregularities secondary to abnormal zones of pliability and symmetry. Per-oral stroboscopy has technical limitations in children due to the size of the telescope and issues of patient compliance. However, flexible laryngoscopy is readily performed in newborns and young children. This paper describes the use of a new trans-nasal, digital flexible laryngoscope, which allows for laryngo-stroboscopy in children...

OBJECTIVE: To establish normative values for voice-related quality of life across a broad pediatric otolaryngology population using the Pediatric Voice Outcome Survey (PVOS). DESIGN: Longitudinal study. SETTING: Multiphysician outpatient pediatric otolaryngology practice. METHODS: The PVOS was completed by 385 parents of children and adolescents aged 2 to 18 years. Of the 385 parents, 75 were readministered the instrument 2 weeks after no intervention had been provided...
