PURPOSE To study the safety of prophylactic level VII nodal dissection regarding hypoparathyroidism (temporary and permanent) and vocal cord dysfunction (temporary and permanent) and its impact on disease free survival. MATERIALS AND METHODS This prospective study concerned 63 patients with papillary thyroid carcinoma with N0 neck node involvement (clinically and radiologically) in the period...

OBJECTIVES The aim of this study was to design a clinical vocal loading task (VLT) and to track vocal loading and recovery in voice-healthy subjects. STUDY DESIGN Pilot study. METHODS Voice-healthy subjects (six female, five male) took part in a controlled VLT in the voice clinic. The VLT was designed to induce vocal fatigue. The subjects read aloud while making themselves heard through amb...

OBJECTIVES/HYPOTHESIS Besides the classical sexual receptors, the expression of a recently clarified transmembrane G protein-coupled receptor (GPR30) has not been reported in the vocal fold so far. We aimed to study whether GPR30 is expressed in the human vocal fold. STUDY DESIGN Experimental study using pathologic human vocal fold tissues. METHODS Reverse-transcription polymerase chain rea...

acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

OBJECTIVES This study assessed the regenerative efficacy of basic fibroblast growth factor (FGF) in a rabbit model of chronic vocal fold scarring and then confirmed its utility and safety in a prospective trial of patients with this condition. METHODS FGF was injected three times, at 1-week intervals, into a chronic vocal fold scar created in a rabbit model. After 1 month, mRNA level of proco...

OBJECTIVES/HYPOTHESIS The relationship between patient-reported vocal handicap and clinician-rated measures of vocal dysfunction is not understood. This study aimed to determine if a correlation exists between the Voice Handicap Index-10 (VHI-10) and the Voice Functional Communication Measure rating in the National Outcomes Measurement System (NOMS). STUDY DESIGN Retrospective case series. ...

OBJECTIVES/HYPOTHESIS As laryngeal electromyography (LEMG) becomes more refined, accurate predictions of vocal fold motion recovery are possible. Focus has been on outcomes for patients with poor prognosis for vocal fold motion recovery. Limited information is available regarding the expected rate of purposeful vocal fold motion recovery when there is good to normal motor recruitment, no signs ...

BACKGROUND The Type I Posterior Glottic Stenosis (PGS-I) is a well-described but uncommon clinical entity. Despite this, there is little known about the outcome of surgical treatment. METHODS Retrospective case series. RESULTS Thirteen cases met inclusion criteria. All but one patient had a tracheostomy at the time of initial evaluation. At the postoperative visit, seven patients (54%) had ...
