OBJECTIVES Our aim was to present laryngovideostroboscopic findings in unilateral superior laryngeal nerve paresis and paralysis. STUDY DESIGN AND SETTING Retrospective case review, academic voice clinic. METHODS Blinded retrospective review of videostroboscopic recordings from cases confirmed by laryngeal electromyography. RESULTS Three cases of unilateral superior laryngeal nerve paresi...

BACKGROUND Perioperative examination ofthe vocal folds with flexible fiberoptic laryngoscopy is not always feasible. Prior studies suggest vocal fold ultrasound may provide a useful screening tool, however, correlation to laryngoscopic findings is necessary. The purpose of the case series was to validate vocal fold ultrasound in the adult population and to correlate the ultrasound findings to t...

Traditional speech processing methods for laryngeal pathology assessment assume linear speech production, with measures derived from an estimated glottal ow waveform. They normally require the speaker to achieve complete glottal closure, which for many vocal fold pathologies cannot be accomplished. To address this, a nonlinear signal processing approach is proposed which employs a di erential T...

Objectives: Diplophonia is a common and often misinterpreted symptom of disordered voice and needs objectification. It was hypothesized that diplophonia is produced by two distinct oscillators, which yields a profound physiological interpretation. Based on that hypothesis, an audio signal processing algorithm for the detection of diplophonia is proposed, tested and validated. Its performance is...

Descriptions of vocal fold lesions related to autoimmune diseases are rare in the literature, and focus mainly on rheumatoid nodules. This is the first report in which autoimmune diseases were promptly suspected by the observation of a unique white transverse submucosal lesion in the vocal fold during clinical examination. This lesion, reported only in autoimmune disease, has been called the ba...

BACKGROUND Vocal cord leukoplakia comprises a variety of lesions. The purpose of this study was to stratify vocal leukoplakias before surgery. METHODS Patients with an initial diagnosis of vocal leukoplakia who underwent surgical excision at a tertiary referral center in Taiwan were recruited for this study. Their clinical records, including age, sex, preoperative laryngoscopic images in the ...
