Benign laryngeal disorders result in dysphonia because of effects on glottic closure and the vibratory characteristics of the true vocal fold. Treatment is initially directed at reversing medical conditions and patterns of abuse with surgery reserved for unresolving lesions resulting in troublesome dysphonia. Benign lesions that require surgery are excised as precisely as possible sparing overl...

Fifty-one patients with established pulmonary tuberculosis underwent clinical evaluation and endoscopic examination of the larynx to determine the manifestations of laryngeal involvement. There were 46 males and 5 females (mean age 38 years). Fever, cough and haemoptysis were the prime pulmonary complaints while hoarseness, weak voice and episodic dyspnoea were the main laryngeal symptoms. Site...

OBJECTIVES/HYPOTHESIS This study assessed the long-term efficacy and recurrence rates of percutaneous steroid injections (PSIs) for benign vocal fold lesions. STUDY DESIGN Prospective clinical study. METHODS A prospective human clinical trial was performed from October 2008 to September 2014 at Soonchunhyang University Hospital, Bucheon, Korea. Percutaneous steroid injection was performed i...

INTRODUCTION Hyperkinetic (hyperfunctional) dysphonia is a common pathology. The disorder is often found in vocal professionals faced with high vocal requirements. OBJECTIVE The objective of this study was to evaluate the effects of vocal therapy on voice condition characterized by hyperkinetic dysphonia with prenodular lesions and soft nodules. METHODS The study included 100 adult patients...

Introduction:Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structure...

Over the 8-year period 1971--1978, 743 benign lesions of the larynx, of which 551 were pseudotumors and 192 were benign neoplasms, were surgically treated at Groote Schuur Hospital. In comparison, during the same period 402 malignant tumours of the larynx were also seen. The commonest benign lesions were vocal cord nodules, almost exclusively found in women, and the vocal cord polyp, predominan...

Young songbirds produce vocal "babbling," and the variability of their songs is thought to underlie a process of trial-and-error vocal learning. It is known that this exploratory variability requires the "cortical" component of a basal ganglia (BG) thalamocortical loop, but less understood is the role of the BG and thalamic components in this behavior. We found that large bilateral lesions to t...
