BACKGROUND TWINKLE (c10orf2) gene is responsible for autosomal dominant progressive external ophthalmoplegia (PEO). In rare cases, additional features such as muscle weakness, peripheral neuropathy, ataxia, cardiomyopathy, dysphagia, dysphonia, cataracts, depression, dementia, parkinsonism, and hearing loss have been reported in association with heterozygous mutations of the TWINKLE gene. MET...

Anterior cervical osteophytes are common and usually asymptomatic in elderly people. Due to mechanical compressions, inflammations, and tissues swelling of osteophytes, patients may be presented with multiple complications, such as dysphagia, dysphonia, dyspnea, and pulmonary aspiration. Paradoxical vocal cord motion is an uncommon disease characterized by vocal cord adductions during inspirati...

Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy fou...

Spasmodic dysphonia is a disabling voice condition caused by a chronic neurological disorder of central motor processing. Present therapy is directed at relief of symptoms rather than cure. Botulinum toxin type A injection into the thyroarytenoid muscle has become the pre-eminent approach for treatment of adductor spasmodic dysphonia. Botulinum toxin A injections can be performed in an out-pati...

This study sought to use videostrobolaryngoscopy to clarify possible biomechanical causes of dysphonia in patients with laryngeal tension-fatigue syndrome, a chronic functional dysphonia due to vocal abuse and misuse. The videostrobolaryngoscopic records of 301 laryngeal tension-fatigue syndrome patients were reviewed. The focus of observation was the visual characteristics of the mucus layer, ...

Muscle tension dysphonia (MTD) is a voice disorder that occurs as a result of misuse or abuse of the voice [1]. While there is no neurological damage to the larynx nor any structural abnormality present, patients with MTD have limitations in vocal vibrations due to laryngeal muscle tension. Consequently, such patients demonstrate pathological voice problems, such as hoarseness, strained and str...
