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...

INTRODUCTION Congenital laryngeal cysts occur as a result of embryological development anomalies. They are usually situated on the lateral wall of the larynx, in the supraglottic region or on the epiglottis. They are mostly diagnosed in childhood. They are present in 2.4% of population and represent only 7% of all benign laryngeal lesions. Needle aspiration or marsupialization does not give lon...

BACKGROUND Narrow band imaging (NBI) is a new imaging technique for the depiction of tumor-specific neoangiogenesis. The purpose of the present study was to assess the value of NBI in the early diagnosis of laryngeal cancer. METHODS This prospective study includes 205 consecutive patients with a laryngeal lesion scheduled for microlaryngoscopy. NBI was immediately performed after white light ...

High Resolution Laryngeal Ultrasound for diagnosis of vocal cords lesions

Neurophysiological studies of the larynx using laryngeal electroneuromyography (LENMG), which includes electromyography (EMG) and electroneurography (ENG), are essential for assessing neuromuscular function and for differential diagnosis of voice alterations (dysphonia) secondary to specific laryngeal disease or to other more general processes affecting the larynx. Laryngeal disease can be caus...

OBJECTIVE The detailed characteristics and prognosis of nonsurgery-related unilateral vocal fold paralysis (NSUVFP) are currently unclear. This study evaluated the extent of laryngeal nerve lesions and the individual characteristics for patients with NSUVFP. STUDY DESIGN Retrospective, case series. METHODS Patients with unilateral vocal fold paralysis (UVFP) were evaluated using videolaryng...

Experiments were carried out to determine whether there are separate drives from the selected neuronal networks of the brainstem affecting the discharge patterns of laryngeal and respiratory pump muscles during cough. Twenty-four non-decerebrate spontaneously breathing cats anesthetized with sodium pentobarbitone were used. Microinjections of kainic acid into the lateral tegmental field of the ...

Introduction: Pleomorphic adenomas are tumors mostly originating from salivary glands. These lesions in the larynx are very rare. Case Report: We report a rare case of pleomorphic adenoma that originated from the mucosal lining, just above the glottic area at the level of the laryngeal ventricle in a 55-year-old female patient. The tumor could not be palpated easily but was observed in the C...

OBJECTIVES To determine if there are differences in the expressions of the E-cadherin adhesion molecule of precancerous laryngeal lesions classified according to Ljubljana and World Health Organization (WHO) classification. PATIENTS AND METHODS We examined 41 cases (3 females, 38 males; mean age 54 years; range 8 to 80 years) of laryngeal hyperplastic-dysplastic lesions from the Kocaeli Unive...

Introduction. Laryngeal squamous cell carcinoma (LSCC) is the most common SCC of the head and neck. The high incidence of this malignancy and the low survival rate necessitate the development of novel diagnostic approaches. Aim of this study is to compare the diagnostic value of laryngeal brush cytology combined with VEGF immunocytochemistry versus histopathology of clinically precancerous lesi...
