Incidence rates for laryngeal cancer in Central Europe are among the highest in the world. The authors recruited cases and controls between 2000 and 2002 for the Central and Eastern Europe Multicenter Study to investigate the role of tobacco and alcohol as causes of laryngeal cancer in this region. A total of 384 incident squamous cell cases were included, comprising 254 glottic and 108 supragl...

OBJECTIVE The aim of this study is to evaluate the value of high resolution ultrasonography (HRUS) in diagnosis of various laryngeal lesions which already diagnosed with rigid endoscopy. STUDY DESIGN Prospective study with control group. PATIENTS AND METHODS Sixty-six patients were suffering from throat symptoms and pre-examined by rigid endoscopy under local anesthesia and diagnosed to hav...

OBJECTIVE The aim of this study is to summarize the experience of intraoperative neuromonitoring system for monitoring and protection of recurrent laryngeal nerve during thyroid surgery. METHODS There were 220 cases in this study, male 53, female 167, mean age 38.2 years old. 85 cases in the study had thyroid cancer, 19 cases had thyroid benign tumor, 90 cases had thyroid goiter, 3 cases had ...

Introduction Premalignant lesions are considered both a hyperplastic and dysplastic stage of epithelial lesions in the glottic larynx that may or may not progress into an invasive carcinoma. The evolution of laryngoscopic procedures in outpatients has provided better access to important information for safe and easy diagnosis of laryngeal pathologies. Objective The goal of this study was to det...

Dear Editor, Recurrent laryngeal nerve (RLN) lies in close proximity with the thyroid gland. Thus, thyroid diseases, mainly the malignant ones, tend to cause irreversible recurrent laryngeal nerve damage due to the infi ltration of the tumour cell. RLN damage due to benign lesion particularly from a solitary thyroid cyst is a rare incident. We report a case of a patient with right vocal cord pa...

Malignant tumors of the larynx are very rare in children. They are often diagnosed late, since the initial symptoms are attributed to the process of larynx development or to other, more common pediatric diseases. Early visualization of the larynx with the aid of flexible or rigid fiberoptic laryngoscopy is essential in children having symptoms suggestive of laryngeal disease. Laryngeal lymphoma...

A method of pitch-synchronous acoustic analysis of hoarseness requiring a voice sample of only four fundamental periods is presented. This method calculates a noise-to-signal (N/S) ratio, which indicates the depth of valleys between harmonic peaks in the power spectrum. The spectrum is calculated pitch synchronously from a Fourier transform of the signal, windowed through a continuously variabl...
