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 ct s...

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...

Atypical Carcinoids, Malignancy arising from neuroendocrine cells are among the non-Epidermoid cancers of larynx.The present study reports an interesting and rare case of atypical carcinoid of larynx. An 85-year-old male patient presented with a history of dysphagia.On clinical examination, a provisional diagnosis of cyst larynx was made. But during surgery, the Diagnosis had to be reviewed as ...

In this work, we evaluate laryngeal ultrasound as a technique to study the state and height of the larynx. We first discuss general structural registration in laryngeal ultrasound (LUS) and illustrate the articulation of glottal stop. We then present a method for quantifying change in larynx height using optical flow analysis on laryngeal ultrasound video data. The analysis is quantitatively va...

Optical coherence tomography (OCT) is an evolving noninvasive imaging modality and has been used to image the larynx during surgical endoscopy. The design of an OCT sampling device capable of capturing images of the human larynx during a typical office based laryngoscopy examination is discussed. Both patient's and physician's movements were addressed. In vivo OCT imaging of the human larynx is...

PURPOSE To develop a clinical practice guideline for treatment of laryngeal cancer with the intent of preserving the larynx (either the organ itself or its function). This guideline is intended for use by oncologists in the care of patients outside of clinical trials. METHODS A multidisciplinary Expert Panel determined the clinical management questions to be addressed and reviewed the literat...

Rhabdomyosarcoma of the larynx is an extremely rare disease. To date of the literature has been described only about 70 cases of rhabdomyosarcoma of the larynx, including the adult population — 39 cases. There is very little information about the clinical presentation and course of rhabdomyosarcoma of the larynx. The article presents a review of the literature and our own observations of the di...

Phonatory control by laryngeal movement is discussed by summarizing our two previous studies regarding the role of vertical larynx movement based on magnetic resonance imaging (MRI) observation. The first study focuses on a fundamental frequency (F0) control mechanism involving vertical larynx movement. Mid-sagittal images were recorded during vowel productions with a descending musical scale. ...

BACKGROUND The aim of the study was to evaluate the presence of cagA gene Helicobacter pylori in etiopathogenesis of initiation and development of larynx squamous cell carcinoma (LSCC) and its predictable role as a prognostic factor. MATERIAL AND METHODS The prospective, controlled study involved a series of 75 patients (65 male, 10 female, mean age 59.1 years, range 43 to 79 years) with lary...

Individual variation of larynx position reflects human morphological differences and thus contributes to generating biological information in speech sounds. This study examines the factors of orofacial morphology that co-vary with larynx position based on MRI data collected for 12 Japanese and 12 English speakers. The materials are midsagittal craniofacial images, and the method is based on the...
