The two mass model (2MM) as introduced by Ishizaka & Flanagan (1972) and simplified by Steinecke & Herzel (1995) describes many features of the vocal fold oscillation patterns [1,2]. Particularly, it was shown that a large variety of voice disorders may be explained by means of high-speed observations with subsequent interpretation by the 2MM. Laryngeal symmetry was identified as an important p...

A 41 year old man with a history of politrauma presented with a nodular mass of the left false vocal cord, associated with progressive dysphonia, dyspnoea, and dysphagia. A computed tomography scan of the neck region showed a rounded and circumscribed mass without infiltration of the surrounding tissues. Histological investigation of the nodule revealed the presence of fibroelastic cartilaginou...

In spite of being the most common nonepithelial neoplasm, chondrosarcoma makes up only about 0.2% of all head and neck malignancies and approximately 1% of all laryngeal tumors. Primary laryngeal chondrosarcoma is rare with only 300 cases being reported in literature. Herein, we present a case of 61-year old male who presented with long-standing neck mass. Histopathological exami nation, reveal...

A 56-year-old female with a background of metastatic rectal adenocarcinoma presented with a subglottic mass causing biphasic stridor. Transoral laser microsurgery and the use of fibrin glue prevented the need for tracheostomy. Six months postoperatively there was no evidence of recurrence. Laryngeal metastasis of colorectal adenocarcinoma, although remarkably rare, is perhaps more prevalent tha...

Hitherto voice changes have been regarded as an infrequent complication of thyroidectomy and damage to the recurrent laryngeal nerve has been given as their major cause. Voice function was assessed in 325 patients after thyroidectomy. Permanent changes occurred in 35 (25%) after subtotal thyroidectomy and in 19 (11%) after lobectomy. The commonest cause of voice change appeared to be injury to ...

BACKGROUND A few studies have analyzed the role of lifetime anthropometric measures on laryngeal cancer risk. PATIENT AND METHODS This relation was investigated using a multicentre case-control study from Italy, conducted between 1992 and 2000, and including 460 incident, histologically confirmed laryngeal cancer cases, and 1088 controls admitted to the same network of hospitals as cases for ...

Sarcoidosis can affect the larynx as a manifestation of systemic disease or as isolated laryngeal involvement. Classically, laryngeal involvement affects the supraglottis, and less commonly the subglottis, and true vocal fold involvement is rare. The clinical course is often highlighted by frequent exacerbations and remissions that, when associated with vague complaints and constitutional sympt...

OBJECTIVES/HYPOTHESIS To describe the demographics, clinical manifestations, diagnosis, treatment, and outcomes of laryngeal cryptococcosis. Antifungal therapy guidelines are provided and the use of laser ablation is discussed. DATA SOURCES PubMed, OVID MEDLINE, and Embase databases and one patient who presented to our institution's otolaryngology department. REVIEW METHODS A review of the ...

UNLABELLED We studied the effectiveness of the intubating laryngeal mask airway (ILMA) in morbidly obese patients scheduled for bariatric surgery. We included 118 consecutive morbidly obese patients (body mass index, 45 +/- 5 kg/m(2)). After the induction of general anesthesia, the laryngeal view was classified by the first observer according to the method of Cormack and Lehane. The ILMA was th...

This study, focused on the laryngeal source level, introduces the concept of laryngeal vibratory mechanism. Human phonation is characterized by the use of four laryngeal mechanisms, labeled M0-M3, as evidenced by the electroglottographic (EGG) study of the transition phenomena between mechanisms with a population of men and women, trained and untrained singers. Macroscopic and local description...
