Descriptions of vocal fold lesions related to autoimmune diseases are rare in the literature, and focus mainly on rheumatoid nodules. This is the first report in which autoimmune diseases were promptly suspected by the observation of a unique white transverse submucosal lesion in the vocal fold during clinical examination. This lesion, reported only in autoimmune disease, has been called the ba...

BACKGROUND Vocal cord leukoplakia comprises a variety of lesions. The purpose of this study was to stratify vocal leukoplakias before surgery. METHODS Patients with an initial diagnosis of vocal leukoplakia who underwent surgical excision at a tertiary referral center in Taiwan were recruited for this study. Their clinical records, including age, sex, preoperative laryngoscopic images in the ...

Diagnosis and treatment of vocal fold lesions has been a long-evolving science for the otolaryngologist. Contemporary practice requires biopsy of a glottal lesion in the operating room under general anesthesia for diagnosis. Current in-office technology is limited to visualizing the surface of the vocal folds with fiber-optic or rigid endoscopy and using stroboscopic or high-speed video to infe...

conclusion non-mass-like lesions, lesions with focal or segmental distribution, with a “plateau” enhancement curve type were the most frequent findings of dcis lesions on mri. background adequate diagnosis of ductal carcinoma in situ (dcis) could lead to efficacious treatment. due to the fact that dcis lesions can progress to invasive carcinomas and that the sensitivity of the standard examinat...

In this study, we focus on the classification of neutral and stressed speech based on a physical model. In order to represent the characteristics of the vocal folds and vocal tract during the process of speech production and to explore the physical parameters involved, we propose a method using the two-mass model. As feature parameters, we focus on stiffness parameters of the vocal folds, vocal...

A 62-year-old woman smoker presented with 1 week of common cold and worsening hoarseness. She presented with dyspnea, which had been worsening over the past few days. On the initial examination in theemergency room, she couldnot liedown, stridor was evident and fiberoptic laryngoscopy revealed large laryngeal mass causing airway obstruction. Large laryngeal mass disappeared in subglottis with i...

OBJECTIVES To pool and meta-analyze the reported outcomes in patients receiving radiotherapy for T2 glottic carcinoma with impaired vocal cord mobility. DATA SOURCES A MEDLINE search and manual search were conducted to identify all studies published between January 1, 1950 and September 30, 2007, in English on the treatment of T2 glottic carcinoma. Search terms included laryngeal neoplasm, gl...

in this study we investigate voice productions of normal speakers and patients with varying vocal fold adduction deficiencies using a noninvasive method to measure spatial vibrations of the larynx. the current version accv4 of our acceleration sensor device was used. The study’s primary goal is to find out whether lesions of vocal folds lead to additional spatial vibration modes compared to a n...

Vocal learning has evolved in only a few groups of mammals and birds. The developmental and evolutionary origins of vocal learning remain unclear. The imitation of a memorized sound is a clear example of vocal learning, but is that when vocal learning starts? Here we use an ontogenetic approach to examine how vocal learning emerges in a songbird, the chipping sparrow. The first vocalizations of...
