Benign vocal fold lesions are common in the general population, and have important public health implications and impact on patient quality of life. Nowadays, phonomicrosurgery is the most common treatment of these lesions. Voice therapy is generally associated in order to minimize detrimental vocal behaviours that increase the stress at the mid-membranous vocal folds. Nonetheless, the most app...

We present in-vivo 3D human vocal fold images with polarization sensitive optical coherence tomography (PS-OCT). Characterizing the extent and location of vocal fold lesions provides useful information in guiding surgeons during phonomicrosurgery. Previous studies showed that PS-OCT imaging can distinguish vocal fold lesions from normal tissue, but these studies were limited to 2D cross-section...

INTRODUCTION  Dysphonia is the main symptom of lesions that affect the vocal tract. Many of those lesions may require surgical treatment. Polyps are one of the most common forms of vocal cord lesions and the most prevalent indication for laryngeal microsurgery. There are different types of polyps, and their different characteristics can indicate different prognosis and treatments. AIM  To con...

In this paper we present novel approaches for the computer aided diagnosis of leukoplakia on the vocal folds based on video endoscopic images of the larynx. The approaches applied for the classification of the vocal fold surface tissue are texture analysis methods, which have been enhanced to use spatial information as well as color information in one combined color texture approach. The multis...

Elderly patients present deterioration in voice quality due to anatomical and functional changes of the larynx associated with the aging process, and other voice disorders common in the elderly population. Identified causes of geriatric voice dysfunction include anatomic changes in the larynx such as vocal fold atrophy, central neurologic conditions (e.g. stroke, Parkinson’s disease, essential ...

BACKGROUND Vocal fold hyperplastic lesions are premalignant lesions that can be treated effectively by removal of the lesions surgically. AIMS The aim of this study was to discuss the success of surgery in patients with vocal fold hyperplastic lesions in terms of preserving vibratory function by comparing the preoperative and postoperative videolaryngostroboscopy findings. STUDY DESIGN The ...

About two thirds of laryngeal cancers originate at the vocal cords. Early-stage detection of malignant vocal fold alterations, including a discrimination of premalignant lesions, represents a major challenge in laryngology as precancerous vocal fold lesions and small carcinomas are difficult to distinguish by means of regular endoscopy only. We report a procedure to discriminate between maligna...

BACKGROUND Vocal fold polyps are benign nonneoplastic lesions thought to occur as a result of vocal abuse, misuse, or overuse. Similar to vocal fold nodules and cysts, these lesions result in significant disability, especially among those who require voice for their vocation. Current treatment includes conservative (i.e., nonsurgical) and surgical approaches. Most laryngologists agree that cons...

A discrete network of forebrain nuclei underlies vocal learning and production in male zebra finches. Three nuclei within this network form a neural pathway that is particularly important for vocal learning in juveniles: area X of the avian striatum projects to the medial dorsolateral nucleus of the anterior thalamus (DLM), which in turn projects to the lateral magnocellular nucleus of the ante...
