Arytenoid edema following radiation therapy of laryngeal cancer may persist and make careful inspection and evaluation of the larynx difficult. Moreover, it may have serious impacts on functions such as breathing, swallowing, speech and voice. Conservative management such as antibiotics and steroid may be attempted but may be ineffective in progressive and severe cases of edema. We present four...

The purpose of this report is to summarize the salient points made during a panel discussion at the 88th Annual Meeting of the American Broncho-Esophagological Association about the efficacy and oncological safety of endoscopic laser treatment of laryngeal cancer. Guidelines for endoscopic laser management of early glottic and supraglottic cancer, including contraindications for this treatment ...

The study presents the first attempt to investigate resonance properties of the living vocal folds by means of laryngoscopy. Laryngeal vibrations were excited via a shaker placed on the neck of a male subject and observed by means of videostroboscopy and videokymography (VKG). When the vocal folds were tuned to the phonation frequency of 110 Hz and sinusoidal vibration with sweeping frequency (...

A combination of dissection and computed tomography scanning has provided significant novel insights into the structure and function of the Dermochelys coriacea larynx and its associated muscles. Several previously unknown features of the laryngeal aditus (glottis) are described and their functional significance in its opening and closure are considered. The tongue plays an essential part in pr...

In voice research, in vitro tensile stretch experiments of vocal fold tissues are commonly employed to determine the tissue biomechanical properties. In the standard stretch-release protocol, tissue deformation is computed from displacements applied to sutures inserted through the thyroid and arytenoid cartilages, with the cartilages assumed to be rigid. Here, a non-contact optical method was e...

OBJECTIVES/HYPOTHESIS Perform a systematic literature search to provide an overview of today's literature regarding the different aspects that can cause dysphagia after supracricoid laryngectomy. STUDY DESIGN A systematic literature review. REVIEW METHODS The inclusion criteria were laryngeal cancer, supracricoid laryngectomy, and swallowing. Thirty-one qualifying articles were included and...

Laryngeal adductor responses (LAR) close the airway in response to stimulation of peripheral afferents in the superior laryngeal nerve. Although both mucosal afferents and proprioceptive receptors are present in the larynx, their relative contribution for reflex elicitation is unknown. Our purpose was to determine which receptor types are of importance in eliciting the LAR. A servomotor with di...

The purpose of this study was to evaluate the effect of the canine cranial cruciate ligament repair system on laryngeal hemiplegia in heavy draft horses. Twenty-four heavy draft horses diagnosed with grade 4 laryngeal hemiplegia were allocated to either the prosthetic laryngoplasty (PL) group (n=14) or a canine cranial cruciate ligament repair system (CCCLRS) group (n=10). Right to left angle q...

A modified two-mass model of the vocal folds is introduced and applied to the articulatory synthesis of words in six voice qualities. The modified two-mass model uses mass elements that are inclined, instead of parallel, with respect to the dorsoventral axis as a function of the degree of abduction. This allows to produce the continuum of voice qualities from pressed over modal to breathy voice...
