Modeling a leaky glottis. [PDF]
The Journal of the Acoustical Society of America, 1992 During the last decade, awareness has grown that the glottis does not necessarily close completely during normal phonation. To what extent a glottal leak affects the glottal flow waveform, however, is still poorly understood. A speech production model is implemented that is capable of simulating source/tract interaction using a time-varying glottal ...

Plain Radiographic Analysis of Laryngeal Dimensions in Young Children: Normal versus Croup
Children, 2022 (1) Background: Contrary to a tenet of the funnel-shaped pediatric larynx with the cricoid level being narrowest, recent studies show the glottis and subglottis as the narrowest levels.

Aerodynamics of the Pseudo-Glottis [PDF]
Folia Phoniatrica et Logopaedica, 2009 <i>Objective:</i> The aim of this work is to study the hitherto unclear aerodynamic parameters of the pseudo-glottis following total laryngectomy. These parameters include airflow rate, sub-pseudo-glottic pressure (SubPsG), efficiency and resistance, as well as sound pressure level (SPL).

Frontiers in Zoology, 2012 Background The avian glottis channels air from the oropharynx to the trachea and is situated on an elevated structure, the laryngeal mound. It is imperative that the glottis be protected and closed during swallowing, which in mammals is achieved by ...

Predictors of chemotherapy and its effects in early stage squamous cell carcinoma of the larynx
Laryngoscope Investigative Otolaryngology, 2020 Background Squamous cell carcinoma (SCC) of larynx is a common head and neck cancer. For cases that are node negative, the role of definitive concurrent chemoradiation is unclear and not supported by guidelines but used at provider discretion. To address

Clinical significance of matrix metalloproteinase (MMP)-2 and MMP-9 expression in laryngeal squamous cell carcinoma [PDF]
Vojnosanitetski Pregled, 2021 Background/Aim. The previous researches suggest that matrix metalloproteinases (MMPs) have the ability to degrade extracellu-lar matrix components and play an important role in malignant tumour progression and metastasis.

Oral Endotracheal Intubation with Restricted Glottis View using C-MAC D Blade®: A Randomised Controlled Trial [PDF]
Journal of Clinical and Diagnostic ResearchIntroduction: The perspective of airway management has undergone a considerable transformation since the advent of Video Laryngoscopes (VL). VL has rapidly been accepted as an intubation tool in a variety of clinical scenarios.

Indian Journal of Anaesthesia, 2010 Successful endotracheal intubation requires a clear view of glottis. Optimal external laryngeal manipulation may improve the view of glottis on direct laryngoscopy with Macintosh blade, but it requires another trained hand.

Ultrasonographic Estimation of Endotracheal Case Series Tube Size in Paediatric Patients and its Comparison with Physical Indices Based Formulae: A Prospective Study [PDF]
Journal of Clinical and Diagnostic Research, 2017 Introduction: Choosing the correct Endotracheal Tube (ETT) size is important in paediatric anaesthesia. The subglottic diameter being the narrowest diameter of the paediatric upper airway plays an important role in appropriate ETT size selection. Aim:
