Airway Glottic Insufficiency - StatPearls - NCBI Bookshelf
2023年9月13日 · Airway glottic insufficiency is characterized by incomplete closure of the vocal folds during phonation, resulting in an increased risk of aspiration and the development of laryngeal symptoms such as dysphonia and dysphagia.
terior glottic chink is the opening between the cords and the size of the glottic chink is important in respiration and phonation. The human larynx has several highly complex functions: it must close to protect the airway from life-threatening aspira-tion, but must open fully during exercise to optimise airflow and thus exercise perfor-
Differences Between Flexible and Rigid Endoscopy in Assessing the ...
The posterior glottic chink (PGC) is defined as a posterior triangular gap extending from the posterior wall of the glottis to the tip of the vocal processes present on maximal closure of the glottis. The glottic chink is believed to be found most commonly in females, and males.
Visual-perceptive assessment of glottic characteristics of vocal ...
Glottal closure is characterized by the presence of a mid-posterior triangular chink (double chink or isolated mid-posterior triangular chink), without movement of supraglottic laryngeal structures, with irregular contour of the free edge of vocal folds, which are vertically on-plane.
Modeling the effects of a posterior glottal opening on vocal fold ...
The effects of a posterior glottal gap on the glottal aerodynamics, energy transfer, tissue dynamics, and resulting acoustics were numerically investigated using a specially designed flow solver and a reduced-order model of human phonation.
Options for treatment of a small glottic gap - PMC
When surgery is chosen, closure of the glottic gap is the primary goal. Options for surgical management include injection medialization, thyroplasty, and other methods of medializing the vocal folds. This manuscript reviews the current literature regarding the …
Differences in Glottal Closure and Visibility of the Anterior ...
A posterior glottal chink, if only in the intercartilaginous or extending to the intermembranous part, was stated to be a normal physiologic finding in young women for no increased breathiness was detected. These findings can mainly be explained by gender-specific anatomical differences.
Vocal Cord Dysfunction - an overview | ScienceDirect Topics
In VCD, the vocal cords adduct anteriorly from the vocal process, and the posterior glottic chink remains open. The adduction occurs during inspiration or in both the inspiratory and expiratory phases.
Understanding Vocal Cord Dysfunction - CHEST
To summarize, when laryngoscopy is performed utilizing adequate topical anesthesia in symptomatic patients, the presence of inspiratory or inspiratory and expiratory vocal cord adduction with a posterior glottic chink confirms the diagnosis of VCD. The findings are illustrated in …
Differences between flexible and rigid endoscopy in assessing …
Objective: To determine whether different modalities of laryngeal examination produce differences in the assessment of the posterior glottic chink (PGC), and whether the prevalence of PGC differs by gender.
