Glottic

When the scarring from subglottic stenosis is limited to the back part of the vocal cords (inter-arytenoid region), it is called posterior glottic stenosis. ❋ Unknown (2010)

The catheter should be of a size, relative to that of the glottic chink, to permit a free return-flow. ❋ Chevalier Jackson (1911)

Cicatricial types of postdiphtheritic stenosis may be seen as webs, annular cicatrices of funnel shape, or masses of fibrous tissue causing fixation of the arytenoids as well as encroachment on the glottic lumen. ❋ Chevalier Jackson (1911)

_Edema of the larynx_ may be at the glottic level, or in the supraglottic or subglottic regions. ❋ Chevalier Jackson (1911)

-- If withdrawal be made a bimanual procedure it is almost certain that the foreign body will trail a centimeter or more beyond the tube mouth, and that the closure of the glottic chink as soon as the distal end of the bronchoscope emerges will strip the foreign body from the forceps grasp, when the foreign body reaches the cords. ❋ Chevalier Jackson (1911)

In this position it will be found that the tip of the slanted end is in the center of the glottic chink and will slip readily into the trachea. ❋ Chevalier Jackson (1911)

When these mechanisms are impaired, as in profound asthenia, laryngeal paralysis, laryngeal or tracheal stenosis, etc.; and especially when in addition to a mild degree of glottic stenosis or impaired laryngeal mobility, the secretions become excessive, the accumulation may literally drown the patient in his own secretions. ❋ Chevalier Jackson (1911)

Its shape allows its introduction into the vestibule of the larynx, and if desired it may be introduced through the glottic chink for the treatment of subglottic conditions. ❋ Chevalier Jackson (1911)

In doing this, the amount of secretion and the handicap of impaired glottic mobility in the expulsion of thick secretions must be borne in mind. ❋ Chevalier Jackson (1911)

B will rip open the esophagus or bronchus inflicting fatal trauma, and probably the pin will be stripped off at the glottic or the cricopharyngeal level, respectively. ❋ Chevalier Jackson (1911)

Care must be taken to rotate the pin so that it lies in the sagittal plane of the glottis with the keeper placed posteriorly, for the reason that the base of the glottic triangle is posterior, and that the posterior wall of the larynx is membranous above the cricoid cartilage, and will yield. ❋ Chevalier Jackson (1911)

In the selection of tubes it must be remembered that the full diameter of the trachea is not available on account of the glottic aperture which in the adult is a triangle measuring approximately 12 X 22 X 22 mm. ❋ Chevalier Jackson (1911)

The respiratory rate naturally increases because of air hunger, accumulating secretions that cannot be expelled because of impaired glottic motility give signs wrongly interpreted as pneumonia. ❋ Chevalier Jackson (1911)

Not bringing the greatest diameter of the foreign body into the sagittal plane of the glottic chink. ❋ Chevalier Jackson (1911)

Crying and possibly glottic spasm increase the difficulties. ❋ Chevalier Jackson (1911)

In almost all cases, ventriculocordectomy will result in a sufficient increase in the glottic chink for normal respiration. ❋ Chevalier Jackson (1911)

The fundamental principles are that a pointed object must either have its point protected by the forceps grasp or be brought out point trailing, and that a flat object must be so rotated that its plane corresponds to the sagittal plane of the glottic chink. ❋ Chevalier Jackson (1911)

This position was necessary for it to pass through the glottic chink, and can be maintained because of the yielding of the posterior membranous wall of the trachea. ❋ Chevalier Jackson (1911)

If, however, as in cases of arachidic bronchitis, large amounts of purulent secretion must be expelled, it will be found in certain cases that the decreased glottic lumen and impaired laryngeal motility will render tracheotomy necessary to drain the lungs and prevent drowning in the retained secretions. ❋ Chevalier Jackson (1911)

Tracheotomy is necessary however, because of the reactionary swelling, which may be so great as to close completely the narrowed glottic chink. ❋ Chevalier Jackson (1911)
