In general, the most common and quantifiable limitation is dyspnea, initially occurring with exertion. BronchAtlas Extent of Tracheal Stenosis. Functional limitation in LTS has been assessed with the Medical Research Council MRC dyspnea scale, which grades dyspnea fromwith higher scores indicating more severe dyspnea; this tool was shown subglotida have excellent inter-observer correlation in a variety of respiratory diseases8.

The work of breathing depends on the pressure change along the stenotic segment, and is influenced by both the degree of obstruction and the velocity of flow through the Laryngotracheal stenosis segment. Annals of Otology Rhinology and Laryngology ; Description of a multidimensional classification system for patients with expiratory central airway collapse.

LTS does not include exophytic endoluminal obstruction or extrinsic compression from histologically benign or malignant disease, but rather refers to the development of hypertrophic, histologically benign stenotic tissues resulting in airway stricture.

The objective of this article is to clarify the relevant parameters that need to be considered in the evaluation of patients with LTS. Functional Impairment Functional limitation attributable to the stenosis must be objectively assessed as patients may have only mild symptoms or be completely asymptomatic in which case treatment minimally invasive or surgical is not indicated.

The American Journal of Surgical Pathology ; Resection of distal tracheal stenosis in a baby with agenesis of the lung. Spirometry and flow volume loops are helpful in evaluating airflow limitation and documenting improvement following interventions, but the classic pattern of truncation of inspiratory and expiratory limbs on the flow volume loop, typically associated with central and upper airway stenosis, lacks sensitivity and is usually seen only when the tracheal lumen is already reduced to mm7.
