[The systems of classification of laryngo-tracheal stenosis].

Laryngo-tracheal stenosis (LTS) is a relatively rare disease, which develops in very heterogenous group of patients. Careful diagnostics and classification are essential for planning the following treatment and assessing its results. To classify and treat LTS, endoscopic and imaging techniques are required. In this publication basing on the literature review different systems of LTS classifications are described in details. Additionally basing on our clinical experience the probe of choosing the best classification for Polish ENT and thoracosurgery departments was undertaken. In our opinion the use of complex grading systems is unreal in everyday work by Polish ENT surgeons and thoracosurgeons. We suggest to implement the Cotton's system and Medical Research Council dyspnea scale as the optimal way to classify and asses the outcomes of LTS treatment. The former system is well known and widely advocated in Poland, the latter requires a modicum of time from the physician. Both scales, as a combination of subjective and objective parameters show a strong correlation and therefore complement each other.
