[Usefulness of ventilation tests in the diagnosis and evaluation of treatment results in select laryngeal diseases].
The obstruction of upper airways is a common symptom of some laryngological diseases. The patients need exact diagnosis and proper treatment. The ventilation tests seem to be one of the most important tool in process of diagnosis and treatment, however they are more pulmonological than laryngological procedures. The aim of the study was to evaluate the efficacy of ventilation tests and analysis of their interpretation in patients with laryngeal and/or tracheal obstruction. Also, we intended to show a method of spirometric examination in patients with tracheostoma. Based on our common clinical experience (more than 3000 tests in patients with upper airways obstruction in ENT Departments in Zabrze and Szczecin) we presented our observations. In majority, the tests were used in patients after laryngeal surgery due to the cancer or bilateral vocal cord paralysis and in patients with tracheostomy, before decannulation. The attention was paid on usefulness of some coefficients, especially in diagnosis of upper airway obstruction. For better results interpretation the authors introduced the term of mixed obstruction in contrast to fixed and dynamically variable narrowing. Also the FIV1/N FEV1 parameter was purposed. In conclusion the great role of ventilation tests was emphasized, especially in diagnosis of the narrowing on the larynx and trachea level and also in evaluation of the results after surgical procedures on upper airways.
