Abstract
Our aim was to obtain an objective evaluation of the airway before and after glottis-dilating operations utilizing lung function tests. The charts of 109 patients who underwent either reversible or irreversible glottis-dilating operations by Lichtenberger were reviewed. 64 non-selected cases of these patients, all with irreversible glottis-dilating operations, were studied. Lung function tests that were performed were body-pletysmography, forced inspiratory volume (FIV1), forced expiratory volume (FEV1), peak inspiratory flow rate (PIF), peak expiratory flow rate (PEF) and resistance of the airways (RAW). The FEV1, FIV1, PEF and PIF all improved following irreversible glottis-dilating operations. The RAW was remarkably decreased post-operatively as compared to pre-operatively. In conclusion, the airways of patients undergoing irreversible glottis-dilation operations improved moderately to well following such surgeries. Lung function tests are an objective means of evaluating the airway before and after surgery.
