  • Title: [Disorder types of the larynx airflow in patients after partial laryngectomy: objective examination].
    Author: Matyja G.
    Journal: Otolaryngol Pol; 2000; 54 Suppl 31():73-6. PubMed ID: 10974848.
    Abstract:
    223 spirometric examinations, 144 laryngovideoscopic examinations and 43 CT of the larynx in 70 patients after partial laryngectomies of various extents were analysed. The shape of the flow volume curve was divided in 3 kinds of larynx obturation: fixed, dynamically variable and mixed (with characteristics to both). Factors depending on larynx influence the dimension of the obturation (surface and length of the contraction and also stiffness of the walls) as well as numerous extra laryngeal factors do, independently of the contraction itself. On the base of the parameters and the shape of the flow volume loop the volume flow capacity can be estimated (helpful in estimation of the respiratory sufficiency of the patient), the kind of the obturation (resulted from stiffness of the scar or elasticity of the walls), probable spot of the contraction (obturation of the larynx or bronchial narrowing), changes of the obturation in course of time (specific for the healing process or for developing complications). The results obtained were compared with the laryngovideoscopy, radiological examination and (in several cases) with the interoperative assessment. Great measure of conformability of the spirometric diagnostics with the above mentioned investigations was found. The usefulness of those investigations in the after care of the patients following partial laryngectomies was stressed, as well as in making decision for eventual reoperation and also economic advantages.
