      ABSTRACT = {Phonus 4, Institute of Phonetics, University of the Saarland, 1999, 103-121. In this paper the course of the therapy after minimally invasive laser surgery for a carcinoma of the vocal cord (T1) is evaluated using acoustic and electroglottographic methods. The evaluation includes preoperative, postoperative and post-rehabilitative conditions. With the help of frequency and amplitude perturbation parameters derived from the acoustic output, and parameters based on electroglottographic properties of single periods (contact and skewing quotient; jitter), respectively, we are able to provide statistical evidence for the effectiveness of the therapeutic measures. Comparisons with the tolerance values given by the producers of the analysis programs and with empirically derived variation ranges from a large sample of normal speakers allow us to quantify the effect. The course of the recovery, also described in this study, provides the anatomical and physiological basis to explain the functional improvement of phonation observed in the acoustic and electroglottographic correlates.},
