| Measure | Time frame |
|---|---|
| Stridor. Timepoint: Before surgery and at intervals of 2 weeks, 2 months, and 6 months after surgery. Method of measurement: Clinical examination of the patient.;Aspiration. Timepoint: Before surgery and at intervals of 2 weeks, 2 months, and 6 months after surgery. Method of measurement: Clinical examination of the patient.;Auditory-perceptual characteristics of sound. Timepoint: Before surgery and at intervals of 2 weeks, 2 months, and 6 months after surgery. Method of measurement: GRBAS scale is used to evaluate audio-perception of sound, which describes Grade, Roughness, Breathiness, Asthenia and Straining in 4 modes (0=no defect, 1=mild defect, 2=moderate defect and 3=severe defect). This index is an expert-oriented index. For this purpose, the voice sample recorded from the patient with the help of headphones for the speech therapist is played according to the mentioned 4-degree scale.;Voice handicap index. Timepoint: Before surgery and at intervals of 2 weeks, 2 months, and 6 months after surgery. Method of measurement: Questionnaire will be filled in three functional, physical and emotional parts in these patients. This questionnaire has 30 questions, and it is provided to the patient and completed by them in each of the assessment phases.;Acoustic characteristics of sound. Timepoint: Before surgery and at intervals of 2 weeks, 2 months, and 6 months after surgery. Method of measurement: Acoustic evaluations include many things that are evaluated in this research. All acoustic evaluations will be done by a speech therapist with the help of PRAAT software. The types of acoustic features are mentioned below. 1- Maximum vocalization time (MPT): to evaluate the maximum ability of a person. It is measured based on seconds using a stopwatch in three times and the average number of times is recorded. 2- Jitter: disturbance of frequency and amplitude of frequency disturbance 3- Shimmer: disturbance of amplitude of oscillation 4- Noise to harmonic ratio (NHR): to che | — |
