Introduction: Treatment of glottis cancer, despite oncological safety, should consider postoperative voice quality. CO2 laser endoscopic cordectomy allows radical removal of the tumor while maintaining respiratory, defensive and phonatory functions. The aim: The aim of the study is perceptual and acoustic evaluation of voice in patients after endoscopic CO2 III–Va laser cordectomy due to glottis cancer. Material and method: The study included 30 men after CO2 cordectomy. 13 (43%) patients underwent type III cordectomy, 6 (20%) – type IV; 11 (37%) – type Va. Voice quality has been assessed 6 months after the surgery. Control group included 30 healthy men of the same age. GRBAS scale has been used in perceptual evaluation of voice. Acoustic analysis has been performed using DiagnoScope Specjalista software. Narrowband spectrography and Maximum Phonation Time (MPT) measure has been performed. Results: In study group, voice has been classified as G1R1B0A0S0 after type III cordectomy; as G1R1B1A1S2 in type IV and as G2R1B1A0S3 in type Va. Acoustic evaluation revealed the highest values of F0, Jitter, Shimmer and NHR after Va cordectomy as well as non-harmonic components in narrowband spectrography and reduction of MPT. Conclusions: Postoperative voice quality depends on the type of cordectomy. Perceptual assessment indicates that type IV and Va cordectomy cause intensification of voice disorders. Parameters of acoustic evaluation increase with the extent of the procedure. The presence of non-harmonic components in narrowband spectrography increases with the extent of cordectomy, such as the reduction of MPT. Preservation of anterior commissure influences good voice quality in perceptual and acoustic assessment.

Medialization thyroplasty (type I) is surgical procedure performed on the thyroid cartilage. The major indication for this surgery is significant glottis insufficiency due to unilateral vocal fold paresis. However the proce¬dure is also performed after vocal fold resections during cordectomy. The aim: The evaluation of voice results in patients after medialisation throplasty. Material and methods: In Otolaryngology Department of Medical University of Warsaw there were performed so far 8 thyroplasty procedures under local anaesthesia with implantation of medical silicon protesis. 6 patients had unilat¬eral vocal fold paresis and the rest two underwent in the past laser cordectomy due to T1a vocal carcinoma. Results: There were no complications during and post the surgery. The follow up examination in 1st , 3rd, 6th i 12th months postoperatively revealed for all patients significant improvement of glottal closure in laryngeal videostrobos¬copy. The voice quality improved both in perceptual evaluation (GRBAS scale) and acoustic analysis (F0, jitter, shim¬mer, NHR) in both patients groups. However the rate of improvement was much more significant in group with uni¬lateral vocal fold paresis. In all patients the maximum phonation time (MPT) increased. The self-evaluation of voice quality with Voice Handicap Index questionnaire confirmed also individual improvement. Conclusions: The speech rehabilitations is not successful in each patient with glottis insufficiency. The medialisation thyroplasty remains the standard procedure for permanent improvement of voice quality in those cases.

Introduction: Voice dysfunction is the most common complication of thyroid surgery. The use of intraoperative neuromonitoring (IONM) is to protect the recurrent laryngeal nerves, the damage of which causes voice dysfunction. Aim: The aim of the study was to evaluate voice quality in patients who underwent complete thyroidectomy operated on with the application of IONM as well as a group of patients operated on with only macroscopic nerve visualization. In the analysis, clinical voice assessment was performed with particular focus on voice efficiency using the Voice Handicap Index (VHI), Vocal Tract Discomfort (VTD) and GRBAS scale. Material and methods: The study group consisted of 205 patients operated on with IONM. The control group consisted of 162 patients subjected to surgery only with macroscopic visualization of recurrent laryngeal nerves, without IONM. During the follow-up period from 2 to 10 years after surgery, checkups were performed. Each patient who came for a checkup was subjected to perceptual voice evaluation with the use of the GRBAS scale, indirect laryngoscopy procedure and voice selfevaluation with two questionnaires (VHI and VTD). Results: The frequency of vocal fold palsy did not differ significantly statistically in the study group and the control group. Both in the study group and in the control group, patients with vocal fold paralysis had statistically significantly higher results in the VHI and VTD questionnaires as well as in the GRBAS study. Conclusion: Patients with recurrent laryngeal nerve injury show significant differences in the scope of voice handicap, both in the voice quality assessment with the use of the GRBAS scale, and self-evaluation questionnaires: VHI and VTD. All voice disorders evaluated with self-assessment are medium voice disability
