Opis:: 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.

Opis:: Laryngeal reinnervation is the method of treatment in unilateral vocal fold paralysis. During the surgery an anastomosis between the main branch of ansa cervicalis and recurrent laryngeal nerve is formed. Regeneration of the nerve’s functional abilities is a long process, lasting from 4 to 6 months, up to a year. A 35 year-old male was admitted to the Department of Otolaryngology at Warsaw Medical University in order to undergo surgical removal of reoccurrence of Schwannoma in left cerebellopontine angle by translabyrinthine approach. Post-operative period was complicated with vagal nerve paralysis. The patient reported hoarseness, dysphagia and choking. Physical examination revealed left vocal fold immobilization in abducted position, saliva in piriform fossa and left-sided soft palate paralysis yet the patient was discharged home. 4 weeks after the surgery, the patient was admitted to the hospital again due to developing aspiration pneumonia. Augmentation of the left vocal fold with calcium hydroxyapatite was performed 2 months later. After this intervention temporary vocal improvement and choking frequency reduction was observed. Finally, the patient underwent laryngeal reinnervation with formation of ansa cervicalis main branch to recurrent laryngeal nerve anastomosis. Left vocal fold regained its functional abilities and the quality of the voice improved. Laryngovideostroboscopy performed 6 months later revealed mobilization of left vocal fold sufficient for proper glottis closure. The voice measures normalized and the swallowing improved. Conclusions This case report and analyzed data confirm that laryngeal reinnervation surgery in unilateral vocal fold paralysis helps achieve satisfactory effects in voice function and life quality.

Opis:: Objective: To assess the sensitivity and specificity of larngovideostroboscopy (LVS) in the diagnosis of precancerous and malignant lesions of the vocal folds. Material and methods: In 175 patients (128 men and 47 women), aged 19-88 years, mean age 61.5, who were admitted to the clinic with diagnosed premalignant conditions of vocal fold mucosa (leukoplakia, chronic hypertrophic inflammatory lesions) and thickening or tumor on the vocal fold, there was performed LVS before the laryngeal microsurgery. The LVS study included: localization of the leasion, movement of the vocal folds, mucosal wave, shape of glottis clousure, amplitude and symmetry of vocal fold vibration. In the evaluation, a point scale was applied for the individual functional parameters. The scale ranged from 0 to 14. Patients with impaired vocal fold motion or absent mucosal wave were positive on LVS for malignant lesions. Those with limitted mucosal wave were positive on LVS for dysplastic lesions. The results were compared with the final histopathological examination and the sensitivity, specificity, accuracy, positive (PPV) and negative (NPV) predictive value were calculated. Results: On the basis of histopathological examination, benign lesions (normal or inflammatory mucosa) accounted for 20% of diagnoses, hypertrophy and parakeratosis for 28%, low and middle grade dysplasia accounted for 10% and malignant lesions (high-grade dysplasia, pre-invasive cancer, Invasive cancer) was diagnosed in 42% of patients. The overall mean score for LVS was 4.5 and 8.0, respectively for benign and malignant lesions. Sensitivity, specificity, accuracy, PPV and NPV of LVS in detecting malignant lesions were respectively - 95.6%, 23.8%, 61.1%, 57.6% and 83.3% and in detecting both premalignant and malignant lesions were respectively – 90.7%, 31.4%, 78.9%, 84.1% and 45.8%. Conclusions: Because of the high sensitivity of LVS in detecting precancerous and malignant lesions, this method is a very good tool for screening of pathology within the larynx.
