    Opis:
    Introduction: CO2 laser endoscopic cordectomy is the method of laryngeal cancer treatment. The type of cordectomy (I–VI) depends on the extent of the tumor. Endoscopic laser surgery provides more satisfactory phonation conditions in comparison to open surgical procedures. The aim: The aim of the study was to classify phonatory compensation mechanisms after CO2 laser cordectomy using the HSDI. M aterial and methods: The study included 30 men treated and diagnosed at the Department of Otolaryngology and Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. The control included 30 men with no pathological changes in the larynx. Type III, IV and Va CO2 laser cordectomy have been for glottis cancer treatment. Postoperative evaluation has been conducted 6 months after the surgery. HSDI has been used in larynx visualization. R esults: Type I compensation occurs most frequently in patients after type III cordectomy. Advanced glottis cancer, as an indication for type IV and V cordectomy, leads to epiglottic hyperfunction and phonation involving vestibular folds – type II and III compensation. Type IV compensation is most frequent in type IV cordectomy. C onclusions: The type compensation is connected with the extent of glottis resection. In cordectomy including anterior commissure and the part of opposite fold (type Va), supraglottic hyperfunction with the participation of vestibular folds (type II and III compensation) has been recorded. Transmuscular cordectomy (type III) most often resulted in type I compensation. Type III-Va cordectomy caused reduction or absence of MW, decrease in amplitude and aperiodicity of vibrations in HSDI.

    Opis:
    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.

    Introduction: The laryngeal cancer is the most frequently diagnose malignancy in head and neck region. The highest morbidity is within male patients in the age range between 50 and 70 years. The multicenter study, coordinated by Oto-laryngology Department of Medical University of Warsaw, was designed to investigate the epidemiology of laryngeal cancer in Poland from 1980 and to analyze the evolution of diagnostic and therapeutical procedures over the years.Material and methods: There was performed retrospective analysis of the medical records of patients with laryn-geal cancer hospitalized and treated in 12 otolaryngology centers in Poland from 2001 to 2010. The Microsoft Access 2003 (SP 2) platform was used to collect the data and subsequent statistical analysis.Results: There were collected data from 4124 patients, 3682 men (89,3%) and 442 women (10,7%). The largest group consisted of patients in the age range between 50 and 60 years (41,5%) and the second large group was of those be-tween 60 and 70 years (29,6%). The history of heavy cigarettes smoking was obtained from 81,3% of patients. Re-garding the staging of laryngeal cancer, there were 1634 patients with cancer stage of I or II, including 5 patients with carcinoma in situ and 2490 patients with III or IV stage. The most frequent localization of the cancer was the glottis, followed with invasion of all three laryngeal levels and tumors occupying both the epiglottis and glottis. The major-ity of patients – 1367 (33%) – has the T3 tumor advancement. The lymph nodes metastases (N) were present in 1216 (29,5%) patients and among them the N2b and N2c advancement ( lymph node larger than 6 cm, multiple) was de-tected in 533 of patients (13%). The lymph nodes involvement occurred in majority within advanced tumors of T3 or T4a. Considering the treatment options they varied depending on the staging of laryngeal cancer. The sole surgical procedures were performed in 73,7% of patients with cancer stage of I or II and in only 28.6% of patients with the stage of III or IV. The advanced tumors were in majority treated with the combined therapy: surgery and radiotherapy. The overall survival in patients with cancer stage of I and II was 64% and 61% for those with stage III and IV.Conclusions: The rate of laryngeal cancer detection is quite high in Poland, however the period from the onset of symptoms until diagnosis should be reduced. The effectiveness of surgical treatment is definitely unsatisfactory. The project to create a multicenter permanent base for monitoring the course of diagnosis and treatment in patients with laryngeal cancer surely will verify the procedures and enable to achieve better results. Continuation of this project is a task for all otorhinolaryngologists.KEYWORDS:laryngeal carcinoma, epidemiology, clinical characteristics, multicenter study
