laryngeal compensation - 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.
