cze	Medializační tyreoplastika pomocí silikonového implantátu.	Autoři hodnotí medializaci hlasivky pomocí silikonového implantátu u 43 operací (36 nemocných) v letech 1999 ? 2003). U 5 nemocných byl výkon kombinován s krikotyreoidní subluxací nebo addukcí arytenoidní chrupavky. Pooperační u 36 nemocných vymizely předoperační potíže, 5 nemocných bylo zlepšeno, a pouze 2 nemocní měli hlas bez změny. Průměrný fonační čas před operací byl 6,5 s a po operaci 12,5 sekund. Jiter poklesl z 5,3 na 3,7 % a shimmer z 32,3 na 18,6 %. Rozdíly byl statisticky významné. Tyreoplastika pomocí silikonového bloku je vhodná metody v léčbě obrny hlasivky.
eng	Medialization thyroplasty with a customized silicon implant: Clinical experience	The authors implemented medialization thyroplasty with a customized silicon implant in a total of 43 operations (36 patients) in 1999 - 2003. In 5 of these patients, the medialization thyroplasty was combined with cricothyroid subluxation (3 cases) or adduction of arytenoid cartilage (3 cases). One patient received together medialization thyroplasty, cricothyroid subluxation and adduction of arytenoid cartilage. During the postoperative subjective evaluation 36 patients reported substantial reduction of their complaints, five patients found their voice improved and only two patients (5.6%) stated that their voice did not change. The subjective evaluation was, consistent with the findings of laryngoscopy and the preoperative and postoperative phonation parameters (maximum phonation time, maximum sound pressure level - SPL, jitter and shimmer). The average maximum phonation time was 6.5 sec before surgery and 12.5 sec after surgery. The maximum SPL of voice was, on average, about 4 dB higher after surgery. Jitter was reduced from 5.3% to 3.7% and shimmer from 32.3% to 18.6%. The differences between all presurgical and postsurgical parameters in our study were all statistically significant, indicating voice improvement. Medialization thyroplasty with a silicon implant was proven to be a successful and safe surgical method for the treatment of vocal fold paralysis.
