The Study Of Two Repairing Modes On The Voice Of T₂ Glottic Carcinoma

Objects: Laryngeal carcinoma is the most commom tumor of otolaryngology. The operative amputate is still the first choice in carcinoma treatment. But post - operative voice's losing is still challenge for head and neck surgeon. laryngeal carcinoma treatment transfer function of reconstruction , elevate patient's quality of life. Many methods about ponation reconstruction have been recommended, but only few are refred to the ponation rehilitition at home and abroad. The study carry out objective evaluation of laryngeal repairing modes of vocal function of laryngeal cavity after vertial hemilaygectomy .Method: We chosed randomly from 32 patients with glottic carcinoma undergone vertical hemilarygectomy in HNO of the first hospital of Shanxi Mdical University and otolaryngology department of Shanxi Cancer Hospital from June 2006 to November 2006.All objects were analysised voice of preoperative,three months and six months after operation with Dr. speech Voice Assessment systemResults: 1.Following result: 17 patients with sterhoyoid muscle flap, 15 patients with thyroid perichodrium. After operation, 5 patients with sterhohyoid muscle flap occurance aspiration, 3 patients with thyroid perichodrium occurance aspiration, All patients with two restorative procedures have pronunciation well. Patients with srerhohyoid muscle flap fissure of goltts >0.6 cm, patients with thyoid perichodrium fissure of goltts >0.8 cm. 2.Acousic analysis (1)Jitter,Shimmer and NNE of phonation reconstruction with sterhohyoid muscle flap or thyroid perichodrium cxceed preoperation's in three months after operation, especially, Jitter,Shimmer and NNE with phonation reconstruction thyroid perichodrium.(2) Jitter,Shimmer and NNE of phonation reconstruction with sterhohyoid muscle flap or thyroid perichodrium exceed preoperation's in six months after operation, especially, Shimmer and NNE with phonation reconstruction thyroid perichodrium.(3) Jitter and NNE phonation reconstruction with sterhohyoid muscle flap smaller phonation reconstruction phonation reconstruction with thyroid perichodrium.Conclusions: (1) Acousic analysisis of glottic carcinoma undergone vertical hemilarygectomy with sterhohyoid muscle flap is better with thyroid perichodrium.(2) Acousic analysisis of T2glottic carcinoma undergone vertical hemilarygectomy with sterhohyoid muscle flap and with thyroid perichodrium six months after operation is better three months after operation, voice gradually recover. (3) Voice after T₂glottic carcinoma the softmare of acousic analysis is good in study short time...
