The Phonosurgery Study Of Oesophageal Voice By Speech Aid After Total Laryngectomy And Unilateral Vocal Cord Paralysis

Purpose Laryngeal cancer (carcinomaofthelarynx) is a malignant tumor derivedfrom epithelial tissue of the laryngeal mucosa, laryngeal cancer treatment is surgicalresection of cervical lymph node dissection plus postoperative radiotherapy. Totallaryngectomy surgery is one of the commom methods to treatment advanced laryngealcommon, postoperative ability to pronounce related to confidence in the quality of lifeof patients and survival. In this we Controled Oesophageal Voice by Speech AidAppliance After Total Laryngectomy with unilateral vocal cord paralysis in patientswith voice. We used phonetics to analyze both pronunciation and Furtherunderstanding the new voice of oesophageal voice by speech aid appliance. Method10cases as group of oesophageal voice by speech aid appliance after totalLaryngectomy.10cases of unilateral vocal cord paralysis,10cases of normal controlgroup. Using subjective and objective evaluation analysis the subjects. Results1.Objective indicators:①the subjects detected the base frequency (of F0), subjectsdetect the fundamental frequency perturbation (jitter), the value of the amplitudeperturbation (shimmer) of the subjects detected by statistical analysis of variancebetween groupsanalysis of P <0.05, it is felt that there was significant differenceamong the groups the fundamental frequency perturbation values.②the value of thesubjects detected the maximum phonation time (MPT) statistics: pronunciation groupof esophageal sound to help voice and pronunciation group of unilateral vocal cordparalysis maximum phonation time was significantly lower than the normal voicegroup, significant difference (P <0.01the); group of MPT and vocal cord paralysispronunciation MPT Oesophageal Voice by Speech Aid Appliancevoice pronunciationgroup, the difference was not statistically significant (P>0.05). Mainly distributed the2. GRBAS results: GRBAS in oesophageal voice by speech aid appliancevocal groupgrading level2and3, a small part was level1,no one in level0. Vocal cord paralysis, asmall part of a rating of0, the distribution is mainly in the2,3level. OesophagealVoice by speech aid appliancevocal group rating2,3series than pure vocal cordparalysis group, especially the level3assessment.3. total laryngectomy resection ofOesophageal Voice by Speech Aid Appliancevocal group with vocal cord paralysisgroup Pronunciation group VHI score (functional), P (physiological), E (emotion) andTVH (total score) were statistically significant (P <0.05).4. Oesophageal Voice bySpeech Aid Appliancesound device in patients with G, R, B, between the correlationare high. G, R, B, classification, and jitter, Shimmer indicators, a good correlationwith the MPT for the negative correlation. Conclusion1.An esophageal sound to helpvoice pronunciation baseband lower than normal, and lesions caused by the qualitative change in the vocal organs.2. Oesophageal Voice by Speech AidAppliancevoice pronunciation fundamental frequency perturbation and amplitudeperturbation higher, indicating that the esophagus audio help sound pronunciation stillrougher sound. Patients with Oesophageal Voice by Speech Aid Appliancesounderpronunciation and in patients with unilateral vocal cord paralysis maximum phonationtime was no significant difference, indicating its pronunciation gas flow.4.GRBASsubjective assessment, we found that R, B rating of oesophageal Voice by Speech AidAppliancecompared with unilateral vocal cord paralysis in patients with high,indicating that the normal higher degree of esophageal sound to help patients withsounder overall perceived voice.5. Voice Handicap Index-10(VHI-10) analysis ofesophageal sound to help voice the control group with unilateral vocal cord paralysisgroup F (function), P (physiological), E (emotion) and TVH (total score) werestatistically significant, description of esophageal sound to help sounder patients ownvoice satisfaction is still low.6. oesophageal Voice by Speech Aid Appliancethe sixstudy sound device in patients with G, R, B, classification, and jitter, Shimmerindicators and has a good correlation with the MPT for the negative correlation,indicating that oesophageal voice by speech aid appliancevoice sound quality inpatients with three related;7.The VHI-10voice disturbance index and the G and R, B,jitter, shimmer, correlation is relatively high,so in oesophageal voice by speech Aid, G,R, B, Voice instability and irregular effects are closely related. These results,indicating the sounder pronunciation of oesophageal voice by speech aid solve theproblem of relatively traditional occurrence of esophageal tone shorter, significantlyimproved the reconstruction of patients with no throat sound, but contrast in patientswith unilateral vocal cord paralysis are still gaps, their main difference lies insensitive throat roughness is higher in patients with lack of sound precisionadjustment organ sound, and followed the patients for their own loss of the organcaused by psychological and social factors affect the confidence of the patient’s ownvoice, in addition to the gag reflex from the nose catheterization tube intolerancecause the patient to apply a wide range of its future needs to further study andimprovement.
