CO₂Laser And Power System For Laryngeal Keratectomy For Resection Of Vocal Cord Polyps Curative Effect Contrast

Communication is the important tool and essential elements of the humansocial development and progress，and language is the way of communicationwhich the most direct, the most vivid, the most easy to accept，communicationstandard related to the quality of life closely, especially for the acoustic crowdsuch as teachers, the broadcast management, actors and so on，who have morestrict requirements of the quality of their voice，and the health voice is the mostbasic security of their career。With the development of the society, human’sactivity becomes more frequent and more colorful，if one has a beautiful、healthy and pleasant voice that can improve his confidence and will be betterexpression and express their emotions, and more effective to achieve the urposeof good communication, establish a good interpersonal relationship，So healthproblems will undoubtedly become another hot topic which the modern voiceof the social concerned，more and more people will be to the hospital for thevoice problems，Vocal cord polyp is a common vocal benign lesions that causeof voice disorders，with the conservative treatment for patients but no relief，they need surgery.With the development of science and technology, and gavebirth to a lot of surgical therapy。Scholars at home and abroad have done a lotof clinical research in order to look for a more effective and more advantage ofsurgical methods。in our country, there is no research about the comparison ofCO₂laser surgery the new surgical echniques and the dynamic system of throatcut the suction the mature surgical technique。Based on the above research background。The purpose of this study is to observe the postoperative curative effect of the treatment of vocal polyps byCO₂laser and power system for laryngeal keratectomy。Methods: collected87cases of patients with vocal polyps from July2011to February2012in ourdepartment，randomized, laser group:16cases, the power system groups:71cases, and normal group in20patients, were used to CO₂lase the newintroduce technich and power systems suck cut system，ATMOS dynamiclaryngoscope voice and acoustic analysis software as the target to observe thecurative effect。Results: compared with the preoperative dynamic laryngoscopeshows: the mucosal surface is smooth, vocal vocal edge tidy, pronunciation isgood subglottic closed, but the author also pay attention to two groups of casesexist a certain proportion of patients who underwent the dynamic laryngoscopeedge smooth surface vocal cords, but who do voice, the reason not very clear。The different stage voice acoustic index comparison results show that:1, scoresof normal and compared: F0no significant difference （P>0.05）, Jitter andShimmer are higher than the normal group （P <0.01）; the preoperative andpostoperative scores than4weeks F0Jitter, Shimmer, there were no significantdifference （P>0.05）, after two weeks of all the indexes have significantdifference （F0: P <O.O5; Jitter and Shimmer: P <0.01）, after two weeks,4ZhouJiPin perturbation and the amplitude perturbation are a preoperativedeclined, postoperative4weeks down is obvious。Three, two group of eachstage and normal group compared with: F0no significant difference （P>0.05）,Jitter have significant difference （P <0.01）, which is a little high, but thenormal group whole numerical are in decline by stage, the power system of alaser group decline, CO₂laser after two weeks Shimmer of the normal grouphave significant difference （P <O.O1）, the power system group havedifference （P <0.05）,4weeks after two groups the normal group and Shimmerthere were no significant difference （P>0.05）。Conclusion:1, CO₂laser andpower system for laryngeal keratectomy both of the two surgery methods are both effective treatment，the patients’ quality of pronunciation were improvedobviously, the outlook is similar.2、After two weeks and four weeks thepower system throat cutting group is advantage of voice acoustic index， that ismeans the whole recovery of the vocal polyps by the power system throat isquicker than CO₂laser group3、preoperative and postoperative reasonablevoice training, good state of mind and establish a reasonable expectation tovoice recovery is very important。...
