Subjective And Objective Evalution For Vocal Cord Benign Lesion With Medial Microflap Technique

0bjective To analyze the clinical value of medial microflap technique underself-retaining laryngoscope in the treatment of vocal cord benign lesion．Methods From August2010to August2011，40patients with vocal cord diseases，including34patients with vocal cord polyps and6cases with vocal cord cyst，receivedminimally invasive surgery in our hospital by using medial microflap technique underself-retaining laryngoscopy．Before and after the surgery,all the patients were undergonestrobolaryngoscope,acoustic analysis and self-assessment.In addition,20normal subjectswere also analyzed as the controls.Results Four weeks after the surgery,strobolaryngoscope examination showed thatall patients’s vocal cords moved，opened and closed fine，the mucous membrane weresmooth. All the parameters were different significantly between preoperation and fourweeks postoperatively (P<0.01).The difference between four weeks postoperatively andthe control group was statistically insignificant(P>0.05).The acoustic parameters were notclosely related to the VHI score.Conclusion1. In the treatment of vocal cord benign lesion,such as vocal cord polyps and vocalcord cyst,medial microflap technique turned out to be secure,accurate and minimallyinvasive,operative outcomes was satisfactory, accord with the development trend ofminimally invasive and function surgery.2. Strobolaryngoscope examination and voice acoustic analysis can evaluate theoperative effect objectively and quantitatively. Conversely,voice handicap index(VHI) canevaluate the degrees of the disorders subjectively. One can not speculate the VHI score by the voice acoustic analysis.Consistency of three methods can do a comprehensiveassessment for the Operative effect.
