Subjective and objective evalution for vocal cord benign lesion with medial microflap technique

OBJECTIVE To analyze the clinical value of medial microflap technique in phonosurgery under suspension laryngoscope for the treatment of benign vocal cord lesions.METHODS Minimally invasive surgery was performed in 40 patients with benign vocal cord lesions.The medial microflap technique was used during suspension laryngoscope.There were 34 patients with vocal cord polyps and 6 cases with vocal cord cyst.Strobolaryngoscopy,subjective and objective voice analysis were conducted in all the patients before and after operation.In addition,20 normal subjects were also analyzed as control group.RESULTS Four weeks after operation,strobolaryngoscopy showed that the vocal cords of all the patients moved,opened and closed well,and the mucous membrane were smooth.All of the parameters were significantly different before and four weeks after operation(P 0.05).There were no relationship between the acoustic analysis parameters and Voice Handicap Index(V H I).CONCLUSION Medial microflap technique is a safe,accurate and minimally invasive method for the treatment of benign vocal cord lesion such as vocal cord polyps and vocal cord cyst.The operative outcomes are satisfied and the technique meets the development trend of minimally invasive and functional surgery.Strobolaryngoscopy,acoustic voice analysis and VHI can assess the operative efficacy comprehensively.
