A virtual simulation system with haptic display for laryngoscopic vocal cords surgery was developed.

This paper makes an analysis and a discussion around the breath application,vocal cords and throat,the resonating application,the distinct and clear pronunciation,the mood to control,etc.

The function of the vocal cords is the foundation of singing,but the beam of voice-the two regulative function produced by the vocal cords and the tune of resonance has very important function in the mixed true voice and falsetto and in the throats voice.

Preliminary clinical study of dexamethasone on prevention relapse of polyp and nodules of vocal cord in microlaryngoscopic surgery under suspension laryngoscope;

Clinical observation on microwave therapy for treatment of 25 patients with vocal cord leukoplakia under fiberoptic laryngoscope;

Comparative study of heat injury on vocal cord mucosa induced by different power semi conductor laser;

The result shows that by using this method,the vibrational characteristic of vocal folds can be recognized more completely,and the diseases in vocal folds can be diagnosed quantitatively.

Vocal fold abduction for bilateral vocal cord paralysis through the suspension laryngoscopy;

Glottic measurement in dyspnea degree Ⅰand Ⅱ caused by adult bilateral vocal cord paralysis;

Substance P on reinervating vocal cord paralysis by neuromuscular pedicle transplantation;

The effect evaluation of microwave therapy for vocal cord polyp with laryngofiberscope and prop-up laryngoscope;

The effect of microwave therapy for vocal cord polyp in different way;

Methods Vocal cord polypectomy through Micro-Stryker Instruments combined with cystoscope and self-retaining laryngoscope were performed on 96 patients.
