In the general opinion, most people think that it is very simple to do a polyp of the vocal cord, and it can be done in a few minutes at the outpatient clinic. This view is actually quite outdated at present, because with the development of laryngeal microsurgery, the application of minimally invasive surgery to treat benign laryngeal lesions has become a definite clinical technology trend. Minimally invasive laryngeal surgery refers to the application of a supported laryngoscope under general anesthesia to expose the surgical area, use a microscope to magnify the lesion, and use a laser to remove the lesion. This surgery is very effective because it exposes the lesion clearly, magnifies the very small lesion to a very clear level, and uses a laser to cut it precisely, so there is no side damage to the vocal cords and the voice recovers better after surgery. Traditional surgery is performed under an indirect laryngoscope, so the doctor can’t see the lesion clearly with the naked eye, and the laryngeal forceps are used to remove the lesion, which is relatively rough, so it is easy to have problems such as vocal fold damage or lesion residue, and the postoperative sound quality is not high, especially for those vocal fold polyps and vocal fold nodules with a wide base. Therefore, minimally invasive surgery, with its advantages of precise cutting, no bleeding and good postoperative results, has gradually become the procedure of choice for the treatment of benign laryngeal lesions, although it is relatively expensive compared to traditional surgery, and it is worthwhile for clinicians to vigorously promote it so that patients can benefit from it for life.
