vocal cord tightening

Vocal cord tensioning is also called surgical to elevate vocal pirch or ring nail approach. This procedure is to shorten or tighten the ring gap to extend the anteroposterior diameter of the larynx. Tighten the vocal cords to increase the tension of the vocal cords and enhance the tone. In the past 20 years, with the improvement of the physiological and pathological knowledge of the vocal function of the larynx, as well as the development of diagnosis and treatment techniques for vocal diseases, such as dynamic laryngoscopy, laryngeal microsurgery, laser surgery, etc., the laryngeal surgery has been achieved. It can not only remove the lesion, but also preserve or improve the function of the voice. Therefore, the vocal surgery developed on the basis of laryngology to improve the voice has been widely promoted worldwide. Von Leden et al. (1989) pointed out that snoring surgery is the "aesthetic surgery of the voice system for improving the voice". It is the surgical function to restore or reconstruct the vocal function of the throat, so that the voice is clear, loud and pleasing. , has rhythm, and meets the purpose of its age and gender characteristics. The main surgical techniques included in the voice surgery include: 1 vocal cord benign lesion removal; 2 unilateral vocal cord paralysis midline internal thrust, tonal abnormal surgery; 3 recurrent laryngeal nerve paralysis nerve graft or neuromuscular pedicle graft; 4 larynx Tumor resection and partial reconstruction. Treating diseases: vocal cord polyps Indication Mainly used to treat women with low tone or ring muscle dysfunction. Preoperative manual examination is very important. The method is to use both hands to make the cartilage and thyroid cartilage close to each other and observe the improvement of vocalization. The specific operation is that the right hand finger pushes the lower edge of the annular cartilage upward, while the left hand shows the fingertip to push the thyroid cartilage notch down. If the tone is obviously elevated and the patient is satisfied, surgery can be considered. Surgical procedure Under local anesthesia, the level of the flat ring is made into the anterior cervical transverse incision, the skin and subcutaneous tissue are cut, bluntly separated, and the anterior lower edge of the thyroid cartilage, the ring of the thyroid cartilage and the leading edge of the annular cartilage are fully exposed. A needle was sutured from the anterior arch of the cartilage and the anterior inferior border of the thyroid cartilage with a thick line of 10, and the suture was passed through the anterior membrane of the ring, and the left and right sutures were simultaneously ligated. During the operation, the patient should be squeaked while tightening the suture, and the tension is based on the patient's best vocalization or slightly higher. After ligation, the layers of tissue were sequentially sutured. After the operation, the ban was rested for 1 week.
