arytenoidectomy or arytenoidopexy

Dissection of the diseased sacral cartilage, or fixation of unstable sacral cartilage, is one of the surgical methods for the treatment of vocal cord paralysis. Treatment of diseases: vocal cord polyps congenital vocal dysplasia Indication The bilateral vocal cords are abductive paralysis, the breathing is not smooth, and the tracheal tube can not be pulled. Contraindications Those with cervical disease do not need this method. Preoperative preparation 1. Neck radiographs except for glottic or tracheal stenosis. The patient's cervical spine is normal and can be used as a hanging laryngoscopy. 2. Fiber laryngoscopy to check the activity of the vocal cords, confirmed to be abductive paralysis, no scar adhesion in the intercondylar area. Surgical procedure 1. Introduce a suspended direct laryngoscope to expose the glottis and focus on the focal length of the laryngoscope. 2. Detect the activity of the vocal cords with a laryngeal probe or a laryngeal suction tube. 3. Incision at the mucosa of the epiphyseal fold, expose the sacral cartilage, cut off the surrounding submucosal tissue, free the sacral cartilage, and narrow the cartilage with a laryngeal forceps to remove it. 4. Use a laryngeal electrocautery to electrocauterize in the pocket of the cartilage after removal of the sacral cartilage for hemostasis and closed surgery. 5. The vocal cords can be displaced to the outside due to the contraction of the scar after electrocautery. 6. Exit the hanging laryngoscope.
