cricoid hyoid fixation

Ring cartilage hysterectomy (cricohyoicopexy), cartilage cartilage cartilage hysterectomy (cricohyoidoepiglottopexy) is a functional laryngectomy. The purpose is to remove the laryngeal tumor and maintain the breathing and swallowing function of the throat without wearing a tracheal cannula. The condition of the operation is to retain the annular cartilage to maintain sufficient respiratory passage, to retain one side of the cartilage, to remove or retain the epiglottic cartilage, to fix the suture with the hyoid bone, to free and relax the cervical trachea, so as to approach the base of the tongue, in order to Keep swallowing. Treatment of diseases: laryngeal cancer Indication 1. Glottic laryngeal cancer has invaded the former commissure. 2. Throat room cancer is violated under the silent door. 3. The roots of the epiglottis and the ventricular cancer have invaded one side of the sacral cartilage and the vocal cords are fixed. Contraindications The age of the body is weak, the vital organs such as the heart and lungs are poor, and the surgery does not restore hope. Preoperative preparation 1. Neck radiograph or CT examination. 2. Fiber laryngoscopy to see if there is any invasion under the glottis. Surgical procedure (a) annular cartilage hyoid bone fixation 1. Incision, separation of the anterior cervical muscle layer, cutting off the thyroid isthmus, low tracheotomy and laryngectomy. 2. Cut the upper edge of the annular cartilage, cut the ring muscle, and free the inner perichondrium to leave enough safety margin. 3. Free thyroid cartilage, cut off the thyroid gland muscle and pharyngeal muscle. 4. Free the hyoid bone, cut off the muscles under the hyoid bone, and separate the periosteum. 5. Separate the epiglottic anterior space, pull out the epiglottis, remove the diseased side cartilage from the epidural fold, and perform subtotal laryngectomy for the resected ventricular band, vocal cord, throat, and epiglottis. Keep the cartilage. 6. Free and relax the cervical trachea, suture the cartilage and suture the hyoid bone. 7. Suture the muscle layer and skin. (B) ring cartilage epiglottic cartilage hyoid bone fixation 1. Incision, separation of the anterior cervical muscle layer, cutting off the thyroid isthmus, low tracheotomy and laryngectomy. 2. Cut the upper edge of the annular cartilage, cut the ring muscle, free thyroid cartilage, cut the thyroid gland and the pharyngeal muscle and the ring cartilage. 3. Incision in the upper edge of the thyroid cartilage, subtotal laryngectomy under the root of the epiglottis including the ventricular zone, vocal cords, larynx, and one side of the cartilage. Preserve the first 3/4 of the cartilage and epiglottic cartilage. 4. Relax the cervical trachea and suture the cartilage with the hyoid bone and the epiglottis. 5. Suture the muscle layer and skin. complication lung infection.
