METHOD FOR LARYNX RESECTION WITH PRESERVATION OF CARTELISTIC FRAME IN T1-T3 MALIGNANT TUMORS Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: a tracheostomy is applied. Then a vertical skin incision is made along the midline of the neck from the level of the hyoid bone to the upper tracheal rings. The larynx is exposed and the soft tissues of the neck are removed from the affected and partially healthy side of the larynx. The internal perichondrium is separated from the thyroid cartilage on the healthy and diseased side with the formation of two tunnels. The incision is deepened to the thyroid cartilage. The outer layer of the perichondrium is peeled off with a raspator and a conicotomy is performed with a transverse incision along the upper edge of the cricoid cartilage. Next, the perichondrium of the thyroid cartilage is incised along its lower edge and, without dissecting the thyroid cartilage, the inner leaf of the perichondrium is exfoliated along the midline with scissors, with mobilization of the anterior commissure, retreating to the sides by 1 cm. Then the thyroid cartilage is dissected with a disc saw, retreating from the midline by 1 cm to the healthy side. The larynx is opened, the extent of the tumor lesion is determined, and the remaining inner layer of the perichondrium is detached on the side of the lesion. The tumor is excised with an electric knife within healthy tissues with the obligatory inclusion of the anterior commissure. The resulting defect is covered with mobilized local tissues. Further, the laryngeal cavity is tightly tamponed with a turunda with xeroform and antibiotics, the end of the turunda is taken out through the tracheostomy. After that, the plates of the thyroid cartilage, together with the outer leaf of the perichondrium, are sutured with 2-3 sutures, comparing the edges of its incision. The wound is sutured tightly in layers.

EFFECT: method allows preserving the larynx frame and the thyroid cartilage plate on both sides, restoring the respiratory and dividing functions of the larynx in the immediate postoperative period, significantly reducing the number of postoperative complications.
