| 成果简介 | NOVELTY - Invention refers to medicine, namely to oncology and surgery. Method of glossectomy at the surgical stage of treating cancer of the movable part of the tongue involves removal of the anatomical structures adjacent to the movable part of the tongue and the oral floor tissue. First, the patient’s oral cavity is exposed under endotracheal anaesthesia with the use of a surgical mouth gag. Then, a traction suture is applied in the area of the tongue tip at distance of 1.5-2 cm from the line of the intended incision and lateral to the tip of the tongue; the ends of the traction suture are clamped by a mosquito forceps. Further, resection lines are marked on the tongue. Monopolar electric scalpel is used to make a first incision from the centre of the oral floor with a transition to the mucous membrane of the maxillary lingual groove to a projection of the posterior edge of the maxillary hyoid muscle. Styloid muscle is then approached and transected with a monopolar electrosurgical unit. Further, a traction interrupted suture is applied on the edge of the transected styloid muscle; the ends of the sutures of which are brought out of the oral cavity and fixed with a clamp. Further, an incision is made along the mucous membrane of the maxillary lingual groove and the floor of the oral cavity to the level of the mouth of the submandibular duct, visualizing the sublingual salivary gland. Thereafter, a pole of the ipsilateral sublingual salivary gland is prepared to visualize the anterior edge of the hyoid-lingual muscle. Then the hyoid-lingual muscle is transected with a monopolar electric scalpel, the lingual artery is visualized and ligatured distally in the maxillary-hyoid muscle. Further, the upper bundles of the chin-hyoid muscle are transected with a monopolar electric scalpel, and a median lingual septum, which is a deep resection border, is approached. Thereafter, a visually controlled medial incision is made along the lateral surface and back of the tongue through the lingual muscles. Then the anterior resection edge is formed by a longitudinal incision, which is started between the tip and the traction suture applied at the beginning of the intervention, continued in the lingual septum layer and combined with the medial edge of the transverse resection at angle of 90° at the level of the lingual septum, from which the affected part of the tongue, the sublingual salivary gland and the cellular tissue of the bottom of the oral cavity are separated. Thereafter, the edges of the defect in the area of the bottom of the oral cavity, the maxillofacial groove and the movable part of the tongue are mobilized by preparing the blunt and sharp paths, bringing them together and fixing them with interrupted sutures. In the distal section of the wound, the edges of the defect are not tightly sutured together in order to preserve the function and ensure drainage of the postoperative wound. USE - Medicine. ADVANTAGE - Method enables performing a glossectomy as a surgical stage of treating cancer of the movable part of the tongue, reducing the rate of loco-regional recurrences of tongue cancer. 3 cl, 3 ex |
