Abstract

The invention relates to medicine, namely to surgical dentistry. The aim of the invention is to increase the fixation strength. The goal is achieved by additionally forming an intraosseous canal in the branch of the jaw below the fracture plane, while the blunt end of the spoke after bending is fixed along the lower edge of the jaw in the bone chute formed in the compact layer of the lower edge of the jaw. A positive effect is evaluated by an improvement in functional results.

Description

The invention relates to medicine, namely to surgical dentistry.

The aim of the invention is to increase the fixation strength.

The method is carried out as follows

Under general or local anesthesia, soft tissues are dissected in the region of the mandible angle. Expose the outer surface of the angle and the branches of the lower jaw closer to its posterior edge. Match the fragments in the correct position. Boron form the intraosseous canal with a length of 1 cm in the direction from the lower edge of the jaw to the condylar process. Boron, on the other hand, forms a bone chute within the outer compact and spongy layers, while the bone chute is a continuation of the intraosseous canal. At a distance of 5-7 mm from the plane of the fracture, an additional intraosseous canal is formed by the sharp end of the needles or a special long boron, which extends to the plane of the fracture. Form intraosseous channel in

1.5 cm in the condylar process. The Kirschner needle is inserted sequentially through the intraosseous canal in the region of the lower edge of the jaw, through the bone chute, through the intraosseous canal below the fracture plane, then through the fracture plane into the intraosseous canal of the condylar process. The lower end of the spokes is bent at an angle and placed along the lower edge of the jaw in the bone chute running in the direction anterior to the exit point of the spoke in the region of the lower edge of the jaw. Carefully suture the periosteum, try to put stitches directly under the horizontal portion of the spokes in the region of the lower edge of the jaw. Soft tissues are sutured. The wound is drained for 1 day with rubber bands. Post-maxillary fixation in the postoperative period is not required. From the second day after the operation, the patient is allowed to open his mouth for food, from the fifth to the sixth day he is chewed at first soft and then regular food. The ability to work is restored on the 14th-17th day after the operation.

Example: Patient M., born in 1968, was admitted for a closed fracture of the left condylar process of the mandible with a significant displacement of fragments. It was not possible to eliminate the displacement and restore the bite by orthopedic measures. The decision was made about surgical treatment. Osteosynthesis of the jaw was performed using a Kirchner needle according to a conventional method, which is the essence of the proposed method. Under endotracheal anesthesia with mouth intubation, soft tissues were cut along the lower edge of the jaw. The periosteum was peeled off along the outer surface of the branch and the angle of the jaw closer to the posterior edge of the branch. The fracture site was determined. Through the surface of the fracture, an intraosseous canal is formed in the condylar process 1.5 cm long, Boron forms an intraosseous canal in the region of the lower edge of the jaw 1 cm long, and then, as a continuation of the canal, there is a bone trench within the outer compact and spongy layers in the direction to condylar process. In the area of the branch located immediately below the plane of the fracture, an intraosseous canal with a length of 7 mm is formed. Fragments are precisely matched. The Kirschner needle is successively drawn through the intraosseous canal in the region of the lower edge of the jaw, through the bone chute along the outer surface of the jaw branch, through the intraosseous canal below the fracture plane, through the fracture plane and further into the inner

The bone canal in the condylar process to a depth of 1.5 cm. The lower end of the spokes is cut, and the remaining 1.5 cm long part is curved anteriorly and laid in the bone chute formed in the compact layer of the lower edge of the jaw. The wound is sutured in layers, while the periosteum is sutured with two catgut sutures directly below the horizontal portion of the spokes in the region of the lower edge of the jaw. The wound is drained with a rubber band for 1 day. Since that day, the chewing of soft foods is allowed. On the 14th day, the patient was discharged and set to work.

Claims (1)

The proposed method provides the strength of fixation of fragments, prevents postoperative complications in the form of fragment displacement, reduces the time of treatment of patients from 35 (using traditional methods) and from 25 (using known methods) to 17-20 days. The invention of the method of treating a mandibular condylar fracture by fixing fragments with a Kirschner spoke inserted through the fracture plane into the intraosseous canal in the region of the lower edge of the jaw, characterized in that, in order to increase fixation strength, an intraosseous canal is additionally formed in the jaw branch below the fracture plane, however, the blunt end of the spokes after bending is fixed on the lower edge of the jaw in the bone chute formed in a compact layer of the lower edge of the jaw.
