SU1503776A1 - Method of treatment of microgenia with adapted occlusion - Google Patents

Abstract

The invention relates to medicine, namely to oral and maxillofacial surgery in the treatment of microgenia. In order to achieve a cosmetic effect while improving the nutrition of the graft, an osteotomy is performed in the horizontal plane of the chin mandible and additionally an osteotomy between the cortical plates of the lower jaw body below the tooth roots with the formation of a shaped non-free graft, is displaced anteriorly and fixed.

Description

This invention relates to medicine, namely to surgery in the maxillofacial region.

The purpose of the invention is to achieve a cosmetic effect while improving the nutrition of the graft.

The method is carried out as follows.

On the mucous membrane of the lower lip, a incision is made up to 4 cm in length, 1.5–2 cm above the lower fortification of the mouth to the bone. The anterior surface of the chin and the edge of the jaw are skeletised to the level of the projection of the third mole on each side. Parallel to the edge of the lower jaw and indent from it upward by 8-10 mm, a cross-section of the bone is made from 5P to HZ. From the edges of the cut, the osteotomy lines on each side descend vertically down to the edge of the lower jaw, capturing the outer cortical plate, and then along the lower edge to the level of 2-3 mol, where it goes to the inner cortical plate and goes up to 8-10 mm. Then, using an osteotome, a flat osteotomy is performed on both sides of the anterior chin. The osteotome is placed into a cut on the lower edge of the jaw and directed toward the inner cortical plate at an acute angle. The formed bone fragment is extended to the required distance by sliding along the plane of the split jaw, and then fixed with polyamide sutures.

Example. Patient P., 18 years old, with a symmetric microgenia with an adapted bite, was operated on by an incision on the mucous membrane of the lower lip 4 cm long above the lower fortification of the mouth to the bone. The anterior surface of the chin and the edge of the lower jaw are skeletal and to the level of the projection of the third mole on each side. Parallel to the edge of the lower jaw and indent from it upward by 8-10 mm, a through section of the bone was made from 31 to HZ. Further, the osteotomy line is continued vertically down to the outer cortical plate and lower jaw edge to 2-3 mol, and then to the inner surface of the cortical plate and upwards by 8-10 mm. Make

Plane osteotomy on both sides of the leading edge of the chin. Next, the osteotome from the cut on the lower edge of the jaw is directed toward the inner cortical plate at an acute angle. A bone fragment is formed, which is extended to the front by sliding along the splitting plane and fixed with polyamide suture. The wound is sutured in layers paglu.ho. The operation and the postoperative period were uneventful. The patient was discharged from the hospital 13 days after surgery. When monitoring signs of relapse was not.
