Kirschner wire/Studian wire craniopexy

Kirschner wire/Schoor's needle craniomaxillary fixation for the treatment of maxillary fractures. There are two types of bone traction needles: 1 Kirschner needle, which is a thin steel needle with a diameter of 1.5mm, a length of 30cm, or 27.5cm, and a triangular tip at one end for drilling into the bone and through the bone. After that, it can be pulled by tightening it with a tight hook. 2 Steinmann Pin, a thick steel needle that can be pulled after being penetrated into the bone. It has two diameters, 3.7 mm thick, 3 mm thin, and triangular at the tip. There are a variety of lengths, ranging from 12.5 to 25 cm, every 2.5 cm. Treatment of diseases: jaw fractures Indication Kirschner wire/Schoor's needle craniomaxillary fixation is only recommended for complex facial fractures, such as multiple facial fractures, including multiple DeFortI and III fractures, sputum smashing, fundus hemorrhage, and conservative treatment. Closed reset, suspended externally fixed. Surgical procedure 1. The amount of quilting wire was fixed in the internal fixation, the maxillary anterior teeth were extremely loose and removed, the mandibular molars were missing, and the maxillary and anterior molars were ligated between the jaws. 2. Above the plane of the vestibular sulcus, insert a Sterling needle from both sides through the cheek, drill into the maxillary alveolar process on each side, and intersect the nasal spine. The Sterling needle protrudes about 3cm from the cheek skin. . 3. Squirt the outer cheeks of the cheeks on both sides, and fasten them to the outer fixing bracket of the head device with the joints and connecting rods. complication The first step is the emergency treatment of severe high-level maxillary fractures. Take decisive measures such as the Sterling needle through the upper jaw to suspend the upper segment and compress it to the base of the skull to resolve the craniofacial separation, to achieve hemostasis and prevent secondary infection, traumatic cerebrospinal fluid leakage. Sodium sulfamethazine should be used to prevent infection, and the occlusal relationship of the remaining healthy teeth will be relegated to a secondary position. Even if the wrong jaw occurs, the chewing problem can be solved by adjusting the jaw and the teeth.
