supraorbital nerve avulsion

The avulsion of the trigeminal nerve includes three branches of the supraorbital nerve, the infraorbital nerve and the inferior alveolar nerve. Since the infraorbital and inferior alveolar neurotomy is not superior to ethanol injection and is performed by a maxillofacial surgeon, only supraorbital nerve ablation and avulsion are introduced. Treating diseases: trigeminal neuralgia Indication Supraorbital nerve avulsion is suitable for pain limited to the extent of the upper branch of the trigeminal nerve, and there is still severe pain after ethanol injection or other medication. Contraindications Those who involve multiple or other branches are not suitable for this operation. Preoperative preparation No special preparation is required except for shaving the eyebrows before surgery. Surgical procedure 1. Incision Make a transverse incision in the inner half of the eyebrow. 2. Exposing the upper and upper organs of the pulley After cutting the skin, the periosteum is directly accessed, and the periosteum is separated upwards and downwards to find the supraorbital sac and the supraorbital nerve that it emits. The inner side is the upper nerve of the trochlear. 3, avulsion nerve After separating the supraorbital nerve, the nerve was cut off, and the distal and proximal ends were clamped with a vascular clamp, and the vascular clamp was rotated. The proximal end was ablated a few centimeters, and the distal end was aspirated from the skin as much as possible to achieve the purpose of prolonging the curative effect. It is also possible to cut off and avulse the upper nerve of the pulley at the same time, and the effect may be better. complication Some viral neuralgia, postoperative pain may be eliminated.
