Abstract |
Objective: The anterior cervical microforaminotomy technique has been developed to enhance the treatment of cervical spondylotic radiculopathy secondary to uncovertebral osteophytes. These novel surgical approaches may be advantageous because they allow direct decompression of the nerve root while preserving normal movement and stability of the motion segment. But, the use of this technique is limited for the treatment of large migrated cervical disc herniation that is generally treated by conventional approach through an anterior diskectomy followed by bone-graft reconstruction. The authors has applied 'extended anterior cervical microforaminotomy' for these lesions on minimally invasive basis.
Methods: For these lesions, the anterior foraminotomy is made like a flask-shaped hole, with a smaller outer opening similar to that for the anterior cervical microforaminotomy but incorporating a larger inner opening to accommodate the extent of the large migrated disc in a longitudinal and transverse dimension; however, it does not require bone fusion or postoperative immobilization. The surgical technique is described with two illustrated patients. The authors present the early outcome data obtained in 9 patients who underwent the extended anterior cervical microforaminotomy.
Results: The outcome was excellent in 7 patients (78%) and good in 2 patients(22%) based on Odom's criteria. None of the patients were symptomatically or neurologically worse. Spinal stability was well maintained postoperatively.
Conclusion: This extended anterior cervical microforaminotomy technique has shown excellent clinical outcomes with fast recovery and adequate anatomical decompression in patients with migrated cervical disc herniation. |
