OBJECT: A new dorsolateral decompressive procedure involving a unilateral approach has been devised for the treatment of cervical @entity1745 . In this operation, the posterior spinal elements of the contralateral side are not disturbed, and thus, @entity86 of the cervical spine can be avoided. Following decompressive surgery via the unilateral approach, the cervical spine was kept more stable compared with the results obtained after wide laminectomy or other expansive laminoplasty procedures. METHODS: Twenty-six @entity1 underwent dorsolateral decompressive surgery, and the @entity1 ' clinical and radiological results were examined during the follow-up period to evaluate neurological function and @entity86 of the cervical spine. The underlying conditions for @entity602 were @entity4720 (19 @entity1 ), @entity3057 (three @entity1 ), and ossification of yellow ligament (four @entity1 ). The follow-up period ranged from 6 to 110 months (average 35.5 months). Functional recovery, which was rated by using the Japanese Orthopaedic Association scoring system, was an average of 56% in all @entity1 (100% being equal to full recovery). The recovery rate was compatible with those attained after other expansive laminoplasty procedures. Radiographically, progression to swan-neck or @entity85 was not observed in any @entity1 . No postoperative spinal instability was noted. Based on computerized tomography myelograph evaluation, the average transectional area of the dural tube at the C4-5 level was expanded from 122 mm2 to 169 mm2, and the transectional area of the spinal cord at the C4-5 level was expanded from 39.6 mm2 to 52.9 mm2 after surgery. CONCLUSIONS: The authors conclude that this operative procedure could be used as a new option for the treatment of cervical @entity1745 .
