Selective Cervical Denervation for Cervical Dystonia: Modification of the Bertrand Procedure.

BACKGROUND

Cervical dystonia, commonly referred to as spasmodic torticollis, is a neurological disorder characterized by aberrant, involuntary contraction of the muscles of the neck and shoulders. One surgical option that can be considered is selective cervical denervation.

OBJECTIVE

To report our modification of the Bertrand procedure for selective cervical denervation.

METHODS

Our modification of the Bertrand procedure for selective cervical denervation is reported with intraoperative photographs and schematic depictions of the operative steps.

RESULTS

We report our modification of the Bertrand procedure for selective cervical denervation, which consists of a combination of C2-6 denervation, myectomy of the splenius capitis and/or semispinalis capitis, myotomy of the levator scapulae when indicated, and myotomy and selection denervation of the sternocleidomastoid. The combination of techniques utilized depends on the subtype and severity of cervical dystonia.

CONCLUSION

Our modification of the original Bertrand procedure for selective cervical denervation represents an alternative surgical strategy for the treatment of cervical dystonia, with the potential advantages and disadvantages discussed.
