Microsurgical dennervation in treatment of focal cervical muscular dystonia: analysis of treatment of 26 patients with laterocollis
26 patients with laterocollis were enrolled into the study. All enrolled patients underwent 60 microsurgical denervations of dystonic muscles, including 26 (43,33%) selective dennervations of ipsilateral sternocleidomastoid muscle, 24 (40%) selective posterior ramisectomy of C1-C6 rootlets (Bertrand's procedure), 10 (16,67%) denervations and myotomias of dystonic muscles of omo-trapezoid triangle (DMOTT). The outcome evaluation was conducted via neurological examination and Toronto Western Spasmodic Torticollis Rating Scale questionnaire. The outcomes showed 3-times decrease of severe laterocollis (up to 0%), the average severity of spastic torticollis with laterocollis prevailed among all patients (62,5%), in 37.5% we observed spastic torticollis with mild. Indicators of severe disability decreased from 15,38% to 0%, light level increased from 11,54% to 46,71%. Implementation of denervation and muscle myotomes shoulder-blade triangle allowed to significantly affect the performance of spastic torticollis severity of laterocollis.
