Abstract
Dumbbellshaped thoracic tumors represent a distinct type of tumor and involve in both the spinal canal and the posterior thoracic cavity Successful treatment for the tumors depends on gross total resection GTR via an open laminectomy and facetectomy or transthoracic transpleural approach In this case series we report our experiments with minimally invasive method for the removal of extradural dumbbell thoracic tumor and present related literature reviewWe retrospectively reviewed two patients with dumbbellshaped thoracic tumors who underwent minimally invasive resection and unilateral transforaminal thoracic intervertebral fusion TTIF through unilateral paraspinal muscle approachwith a spotlight expandable tubular retractor Clinical data tumor characteristics and outcomes were analyzedTwo patients underwent successful minimally invasive treatment of their spinal neoplasms There were no procedurerelated complications The efficacy in terms of neurological recovery pain improvement and operative variables length of incision operative duration blood loss and hospital stay was better when compared with prior published studies Postoperative CT image demonstrated complete resection of dumbbell tumor in the patients The solid fusion was obtained after 3 months followup and there was no failure of internal fixationIf the medial border of intracanal component of extradural dumbbell tumor is near the midline of canal and the pedicles of adjacent vertebrae to tumor are intact minimally invasive resection of tumor through unilateral paraspinal muscle approach combined with unilateral TTIF is good choice
