Exoscopic-assisted posterior approach for the removal of thoracic dumbbell schwannoma: Three-dimensional operative video.

ABSTRACT: "Dumbbell" tumors are described as benign neoplasms presenting both intraspinal and extraspinal extensions, connected through the intervertebral foramen (McCormick, 1996) [1]. About 90 % of such tumors are histologically classified as schwannomas that most frequently arise in the thoracic region (Takamura and et al., 1997) [2]. Diagnosis is usually achieved as soon as the dimensional increase of the intracanal portion results in nerve or spinal cord compression (Ishikawa and et al., 2002) [3]. How to obtain a complete surgical resection of tumors with large or ventrally located extraforaminal components with a minimally invasive approach is still debated (Payer and et al., 2006) [4]. The single-stage posterior removal of the tumor is the most performed approach for lesions presenting with
