Résumé
Dumbbell schwannomas of the thoracic spine are challenging to cure surgically. Surgeons are familiar with posterolateral approaches to the spine, however, these may provide inadequate exposure for large tumors extending to ventral extraspinal compartments. Ventrolateral transpleural approaches offer direct access to the ventral thoracic spine and intrathoracic cavity, though are associated with increased morbidity and pulmonary complications, and may necessitate a staged procedure in order to address concomitant dorsal pathology. Herein we describe our experience with single-stage, posterior approach to dumbbell schwannomas with large ventral extraspinal components, and review the literature regarding surgical approaches for these tumors. Retrospective review of patients who underwent a single-stage, posterior spinal surgery for thoracic dumbbell schwannomas from 2008 to 2018. Inclusion criteria were age > 18 years and ventral thoracic tumor component. Three patients underwent a simultaneous retropleural thoracotomy and posterior spinal approach, through a single incision, for the resection of dumbbell (intradural and extradural) schwannomas. Mean age was 49.7 years and 2 patients were female. All patients were neurologically intact at baseline. Lesions were 4-8.2 cm in the largest dimension (mean 6.1 cm). GTR was achieved in all patients. One pleural rent occurred intraoperatively; there were no other intraoperative or perioperative complications. At a mean follow-up of 14.1 months all patients remained motor and sensory intact and there was no evidence of recurrence. The combined retropleural thoracotomy-posterior spinal approach provides safe and sufficient access for resection of large dumbbell schwannomas of the thoracic spine.

BACKGROUND
BACKGROUND
Dumbbell schwannomas of the thoracic spine are challenging to cure surgically. Surgeons are familiar with posterolateral approaches to the spine, however, these may provide inadequate exposure for large tumors extending to ventral extraspinal compartments. Ventrolateral transpleural approaches offer direct access to the ventral thoracic spine and intrathoracic cavity, though are associated with increased morbidity and pulmonary complications, and may necessitate a staged procedure in order to address concomitant dorsal pathology. Herein we describe our experience with single-stage, posterior approach to dumbbell schwannomas with large ventral extraspinal components, and review the literature regarding surgical approaches for these tumors.
METHODS
METHODS
Retrospective review of patients who underwent a single-stage, posterior spinal surgery for thoracic dumbbell schwannomas from 2008 to 2018. Inclusion criteria were age > 18 years and ventral thoracic tumor component.

Three patients underwent a simultaneous retropleural thoracotomy and posterior spinal approach, through a single incision, for the resection of dumbbell (intradural and extradural) schwannomas. Mean age was 49.7 years and 2 patients were female. All patients were neurologically intact at baseline. Lesions were 4-8.2 cm in the largest dimension (mean 6.1 cm).

The combined retropleural thoracotomy-posterior spinal approach provides safe and sufficient access for resection of large dumbbell schwannomas of the thoracic spine.
