Abstract
Objective: To evaluate the effect of minimally invasive ipsilateral laminotomy for the treatment of lower cervical Schwannomas. Subject and method: A retrospective study. This study include 48 lower cervical Schwannomas were treated from January 2019 to January 2022 at 108 Military Central Hospital. The clinical course preoperative and postoperative (at discharged and 6 months postoperative) was documented using the visual analog scale (VAS), Karnofsky score (KPS) and the Klekamp-Samii score system. Site, size and extension of the lesions were obtained through MRI, according to Sun and Pamir’s classification. Result: Hemilaminectomy was performed in 17 cases, subtotal hemilaminectomy in 13 cases, interlaminar foraminotomy in 18 cases. There were 79.92% total removal and 20.83% gross total removal of the lesion. At discharge, neurological improvement was observed in 46 patients and all patients demonstrated reduction of VAS score and improvement of KPS and Klekamp-Samii’s score. Postoperative X-ray imaging revealed all patients had no signs of spinal instability. Conclusion: The minimally invasive ipsilateral laminotomy may effectively be used instead of traditional laminectomy in the treatment of lower cervical especially schwannomas. This technique may helping to complete removal and preventing postsurgical spinal instability.
