Background: Spinal extradural arachnoid cysts are rare cerebrospinal fluid filled meningeal lesions producing symptoms by compressing neural structures or as expansile bony lesions. The aim of our research is to systematically review and discuss the various surgical techniques, outcomes, patient demographics, symptomatology, and neurological findings in our patient. Materials and Methods: We have studied 11 cases of symptomatic extradural spinal arachnoid cysts managed surgically at our institute from 2019 to 2023. The history, clinical presentation, radiological findings, operative findings, surgical techniques, and outcomes were retrospectively analysed. The patients were evaluated for recurrence if any at the 3rd-month, 6th-month, and 1-year follow-up period. Results: Progressive neurological motor weakness and radiculopathy were the chief presenting complaints. Magnetic resonance imaging was the main imaging technique, with 7 dorsal, 2 dorsolumbar, 1 cervicodorsal, and 1 cervical cyst with an average size of 6 ± 2 cm length. Surgical technique was complete excision or marsupialization of the cyst with obliteration of the dural communication. All patients had favourable outcomes and no recurrences. Conclusion: Symptomatic patients have good results with complete excision of the cyst and obliteration of the subarachnoid dural communication with metal clips, which ensures low or no recurrences.
