Long-Term Outcomes of Different Surgical Techniques for Sacral Tarlov Cysts: A Prospective Cohort Study

Brief Summary The goal of this observational study is to evaluate the long-term outcomes of different surgical techniques for sacral Tarlov cysts in adult patients aged 18-75 years diagnosed with symptomatic sacral Tarlov cysts. The main questions it aims to answer are: * Does one surgical technique result in better pain relief (measured by VAS score) and functional recovery (measured by JOA score) compared to others? * How do different surgical techniques impact the long-term recurrence rate and complication rate? Researchers will compare three surgical techniques: 1. Partial cyst wall resection with nerve root sleeve plasty. 2. Partial cyst wall resection with nerve root sleeve reinforcement and reconstruction. 3. Autologous fat/muscle with fibrin glue microscopic cyst filling. Participants will: * Undergo one of the three surgical procedures based on clinical indications. * Complete preoperative and postoperative assessments, including pain and functional scoring, as well as MRI evaluations at baseline and during follow-up. * Participate in a follow-up program for up to 2 years to monitor outcomes and recurrence.
