Considering the growing burden of chronic pain and the urgent need for effective, minimally invasive treatments, rhizotomy has gained prominence as a viable therapeutic option. However, the variability in techniques, such as endoscopic, radiofrequency, and chemical rhizotomy, and the differing outcomes across patient populations underscore the necessity for a comprehensive evaluation of its efficacy. This study aims to systematically review the therapeutic effectiveness of various rhizotomy techniques in managing chronic pain, focusing on their application in conditions like lumbar facet joint pain, trigeminal neuralgia, and cancer-related pain. To achieve this, a narrative literature review was conducted, employing a structured methodology based on established guidelines from experts in the field. The review covered studies published between 2000 and 2023, sourced from reputable academic databases such as PubMed, Scopus, and Web of Science, using specific descriptors like "rhizotomy," "pain management," "endoscopic rhizotomy," and "radiofrequency." The inclusion criteria were stringent, focusing on studies that reported quantitative or qualitative outcomes related to pain relief, complications, and the impact on patients' quality of life following rhizotomy. The results of this review indicate that rhizotomy, particularly the endoscopic and radiofrequency variants, consistently provides significant pain relief and functional improvement across various conditions. The long-term benefits of selective dorsal rhizotomy, especially in reducing pain and improving function in patients with spastic cerebral palsy, were notably highlighted. However, the review also points out that the efficacy of rhizotomy can vary depending on the specific technique employed, the underlying condition being treated, and individual patient characteristics. This comprehensive analysis allows us to conclude that rhizotomy is indeed a valuable option in the realm of pain management, offering substantial benefits in terms of both pain relief and enhanced quality of life. Nevertheless, it also emphasizes the need for further research to optimize these techniques and better understand the factors that influence patient outcomes, ultimately paving the way for more personalized and effective pain management strategies.
