Case reports demonstrate sacral multifidus plane block provides effective anesthesia for coccygectomy, suggesting a viable alternative approach.
Coccygodynia may arise from traumatic or nontraumatic causes and can become refractory to conservative treatments, for which coccygectomy may be required. Providing effective anesthesia for this procedure can be challenging. These case reports describe the use of an ultrasound-guided sacral multifidus plane block (SMPB) as the primary anesthetic technique for coccygectomy in two patients with chronic coccygodynia. SMPB provided adequate surgical conditions and postoperative analgesia without conversion to general anesthesia or the need for additional intraoperative analgesics. These cases suggest that SMPB may be considered as an alternative anesthetic approach in selected patients.
