Various neurosurgical options are available, each with its own set of advantages and disadvantages. We investigated using the modified McKenzie-Dandy operation for a patient with CD who failed selective peripheral denervation (SPD). Case Description: A 42-year-old man presented left-sided rotational torticollis for 3 years. He was referred for surgery after treating with a variety of oral medications and repeated botulinum toxin injections that became ineffective. For the first operation, the patient underwent SPD (modified Bertrand’s operation); unfortunately, the postoperative outcome was unsatisfactory, and the operation was considered a failure. After his symptoms did not improve after 6 months, the modified McKenzie-Dandy operation was performed. Immediately following surgery, he experienced satisfactory outcomes. He was able to resume his normal activities and employment after 1 month after recovering from his temporary swallowing difficulties. He only complained of minor neck pain and no recurrence was observed after 3 years follow-up. Conclusion: For patients who have failed SPD, a modified McKenzie-Dandy procedure is a feasible and effective option. The procedure is relatively safe when performed properly, and the long-term effects can be maintained.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/059d83ad-2944-4940-9cc3-020de8f4bbc3/featured/hero-cropped-1781561664899.jpg","publishDate":"2022-01-29T00:00:00.000Z","doi":"10.25259/SNI_844_2021","categories":["General Neurosurgery","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/01/11365/SNI-13-31.pdf"}
