Transoral Approach To CV Junction - Odontoidectomy - Case Series
Journal Title: Chettinad Health City Medical Journal - Year 2017, Vol 6, Issue 1
Abstract
BACKGROUND: The endoscopic transoral approach offers a risk-free access to midline and ventral lesions of the craniovertebral junction. Benefits of this approach include 1) Direct exposure to ventral lesions (bony pathology, granulation tissue etc) possible through this route alone; 2) Avascular plane of dissection through median pharyn- geal raphe and clivus; 3) Less injury to brainstem structures as head is kept in an extended position. METHODS: Endoscopic transoral approach (ventral route) was used to decompress the craniovertebral junction lesions. The odontoid process was drilled, to remove compression on the spinal cord. Stabilization of the cervical vertebra was done with occipitocervical fusion in the following week. RESULTS: Cervicomedullary junction decompression through transoral odontoidectomy was done successfully in 7 patients from February 2013 to June 2014 with minimal or no complications. On a 1-2 year follow-up, there was no evidence of CVJ instability and patients had improvement of neurological function. CONCLUSION:The endoscopic transoral odontoidectomy is a better surgical technique for ventral lesion of the craniovertebral junction.
