Abstract:
Although the operation for the ventral lesion of craniovrtebral junction and atlantoaxial area is considered difficult to perform, the transoral approach made it safer and easier. The authors report 10 cases(9 patients) treated by the transoral approach for the lesion of craniovertebral junction over the past 13 years at the Ajou University Hospital and the Presbyterian Medical Center. Of these 10 cases, there were 4 odontoid type II fractures, 1 atlantoaxial dislocation, 1 os odontoideum, 1 chordoma at lower clival area, 1 rheumatoid arthritis, 1 epidural abscess and 1 wound revision due to slippage of grafted bone after clivoaxial fusion. The surgical methods included 4 cases of anterior decompression and clivoaxial fusion, 2 cases of anterior decompression and C1-2 interarticular joint fusion, 1 case of anterior decompression and clivoaxial fusion followed by posterior fusion, and 3 cases of anterior decompression and posterior fusion. In nonreducible atlantoaxial dislocation or ventral cord compression le sion, if the clivoaxial angle was less than 120 degree, the transoral approach was selected. The appropriate surgical approach must be selected according to the degree of compression of the neural tissue involving the craniovertebral junction and atlantoaxial dislocation.
