To present a small case series reporting the outcomes of surgical treatment for myelopathy caused by cervical ossification of the ligamentum flavum (OLF). ⋯ A high rate of adherence to the dura was observed in patients with myelopathy caused by cervical OLF. Bilateral laminectomy and removal of the lesions, without extensive decompression of adjacent segments, provides an optimistic prognosis.

Comparative Study
A comparative anatomic study of a modified temporal-occipital transtentorial transpetrosal-ridge approach and a transpetrosal presigmoid approach.
To evaluate the anatomic features of a modified temporal-occipital transtentorial transpetrosal-ridge approach versus the conventional approach for surgery of petroclival tumors. ⋯ The modified temporal-occipital transtentorial transpetrosal-ridge approach is a feasible surgical approach to remove petroclival tumors.

To introduce a fixation device composed of C1-2 transarticular (TA) screws and C1 hooks and explore its indication and clinical outcome for os odontoideum with atlantoaxial dislocation (AAD). ⋯ When appropriate patients are selected, C1-2 TA screws combined with C1 hooks can be used to treat os odontoideum with AAD effectively with a relatively simple procedure resulting in excellent biomechanical strength and high bone fusion rate. Preoperative planning is crucial for the management of os odontoideum with AAD.
