Summary

The goal of this clinical trial is to learn if cervical single-door laminoplasty via the intermuscular space approach can better prevent axial symptom while reaching equal neurological outcome than the conventional approach in adults patients with cervical spondylotic myelopathy. The main questions it aims to answer are: * Can cervical single-door laminoplasty via the intermuscular space approach better prevent axial symptom than the conventional approach? * Can cervical single-door laminoplasty via the intermuscular space approach reach the neurological outcome not second to the conventional approach? If there is a comparison group: Researchers will compare the intermuscular space approach and the conventional approach of cervical single-door laminoplasty to see if the intermuscular space approach better prevent axial symptom. Participants will: * Received cervical single-door laminoplasty via the intermuscular space approach or the conventional approach once meet the indication. * Visit the clinic 1 month, 3 months, 6 months, 1 year and 2 years after the surgery. * Keep a diary of their symptoms and other unexpected conditions.

Conditions

• Cervical Spondylotic Myelopathy

Interventions

Type	Name	Description
PROCEDURE	Expansive open-door laminoplasty via intermuscular space approach	The cervical laminoplasty via intermuscular space approach will apply bilateral blunt dissection to create the operative space between capital semispinalis muscle and cervical semispinalis muscle
PROCEDURE	cervical single-door laminoplasty via the conventional approach	The cervical laminoplasty via the conventional approach will apply median dissection of the cervical spinous ligament and seperate muscles to expose the whole lamina of cervical vertebrae.
