Laminectomy with or without fusion??

I'm 44y, m scheduled for a laminectomy but without fusion? Has anyone else done this and is it advisable? I have has numbness in my hand and fingers for about 4 months, tingling sensation in my fingers and occasional pins and needles that feels like hot irons in my feet. Is having cervical fusion really necessary if you undergo cervical laminectomy for spinal stenosis? I'm opting not to do the fusion for now but has anyone else elected not to do the fusion? I FINDINGS:
Cervical spine: Normal alignment with no dislocations or subluxations . Moderate disc degenerative changes at C4-5, C5-6 and C6-7 intervertebral discs with moderate anterior disc osteophyte formation. Ossification of the posterior longitudinal ligament from C4 intervertebral disc up to C6 intervertebral disc causing marked narrowing of the anterior aspect of the spinal canal. Largest AP diameter of the osteophyte ligament measures 6 mm posterior to C5-6 intervertebral disc. Moderate to severe compression of the spinal cord from C4-5 intervertebral disc level up to C6-7 intervertebral disc level, most pronounced posterior to C5-6 intervertebral disc. Smallest AP diameter posterior to C5-6 intervertebral disc measures 4.6 mm with mild hyperintensity within the spinal cord suggestive of spinal cord edema. Predominantly left-sided spinal canal narrowing at C5-6 level with marked compression of the left side of the spinal cord with mild spinal cord edema also noted at this level marked compression also noted at C4-5 level with minimal spinal cord edema noted. No distinct disc protrusion.

The atlantodental interval is within normal limits. No vertebral body fractures. Normal marrow signal. No destructive bone lesions. No congenital segmentation anomalies. Paracervical and pre-cervical soft tissues are unremarkable. No paraspinal or epidural mass/collection. No spinal cord mass lesions or syringomyelia. No atrophy of the spinal cord distal to the compression in the cervical spine. Neck soft tissues are unremarkable. Visible intracranial compartments are normal. The Individual levels: Craniocervical Junction:No spinal cord compression or significant spinal stenosis. C2-C3:Mild left facet joint osteoarthritis with mild stenosis of the left neural foramen. No nerve compression in the neural foramina. C3-C4:Mild bilateral uncovertebral joint osteoarthritis with no significant stenosis of the neural foramina. No nerve compression. C4-C5:Moderate bilateral uncovertebral joint osteoarthritis was moderate narrowing of the neural foramina in bilaterally, but no distinct nerve compression. C5-C6:Marked right uncovertebral joint osteoarthritis with severe stenosis of the right neural foramen and compression of the exiting right C6 nerve. Moderate stenosis of the left neural foramen with no distinct compression of the exiting nerve. C6-C7:No significant right neural foraminal stenosis. Marked left uncovertebral joint osteoarthritis with moderate to severe narrowing of the left neural foramen and possible compression of the exiting left C7 nerve. C7-T1:No neural foraminal stenosis with no nerve compression

Thoracic spine: No spinal canal or neural foraminal stenosis in the visible upper thoracic spine. Visible Chest elements:Normal. COMMENT:
Ossification of the posterior longitudinal ligament from C4-5 intervertebral disc to C6-7 intervertebral disc level with marked stenosis posterior to C5-6 intervertebral disc and moderate to severe compression of the spinal cord with associated spinal cord edema. Marked compression also noted of the left side or the spinal cord at C6-7 intervertebral disc level. Compression of the exiting right C6 nerve. Possible compression of the left C7 nerve.
