Background: Surgical treatment of cervical vertigo has been rarely reported. This is the first
retrospective study to evaluate the clinical outcomes of percutaneous disc decompression with
coblation nucleoplasty (PDCN) for treatment of cervical vertigo.
Objectives: To assess the clinical outcomes of patients with cervical vertigo who failed to improve
with conservative care and who were subsequently treated with PDCN.
Study Design: This study used a retrospective design.
Setting: The research was conducted within an interventional vertigo management and spine
practice.
Methods: Seventy-four consecutive patients with cervical vertigo underwent PDCN and were
followed for at least one year. Outcome measures included the dizziness intensity Visual Analog
Scale (VAS), dizziness frequency, the Dizziness Handicap Inventory (DHI), and neck pain intensity.
Clinical efficacy was assessed by rating scale and the modified MacNab evaluation criteria. Surgical
complications during the operation and follow-up were also recorded.
Results: The vertigo VAS score, frequency of dizziness, DHI, and neck pain intensity were all
decreased significantly from evaluation before surgery to one week after surgery and to the last
follow-up, giving a mean effective rate of 94.6% one week after surgery and 90.6% at the last
follow-up. Good to excellent results were attained in 85.1% of these patients one week after
PDCN and in 75.7% of the sufferers at the last follow-up (P < 0.001). There were 5 patients with
transient adverse effects (6.25%) reported within the first month after surgery; they all recovered
after conservative treatment. No neurological complications were found and no patient went on
to spinal fusion surgery thereafter.
Limitations: The rate of follow-up was 70% and a placebo effect cannot be excluded. There is
no gold standard for the diagnosis and treatment of cervical vertigo so far.
Conclusion: The clinical outcomes of PDCN for cervical vertigo were satisfactory in both the
early and late postoperative period. PDCN is an effective, low-complication, minimally invasive
procedure used to treat cervical vertigo. Further prospective randomized controlled trials are
essential to verify this conclusion.
