BACKGROUND
Double-door laminoplasty is an effective method in treating patients with cervical spondylosis. Many patients with cervical spondylosis experience a set of atypical symptoms such as vertigo and tinnitus, and wish to know if the surgical treatment for cervical spondylosis can also alleviate those symptoms. The current research was carried out to investigate if atypical symptoms can be alleviated in patients who received laminoplasty for the treatment of cervical spondylosis.
METHODS
One hundred ninety patients who received laminoplasty to treat cervical spondylotic myelopathy/radiculopathy in our center and complained about one or more of the atypical symptoms before the surgery were followed for a mean of 61.9 months (from 39 to 87 months) after the surgery. Severity scores were retrospectively collected by follow up outpatient visits or phone interviews. The data was calculated based on patient feedback on the frequency and severity of those symptoms before the surgery and at last follow up, and were compared by paired sample t-tests.
RESULTS
Most patients reported that the atypical symptoms such as vertigo (P <0.001), nausea (P <0.001), headache (P <0.001), tinnitus (P = 0.001), blur vision (P = 0.005), palpitation (P <0.001) and gastrointestinal discomfort (P = 0.001) were significantly alleviated at the last follow up; there was no significant change in the severity of hypomnesia (P = 0.675).
CONCLUSIONS
Double-door laminoplasty can significantly alleviate most of the atypical symptoms in patients with cervical spondylosis. Further research is needed to explore mechanisms underlying this extra benefit of laminoplasty.
