Introduction:

In this prospectively designed study, it was planned to present an Open Door Laminoplasty (ODL) series, to discuss effectiveness of this approach and to investigate correlation between preoperative cervical canal cross-sectional area and recovery rate of patients.

Patients and Method:

A 47-patient group which had minimum 36 months follow-up was included in the study. All patients were performed a standard ODL. Preoperative and various postoperative times clinic and radiologic parameters were compared statistically, and recovery rates (RR) of patients were calculated.

Results:

RR of patients was statistically significant by Friedman’s test. It cannot be found any statistical relation between preoperative cross sectional area (CSA) and preoperative clinic by statistical significance tests. That RR decreases as preoperative symptom duration increases is remarkable.

Conclusions:

ODL is an effective and safe way to reduce symptoms of degenerative cervical myelopathy due to OPLL.
