Objectives: To evaluate cervical ossification of posterior longitudinal ligament (OPLL) with computed tomography (CT) in the southeast of Turkey area. Materials and Methods: We retrospectively evaluated cervical CT of 2610 patients in our databese (1806 males, 804 females; age range 1-100 years). OPLL was present in 135 patients. These 135 patients were evaluated according to the new CT classification. Results: We show OPLL in 135 patients (90 [66.6%] males, 45 [33.3%] females; mean age 56.84 ±

... 15.6 [range 26-100] years). Using classification A, 84 (62.2%) patients had non-bridge OPLL, while 51 (37.8%) had bridge OPLL. Using the axial classification, 114 (84.5 %) patients had the central type and 21 (15.5%) patients had lateral type OPLL. Conclusions: Our population has different OPLL features compared to previous studies. We believe that our study will contribute a new data related to a different population in the literature of OPLL prevalence
