BACKGROUND: Reankylosis is a frequent pathology in patients who are operated for post-traumatic temporomandibular joint (TMJ) ankylosis. In the current practice, ankylosing spondylitis attacks are monitored with the increases in neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). In this study, such a relation between TMJ reankylosis and increase in these ratios was evaluated. METHODS: Patients who were operated between January 2010 and December 2019 for unilateral or bilateral TMJ ankylosis were included in this study. Temporomandibular gap arthroplasty with an interpositional silicone block was performed for each patient by the same operative team. Each patient had standard physiotherapy. All ages and genders were included in the study. Due to the complete blood count differences between children and adults, 18 years of age was used as a cutoff between the groups. A need for reoperation was accepted as reankylosis. The NLR and PLR of children without and with reankylosis and adults without and with reankylosis were compared. RESULTS: Twenty-nine children and 38 adults were included in the study. Mean age of the children and adults were 10.8 and 37.3 years, respectively. Eleven children and eight adults had reankylosis. In patients with reankylosis, NLR and PLR were high significantly, regardless of age. In children, PLR was significantly higher in reankylosis patients. In adults, NLR was significantly higher in reankylosis patients. CONCLUSION: PLR and NLR may be utilized for predicting reankylosis, respectively, in children and adults who were operated for ankylosis due to TMJ fractures.
