The relationship between temporomandibular joint-space asymmetry and craniovertebral position in unilateral temporomandibular joint osteoarthritis: A cone-beam computed tomography study Ceyda Gizem Topal (25146227) Osman Yalçın (25146230) Hatice Tetik (25146233) Ömer Onur Gümüş (25146236) Umut Pamukçu (25146239) Space Science Cell Biology Physiology Biotechnology Immunology Biological Sciences not elsewhere classified Mathematical Sciences not elsewhere classified Science Policy Temporomandibular joint osteoarthritis cone-beam computed tomography craniovertebral junction joint space asymmetry <p><b>Objective</b>: This retrospective cone-beam computed tomography (CBCT) study examined whether temporomandibular joint (TMJ) space asymmetry is associated with upper cervical (C0–C1–C2) position in unilateral TMJ osteoarthritis (TMJOA).</p> <p><b>Methods</b>: Seventy-nine patients (40 controls without definite OA in either TMJ, 39 unilateral), classified using RDC/TMD criteria, had the joint spaces, a condylar ratio, and craniovertebral parameters measured and expressed as side-to-side and affected-versus-unaffected asymmetries.</p> <p><b>Results</b>: Within the unilateral group, superior joint-space asymmetry correlated moderately with occipital condyle–atlas–axis (OCAA) asymmetry (ρ = 0.50, <i>p</i> = .001), surviving false-discovery-rate correction; the whole-sample correlation was weaker (ρ = 0.24).</p> <p><b>Conclusion</b>: Superior joint-space asymmetry may represent an imaging correlate of craniovertebral position, not a diagnostic marker. These findings are preliminary and require replication; interpretation is limited by the retrospective design, an approximately six-year age difference between groups, and the absence of clinical or symptom data.</p> 2026-09-30T20:39:49Z Text Journal contribution 10.6084/m9.figshare.34036907.v1 https://figshare.com/articles/journal_contribution/The_relationship_between_temporomandibular_joint-space_asymmetry_and_craniovertebral_position_in_unilateral_temporomandibular_joint_osteoarthritis_A_cone-beam_computed_tomography_study/34036907 CC BY 4.0
