Morphological and Positional Assessment of Condyle in Facial Asymmetry Patients with or without Temporomandibular Disorders: A CBCT Study
**Background:**Facial asymmetry can influence not only dental occlusion but also the morphology and position of the temporomandibular joint (TMJ), possibly leading to temporomandibular disorders (TMD). Variations in condylar position and shape are believed to play a critical role in these conditions. Cone Beam Computed Tomography (CBCT) is a valuable diagnostic tool for evaluating these structures in three dimensions with reduced radiation exposure.
**Aim:**To evaluate and compare the positional and morphological changes of the mandibular condyle in patients with facial asymmetry, with and without TMD, using CBCT.
Objectives:
- Assess condylar morphology and position in symmetrical patients without TMD (control group).
- Assess the same parameters in asymmetrical patients with TMD.
- Assess the same parameters in asymmetrical patients without TMD.
- Compare findings across all three groups.
Study Design:
- Type: Prospective, observational, multi-arm, cross-sectional study
- Sample size: 66 participants (22 in each group)
- Grouping: Based on presence of facial asymmetry and TMD
- Method: Clinical exam, validated TMD questionnaire, CBCT imaging
Primary Outcome:
- Condylar positional and morphological parameters on CBCT, including joint spaces, condylar dimensions, and alignment.
Secondary Outcome:
- Association of condylar variations with facial asymmetry and presence/absence of TMD symptoms.
**Time Points:**All outcomes are assessed once at baseline, during initial CBCT scan and questionnaire assessment.
Statistical Analysis:
- Chi-square test
- ANOVA / Kruskal-Wallis test
**Conclusion (anticipated):**This study aims to provide insights into how condylar morphology and position vary with facial asymmetry and TMD, potentially aiding in early diagnosis and treatment planning using CBCT.
