Abstract:
The aim of this paper was to determine the optimal needle depth for temporomandibular joint (TMJ) arthrocentesis using magnetic resonance imaging (MRI), with the aim of improving procedural safety and efficacy in clinical practice. A retrospective analysis of 264 TMJ MRIs from 132 patients at Istanbul Medipol Mega University Hospital was conducted. T2-weighted MRI sequences were utilised to measure distances from skin to joint capsules at varying needle entry points, applying the double puncture technique. The study adhered to ethical standards with appropriate approvals. The analysis revealed significant gender-related variations in needle depths (females showing shorter distances than males, p < 0.05). No significant gender differences were found in condylar angles. An inverse correlation between age and condylar angle suggested age-related anatomical changes. Crucially, a 20 mm needle depth was identified as safer and more effective than the previously recommended 25 mm. This study underscores the necessity of revising needle depth to 20 mm in TMJ arthrocentesis. These findings hold significant implications for improving procedural safety and catering to demographic variations.
Insights
This study recommends a 20 mm needle depth for temporomandibular joint (TMJ) arthrocentesis, improving safety and effectiveness. Findings show gender-based variations in optimal needle depth for TMJ procedures.
Area of Science:
- Medical Imaging
- Orthopedics
- Anatomy
Background:
- Temporomandibular joint (TMJ) arthrocentesis is a common procedure.
- Current needle depth recommendations may not account for anatomical variations.
- Improving procedural safety and efficacy is crucial for patient outcomes.
Purpose of the Study:
- To determine the optimal needle depth for TMJ arthrocentesis using MRI.
- To enhance the safety and effectiveness of TMJ arthrocentesis in clinical practice.
- To investigate demographic variations influencing needle depth requirements.
Main Methods:
- Retrospective analysis of 264 TMJ MRIs from 132 patients.
- Utilized T2-weighted MRI sequences to measure skin-to-capsule distances.
- Applied the double puncture technique for needle entry point assessment.
Main Results:
- Identified a 20 mm needle depth as safer and more effective than the previous 25 mm recommendation.
- Revealed significant gender-related variations in required needle depths (females: shorter distances).
- No significant gender differences in condylar angles; age inversely correlated with condylar angle.
Conclusions:
- Revising the recommended needle depth to 20 mm for TMJ arthrocentesis is necessary.
- Findings support tailoring needle depth based on demographic variations for improved procedural outcomes.
- This study provides critical data for enhancing the safety and efficacy of TMJ arthrocentesis.
