Summary
Three-dimensional CT (3D-CT) precisely diagnosed temporomandibular joint (TMJ) ankylosis, improving surgical planning for traumatic injuries. This advanced imaging technique clearly visualized lesion extent, leading to successful patient outcomes.
Area of Science:
- Dentistry
- Radiology
- Orthopedics
Background:
- Temporomandibular joint (TMJ) diseases traditionally diagnosed using roentgenographic methods.
- Conventional techniques include tomography, panoramic radiography, and CT scans.
Observation:
- A case of TMJ ankylosis resulting from traumatic injury is presented.
- Three-dimensional CT (3D-CT) was utilized as a presurgical diagnostic tool.
- Conventional radiography indicated bilateral mandibular lesions; CT suggested more severe right-sided involvement.
Findings:
- 3D-CT reconstruction clearly delineated the size and extent of TMJ ankylosis lesions.
- Surgical intervention focused initially on the more severely affected right side.
- Condylectomy and autogenous costochondral grafting on the right side significantly improved mouth opening.
Implications:
- 3D-CT offers superior visualization for diagnosing TMJ ankylosis compared to conventional methods.
- Precise diagnosis with 3D-CT facilitates tailored surgical planning and improved treatment outcomes.
- This case highlights the value of advanced imaging in managing complex TMJ disorders.
