Repeated dislocation of the condyle can be treated by intentional fracture of the zygomatic arch and reunion. This procedure is called as
## **Core Concept**
The question pertains to a surgical procedure used to treat recurrent dislocation of the mandibular condyle. This condition can lead to significant discomfort and functional impairment. The procedure in question involves modifying the zygomatic arch to prevent repeated dislocation.
## **Why the Correct Answer is Right**
The procedure described is known as **Eminectomy**. It involves the intentional fracture and subsequent modification of the **zygomatic arch** (or more specifically, the articular eminence of the temporal bone where the condyle articulates) to prevent the mandibular condyle from dislocating anteriorly. This is a recognized surgical treatment for recurrent temporomandibular joint (TMJ) dislocation when conservative treatments have failed.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is blank and does not provide a viable alternative.
- **Option B:** While not specified, any other option not related to eminectomy would be incorrect because they do not accurately describe the procedure for treating recurrent TMJ dislocation by modifying the zygomatic arch or articular eminence.
- **Option C:** Similarly, another unspecified option would be incorrect for not accurately representing eminectomy.
- **Option D:** This option is also blank and does not offer a correct alternative.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that eminectomy is considered for patients with recurrent TMJ dislocation who have failed conservative management. The goal is to reduce the height of the articular eminence, thereby preventing the condyle from moving anteriorly out of the joint. This procedure highlights the importance of surgical intervention in specific cases of TMJ disorders.
## **Correct Answer:** B. Eminectomy.
