Minimally invasive video-assisted thyroidectomy can be done in all except
**Core Concept**
Minimally invasive video-assisted thyroidectomy (MIVAT) is a surgical technique that involves the use of a camera and specialized instruments to perform thyroid surgery through small incisions. This approach is used to reduce scarring and promote faster recovery. The key principle being tested is the anatomical suitability of the thyroid gland for MIVAT.
**Why the Correct Answer is Right**
The correct answer is related to the anatomical constraints of the thyroid gland. MIVAT is typically performed for hemithyroidectomies or lobectomies, which involve removing only one lobe of the thyroid gland. The procedure is generally contraindicated in cases where the entire thyroid gland needs to be removed, such as in the case of Graves' disease or thyroid cancer that requires a total thyroidectomy. This is because the entire gland must be mobilized and retracted to allow for the removal of the diseased lobe, which is not feasible through small incisions.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided, so we'll skip it.
* **Option B:** MIVAT can be performed for thyroid nodules, especially those that are unilateral and can be safely removed through a small incision. This option is not the correct answer.
* **Option C:** This option is not provided, so we'll skip it.
* **Option D:** This option is not provided, so we'll skip it.
**Clinical Pearl / High-Yield Fact**
MIVAT is generally contraindicated in cases where the patient has a history of thyroid surgery or has a significantly enlarged thyroid gland, as the increased tissue makes the procedure more challenging and increases the risk of complications.
**Correct Answer:** A.
