A surgeon removed section of tissues how would he confirm that cut margin doesn't contain any suspicious tissue intraoperatively?

1) Punch biopsy
2) Brush biopsy
3) Frozen section
4) Exfoliative cytology

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

The�frozen section�procedure is the examination of tissue to make a rapid microscopic diagnosis of a specimen while surgery is taking place.�It is often used in oncological surgery to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin.�

The technical name for this procedure is cryosection. The report given by the pathologist is usually limited to a "benign" or "malignant diagnosis, and communicated to the surgeon operating via intercom. When operating on a previously confirmed malignancy, the main purpose of the pathologist is to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin

Advantages of frozen section biopsy:
If more tissue is needed to make an accurate diagnosis, the surgeon is able to obtain an additional sample, avoiding a second operation.
If the tissue is determined to be cancerous and is amenable to surgery, the mass can b removed at that time
If the tissue is determined to be benign (not cancerous), then the mass may not always need to be removed and the surgery can end.

A patient has mandibular nerve neuralgia with herpes zoster infection within mandibular division of left trigeminal nerve. Patient has difficulty on protrusion and on protrusion mandible deviates to left side. Which muscle is most probably affected:
1) LP on left side
2) LP on right side
3) MP on left and LP on left
4) MP on right and LP on left

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

The lateral pterygoid (LP) muscle on the left side is the most probable muscle affected.�The trigeminal nerve innervates the muscles of mastication, including the lateral pterygoid.�When the left lateral pterygoid is paralyzed due to the nerve lesion, the functioning right lateral pterygoid muscle pulls the mandible to the right during protrusion attempts, causing the jaw to deviate to the affected (left) side upon opening or protrusion.
