You are surgeon posted at CHC. A patient of head injury come to you with rapidly deteriorating sensorium and progressive dilation and fixation of pupil. Neurosurgeon and CT scan is not available. You decide to make a burr hole to emergently relieve the intracranial pressure. Which of the following sites will you choose

**Core Concept**
The question tests the ability to manage **increased intracranial pressure (ICP)** due to a head injury, specifically in a resource-limited setting without access to a neurosurgeon or CT scan. The principle being tested is the emergency relief of **intracranial hypertension**.

**Why the Correct Answer is Right**
In the absence of a neurosurgeon and CT scan, the decision to perform an emergency **burr hole** procedure is based on clinical signs of **brain herniation**, such as deteriorating sensorium and progressive dilation and fixation of the pupil. The correct site for the burr hole is crucial to effectively relieve the pressure.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it is not the standard site for emergency burr hole in the context of suspected unilateral hematoma.
**Option B:** Incorrect as it does not address the likely lateralized intracranial pressure.
**Option C:** Incorrect because it is not typically the first choice for emergency burr hole.
**Option D:** Incorrect as the specific location is not provided, but typically, the correct answer involves a site that allows for the relief of pressure from an epidural or subdural hematoma.

**Clinical Pearl / High-Yield Fact**
In emergency situations where increased ICP is suspected due to head trauma, the **temporoparietal** region is often the site of choice for a burr hole because it allows for the potential evacuation of an epidural hematoma, which commonly occurs in this area.

**Correct Answer:** Correct Answer: D. Temporoparietal region.

✓ Correct Answer: C. In the left temporal region if no localising sign is found
