**Question:** Sign of basal skull fracture is all Except

A. Loss of consciousness
B. Commonly present
C. Less severe than other types of skull fractures
D. Absent in infants and young children

**Core Concept:** Basal skull fracture is a type of skull fracture involving the base of the skull, which includes the ethmoid, sphenoid, and frontal bones. The clinical presentation and management of basal skull fractures can be different from other types of skull fractures due to their unique characteristics.

**Why the Correct Answer is Right:** The correct answer, "Less severe than other types of skull fractures," is incorrect because basal skull fractures can result in significant intracranial complications and are often accompanied by other types of skull fractures or injuries due to the high-energy trauma involved.

**Why Each Wrong Option is Incorrect:**

A. Loss of consciousness (Option A) is often present in basal skull fractures, which can lead to severe head injuries and intracranial complications.
B. Basal skull fractures can present with various clinical signs and symptoms, making the statement "commonly present" incorrect.
C. The severity of basal skull fractures cannot be generalized as "less severe than other types of skull fractures," as they can lead to severe complications.
D. Absence of signs and symptoms in infants and young children is incorrect as basal skull fractures can occur in any age group and can cause complications.

**Clinical Pearl / High-Yield Fact:** In basal skull fractures, the high-energy trauma can lead to significant complications and should not be considered less severe compared to other types of skull fractures. Infants and young children can also be affected, making this statement inaccurate. It is essential for medical professionals to have a high index of suspicion for basal skull fractures in patients with head injuries, regardless of age or severity, to ensure appropriate diagnosis and management.
