Final answer:
Damage to the infraorbital nerve in a patient with a blowout fracture may cause paresthesia in the gums, upper lips, and cheeks. Weakness in activities like brushing hair may occur if the surrounding muscles or nerves are affected. correct answer is C) paresthesia in the gums, upper lips and cheeks .
Step-by-step explanation:
The neurological findings that may occur with damage to the infraorbital nerve in a patient with a blowout fracture include:
- Paresthesia in the gums, upper lips, and cheeks. This is due to sensory loss caused by damage to the nerve.
- Weakness in activities like brushing hair may not be directly related to damage to the infraorbital nerve. However, it could be indirectly affected if the damage affects the surrounding muscles or nerves that are involved in these activities.
- Inability to wrinkle the forehead is not associated with damage to the infraorbital nerve.
- The symptoms mentioned in option D, weakness of the legs, progressing to total paralysis of all four limbs, facial muscles, and eyes. Loss of reflexes, are not specific to infraorbital nerve damage and suggest a more severe neurological condition.
The neurological findings that may occur with damage to the infraorbital nerve from a blowout fracture include paresthesia in the gums, upper lips, and cheeks. An infraorbital nerve injury would not typically cause weakness in everyday activities like brushing hair, inability to wrinkle the forehead, or lead to weakness and paralysis of limbs or facial muscles, as this nerve is primarily sensory and affects the midface region. The correct answer to expect on a neurological exam following such an injury would be (C) paresthesia in the gums, upper lips, and cheeks.
