Summary
Patients with skull base tumors or post-surgery may experience cranial nerve deficits affecting swallowing and speech. Evaluation typically involves history, physical exam, and videofluoroscopy, with other tests used less often.
Area of Science:
- Neurology
- Otolaryngology
- Neurosurgery
Background:
- Cranial base tumors can cause cranial neuropathies.
- Skull base surgery can lead to cranial nerve deficits.
- Deficits in cranial nerves IX, X, XI, and XII significantly impact patient morbidity.
Purpose of the Study:
- To outline the standard evaluation for patients with suspected skull base lesions.
- To describe the assessment of cranial nerve deficits post-skull base surgery.
Main Methods:
- Standard evaluation includes comprehensive history and physical examination.
- Bedside examination and videofluoroscopy are key components.
- Fiberoptic endoscopic examination of swallowing safety, ultrasound, and manofluorography are supplementary methods.
Main Results:
- Cranial nerve deficits (IX, X, XI, XII) are common in patients with cranial base tumors or after surgery.
- A thorough clinical assessment is the primary diagnostic approach.
- Videofluoroscopy is a frequently utilized imaging modality.
Conclusions:
- Prompt identification and evaluation of cranial nerve deficits are crucial for managing patients with skull base pathology.
- A systematic approach combining clinical assessment and targeted investigations ensures comprehensive patient care.

01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
