Cranial Monitoring

Cranial Nerve Monitoring is a form of Intraoperative Neurophysiological Monitoring (IONM) used during surgeries involving the brainstem, skull base or cranial nerves. It allows real-time assessment of nerve activity, helping surgical teams avoid damage to critical functions such as hearing, facial movement, speech and swallowing.

At MediServices, we deliver cranial monitoring support through flexible insourced or fully outsourced models working alongside neurosurgical and ENT teams to improve surgical outcomes and preserve quality of life for patients.

What Is Cranial Monitoring?

Cranial Monitoring tracks the electrical activity of one or more cranial nerves during surgery using techniques such as:

• Electromyography (EMG)
• Auditory Brainstem Response (ABR)
• Facial nerve monitoring

Monitoring is performed by a trained neurophysiologist who communicates continuously with the surgical and anaesthetic team.

When Is Cranial Monitoring Used?

Cranial nerve monitoring is recommended in surgeries that carry a risk of damaging motor, sensory or mixed cranial nerves. These include:

• Acoustic neuroma and vestibular schwannoma removal
• Brainstem or posterior fossa tumour surgery
• Parotidectomy and facial nerve dissection
• Skull base or brainstem vascular procedures
• ENT, maxillofacial, or neurovascular interventions involving nerve risk

By providing instant feedback on nerve function, cranial monitoring helps reduce the risk of permanent sensory or motor deficits.

Insourced Support

• Our neurophysiologists work within your theatre team
• You provide theatre space and patient scheduling; we supply staff, equipment, and reporting

Outsourced Service

• We manage the entire IONM pathway from staffing and equipment to post-operative documentation
• Best for NHS teams without dedicated cranial monitoring capacity

All services are delivered under consultant supervision and follow NHS-compliant documentation standards.
