Summary
A patient developed facial palsy after glomus tumour embolization due to polyvinyl alcohol foam blocking the stylomastoid artery. This highlights the importance of understanding facial nerve blood supply variations during embolization procedures.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Neurology
Background:
- Glomus tumours, often vascular, require pre-operative embolization to reduce surgical bleeding.
- Facial palsy is a potential complication following head and neck procedures, including embolization.
Observation:
- A case of a patient developing facial palsy one hour post-embolization for a glomus tumour is reported.
- The palsy was attributed to embolization material obstructing the stylomastoid artery.
Findings:
- Polyvinyl alcohol foam used for embolization was identified as the cause of the arterial blockage.
- The stylomastoid artery, a key blood supply to the facial nerve, was compromised.
Implications:
- This case underscores the critical need for detailed anatomical knowledge of facial nerve vascularization in interventional procedures.
- Careful selection and delivery of embolic agents are crucial to prevent neurological complications like facial palsy.
- Enhanced understanding of facial nerve blood supply variations can improve patient safety during glomus tumour treatment.
