ClinConnect Summary

This clinical trial is studying a new imaging technique called 3D MR Neurogram, which helps doctors see the tiny branches of facial nerves near parotid tumors better than traditional methods. The parotid gland is located near the jaw and can develop both benign (non-cancerous) and malignant (cancerous) tumors. When surgeons remove these tumors, there is a risk of damaging the facial nerves, which can lead to temporary or permanent facial weakness. The goal of this trial is to see if using this advanced MRI technique can help doctors visualize the nerves more clearly during surgery, potentially reducing the risk of nerve injury.

To participate in this study, patients aged 65 and older who have been diagnosed with a parotid tumor through other imaging tests (like ultrasound or CT scans) may be eligible. However, individuals with certain conditions that prevent them from having an MRI or those who are unable to provide consent will not be included. Participants will undergo MRI scans to help map the nerves before their surgery. This could lead to safer surgical procedures and better outcomes for patients with parotid tumors.

Eligibility criteria

• Inclusion Criteria:
• • Consecutive patients with parotid tumour diagnosed on other imaging modalities (such as ultrasonography or computed tomography), with or without cytological diagnosis from fine needle aspiration, will be recruited from the ear, nose and throat specialty clinic.
• Exclusion Criteria:
• • Patients who are contraindicated to magnetic resonance imaging (such as due to underlying MRI incompatible metallic implants)
• • Patient who are contraindicated to MRI contrast agents (such as advanced renal failure or previous severe allergic reaction)
• • Patients who cannot cooperate for MRI scanning.
• • Patients show are unable to provide informed consent.
