5.Conclusion
Early detection of RPA may lead to improved facial nerve outcomes because large recurrences may encroach the facial nerve and thus be more difficult to dissect. We performed a radiological follow up study on a relatively large cohort of patients who underwent minimally invasive parotid surgery (CD) for a PA. We have not been able to detect subclinical recurrences. Regular ultrasound examination after parotid surgery for PA is less invasive and may offer an early detection tool. Long term studies are necessary to prove or refute the clinical benefit and the cost-effectiveness of radiological follow up strategies.
