Radical intracapsular microenucleation technique for exclusively intraparotid facial nerve schwannoma: Long-term follow-up review.

•We focused on facial nerve schwannomas with exclusively intraparotid involvement.•Facial nerve schwannoma was always misdiagnosed as a parotid tumor.•Intracapsular microenucleation offers a favorable outcome of facial nerve function.•Tumor recurrence was not observed with an average followed up for 5.75 years.
