Highlights • Bilateral simultaneous facial palsy is a very rare condition. Its incidence is one per 5 000 000 per year.• Treatment protocols are generally based on onset of facial weakness (immediate or delayed) and extent of facial weakness.• Surgical approach remains controversial; transmastoid, middle fossa craniotomy or a combination of both.• It is important to discuss timing and expectations with the patient, keeping in mind that the return of maximal facial nerve function may take up to 12 months.
