Answer

Surgery may be considered in patients with complete Bell palsy that has not responded to medical therapy and with greater than 90% axonal degeneration, as shown on facial nerve EMG within 3 weeks of the onset of paralysis. [63, 31] The problem must be localized with MRI. The surgeon can then decide if the maxillary segment should be decompressed externally or if the labyrinthine segment and geniculate ganglion should be decompressed with a middle fossa craniotomy.
