Chapter 3.2 Open
Looking at the group of patients with transient weakness of the facial nerve, 42.4% of patients had been operated by a transparotid approach, 34.5% by a non-transparotid approach, and in 23.2% the approach was not described. With regard to permanent facial nerve weakness, 11.8% of cases occurred after a transparotid approach, while 64.7% occurred after a non-transparotid approach. Of the total group of patients, 0.07% had permanent damage of the facial nerve after a transparotid approach, and 0.4% after a non-transparotid approach. No explanation for these outcomes was given, but one possible cause for damage to the facial nerve might be traction on the nerve.
