We studied 28 patients with herpes zoster oticus prospectively over the six‐year period between August 1974 and June 1980. We found that the results of measuring tear production, submandibular salivary flow, the response to maximal stimulation, and evoked electromyography gave us sufficient information to group these patients according to prognosis — either unfavorable or favorable —for spontaneous return of facial function. When the test results were 26% or more of normal, 100% of the patients had complete recovery without treatment; when the test results were 25% or less of normal, 69% had incomplete recovery: 19% had fair and 50% had poor recovery. Of the 31% with complete recovery, 4 were operated upon. The natural history of herpes zoster oticus in patients with a poor prognosis was improved if a transmastoid extralabyrinthine subtemporal decompression of the labyrinthine segment of the facial nerve was performed within 10 days of onset of the paralysis. The decision to perform this surgery was based upon the results of the prognostic tests mentioned above.
