To the Editor. —With great interest I read the paper "Alteration of the Orbicularis Oculi Reflex by Acoustic Neuroma" by Drs. Lynn W. Lyon and Maurice W. Van Allen of Iowa City (Arch Otolaryngol 96:100-103, 1972).

In this article they reported a "new" technique which they suggest might be useful for the early diagnosis of acoustic neuroma. They give credit to Kimura et al, for describing the technique in 1969. Both groups of investigators were apparently unaware that this technique had been reported in the Archives of Otolaryngology in June 1966, (83:102-104) "Intracranial Removal of Acoustic Tumors" by John F. Mullan, MD.

Through the years, in an attempt to make the earliest possible diagnosis of acoustic neuroma in the most expedient way, we have investigated a number of diagnostic procedures. The blink reflex was intensively evaluated, first by high-speed photography and later utilizing electromyographic techniques, as suggested in the paper
