[Trigemino-facial reflex as a diagnostic aid in Recklinghausen's neurofibromatosis].

The blink reflex evoked by unilateral electrical stimulation was studied in 7 patients with Neurofibromatosis and 50 normal persons. Studing data of the early R1 reflex, there was no difference between normal persons and patients with von Recklinhausen disease. A slightly, but significantly increased reflex latency of the direct R2 was recognized in the majority of the patients with Neurofibromatosis.
